SHARP SPEC No. MODEL No. PAGE LC99908 LM057QClT03 1 I I Precautions 1) When design the product with this LCD module, make sure the viewing angle matches to its purpose of usage. Viewing angle of this LCD module is illustrated in Fig. 1. 8yMIN.<viewingangle<OyMAX. (For the specific values of 6 y MIN., and 8 y MAX., refer to the table 9 ) Consider the optimum viewing conditions according to the purpose when installing the module. Viewing direction + 6 y Panel surface ormal line) . . . . Ei~-14 Definttlonofwe~ 2) This LCD module must be mounted using mounting holes of metal bezel. Handle carefully when install the LCD module to avoid unnecessary stresses such as twisting or bending. 3) If the surface of LCD panel needs to be cleaned, wipe it swiftly’with cotton or other soft cloth If it is not still clean enough, blow a breath on the surface and wipe again 4) Water droplets must be wiped off immediately as those may leave stains or cause color changes if remained for a long time. 5) As LCD panel is made of glass substrate, dropping the LCD module or banging it against hard objects may cause cracking or fragmentation.
@HARP SPEC No. MODEL No. PAGE LC99908 LM057QCTT03 2 6) As CMOS LSIs are equipped in this module, following countermeasures must be taken to avoid electrostatics charges. 1. Operator Ware the electrostatic shielded clothes because human body may be statically charged if not ware shielded clothes. 2. Equipment There is a possibiiity that the static electricity is charged to the equipment which have a function of peeling or friction action(ex: conveyer, soldering iron, working table). Earth the equipment through proper resistance(electrostatic earth: 1 X 10” 9). 3. Floor Floor is the important part to drain static electricity which is generated by operators or equipment. There is a possibility that charged static electricity is not properly drained in case of insulating floor. Set the electrostatic earth(1 X lO”S2). 4. Humidity Proper humidity helps in reducing the chance of generating electrostatic charges. Humidity should be kept over 50%RH. 5. Transportation/storage The storage materials also need to be anti-static treated because there is a possibility that the human body or storage materials such as containers may be statically charged by friction or peeling. 6. Others The laminator@rotective film) is attached on the surface of LCD panel to prevent it from scratches or stains. It should be peeled off slowly using static eliminator. Static eliminator should also be installed to the work bench to prevent LCD module from static charge. 7) Do not use any materials which emit gas from epoxy resin(hardener for amine) and silicone adhesive agent(dealcoho1 or deoxym) to prevent discoloration of polarizer due to gas. 8) The brightness of the LCD module may be affected by the routing of CCFI cables due to leakage to the chassis through coupling effect. The inverter circuit needs to be designed taking the level of leakage current into consideration. Thorough evaluation is needed for LCD module and inverter built into its ho& equipment to ensure specified brightness. 9) Avoid the exposure of the module to the direct sun-light or strong ultraviolet light for a long time. 10) If the LCD module is stored at below specified temperature, the LC material may freeze and be deteriorated If it is stored at above specified temperature, the molecular orientation of the LC material may change to Liquid state and it may not revert to its original state. Therefore, the LCD module should always be stored within specified temperature range. 11) Disassembling the LCD module can cause permanent damage and it should be strictly avoided
@HARP SPEC No. MODEL No. PAGE LC99908 LM057QCTT03 3 12) Procedure to insert mating connector When the mating connector is inserted, it should be parallel to the connector on the LCD module and it should be inserted horizontally. Do not leave a gap beh>een two connectors. 13) The module should be driven according to the specified ratings to avoid malfunction and permanent damage. Applying DC voltage causes a rapid deterioration of LC material. Make sure to apply alternating waveform by continuous application of the M signal. Espe&&& power ON/OFF sm 17 &n&l& t to avov DC m 14) LCD retains the display pattern when it is applied for long time.(Image retention) To prevent image retention. do not apply the flied pattern for along time. 15) Image retention is not a deterioration of LCD. It will be removed after display pattern is changed 16) CCFI’ backlight should be kept OFF during VDD is “L” level. Precautions for touch panel 1) Designing 1. Active area Active area is defined as input area by pen or finger. Its function, optical properties and durability are specified in the specifications. a) Detection of coordinates and calbration must always be conducted within active area. If those are conducted outside of the active area, those may cause functional errors. b) Area which is actually accessed by pen or finger must be designed within active area. If it is designed outside of the active area, it may cause functional error. 2.Neutral area Neutral area is located around the active area for l.Omm wide. Although the coordinates can be detected in this area, its functionality, optical properties and durability are not assured. a) Neutral area detects coordinates when input by pen or finger, but it may cause functional error when it is treated as detected data. b) As the purpose of the neutral area is to protect inactive area, pushing hardly by pen tip or others may cause deterioration of its durability. 3.Visible area This is transparent area where silver electrode or flex printed with opaque ink are not existing. It assures qualities related to appearance standards defined in the specifications. 4Jnactive area Upper electrode or lower electrode in the inactive area is printed with transparent insulation ink on it. It is located outside of the active area and a non functional area. a) Inactive area is printed with insulation ink. Hard push action may cause a deformation of upper electrode film and may lead to a malfunction in the active area nearby. Upper electrode may come J
@HARP SPEC No. MODEL No. PAGE LC99908 LM057QCTT03 4 r I I in contact with lower electrode and may cause a electrical leakage. b) As the purpose of the inactive area is to keep the flatness of the upper electrode ftirn in the touch panel structuie. hard push by pen or by system chassis may cause a functi&al error. Designing print circuit 1. There is a contact resistance between upper and lower electrodes of the touch panel. It is recommended to set the impedance of detecting circuit high enough. Low impedance detecting circuit may cause a functional error. 2. Contact of the upper and lower electrode generates a contact resistance. Access by pen or finger to the touch panel should be started after the contact resistance becomes stable. Otherwise, it may cause a functional error. 3. Touch panel picks up a noise easily. It is recommended to earth or do other noise protections. Otherwise, it may cause a functional error. Designing system chassis 1. Retain the air gap between upper electrode film and front chassis. a) Retain minimum of 0.3mm air gap above the inactive area so that the front chassis does not make a pressure on upper electrode film. If there is any pressure on it, it may cause a functional error due to the deformation of the upper electrode film. b) Flexible material such as rubber is recommended as cushioning materials. It should be placed outside of visible area. If it is placed onto inactive area, it may cause a functional error due to deformation of the upper electrode film. 2. Assemble design a) Do not glue nor tape system front chassis to the surface of touch panel(upper electrode fam) as it may lead to peeling off of the upper electrode film b) Make sure not to swell the upper electrode film by atmospheric pressure difference between inside and outside of the system. If it is swelled, it may cause a deterioration of durability of the touch panel and may cause a functional error. c) Prevent vapor condensation to the touch panel. Do not expose the touch panel to high humidity Atmosphere, vaporous air, or to any liquid such as water. It may cause a leakage inside the touch panel structure: Upper electrode film and lower electrode glass are fied by adhesive, and there is a ventilation hole between film and glass. Liquid penetrate into touch panel easily due to this structure. Design the system carefully so that liquid will not penetrate into touch panel.
SHARP SPEC No. LC99908 iMODEL No. PAGE LM057QCTT03 5 Assembling LCD module with touch panel * 1. Unpacking a) Do not hold nor pull flex cable. otherwise it may cause a breakage of the flex. b) Glass edge of touch pane1 is not treated It is sharp edge and it may cause an injury when handled by bare hands. Wear finger sacks or groves and handle with extra care. 2. Handling a) Do not pick up the visible area or flexible tail. b) Do not stack up the LCD module. Do not place anything on the LCD module. It may cause scratch, deformation or breakage. c) Wipe a dirt on the screen with dry soft cloth If it is still sticked, wipe it out with soft cloth with ethyl alcohol. Upper electrode film and lower electrode glass of touch panel are fixed by adhesive and there is a ventilation hole in between. Be careful not to have ethyl alcohol may penetrate into touch panel. It may cause a functional error. 3. Assembling a) Be careful not to apply excessive distortion on heat sealed area of the flex cable. It may cause a functional error. b) Be careful not to scratch the front of touch pane1 during assembly process. 4. Operating instruction a) Use a finger or a polyacetal pen to access to touch panel. The surface of the touch panel film is hard coat treated. This hard coating may be damaged if it is touched by a ball-point pen or metal piece. b) Do not expose the LCD module to the direct sun-light for long period of time. Polyester film is used as the front film of the touch panel, exposure to direct sun-light for long time may cause a discoloration c) If a chemical material stays on the touch panel for long period of time, front film may be swelled and may cause a functional error. If it is planned to be used under severer circumstances, very careful protection is required

Input data’and control signal One SEG(segment=column)driver is a 240 bit output LSI, consisting of shift registers, latch circuits and LCD driver circuits. Input data for each row (320 X 3[R,G,E?]) will be sequentially transferred in the form of 8 bit parallel data through shift registers by data transfer clock signal (XCK). When data transfer for one row (320 X 3[R.,G,B]) is completed, the data will be latched in the form of 320 x 3 parallel data corresponding to each column electrodes by the falling edge of latch signal (LP), then the drive pulses will be output to 320 X 3 lines of column electrodes of the LCD panel by the LCD drive circuits. At the same time. row N is selected by scan start-up signal (YD) and the contents of the data signals are displayed on the row N of the display screen according to the combinations of voltages applied to row and column electrodes. While the data row N are being displayed, data for row N+l are transferred After 320 X 3 data have been transferred, data will be latched by the falling edge of LP and output the data to the row N+l. Bach row will be sequentially selected as described above from N=l to N=240. One frame is completed after displaying 240”’ row. Then row scan starts from the 1st row again YD is the scan signal which drives row electrodes. If DC voltage is applied, it causes a chemical reaction in LC material and causes a deterioration of LC material. So, the polarities of driving pulses must be alternated by certain time period. Control signal M is the signal which changes the polarity of driving pulses. Power consumption of the LCD module goes up as clock(XCK) frequency goes up due to the nature of CMOS LSI used in it. This display module has 8 bit parallel data input so that it works at low clock frequency and rninin&e power consumption. 8 bit display data are assigned to DO-7. This display module also has a bus line system for data input to minimize the power consumption. Data input of each LSI driver works only when data is accessed Data Input for column electrodes and Chip Select of driver LSI work as follows: The driver LSI at the left end of the screen is selected first and 240 bits of data(30 x XCK) are transferred to it- After transferring 240 data, the adjacent right side LSI right is selected. This process is sequentially continued until data is fed to the LSI at the right end of the screen. Thus display data is transferred sequentially through 8 bit bus line from the left to the right of the screen.
