LP104S5 LP104S5- -A2VT A2VT Liquid Crystal Display Liquid Crystal Display Product Specification Product Specification 1. General Description The LP104S5 - A2VT is a Color Active Matrix Liquid Crystal Display with an integral Cold Cathode Fluorescent Lamp(CCF L ) backlight system. The matrix employs a - Si Thin Film Transistor as the active element. It is a transmis s ive type display operating in the normally white mode. This TFT - LCD has a 10.4 inch es diagonally measured active display area wi th SVGA resolution( 600 vertical by 800 horizontal pixel array). Each pixel is divided into Red, Green and Blue sub - pixels or dots which are arranged in vertical stripes. Gray scale or the brightness of the sub - pixel color is determined with a 6 - bit gray scale signal for each dot, thus, presenting a palette of more than 262,144 colors. The LP104S5 - A2VT is intended to support applications where thin thickness is critical factors and graphic displays are important. In combination with the vertical arrangeme nt of the sub - pixels, the LP104S5 - A2 VT characteristics provide an excellent flat panel display for office automation products such as Notebook PC.

LP104S5 LP104S5 --A2VTA2VT Liquid Crystal Display Liquid Crystal Display Product SpecificationProduct Specification 3. Electrical Specifications 3 - 1. Electrical Characteristics The LP104S5 - A2VT requires two power inputs. One is employed to power the L CD electronics and to drive the TFT array and liquid crystal. The second input which powers the CCFL, is typically generated by an inverter. The inverter is an external unit to the LCD.

The performance of the Lamp in LCM,for example life time or brightness,is extremely influenced by the characteristics of the DC - AC Inverter.So all the parameters of an inverter should be carefully designed so as not to produce too much leakage current from high - voltage output of the inverter. When you design or order the inverter,please make su re unwanted lighting caused by the mismatch of the lamp and the inverter(no lighting,flicker,etc) never occurs.When you confirm it,the LCD Assembly should be operated in the same condition as installed in your instrument. 1. The specified cur rent and power consumption are under the Vcc = 3.3V , 25 °C , fv = 60Hz condition whereas mosaic pattern is displayed. 2 . The duration of rush current is about 20ms. 3. The variance of the voltage is ±10%. 4 . The voltage above V s sho uld b e applied to the lamps for more than 1second for start - up. Otherwise,the lamps may not be turned on. 5. The output of the inverter must have symmetrical(negative and positive) voltage waveform and symmetrical current waveform.(Unsymmetric al ratio is less than 10%) Please do not use the inverter which has unsymmetrical voltage and unsymmetrical current and spike wave. Lamp frequency may produce interference with horizontal synchronous frequency and as a result this may cause beat on the display. Therefore lamp frequency shall be as away as possible from the horizontal synchronous frequency and from its harmonics in order to prevent interference. 6. Let ’s define the brightness of the lamp after being lighted for 5 minutes as 100%. T s is the time required for the brightness of the center of the lamp to be not less than 95%.
LP104S5 LP104S5- -A2VT A2VT Liquid Crystal Display Liquid Crystal Display Product Specification Product Specification 7 . The lamp power consumption shown above does not include loss of external inverter. 8 . The life time is determined as the time at which brightness of lamp is 50% compare d to that of initial value at the typical lamp current on condition of continuous operating at 25 ±2°C .

LP104S5 LP104S5- -A2VT A2VT Liquid Crystal Display Liquid Crystal Display Product Specification Product Specification 9.PRECAUTIONS Please pay attention to the followings when you use this TFT LCD module.
9.1 MOUNTING PRECAUTIONS
(1) You must mount a module using holes arranged in four corners or four sides. (2) You should consider the mounting structure so that unev en force (ex. twisted stress) is not applied to the module. And the case on which a module is mounted should have sufficient strength so that external force is not transmitted directly to the module. (3) Please attach a transparent protective pl ate to the surface in order to protect the polarizer. Transparent protective plate should have sufficient strength in order to resist external force. (4) You should adopt radiation structure to satisfy the temperature specification. (5) Acetic acid type and chlorine type materials for the cover case are not desirable because the former generates corrosive gas of attacking the polalizer at high temperature and the latter causes circuit break by electro - chemical reaction. (6) Do not touch, push or rub the exposed polarizers with glass, tweezers or anything harder than HB pencil lead. And please do not rub with dust clothes with chemical treatment. Do not touch the surface of polarizer for bare hand or greasy cloth. (Some cosmetics are de trimental to the polarizer.) (7) When the surface becomes dusty, please wipe gently with absorbent cotton or other soft materials like chamois soaked with petroleum benzene. Normal - hexane is recommended for cleaning the adhesives used to attach fr ont / rear polarizers. Do not use acetone, toluene and alcohol because they cause chemical damage to the polarizer. (8) Wipe off saliva or water drops as soon as possible. Their long time contact with polarizer causes deformations and color fading. (9) Do not open the case because inside circuits do not have sufficient strength.
9.2 OPERATING PRECAUTIONS
(1) The spike noise causes the mis - operation of circuits. It should be lower than following voltage : V = ± 200mV (Over and under shoot voltag e). (2) Response time depends on the temperature. (In lower temperature, it becomes longer.) (3) Brightness depends on the temperature. (In lower temperature, it becomes lower.) And in lower temperature, response time (required time that brigh tness is stable after turned on ) becomes longer. (4) Be careful for condensation at sudden temperature change. Condensation makes damage to polarizer or electrical contacted parts. And after fading condensation, smear or spot will occur. (5) When fixed patterns are displayed for a long time, remnant image is likely to occur. (6) Module has high frequency circuits. Sufficient suppression to the electromagnetic interference shall be done by system manufacturers. Grounding and shielding methods may be important to minimize the interference. Alpha Point Ltd.

LP104S5 LP104S5- -A2VT A2VT Liquid Crystal Display Liquid Crystal Display Product Specification Product Specification
9.3 ELECTROSTATIC DISCHARGE CONTROL
Since a module is composed of electronic circuits, it is not strong to electrostatic discharge. Make certain that treatment persons are connected to ground through wr ist band etc . And don’t touch interface pin directly.
9.4 PRECAUTIONS FOR STRONG LIGHT EXPOSURE
Strong light exposure causes degradation of polarizer and color filter.
9.5 STORAGE
When storing modules as spares for a long time, the following precautio ns are necessary. (1) Store them in a dark place. Do not expose the module to sunlight or fluorescent light. Keep the temperature between 5 °C and 35 °C at normal humidity. (2) The polarizer surface should not come in contact with any other object. It is recommended that they be stored in the container in which they were shipped.
9.6 HANDLING PRECAUTIONS FOR PROTECTION FILM
(1) When the protection film is peeled off, static electricity is generated between the film and polarizer. This should be pee led off slowly and carefully by people who are electrically grounded and with well ion - blown equipment or in such a condition, etc. (2) The protection film is attached to the polarizer with a small amount of glue. If some stress is applied to rub the protection film against the polarizer during the time you peel off the film, the glue is apt to remain on the polarizer. Please carefully peel off the protection film without rubbing it against the polarizer. (3) When the module with protection film attached is stored for a long time, sometimes there remains a very small amount of glue still on the polarizer after the protection film is peeled off. (4) You can remove the glue easily. When the glue remains on the polarizer surface or its vesti ge is recognized, please wipe them off with absorbent cotton waste or other soft material like chamois soaked with normal - hexane .
