GENERAL DESCRIPTION
Panelview provides optically enhanced solutions to the standard Sharp LQ5AW136 color active matrix LCD module. The first enhancement is an index matching (IM) film lamination to the front surface of the display polarizer. The IM film is available in two surface treatments - IM/Clear and IM/110 (a 10% diffusion).The second enhancement is the incorporation of a reflective polarizer (RP) to improve brightness by up to 40%. The third enhancement is the addition of prism films (RPp) further increasing the brightness of the display. The module accepts full color video signals conforming to the NTSC(M) and PAL(G-B) system standards. It can withstand an intense environment, the online dimension is suitable for an automotive display, compact size, compatible with 2DIN size. Panelview assumes no responsibility for any damage resulting from the use of the device which does not comply with the instructions and the precautions specified in these specification sheets. Panelview does assume the responsibility for the warranty of the enhanced product.

Note: 1. If CKC='Hi', this terminal outputs horizontal sync. signal in phase with VBS. If CKC='Lo', this terminal will be external horizontal sync. input terminal. 2. If CKC='Hi', this terminal outputs vertical sync. signal in phase with VBS. If CKC='Lo', this terminal will be external vertical sync. input terminal. 3. PWM signal is used for the PWM dimming frequency and it is easy to get PWM signal dimming by combining both HSY and PWM signals. But use this PWM signal in case of input standard NTSC or PAL signal. 4. This terminal is to switch the display mode, and it is NTSC mode when NTP is 'High' and is PAL mode when NTP is 'Low'. 5. When this terminal is 'High', it will be normal and when it is 'Low', it will display reversely on the horizontal direction. 6. When this terminal is 'High', it will be normal and when it is 'Low', it will display reversely on the vertical direction. 7. This terminal is to switch input for groups of RGB color video signals, and Input 1 (No. 13 to 15) is selected when VSW is 'High' and Input 2 (No. 17 to 19) is selected when VSW is 'Low'. 8. This terminal switches to sampling mode. It is the independent data-sampling timing at RGB dot when SAM is 'High' and it is the simultaneous data-sampling timing at RGB dots when SAM is 'Low'. 9. This terminal is applicable to the DC bias voltage adjusting terminal of the common electrode driving signal. If power supply voltage is typical, it is not necessary to re-adjust it. So, Use it in the open condition. However, in the case that the power supply voltage is changed, or power supply voltage is reduced, adjust it externally to get the best contrast with a resistor that is added to this terminal, or semi-fixed resistor, VCDC in module. A recommended circuit is shown in Fig. 5. 10. The sync. signal which will be input, is negative polarity and is applicable to standard composite sync. signal, negative one in the same pulse level. 11. DC voltage supplied to this terminal, makes the brightness of the screen adjustable, which is the black level of the video signal. Although this is adjusted in the time of delivery to get the best display in the condition of the open terminal, it is also able to be re-adjusted externally with a resistor that can be added to this terminal, or a semi-fixed resistor, BRT, in module. A recommended circuit is shown in Fig. 5. 12. CKC-'Hi', CK.HSY.VSY terminals are output mode. CKC='Lo': CK. HSY. VSY terminals are input mode. 13. If CKC='Hi', this terminal outputs the clock for sure drivers. If CKC='Lo', this terminal will be the external clock input terminal.

DISPLAY QUALITY
The display quality of the color TFT-LCD module shall be in compliance with the Incoming Inspection Standards.
ENH050Q1-320/450/600
a) Floor: Conductive treatment of 1M or more on the title (conductive amt of conductive paint on the tile) b) Clean room free from dust and with an adhansive mat on the doorway c) Advisable humidity:50%~70% Advisable temperature:15C~27C d) Workers shall wear conductive shoes, conductive work clothes, conductive gloves and an earth band. If the TFT-LCD module metal parts (shielding lid and rear case) become soiled, wipe them with a soft dry cloth. Wipe off water spots of finger grease immediately. Prolonged contact with water may cause discoloration or spots. The TFT-LCD module uses glass which breaks or cracks easily if dropped or bumped on a hard surface. Handle with care. Since CMOS LSI is used in this module, take care of static electricity and ground one's body when handling.
HANDLING INSTRUCTIONS
Mounting the module
The TFT-LCD module is designed to be mounted on equipment using the mounting tabs in the four corners of the module at the rear side. When mounting the module, the M2.6 tapping screw (fastening torque is 0.3 through 0.5N*m) is recommended. Make certain to fix the module on the same plane. Avoid warping or twisting the module.
PRECAUTIONS IN MOUNTING
Polarizer which is made of soft material and susceptible to flaws must handled carefully. A protective film (Laminator) is applied on the surface to protect it against scratches and dirt. It is recommended to peel off the laminator immediately before use, taking care of static electricity. Precautions in peeling off the laminator A) Working environment When the laminator is peeled off, static electricity may cause dust to stick to the polarizer surface. To avoid this, the following working environment is desired.

Precautions in Adjusting Module
Variable resistor on the rear face of the module has been adjusted optimally before shipmetn. Therefore, do not change any adjusted values. If adjusted values are changed, the specifications described here may not be satisfied.

SHIPPING REQUIREMENTS
Carton storage conditions: Number of layers of carton in stack: 10 layers max Environmental conditions: Temperature: Humidity: 0~40C 60%RH or less (at 40C)
Caution of Product Design
1. The LCD module shall be protected against water by the waterproof cover.
Others
1. Do not expose the module to direct sunlight or intensive ultraviolet rays for many hours; liquid crystal is deteriorated by ultraviolet rays. 2. Store the module at a temperature near room temperature. When stored at lower than the rated storage temperature, liquid crystal solidifies, causing the panel to be damaged. When stored at higher than the rated storage temperature, liquid crystal turns into isotropic liquid and may not recover. 3. If LCD panel breaks, the liquid crystal could possibly escape from the panel. Since the liquid crystal is injurious, avoid contact with the eyes or mouth. Wash with soap immediately if contact with the liquid crystal occurs. 4. Observe all other precautionary requirements in handling general electronic components.
No dew condensation at low temperature and high humidity, Atmosphere Harmful gases such as acid and alkali which corrode electronic components and wires must not be present. Approximately 3 months To prevent TFT-LCD module from being damaged by static electricity, adjust the room humidity to 50%RH of higher and make certain one is grounded before opening the package.

ADJUSTING METHOD OF OPTIMUM COMMON ELECTRODE DC BIAS VOLTAGE
Normal line Photodetector (including luminosity factor)
To obtain optimum DC bias voltage of common electrode driving signal (VCDC). Photo-electric devices are very effective, and the accuracy is within 0.1V. (In visual examination method, the accuracy is about 0.5V because of the difference amoung individuals.) To gain optimum common electrode DC bias voltage, there is the following method which uses the photoelectric device. (Measurement of flicker) DC bias voltage is adjusted so as to minimize NTSC: 60Hz (30Hz) PAL: 50Hz (25Hz) flicker.
Photo-electric device Output voltage
Polarizing filter
Frame LCD panel Backlight (Plane source)

Brightness: Less than 5000cd/m2 Wave length: To be cut less than 400nm
Oscilloscope (X-Y recorder)

Fig. 9 Optical characteristics
Photo-electric output voltage is measured by an oscilloscope at a system shown in Fig. A. DC bias voltage must be adjusted so as to minimize the NTSC:60Hz(30Hz) PAL:50Hz(25Hz) flicker with DC bias voltage changing slowly. (Fig. B)
DC bias: Optimum
DC bias: Optimum + 1V
