1. Application This specification applies to a color TFT-LCD module, QD26WL01 2. Overview This module is a color active matrix LCD module incorporating amorphous silicon TFT (Thin Film Transistor). It is composed of a color TFT-LCD panel; driver ICs, control circuit and power supply circuit and a backlight unit. Graphics and texts can be displayed on a 1280 method and supplying +12V DC supply voltage for TFT-LCD panel driving. The TFT-LCD panel used for this module has fast response time. A low-reflection and higher-colorsaturation type color filter is also used for this panel. Therefore, high-brightness and high-contrast image, which is suitable for multimedia use, can be obtained by using this module. [Features] 1) Brilliant and high contrast image. 2) Wide viewing angle. 3) Fast response time 4) WXGA resolution. 5) LVDS interface. 6) High color saturation 3. General Specifications Parameter

Lamp frequency may produce interference with horizontal synchronous frequency, and this may cause beat on the display. Therefore lamp frequency shall be detached as much as possible from the horizontal synchronous frequency and from the harmonics of horizontal
synchronous to avoid interference. Note4 Note5 The voltage above this value should be applied to the lamp for more than 1 second to startup. Otherwise the lamp may not be turned on. The life is determined as the time at which luminance of the lamp is 50% compared to that of initial value at the typical lamp current on condition of continuous operating at 25 2 C. Note) 1. The performance of the backlight, for example life time or brightness, is much influenced by the characteristics of the DC-AC inverter for the lamp. When you design or order the inverter, please make sure that a poor lighting caused by the mismatch of the backlight and the inverter (miss-lighting, flicker, etc.) never occur. When you confirm it, the module should be operated in the same condition as it is installed in your instrument. 2. Protection function : if one lamp cannot light on well, the inverter will shut down all lamps. 6-3.

as warp or twist.
c) Since the front polarizer is easily damaged, pay attention not to scratch it. d) Wipe off water drop immediately. Long contact with water may cause discoloration or spots. e) When the panel surface is soiled, wipe it with absorbent cotton or other soft cloth. f) Since the panel is made of glass, it may break or crack if dropped or bumped on hard surface. Handle with care. g) Since CMOS LSI is used in this module, take care of static electricity and injure the human earth when handling. h) Observe all other precautionary requirements in handling components. i) This module has its circuitry PCBs on the rear side and should be handled carefully in order not to be stressed. j) Laminated film is attached to the module surface to prevent it from being scratched . Peel the film off slowly just before the use with strict attention to electrostatic charges. Ionized air shall be blown over during the action. Blow off the 'dust' on the polarizer by using an ionized nitrogen gun, etc..
