- Sunlight Readable 10.4" LCD Module Landmark Technology 2160 Old Oakland Rd. San Jose, CA 95131 (408) 434-9302 Fax: (408) 434-0954 07/99 Landmark Technology Introduction P2 LM073A-DC31 is a 10.4", high efficiency sunlight readable LCD module. The module consists of a Sharp LQ104V1DC31 TFT color LCD and a Landmark very high brightness (VHB) backlight mounted onto the back of the LCD. The entire module is about 0.9" thick and has the same foot print as the LQ104V1DC31 LCD. The Sharp LQ104V1DC31 LCD is a high contrast, wide viewing-angle LCD, and a 0 to 70o C extended operating temperature range. In the normal mode operation, the LM073A-DC31 module delivers 1,400 Cd/m2 (nits) LCD screen brightness at a backlight power of 19 Watts. With a dimming inverter, the module can be operated in a reduced brightness mode, for example at 1,000 nits, with lower power consumption and longer lamp life. In both modes, the display is highly readable under direct sunlight. In addition, the color tone of the “White” displayed on the LCD screen is closely matched to the color of normal sunlight. With a wide dimming range inverter, the LM073A-DC31 LCD module presents a surperb color image at 640 x 480 resolution over ambient illumination levels from full bright sunshine to total darkness, making it highly suitable for various outdoor applications.
