GENERAL DESCRIPTION
WEDC provides optically enhanced solutions to the standard Optrex AA104VB05 color TFT-LCD (Thin Film Transistor Liquid Crystal Display) module. The first enhancement is an index matching (IM) film lamination to the front surface of the display polarizer. The IM film is a contrast enhancement benefit and is available in two surface treatments - IM/Clear and IM/110 (a 10% diffusion).The second enhancement is the incorporation of reflective polarizer (RP) to improve brightness by up to 40%. The third enhancement is the incorporation of an enhanced light guide (ELG) to improve brightness by up to 35%. The resultant brightness level are shown in the Specifications below. This module is composed of a color LCD panel, driver ICs, control circuit, and a backlight unit. By applying 6 bit digital data 640 x 480, 260K-color images are displayed on the 10.4" diagonal screen. Input power voltage is single 3.3V/5V for LCD driving. Both 3.3V-CMOS and 5.0V-CMOS level voltage are acceptable for logic input voltage. Inverter for backlight is not included in this module. General specifications are summarized in the following table:

Notes: 1. Lamp current measurement method (The current meter is inserted in low voltage line.) 2. Lamp frequency of inverter may produce interference with horizontal synchronous frequency,and this may cause horizontal beat on the display. Therefore, please adjust lamp frequency, and keep inverter as far from module as possible or use electronic shielding between inverter and module to avoid the interference. 3. Lamp life time is defined as the time either when the brightness becomes 50% of the initial value, or when the starting lamp voltage does not meet the value specified in this table. 4. The life time of the backlight depends on the ambient temperature. The life time will decrease under low/high temperature.
