8.0吋寬溫彩色TFT LCD, WVGA廣溫 LCD, 觸控面板(選項)

Model No.VGG804812-H(WT)

► WVGA (800×480 pixels) resolution.
► Digital 24 bit parallel RGB.
► Dot inversion mode with stripe type.
► LED driver circuit is built in this module to provide PWM Dimmer function.

VGG804812-H是一款8.0吋寬溫彩色TFT LCD ，其規格非常適合應用於廣溫環境下需要TFT LCD顯示的產品，在影像資料傳輸上支援TTL RGB介面。在產品操作使用上其工作溫度是-30~80℃，儲存溫度是-30~80℃。

目前市面上常見的TFT LCD模組產品對於寬溫的定義範圍為-20~70℃，而針對工控、車載、室外產品的應用，其這樣的溫度範圍往往並不能符合該類產品應用的需求。因應客戶的需求，億力光電推出一系列超廣溫 TFT 液晶模組顯示器，其模組操作溫度可到達超廣溫-30℃ 至 +80℃，部分型號高溫更可到達85℃。

Note 1:	DE/SYNC mode select. Normally pull high.
	- When select DE mode, MODE=”1”, VS and HS must pull high.
	- When select SYNC mode, MODE= ”0”, DE must be grounded.
Note 2:	On/Off Control Input and Dimming Command Input.
	- A voltage greater than 0.7V will turn on the chip.
	- When the BLEN pin voltage rises from 0.7V to 1.4V,The LED current will change from 0% to 100% of the maximum LED current.
	- To use PWM dimming, apply a 100Hz to 1kHz square wave signal with amplitude greater than 1.4V to this pin. To use PWM dimming, apply a 100Hz to 1kHz square wave signal with amplitude greater than 1.4V to this pin.
