► 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.
