Winstar is going to upgrade the PCB board for all WH1602B and WH1602K series; running change from September, 2018. The mechanical outline dimensions and the electrical characteristics will be the same as the previous version, but the layout will look different. The upgraded PCB will improve the performance as below:
- Improving ESD protection: add ground jumpers for bezel (frame)/ mounting hole.
- For those using RW1603 IC modules, customers can select 8bit/4bit/ SPI/ I2C interface function by changing jumper.
- Adding decoupling capacitor: it filters out a certain frequency or range of frequencies which will improve the LCD modules stability.
- Increasing VOP internal adjustment circuit.
Affected Items: all WH1602B series, WH1602B1 series, WH1602B3 series, WHZ1602B series, WH1602K series LCD modules.
