Product Introduction - 3.5 inch TFT WF35R

Winstar WF35R is a 3.5 inch diagonal full color QVGA 320x240 TFT LCD module. This module is built in with SSD2119 IC; it includes the controller and driver IC functions and supports lots of different interfaces: 8/ 9/ 16/ 18-bit 6800-series and 8080-series parallel interface, 3-wire or 4-wire SPI, 18-bit/6-bit RGB interface. Since the WF35R doesn’t require control-board to drive MCU parallel and SPI interface, the advantage of WF35R is having competitive price than other TFT models which are require control-board on module. Below is the basic spec information for WF35R, please contact with us if you need further detailed information.

Product Introduction - Graphic COG LCD WO256128A

WO256128A is a monochrome graphic LCD module made of 256x128 pixels, diagonal size 2.9 inch. This LCD Module WO256128A is built in with ST75256 controller IC, it supports 6800 8-bit, 8080 8-bit parallel and 4-wire serial SPI and I2C interface. The WO256128A is having the same outline dimension, and VA size and same power supply 3.3V as WO12864D3, but is having a much higher resolution and performance. The WO125128A is an upgrade version of WO12864D3 to meet with the customers’ requirement on higher resolution and the best thing is that the customers don’t have to change the mechanical design for their applications.

This module can be operating at temperatures from -20℃ to +70℃; its storage temperatures range from -30℃ to +80℃. The WO256128A is available for different LCD mode options, STN Negative, FSTN Negative (Double film) and FSTN positive and with LED backlight options, like white LED.
