Description:
TST043WQHS-105 is 480x272 resolution 4.3 inch lcd display module, coming out with SPI interface. this lcd screen module is with a high-performance TFT-LCD graphics accelerated display chip——LT7680. Its main function is to assist MCU to display the contents of the TFT screen to the TFT Driver. It provides graphics acceleration, PIP (picture-in-picture), geometry graphics and other functions, in addition to enhance the display efficiency, also greatly reduces the MCU processing graphics display time spent. It's also with high brighntess and temperature range.
