BTC070BB-GBR$ is 7.0" TFT LCD Module with 800*RGB*480 Resolution

It is a trasmissive normally white TFT with 4-Wire SPI Interface.

Controller IC used in TFT is RA8875

BTC070BB-GBR$ supports RTP (Resistive Touch Panel)


RA8875 is a text/graphic mixed display with 2 layers TFT LCD controller. It is designed to meet the requirement of middle size TFT module up to 800x480 pixels with characters or 2D graphic application. Embedded 768KB display RAM provides user a flexible solution for displaying buffer of almost application. Besides, optional external serial flash is capable to provide the up to 32x32pixels font bitmap for BIG5/GB coding. For graphic usage, RA8875 supports a 2D Block Transfer Engine(BTE) that is compatible with 2D BitBLT function for processing the mass data transfer. The advanced geometric speed-up engine provides user an easy way to draw the programmable geometric shape by hardware, like line, square, circle and ellipse. Besides, for different end-user applications, many powerful functions are integrated with RA8875, such as scroll function, floating window display, graphic pattern and font enlargement function. These functions will save user a large of software effort during development period.
