[硬件改造] 最近在研究wsc的液晶屏 0624更新

WonderSwan has a display resolution of 224x144.

Display Hardware
The WonderSwan series used 3 types of LCD display throughout its lifetime.

The original WonderSwan used a monochrome FSTN (filtered super-twisted nematic) LCD display capable of displaying 16 shades of grey.

The WonderSwan Color used a CSTN (color super-twisted nematic) LCD display capable of displaying 12-bit color (4096 colors).

The SwanCrystal used a TFT (thin film transistor) LCD display also capable of displaying 12-bit color. The superior viewing characteristics of the TFT technology makes it the superior system in terms of visibility.

The (basic) display timing is something like this:

    0            224 256
