摘要： A driver adaptable to a debugging system includes a driver controller, and a driver general-purpose input and output (GPIO) controlled by the driver controller. The driver GPIO directly transfers a debug log of status messages of a touchscreen to a host general-purpose input and output (GPIO) of a host without handshaking between the driver and the host.

摘要： An apparatus for performing subpixel rendering of an RGBW display panel is provided. The apparatus receives an input gray level data to acquire a luminance value of each subpixel of a RGB pixel set including two RGB pixels adjacent to each other. The apparatus calculates a rendered luminance value of each subpixel of a display pixel set including two display pixels adjacent to each other according to the luminance values. The display pixel set of the RGBW display panel includes red, green, blue, and white subpixels. The rendered luminance value of the white subpixel of one of the display pixels is determined according to the saturation value of the corresponding RGB pixel and the luminance value of each subpixel of the corresponding RGB pixel. The apparatus acquires a gray level value of each white subpixel of the display pixel set according to the rendered luminance values.
