摘要： A controller switching a display mode of a display panel. A processor provides a first initial signal and switches to a first display mode when a select signal is asserted. A gate driver simultaneously activates the gate electrodes in a first gate electrode group when receiving the first initial signal, sequentially activates the gate electrodes in a second gate electrode group when the first gate electrode group is activated, and simultaneously activates the gate electrodes in a third gate electrode group when the second gate electrode group is activated. A data driver provides corresponding image data to a data electrode depending on the activated gate electrodes when the first, second, or third gate electrode group is activated.

摘要： A liquid crystal display has a backlight module and an indicator. The indicator is used to detect the light brightness of the backlight module, and announces a warning when the light brightness is lower than a predetermined value. The indicator has at least one color light detection unit that includes a detector, an analog-to-digital converter (ADC), a controller and a warning display. The detector detects the brightness of a color light from the backlight module to generate a light brightness voltage. The ADC converts the light brightness voltage into a digital signal. The controller determines whether the brightness of the color light is lower than the predetermined value or not according to the digital signal. When the brightness of the color light is lower than the predetermined value, the controller makes the warning display announce the warning.

The video processing chip outputs an adjusted image signal according to a video signal to an LCD panel to display an image. The video processing chip includes a video processor, a ratio detector, a timing controller, and a multiplexer. The video processor generates an image signal according to the video signal. The ratio detector detects the aspect ratio of the video signal, and outputs a ratio control signal according to a ratio setting value. The timing controller outputs a vertical blanking signal, a horizontal blanking signal, and a blanking data in responding to the ratio control signal. The multiplexer selects the blanking data signal or the image signal as the adjusted image signal to be outputted, so that the displayed image has the aspect ratio corresponding to the ratio setting value.
