Abstract
A liquid crystal display (LCD) apparatus includes a backlight module and a LCD module. The backlight module has a plurality of individually drivable backlight regions. The LCD module has a plurality of display blocks, each of which corresponds to one of the backlight regions and is disposed on an optical path of light emitted from the corresponding backlight regions. A power regulating module is electrically connected to the backlight module and the LCD module for receiving image frame data and controlling light-emitting intensities of the backlight regions in accordance with the image frame data to be displayed by the corresponding display blocks. Each backlight regions has multiple light-emitting units for emitting light in different colors. Each display block has a plurality of pixels, and each of the pixels has multiple filter units. A transmitted spectrum of each of the light-emitting units of the backlight regions corresponds to transmitted spectrums of at least two filter units of each of the pixels in the respective display blocks.
