Patent ID: 8749471

Claim:
A liquid crystal display comprising: a display panel structured to display an image in response to gate line signals and data line signals; a panel driving circuit structured to receive an image signal, structured to receive at least one control signal, and structured to provide the gate line signals and the data line signal to the display panel according to the image signal and the at least one control signal; a backlight unit structured to provide illuminating light to the display panel for the display panel to display the image to a viewer of the display panel, the backlight unit including a plurality of light sources; and a backlight control circuit structured to detect existence of text information in the image signal, the backlight control circuit being further structured to determine a text information containing area where text in accordance with the text information will appear on the display panel, the backlight control circuit being further structured to determine a blinking-on timing of the light sources in accordance with the text information containing area, wherein the backlight control circuit is structured to output a timing control signal to synchronize the blinking-on timing of the plurality light sources, the timing control signal being delayed by a first time from a predetermined reference signal if the received image signal is determined to contain no text information, the timing control signal being delayed by a second time from the reference signal if the received image signal is determined to contain some text information in a position corresponding to the text information containing area, the second time being equal to or different from the first time.
