Abstract
The invention provides a liquid crystal module and a backlight brightness control method thereof.The liquid crystal module comprises at least one control unit and at least one backlight source assembly, the control units and the backlight source assemblies are connected in pairs, and each control unit comprises an ambient light collection module used for collecting the light intensity of externalambient light and converting the light intensity into an electric signal; brightness adjusting module, the signal receiving module is used for receiving electric signals from the ambient light collection module; a control signal is generated at least based on the electric signal and a preset signal value; the backlight source assembly comprises a plurality of light-emitting elements. And the control module is used for receiving the control signal from the corresponding brightness adjusting module and entering a corresponding working state according to the control signal, and the working statecomprises a first working state in which all the light-emitting elements emit light at full power, a second working state in which all the light-emitting elements do not emit light and a third workingstate in which the light-emitting elements emit light at partial power. According to the invention, the power consumption of the high-brightness module used in a low-brightness state is effectively reduced, and the service life of the backlight source is prolonged.
Description
technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a liquid crystal module and a method for controlling the brightness of the backlight which take into account both ultra-high-brightness display and ultra-low-brightness display. Background technique [0002] Liquid crystal is an organic polymer material whose performance is between that of liquid and crystal. It has both the fluidity of liquid and the orderliness of crystal structure arrangement. Liquid crystals have a crystalline structure at low temperatures, become liquid at high temperatures, and exist in the form of liquid crystals at intermediate temperatures. With the rapid development of science and technology, people are more and more interested in the research and development of liquid crystal materials. The demand for liquid crystal displays in the world market is also increasing day by day, and now more and more liquid crystal displays and LCD TVs have...
