Abstract

The invention provides a viewing angle switching architecture, a method thereof and a liquid crystal display device thereof. The view switching architecture includes a timing control module, a first processing module, a second processing module, and a source driving module. The timing control module outputs a voltage call command, a first polarity control signal, and a second polarity control signal according to a mode control signal, and the first processing module outputs a first voltage generation command and a reset signal. The second processing module executes the first voltage generationcommand to output a plurality of external supply voltages, and a second group of gamma voltages and a third group of gamma voltages are alternately output to the source driving module according to the second polarity control signal. The source driving module receives the voltage call command and uses the internal gamma correction circuit, a plurality of external supply voltages can be received toobtain a first group of gamma voltages. The view switching architecture can support three groups of gamma voltages and support the switching use of two groups of gamma voltages in one display mode, and effectively improves the image quality of a display screen of a liquid crystal display device.

Description

Technical field [0001] The invention relates to the field of liquid crystal display, in particular to a viewing angle switching architecture, method and liquid crystal display device. Background technique [0002] Liquid Crystal Display (LCD) has the advantages of good image quality, small size, light weight, low driving voltage, low power consumption, no radiation, and relatively low manufacturing cost. It currently plays a dominant role in the field of flat panel displays. [0003] At present, the demand for image quality of liquid crystal display devices is getting higher and higher. Liquid crystal display devices often need to be operated in different display modes (such as wide viewing angle display mode, narrow viewing angle display mode), and different sets of display modes are required under different display modes. Gamma voltage, and sometimes in a display mode, it is necessary to switch between two groups of gamma voltages. figure 1 The gamma curve corresponding to the tw...
