Abstract

The invention discloses a liquid crystal display device and a narrow visual angle waveform self-adaption adjustment method thereof. The device comprises a trigger, an interrupt controller, a signal processor, a counter, a memorizer, a digital to analog converter and a display panel; the trigger detects trigger signals of a trigger waveform; the interrupt controller generates state mark information according to the obtained trigger signals; the signal processor controls the counter to count according to the state mark information generated by the interrupt controller; when the count of the counter reaches k*N, narrow visual angle waveform data is read from the memorizer, and the read narrow visual angle waveform data is sent to the digital to analog converter; the digital to analog converter receives the narrow visual angle waveform data sent by the signal processor, transforms the received narrow visual angle waveform data to waveform point voltage values and outputs the values to the display panel. According to the liquid crystal display device, the narrow visual angle waveform is adaptively adjusted along with the refresh rate, and the problems of waveform shaking and uneven count distribution caused by automobile allocation algorithm are solved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a liquid crystal display device and a narrow viewing angle waveform adaptive adjustment method thereof. Background technique [0002] In the prior art, the narrow viewing angle waveform usually uses a frame start signal STV (Start Vertical) as a trigger signal. If the waveform only meets the narrow viewing angle effect at a single frequency, no adaptive adjustment is required; if the waveform needs to meet the narrow viewing angle effect at multiple frequencies, the synchronization signal must be frequency adaptively adjusted along with the trigger signal. Waveform frequency adaptive adjustment can be realized by using STV trigger, but there are the following problems when using STV trigger: [0003] 1) The realization of frequency self-adaptive adjustment usually requires the method of automatic allocation of points, and the number of waveform points required for different fre...
