The invention is suitable for a liquid crystal display device and provides a liquid crystal display device with a double-gate-electrode drive architecture. The liquid crystal display device comprises a first gate electrode line, a second gate electrode line, a data line, a first pixel, a second pixel, a gate-electrode drive circuit and a source electrode drive circuit, wherein the first gate electrode line and the second gate electrode line are respectively used for transmitting a first gate electrode drive signal and a second gate electrode drive signal which are provided by the gate electrode drive circuit; the data line is used for transmitting first data and second data; the first pixel is used for displaying a picture according to the first gate electrode signal and the first data, and the second pixel is used for displaying a picture according to the second gate electrode drive signal and the second data; the source electrode drive circuit comprises a logical circuit and a multiplexer circuit; the logical circuit is used for generating an odd-even selection signal according to a scanning sequence signal and an enabling signal; and the multiplexer circuit is used for outputting one of the first data and the second data to the data line according to the odd-even selection signal. The liquid crystal display device can guarantee the correctness of data, without modifying a photomask or changing the circuit design, and can normally display images in different applications.
Description
technical field [0001] The invention relates to a liquid crystal display device, in particular to a liquid crystal display device with a double-gate driving structure. Background technique [0002] Liquid crystal display (LCD) has the advantages of low radiation, small size and low energy consumption, and has gradually replaced the traditional cathode ray tube (CRT) display, so it is widely used in notebook computers, personal Information products such as digital assistants (personaldigital assistant, PDA), flat-screen TVs, or mobile phones. The driving method of the liquid crystal display is to use a source driver circuit (source driver) and a gate driver circuit (gate driver) to drive the pixels on the panel to display images. According to different driving modes, the pixel structure of the liquid crystal display panel can be mainly divided into two types: a single-gate pixel structure and a double-gate pixel structure. At the same resolution, compared with an LCD panel ...
