Problems solved by technology

If the number of data lines is reduced, each data line spans relatively more scan lines, resulting in a larger RC delay, and at the same time, its corresponding maximum effective charging time is shorter, making it difficult for the corresponding sub-pixels to charge to the correct potential , resulting in poor display effect of the liquid crystal display device

Abstract

The invention discloses a liquid crystal display device and a driving method thereof. The liquid crystal display device comprises a liquid crystal display panel, gate drivers and source drivers, wherein the liquid crystal display panel is provided with 2m scanning lines along the direction of a long shaft of a substrate and n / 2 data lines along the direction of a short shaft of the substrate; the 2m scanning lines and the n / 2 data lines define m columns and n rows of sub-pixels; a (2k-1)th scanning line and a (2k)th scanning line are connected with a k-th column of sub-pixels alternately, k is more than or equal to 1 and less than or equal to m, and m and k are natural numbers; and a g-th data line is connected with a (2g-1)th row of sub-pixels and a (2g)th row of sub-pixels, g is more than or equal to 1 and less than or equal to n / 2, n and g are natural numbers, and n is a multiple of 2. By the liquid crystal display device and the driving method thereof, the number of the source drivers can be reduced, the manufacturing cost of the liquid crystal display device is reduced, and the sub-pixels can be sufficiently charged to have correct potential.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a liquid crystal display device and a driving method thereof. Background technique [0002] With the rapid development of liquid crystal display technology, liquid crystal displays have been widely used in various electronic devices, such as mobile phones, personal digital assistants, digital cameras, computer screens and so on. [0003] Most of the current liquid crystal displays use many data lines, which require more source driver chips to control, but the cost of the source driver chips is high. [0004] Some LCD manufacturers reduce the data lines to 1 / 3 or 1 / 2 in order to reduce the manufacturing cost of LCDs. If the number of data lines is reduced, each data line spans relatively more scan lines, resulting in a larger RC delay, and at the same time, its corresponding maximum effective charging time is shorter, making it difficult for the corresponding sub-p...
