Liquid crystal display panel and liquid crystal display

Abstract

The invention discloses a liquid crystal display panel and a liquid crystal display. The liquid crystal display panel comprises a plurality of data wires, a plurality of scanning lines and a plurality of pixels; the pixels comprise a first pixel and a second pixel; and both the first pixel and the second pixel comprise pixel electrodes. A switching element is electrically connected with the firstpixel and the second pixel to form regional pixels so that the first pixel and the second pixel with opposite polarities in each regional pixel can pre-charge each other in the previous scanning timeby using self stored charges with different polarities, and a pre-charge circuit is free from being additionally increased in the liquid crystal display panel to realize pre-charge of the pixels; therefore, the electric energy consumption and the production and manufacturing cost are reduced, and the working stability of the liquid crystal display panel is improved. Moreover, because the timing sequence redesign for scanning signals is not needed, the production and manufacturing cost is further reduced, and the generality of the proposal is improved.

Description

technical field [0001] The invention relates to the field of liquid crystal display, in particular to a liquid crystal display panel and a liquid crystal display with improved pixel charging characteristics. Background technique [0002] Liquid crystal displays (LCDs) are widely used in various electronic products, such as mobile phones, personal digital assistants (PDAs) and notebook computers, due to their advantages of thinness, lightness, power saving, and no radiation. With the development of liquid crystal display technology and the appearance of large-size flat-panel liquid crystal displays, liquid crystal displays have gradually replaced cathode ray tube (CRT) televisions in the field of traditional televisions and gradually become the mainstream of thin flat-screen televisions. [0003] Currently, LCDs are gradually developing towards large size, high resolution (High Resolution) and high refresh rate (High Frequency). The pixel structure arrangement of the current...

But at the same time, it is easy to find that the energy for precharging the pixels needs to be input from the outside through the scanning line, so that an additional precharging circuit needs to be added in the LCD panel, which not only increases the processing and manufacturing cost of the LCD panel, but also increases the precharging circuit. It will also bring about the improvement of energy consumption and further increase the heat generation of the circuit, thereby reducing the working stability of the liquid crystal display panel; in addition, since the above-mentioned precharging methods are all realized by scanning lines, the scanning lines are In addition to providing the scanning voltage signal for the pixel, it is also necessary to meet the signal requirements for pre-charging the corresponding pixel power supply. Therefore, the liquid crystal display must be equipped with a complex driving circuit to meet the requirements of display quality and response time. Therefore, when making the liquid crystal display require higher cost
