Abstract

The present invention provides a liquid crystal display panel, which includes a driving circuit, a data line, a scanning line and a pixel unit; wherein the driving circuit includes a level shifter for converting an input voltage signal into a high-level signal or a low-level signal And an output buffer for amplifying high-level signals or low-level signals; where the input of the non-inverting input and inverting input of the level shifter is determined according to the number of inverting amplifiers in the output buffer voltage signal. The invention also provides a liquid crystal display device. The liquid crystal display panel and the liquid crystal display device of the present invention can effectively reduce the production cost of the liquid crystal display panel.

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 device. Background technique [0002] With the development of technology, users' demand for high-definition large-screen display devices has increased significantly, and the market demand for liquid crystal display devices has also increased. At the same time, the technology of liquid crystal display panels is becoming more and more mature. On the basis of ensuring the quality of liquid crystal display panels, reducing the production cost of liquid crystal display panels has become a research direction that major display panel manufacturers are vying for. [0003] The driver chip of the scanning line of the traditional liquid crystal display panel outputs the scanning signal through the level shifter and the output buffer, wherein the level shifter converts the input voltage signal into a high and low level signal, ...
