Abstract

An embodiment of the invention provides a display panel and a preparation method thereof and a display device. The display panel comprises an array substrate and a color film substrate, lower electrodes and upper slit electrodes are arranged on the array substrate, additional electrodes are arranged on the color film substrate and positioned above gaps of the upper slit electrodes, and the additional electrodes and the upper slit electrodes form additive electric fields for driving liquid crystal near the color film substrate to eccentrically rotate. Same transmittance, response time and viewing angles are achieved, driving voltage of the display panel is 80% that of an existing display panel, driving voltage is effectively reduced, the driving voltage of the display panel is reduced, power consumption of the display panel can be reduced, and use reliability of GOA circuits and related chips is improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display panel, a manufacturing method thereof, and a display device. Background technique [0002] Thin Film Transistor-Liquid Crystal Display (TFT-LCD) has the characteristics of small size, low power consumption, and no radiation. It has developed rapidly in recent years and occupies a dominant position in the current flat panel display market. The main structure of TFT-LCD is a liquid crystal display panel. The liquid crystal display panel includes a thin film transistor array (Thin Film Transistor, TFT) substrate and a color filter (Color Filter, CF) substrate, and liquid crystal (Liquid Crystal, LC) molecules are filled in the array. Between the substrate and the color filter substrate, an electric field for driving liquid crystal deflection is formed by controlling the common electrode and the pixel electrode to realize grayscale display. [0003] At present, TFT-LCD ca...
