Description

technical field [0001] The present invention relates to the field of display technology, and more particularly, to a display panel, a driving method thereof, and a display device. Background technique [0002] In the existing display device technologies, display panels are mainly divided into two mainstream technologies: liquid crystal display panels and organic self-luminous display panels. Among them, the liquid crystal display panel forms an electric field that can control the deflection of liquid crystal molecules by applying a voltage to the pixel electrodes and the common electrode, and then controls the transmission of light to realize the display function of the display panel; the organic self-luminous display panel uses organic electroluminescent materials. When a current passes through the organic electroluminescent material, the luminescent material emits light, thereby realizing the display function of the display panel. [0003] At present, the viewing angle of...

Problems solved by technology

The way to achieve narrow viewing angle in the prior art is to add a narrow viewing angle film. When the narrow viewing angle film is placed on the display panel, a narrow viewing angle is realized. When the narrow viewing angle film is removed, a wide viewing angle is realized. When this design is used very inconvenient

For LCD products, some designs set a layer of transparent electrodes on the color film substrate to control the direction of liquid crystal light leakage. This method has great influence on the entire LCD panel design, backlight design, circuit control design, and production process. Difficult, high defect rate; and because an additional electrode is added, it is very unfavorable to LCD display, resulting in poor LCD display afterimage level, light leakage at wide viewing angles, and serious brightness loss at narrow viewing angles, etc.
