Description

Display panel and display device thereof

Technical Field

The invention relates to the technical field of display, in particular to a display panel and a display device thereof.

Background

The display device can convert the data of the computer into various characters, numbers, symbols or visual images for display, and can input commands or data into the computer by using input tools such as a keyboard, and the display contents can be added, deleted and changed at any time by means of hardware and software of the system. Display devices are classified into plasma, liquid crystal, light emitting diode, cathode ray tube, and the like, according to the display device used.

LCD (Liquid Crystal Display, English full name). The liquid crystal display uses liquid crystal material as basic component, and fills the liquid crystal material between two parallel plates, and changes the arrangement state of internal molecules of the liquid crystal material by voltage so as to attain the goal of shading light and transmitting light to display the image with different depth and error, and only adds a filter layer with three-component color between two flat plates to implement the display of color image.

Contrast is one of the important indicators for evaluating the image quality of a Liquid Crystal Display (LCD). In a real use scene, the reflectivity of the display panel may affect the contrast of the picture due to the influence of ambient light. The desire to improve the contrast of a display panel can be approached from two aspects: on one hand, the bright state brightness of the display panel is improved, and on the other hand, the reflectivity of the display panel is reduced. The reflection of the inside of the display screen to the ambient light mainly comes from the reflection of metal, including the reflection of metal in a TFT area, and the reflection of metal such as COM electrodes and storage capacitors. Therefore, a new display panel is needed to absorb the reflection of the metal, reduce the reflectivity of the display panel, and improve the contrast of the lcd.
