Problems solved by technology

[0005] At present, the way to improve the light leakage of the display panel is mainly by adding light-shielding tape on the frame or making a black matrix on the panel, such as widening the rubber for light-shielding, using UV (Ultraviolet) glue + black matrix (BlackMatrix) , referred to as BM) and other ways to improve the shading effect, but the effect of improving L0 light leakage is not good, and it will also increase the cost of the display system and the difficulty of assembly

Embodiment 1

[0035] This embodiment provides a display panel, which can effectively alleviate the light leakage problem of the display panel by bonding a driving circuit on the side of the color filter substrate.

[0036] A display panel includes a color filter substrate, an array substrate, and a drive circuit. The color filter substrate and the array substrate are separated and overlapped, and a switching circuit pattern is provided on the side of the color filter substrate facing the array substrate. The switching circuit pattern They are respectively connected with the array substrate and the driving circuit, and the driving signal of the driving circuit is transmitted to the array substrate through the switching circuit pattern. The driving circuit here usually includes a printed circuit board or a driving chip (for example, COF, the abbreviation of Chip On Flex or Chip OnFilm, and the Chinese name is flip chip film). The display panel can solve the display panel (Panel) itself light leak...

Embodiment 2

[0049] This embodiment provides a display device, which includes the display panel in the first embodiment.

[0050] In the display device, a backlight source is arranged on one side of the array substrate. Since the display panel used has better edge shielding performance, all the light of the backlight source will be blocked by the black matrix, thereby achieving the purpose of improving light leakage. In the display panel of this embodiment, since the length of the color filter substrate is larger than that of the array substrate, and a black matrix is ​​provided on the side of the color filter substrate to directly block the light that attempts to transmit through the array substrate, it can effectively prevent the light from being transmitted through the display. panel.

[0051] Such as Figure 4 As shown, the display device adopts the above-mentioned display panel. The display panel is perfectly matched with the module frame 6 and the frame 7. Since the length of the color f...

Abstract

The invention belongs to the technical field of display and particularly relates to a display panel and a display device. The display panel comprises a color film substrate, an array substrate and a driving circuit. The color film substrate and the array substrate are separated from each other and arranged in a stacked mode. The side, facing the array substrate, of the color film substrate is provided with a switching circuit pattern, the switching circuit pattern is connected with the array substrate and the driving circuit, and a driving signal of the driving circuit is transmitted to the array substrate through the switching circuit pattern. According to the display panel, binding of the driving circuit to the color film substrate is achieved through the switching circuit pattern, and accordingly the light leakage problem of the display panel can be effectively alleviated.

Description

Technical field [0001] The invention belongs to the field of display technology, and specifically relates to a display panel and a display device. Background technique [0002] With the advancement of society and the development of technology, the representative of flat panel displays, TFT-LCD (Thin Film Transistor-Liquid Crystal Display), has become the mainstream product in the display field today, and has played an important role in industrial production and daily life. The role of this is becoming more and more popular. [0003] The TFT-LCD display panel includes a color filter substrate, an array substrate, and a liquid crystal layer disposed between the two, and is fixed by a module frame and a bezel. The display panel includes a plurality of pixels. In the array substrate, thin film transistors are formed by depositing various layers of metal and non-metal thin films and forming certain patterns, and the driving circuit applies control signals to the thin film transistors t...
