Description

Display panel and display device

technical field

The utility model relates to the display field, in particular to a display panel and a display device.

Background technique

Display devices have developed rapidly in the past ten years, and are widely used in modern information equipment such as televisions, computers, mobile phones, and digital cameras. Existing display devices include passive light emitting display devices, such as liquid crystal display devices (Liquid Crystal Display, LCD) and active light emitting display devices, such as organic light emitting display devices (Organic Light Emitting Display, OLED).

Wherein, the liquid crystal display device includes an array substrate and a color filter substrate arranged oppositely, pixel electrodes and thin film transistors are arranged inside the array substrate, a black matrix layer and a color resist layer are arranged inside the color filter substrate, and A liquid crystal layer is sandwiched between the array substrate and the color filter substrate, and the light transmittance of the liquid crystal molecules is controlled by each pixel electrode to form an image. In order to control the thickness of the liquid crystal layer, spacers need to be formed between the color filter substrate and the array substrate. In the prior art, there is a technical solution of dispersing silicon balls or the like as spacers in the liquid crystal layer. In recent years, in order to more accurately control the gap between the array substrate and the color filter substrate to accommodate the liquid crystal layer, support columns are formed on the color filter substrate, and spacers are formed on the array substrate. The height of the object is used to control the thickness of the cell between the array substrate and the color filter substrate.

As shown in FIG. 1 , FIG. 1 is a schematic diagram of a supporting structure of a display panel in the prior art. In a display device, a color filter substrate 11 and an array substrate 12 are included. Among them, in order to ensure the uniformity of the gap between the color filter substrate 11 and the array substrate 12, a support structure needs to be provided between the color filter substrate 11 and the array substrate 12, and the support structure includes a support provided under the color filter substrate 11. The spacer 14 arranged above the column 13 and the array substrate 12, and the color filter substrate 11 and the array substrate 12 are bonded together through the sealing glue 15, and the support column 13 and the spacer 14 are arranged opposite to each other to serve as a support box. thick effect. The size of the contact area between the support column 13 and the spacer 14 determines the size of the supporting force that can be provided. Only when the contact area between the support column 13 and the spacer 14 is sufficient, there is enough support to meet the requirements of the product. performance and quality.

Please refer to FIG. 2. FIG. 2 is a schematic diagram of the positional deviation of the support structure of the display panel in the prior art. The error produces a slight positional deviation, and the support column 13 located inside the color filter substrate 11 and the spacer 14 on the upper side of the second substrate 12 also have a relative position deviation, thus resulting in contact between the support column 13 and the spacer 14 The area is reduced, and when the display panel is squeezed, due to the reduction of the contact area between the support column 13 and the spacer 14, it cannot provide enough support to maintain the thickness of the box, resulting in poor display of the product.

Therefore, how to prevent the position deviation of the support columns and the spacers due to the position deviation of the substrate when the color filter substrate and the array substrate of the liquid crystal display device are bonded and aligned, and avoid the problem of the reduction of the contact area between the support columns and the spacers, is urgently needed. It needs to be solved by those skilled in the art.

The display panel is provided with multiple sets of support columns and pads. Since the shape and location of the support columns and pads in each unit area are similar, this figure only draws two sets of support columns in a unit area. Columns and backings are shown.

The display panel provided by Embodiment 1 of the present invention includes a first substrate 21 and a second substrate 22 which are oppositely arranged. The display panel also includes:

The support column 231 and the support column 232 arranged inside the first substrate, each support column includes a first end surface and a second end surface, the first end surface is connected to the first substrate, and the second end surface faces the The second substrate, as shown in the figure, the support column 231 includes a first end surface 2311 and a second end surface 2312, the first end surface 2311 is connected to the first substrate 21, and the second end surface 2312 faces the second Substrate 22;

Spacers 241 and spacers 242 disposed on the inner side of the second substrate 22 , the spacers 241 and spacers 242 are disposed corresponding to the supporting columns 231 and 232 respectively.

The unit supporting area is the area of the display panel that can be supported by the supporting force generated when a group of supporting columns and spacers are in full contact. In the prior art, a certain density of support columns and spacers is set according to the size of the display panel, and the area corresponding to a group of support columns and spacers is the unit support area. Because the unit support area is determined according to the support force generated when a group of support columns and the spacer are in full contact, so in the prior art, if the position deviation occurs between the first substrate and the second substrate, the support column and the spacer will It cannot be fully contacted, so the supporting force provided to the display panel is not enough, and the normal box thickness of the display panel cannot be maintained, and various defects will occur.
