Problems solved by technology

like figure 1 As shown, in the existing liquid crystal display panel packaging structure, the sealant 200 is coated on the periphery of the display area (ActiveArea, AA) of the first substrate 100 (CF substrate or TFT substrate), and the first substrate 100 is bonded to the second substrate (TFT substrate or CF substrate) to seal the display panel, but the frame sealant 200 has a single-layer structure, and only one layer of frame sealant is required for water vapor to enter the display panel from the outside. The packaging structure cannot effectively prevent water vapor, so display defects often occur due to water vapor entering the sealant

Abstract

The invention provides a packaging structure and method of a display panel. The packaging structure comprises a first substrate (10), a second substrate (30) and frame sealing glue (20) bonding the first substrate (10) and the second substrate (30). The frame sealing glue (20) comprises a first frame sealing glue layer (21), a second frame sealing glue layer (22) and a third frame sealing glue layer (23) which are sequentially distributed from inside to outside. The first frame sealing glue layer (21) and the third frame sealing glue layer (23) are made from adhesive glue materials. The second frame sealing glue layer (22) is made from a moisture prevention material or a moisture absorption material. Therefore, the moisture prevention effect of the frame sealing glue is effectively improved under the condition that the bonding force of the frame sealing glue is ensured, and the sealing effect of the display panel is improved. According to the packaging method, packaging is conducted through the frame sealing glue of the packaging structure, and the sealing effect of the display panel is improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a packaging structure and a packaging method of a display panel. Background technique [0002] In the field of display technology, flat panel display technologies such as liquid crystal display (LCD, Liquid Crystal Display) and organic light emitting diode display (Organic Light Emitting Diode, OLED) have gradually replaced cathode ray tube display (Cathode Ray Tube, CRT). Planar light source technology is a new type of light source , its technology research and development is close to the level of mass production in the market. Among the flat panel display and planar light source technologies, the bonding of two sheets of flat glass is a very important technology, and its packaging effect will directly affect the performance of the device. [0003] Taking the liquid crystal display panel as an example, the liquid crystal display panel usually consists of a color filter (CF, Col...
