Problems solved by technology

[0006] Since the above-mentioned attaching process of the touch panel involves the application of OCA glue, the OCA glue application process will inevitably involve the precise control of process parameters such as the coating uniformity and coating thickness of OCA glue. This makes the attachment process of the entire touch panel relatively complicated, and at the same time cannot meet the mass production requirements of touch-type liquid crystal display panels.

Embodiment 1

[0030] This embodiment provides a polarizer, such as figure 2 As shown, it includes a polarizing film layer 1 and a first adhesive layer 2 arranged on the lower surface of the polarizing film layer 1. The first adhesive layer 2 is used for bonding with the display substrate, and also includes a polarizing film layer 1 on the upper surface The second adhesive layer 3 and the second adhesive layer 3 are used for bonding with the first film layer.

[0031] Among them, the display substrate refers to the substrate formed after the array substrate and the color filter substrate are boxed together without a polarizer attached. The first film layer is a touch film layer (ie touch panel) or a protective film layer. The protective film layer can protect the display substrate.

[0032] The arrangement of the first adhesive layer 2 and the second adhesive layer 3 enables the polarizer to be attached to the display substrate and the first film layer on both sides of the polarizer easily, the...

Embodiment 2

[0038] This embodiment provides a display panel, such as image 3 As shown, the display substrate 101 is included, and the polarizer 102 in embodiment 1 is also included. The polarizer 102 is attached to the light-emitting side of the display substrate 101, and the first polarizer 102 is attached to the side away from the display substrate 101. 膜层103。 Film layer 103.

[0039] Among them, the display substrate 101 refers to a substrate formed after the array substrate and the color filter substrate are assembled in a box without a polarizer attached. The first film layer 103 is a touch film layer (ie touch panel) or a protective film layer. The protective film layer can protect the light-emitting surface of the display substrate 101.

[0040] In this embodiment, a surface protection layer 104 is also attached to the side of the first film layer 103 away from the polarizer 102. The surface protection layer 104 can protect the first film layer 103 and prevent the first film layer 10...

Embodiment 3

[0050] This embodiment provides a display device, including the display panel in Embodiment 2.

[0051] By using the display panel in Embodiment 2, the manufacturing process of the display device is simplified, and the mass production efficiency of the display device is improved.

[0052] The display device provided by the present invention can be any product or component with a display function, such as a liquid crystal panel, a liquid crystal television, a display, a mobile phone, a navigator, and the like.

Abstract

The invention provides a polarizer, a display panel, a display panel forming method and a display device. The polarizer comprises a polarizing film layer and a first bonding layer arranged on the lower surface of the polarizing film layer. The first bonding layer is used for being bonded with a display substrate. The polarizer further comprises a second bonding layer arranged on the upper surface of the polarizing film layer. The second bonding layer is used for being bonded with a first film layer. The polarizer is formed by adding the second bonding layer to an existing polarizer, the two faces of the polarizer can be easily and conveniently attached to the display substrate and the first film layer, and therefore the attaching technology of the polarizer in the two-face attaching process is greatly simplified.

Description

Technical field [0001] The present invention relates to the field of display technology, and in particular to a polarizer, a display panel, a forming method thereof, and a display device. Background technique [0002] Liquid crystal display devices (LCD: Liquid Crystal Display) have become mainstream products in current flat panel display devices due to their small size, low power consumption, and no radiation. The liquid crystal display panel is a key component in the liquid crystal display device. [0003] In order to realize imaging and display of liquid crystal display panels, polarizers must be attached to the display panel. The main function of the polarizers is to pass light that vibrates in a specific direction. Only with polarizers whose polarization directions are perpendicular to each other can the LCD panel display images normally. [0004] At present, touch-type liquid crystal display panels have become the mainstream of market development. To enable the traditional n...
