Embodiment 1

[0050] This embodiment provides a wire grid polarizer and a corresponding preparation method of the wire grid polarizer. The wire grid polarizer has a wire grid structure arranged at intervals, so it can form a partial light-transmitting area, thereby controlling light more flexibly of the shot.

[0051] Such as figure 1 As shown, the wire grid polarizer includes a substrate 1, and the wire grid structure 2 arranged in an array is arranged at intervals in the substrate 1. The wire grid structure 2 allows light to pass through, and the substrate 1 except the wire grid structure 2 Other areas are continuous opaque structures.

[0052] Wherein, the thickness range of the substrate 1 is 20-250nm. Preferably, in the wire grid structure 2 , the width of the grid line is in the range of 25-250 nm, and the width of the grid pitch is in the range of 25-250 nm.

[0053]In order to ensure the strength of the wire grid polarizer and the light reflection and recycling in the opaque area...

Embodiment 2

[0071] This embodiment provides a display panel, which includes the wire grid polarizer in Embodiment 1. The display panel can effectively reduce the light absorption rate, and can also avoid light leakage around the non-sub-pixel area, and has better display effect.

[0072] Such as image 3 As shown, the display panel includes a display area 51 (Active Area, referred to as AA area) and a non-display area 52 around the periphery of the display area, that is, the display area 51 is surrounded by the inside of the non-display area 52; figure 2 The area of ​​the display panel corresponding to the display area 51 is provided with a polarizer 41 , and the polarizer 41 is a wire grid polarizer with a wire grid structure (WG for short) in Embodiment 1.

[0073] Wherein, the display area 51 includes a plurality of sub-pixel areas 53 arranged at intervals, the area of ​​the polarizer 41 corresponding to the sub-pixel area 53 has a wire grid structure, and the other area is a metal t...

Embodiment 3

[0088] This embodiment provides a display panel. Compared with Embodiment 2, the disposition position of the polarizer in the display panel is different from the disposition position of the polarizer in the display panel of Embodiment 2. The display panel can effectively reduce light absorptivity, and can also avoid light leakage around the non-sub-pixel area, and has better display effect.

[0089] In the display panel of this embodiment, the polarizer is located relatively above the array substrate. Such as Figure 4 As shown, the polarizer 41 is disposed between the TFT array 32 and the second substrate 31 , and an insulating layer 33 is disposed between the polarizer 41 and the TFT array 32 . Form a layer of insulating layer 33 above the polarizer 41, and use the insulating layer 33 to separate the polarizer 41 from the thin film transistor array 32, so as to prevent the metal forming the polarizer 41 from affecting the control function of the thin film transistor array 3...

Abstract

The invention belongs to the display technical field, and particularly relates to a wire gating polaroid, a manufacturing method of the wire gating polaroid, a display panel and a display device. The wire gating polaroid comprises a substrate, wire gating structures which are arranged in an array mode are arranged in the substrate at intervals, and due to the wire gating structures, light can penetrate from the gating distances. A continuous light-proof structure is arranged in the other area, except the wire gating structures, of the substrate. The wire gating polaroid is provided with the wire gating structures which are arranged at intervals in the array mode, hence, a local light transmitting area can be formed, and light emergence can be controlled more flexibly. By means of the display panel using the wire gating polaroid, the light absorption rate can be effectively lowered, peripheral light leakage in a non-subpixel area can further be avoided, and the pixel light leakage can be prevented; correspondingly, due to the display device using the display panel, the light utilization rate is improved, and a good display effect is achieved.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to a wire grid polarizer and a preparation method thereof, a display panel and a display device. Background technique [0002] Liquid crystal display (Liquid Crystal Display: LCD for short) is a kind of flat panel display device, and the liquid crystal display panel and the backlight source are the important components thereof. Realize image display. [0003] The liquid crystal display panel includes a color filter substrate, an array substrate, and a liquid crystal layer disposed between them, and a backlight source is disposed on a side close to the array substrate. In order to realize image display, a thin film transistor (Thin Film Transistor, referred to as TFT) is arranged in the array substrate, and the control terminal of the thin film transistor receives the control signal and the display signal respectively, and realizes the control of opening and closing of ...
