Display panel, manufacturing method thereof, array substrate, and display device

Abstract

The invention discloses a display panel, a manufacturing method thereof, an array substrate and a display device and aims to achieve narrow-frame display. The display panel comprises a display area and a seal frame adhesive area. The frame seal frame adhesive area includes a first area and a second area, wherein the first area is adjacent to the display area and encloses the same, the second area is away from the display area, the second area is adjacent to the first area and encloses the same, wires connected to the voltage signal line of the display panel are disposed in the first area, heat conduction resistance bars are disposed on the wires, and the heat conduction resistance bars are used for performing thermo-curing on the seal frame adhesive in the first area.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel, a manufacturing method thereof, an array substrate, and a display device. Background technique [0002] Liquid crystal display (Liquid Crystal Display, LCD) has many advantages such as thin body, power saving, no radiation, etc., and has been widely used. At present, with the popularization of civilian products such as mobile phones and TVs, the narrow frame design of liquid crystal display devices Gradually higher requirements were raised. One of the key factors hindering the narrowing of the frame portion outside the display area of ​​the liquid crystal display device in the prior art is that the fully cured sealant cannot be cut, so a certain distance is required between the edge of the sealant and the edge of the display panel, such as figure 1 As shown, a single display panel 10 in the prior art includes a Thin Film Transistor (Thin Film Transistor...

AI Technical Summary

Problems solved by technology

One of the key factors hindering the narrowing of the frame portion outside the display area of ​​the liquid crystal display device in the prior art is that the fully cured sealant cannot be cut, so a certain distance is required between the edge of the sealant and the edge of the display panel, such as figure 1 As shown, a single display panel 10 in the prior art includes a Thin Film Transistor (Thin Film Transistor, TFT) substrate 11 and a color filter substrate 12 disposed opposite to each other, and a liquid crystal layer 13 and a sealing layer disposed between the TFT substrate 11 and the color filter substrate 12 . Frame glue 14

Due to the problem of inability to split when cutting the cured sealant in the prior art, a cutting area 15 with a certain width must be reserved between two adjacent display panels. The width of the cutting area 15 is generally 0.1 mm to 0.3 mm, the best can achieve 0.07 mm

In this way, the width of the frame area of ​​the display panel of the unit obtained after cutting in the prior art is not only the width of the sealant 14, but also partly the width of the cutting area 15, so the width of the frame of the display panel in the prior art is relatively large. , which is not conducive to the realization of narrow border display

[0003] To sum up, in the prior art, since the fully cured sealant cannot be cut, the frame of the display panel is relatively wide, which is not conducive to realizing a display with a narrow frame.
