Display panel

Abstract

The invention relates to a display panel, comprising a first substrate, a display layer, a second substrate and a water-proofing frame, wherein the first substrate is provided with a visual zone and a ring-shaped through trench and comprises a first base, a first metal layer, a gate-insulating layer, a second metal layer, a semiconductor layer, a bibulous insulating layer and a pixel-electrode layer; the gate-insulating layer is configured between the first and second metal layers; the second metal layer exposes part of the gate-insulating layer; the bibulous insulating layer is configured onthe second metal layer and the gate-insulating layer; the ring-shaped through trench runs through the bibulous insulating layer and the part, which is exposed by the second metal layer, of the gate-insulating layer, and surrounds the visual zone; and the water-proofing frame is configured in the ring-shaped through trench, connects the first substrate with the second substrate and encloses wet-proof space between the first substrate and the second substrate. The display panel has better reliability.

Description

technical field [0001] The invention relates to an electronic device, in particular to a display panel. Background technique [0002] Figure 1A A schematic top view of a conventional display panel is shown. Figure 1B draw Figure 1A A schematic top view of one of these pixel unit regions of the display panel. Figure 1C draw Figure 1A A schematic cross-sectional view of the display panel along the section line A-A. Figure 1D draw Figure 1B The schematic cross-sectional view of the pixel unit area along the section line B-B. It must be noted that, for the convenience of explanation, Figure 1A omitting to draw part of these components of the display panel, and Figure 1B The pixel electrodes are indicated by dotted lines. Please refer to Figure 1A , Figure 1B Figure 1C and Figure 1D As shown, the conventional electrophoretic display panel (electrophoretic display panel) 100 includes a first substrate (substrate) 110, an electrophoretic layer (electrophoresis ...

AI Technical Summary

Problems solved by technology

[0006] However, when the conventional electrophoretic display panel 100 is placed in an environment with moisture, the moisture-absorbing flat layer 114 with a small thickness will still absorb moisture in the external environment, so that the external moisture enters the electrophoretic display panel 100 Visible area V1 of the first substrate 110

Therefore, the switching elements 112c in the visible area V1 and the electrophoretic layer 120 corresponding to the visible area V1 are easily damaged due to the entry of external moisture, thereby reducing the reliability of the electrophoretic display panel 100.

[0007] It can be seen that the above-mentioned existing display panel obviously still has inconvenience and defects in structure and use, and needs to be further improved urgently.

In order to solve the above-mentioned problems, the relevant manufacturers have tried their best to find a solution, but for a long time no suitable design has been developed, and the general product has no suitable structure to solve the above-mentioned problems. This is obviously the relevant industry. Urgent problem
