Description

Double-grid panel display structure

Technical Field

The invention relates to a panel axis structure design, in particular to a routing arrangement structure of a dual-gate driving panel.

Background

For hsd (front source drive) lcd, due to its special pixel arrangement, the trace position in the panel is opaque, as shown in fig. 1, the frame part (e.g. G2 and G3 and between them) is opaque under the existing frame due to material, and it needs to occupy more area in the same layer to place G2& G3. The structure enables the pixel area of the display screen to be small, so that the aperture opening ratio of the HSD liquid crystal display screen is reduced, and the display effect of the HSD liquid crystal display screen is influenced.

Disclosure of Invention

Therefore, it is necessary to provide a new structural design of the display panel to achieve the technical effect of increasing the display area of the display screen.

To achieve the above object, the inventors provide a dual gate panel display structure in which at least one odd-numbered gate driving line and even-numbered gate driving line are overlapped in a vertical direction.

Specifically, the odd-numbered stage gate driving lines are located below the even-numbered stage gate driving lines.

Specifically, the 2 n-th gate driving line and the 2n-1 st gate driving line are overlapped in the vertical direction, and n is the number of pixel rows.

Optionally, the 2 n-th gate driving line and the 2n + 1-th gate driving line overlap in the vertical direction, where n is the number of pixel rows.

Preferably, the grid driving circuit comprises an odd-level grid driving line layer and an even-level grid driving line layer, wherein the odd-level grid driving line layer is patterned to obtain odd-level grid driving lines, and the even-level grid driving line layer is patterned to obtain even-level grid driving lines; and pixel layers are arranged between the odd-level grid driving line layer and the even-level grid driving line layer.

Different from the prior art, the grid driving wires are arranged in an overlapping mode, so that the influence of the grid driving wires on the light transmittance of the panel can be effectively reduced, and the problem of increasing the luminous efficiency of the panel is solved.

Detailed Description

To explain technical contents, structural features, and objects and effects of the technical solutions in detail, the following detailed description is given with reference to the accompanying drawings in conjunction with the embodiments.

The double-grid panel display structure is suitable for dual-grid type panel, and features that the sub-pixels in one row are driven by two grid drive lines and the two sub-pixels in adjacent rows are connected to the two grid drive lines separately. Referring to fig. 2, the dual gate panel display structure of the present invention has at least one odd-numbered gate driving line and one even-numbered gate driving line overlapped in a vertical direction. Taking the part shown in the figure as an example, for the HSD liquid crystal display screen, a layer of Metal 4 is added below Metal3, even-numbered gates are enabled to run through Metal 4, the other half of the gates run through Metal 1, the two parts of gates are parallel to each other in space, and the two gates are overlapped from top to bottom. Meanwhile, the design of other parts of the panel structure is unchanged, the source line on the panel still runs through Metal 2, and if the panel is a display panel with a touch function, the vcom line still runs through Metal 3; i.e., a total of one Metal 4 Metal and one insulating layer. Where metals 1-4 are different Metal layers in the process, the coding is not necessarily equivalent to the actual process sequence for convenience. At this time, half of the gate of the hsd (dual gate) lcd panel is driven to run through Metal 4, and when the two gate driving lines are overlapped in the vertical direction, the two gate driving lines do not occupy the area of the two parallel gate driving lines, so as to provide a larger light emitting area for the pixels, thereby improving the light emitting efficiency of the pixels.

In some embodiments, referring to fig. 2, the odd-numbered gate driving lines are located below the even-numbered gate driving lines. Similarly, when the even-numbered gate driving lines are arranged below the odd-numbered gate driving lines, the technical effects of saving the occupation of the sectional area of the panel and improving the light transmittance of the panel can be obtained.

In some embodiments as shown in fig. 3, the 2N-th gate driving line and the 2N + 1-th gate driving line are vertically overlapped, where N is 1 to N-1, and N is the number of pixel rows. In such an embodiment, G2 and G3 overlap in the vertical direction, and G4 and G5 overlap … … the first and last two gate driving lines in the vertical direction without overlapping with other gate driving lines, which is advantageous in that the wiring is easy; in other embodiments, the 2 n-th gate driving line and the 2n-1 st gate driving line are overlapped in the vertical direction, where n is the number of pixel rows. G1 and G2 can be overlapped in the vertical direction, and G3 and G4 can be overlapped in the vertical direction … …, so that all the gate driving lines can find the corresponding overlapped gate driving lines, and the design relatively increases the difficulty of the design.

In other preferred embodiments, referring to fig. 2, during the patterning process, all the odd-numbered gate driving lines are designed in the same metal layer and then patterned. All even-level grid driving lines are designed on the same metal layer and then patterned. As shown in the figure, the grid driving line structure comprises an odd-level grid driving line layer and an even-level grid driving line layer, wherein the odd-level grid driving line layer is patterned to obtain odd-level grid driving lines, and the even-level grid driving line layer is patterned to obtain even-level grid driving lines; and pixel layers are arranged between the odd-level grid driving line layer and the even-level grid driving line layer. The space structure diagram shows the relationship between each layer of Metal, Metal 4 is added in the invention, half of the gates of the HSD (dual gate) liquid crystal display screen are allowed to run through Metal 4, the other half of the gates are allowed to run through Metal 1, the upper and lower (Meatl 4 and Meatl 1) two parts of gates are parallel to each other in space, and the two gates are overlapped when viewed from top to bottom.

It should be noted that, although the above embodiments have been described herein, the invention is not limited thereto. Therefore, based on the innovative concepts of the present invention, the technical solutions of the present invention can be directly or indirectly applied to other related technical fields by making changes and modifications to the embodiments described herein, or by using equivalent structures or equivalent processes performed in the content of the present specification and the attached drawings, which are included in the scope of the present invention.
