Description

Technical Field

[0001] The utility model relates to the technical field of display screens, and in particular to a touch display screen. Background Art

[0002] Display devices have been widely used, but the shapes of existing display screens are becoming more and more diverse, such as the notch screen and water drop screen in the full screen that pursues screen-to-body ratio. The development idea of ​​this type of display screen is to dig a hole in the screen to place the front camera and hide the camera module in the panel, and the in-plane hole technology came into being. It will enlarge the effective display area and increase the screen-to-body ratio of the display screen. For example, the blind hole screen that pursues function sacrifices part of the screen-to-body ratio in order to make a certain performance stronger.

[0003] In recent years, display screens with rounded corners have won the favor of consumers. However, in the process of connecting the touch blocks and touch traces, the display screens with rounded corners have the problem of too few connecting vias. On the one hand, too few vias increase the RC loading between the touch blocks and the touch IC, resulting in insensitive touch or touch failure; on the other hand, due to too few vias, process fluctuations may make it impossible for the touch blocks to be effectively connected to the touch traces, making it impossible for the touch blocks to be effectively controlled by the touch IC, which may reduce the display touch quality. Summary of the invention

[0055] In the existing special-shaped display screen 100 with rounded corners, the number of connecting vias 130 in the special-shaped area is too small, which reduces the display quality.

[0056] To solve the above problems, a touch display screen 100 is proposed.

[0057] A touch display screen 100 includes a plurality of first touch blocks 110 and a plurality of touch traces; the touch traces are connected to the first touch blocks 110 through a plurality of vias 130; wherein, a second touch block 120 is also included; the second touch block 120 is an irregular touch block, and at least one touch trace is led out from an arc-shaped edge of the second touch block 120 and turns back to be connected to the second touch block 120 through the via 130 for a second time.

[0058] The AA display area of ​​the touch display screen 100 is composed of a first touch block 110 in the middle with a regular square shape and a second touch block 120 with irregular rounded corners.

[0059] The second touch block 120 with rounded corners is symmetrical in both vertical and horizontal directions.

[0060] The touch display screen 100 has a plurality of touch wirings forming a wiring array, which are connected to the first touch block 110 and the second touch block 120 in the AA display area through the via 130 .

[0061] The outer touch connection line is connected to the first touch block 110 and the second touch blocks 120 at the upper and lower ends through the via hole 130 .

[0062] Preferably, the touch wiring is connected to the first touch block 110 through n vias 130. Each touch wiring is connected to the first touch block 110 through a set number of vias 130.

[0063] Furthermore, the touch wiring includes a first touch connection line 140 ; ​​the first touch connection line 140 is disposed at the outermost side of the touch wiring array; the first touch connection line 140 includes a first connection portion 141 and a second connection portion 142 .

[0064] The first connection portion 141 is used for the first connection with the second touch block 120 through the via 130, and the number of vias 130 connected to the second touch block 120 is m; the second connection portion 142 is used for the second connection with the second touch block 120 through the via 130, and the number of vias 130 connected to the second touch block 120 is n.

[0065] From outside to inside, the number of vias 130 of the first touch connection line 140 and the second touch connection line 150 and the irregular second touch blocks 120 at both ends gradually increases. However, due to the irregular shape, the number of vias 130 connected to the first touch block 110 cannot be reached.

[0066] The first touch connection line 140 can be connected to the second touch blocks 120 at both ends through one via 130, and the second touch connection line 150 can be connected to the second touch blocks 120 at both ends through two vias 130. The number of vias 130 is too small, such as Figure 1 , Figure 1 The via connection diagram of the touch display screen in the prior art affects the touch effect and also reduces the display quality.

[0067] like Figure 2 , Figure 2 Schematic diagram of the via connection of the touch display screen in the present invention. In this embodiment, the AA display area is extended from the first connection part 141 through the second connection part 142, and then rotated to the second touch block 120 for secondary connection, which increases the number of connections of the touch wiring of the special-shaped touch block, reduces the risk of failure of the via 130, and improves the touch display quality. There are four special-shaped second touch blocks 120, which are symmetrically located at the four corners of the touch display screen 100.

[0068] Furthermore, the first touch connection line 140 also includes a third connection portion (not shown in the figure) and a fourth connection portion. The third connection portion (not shown in the figure) is used to make a first connection with the symmetrical second touch block 120 through the via 130, and the number of vias 130 is m; the fourth connection portion is used to make a second connection with the symmetrical second touch block 120 through the via 130, and the number of vias 130 is n.

[0069] The symmetrical second touch block 120 is a special-shaped touch block located at the bottom of the mobile phone. It is symmetrical with the special-shaped touch block at the top, and the number of vias 130 for the primary connection and the secondary connection is the same.

[0070] Furthermore, the touch wiring also includes a second touch connection line 150; the second touch connection line 150 is configured to be adjacent to the first touch connection line 140; the second touch connection line 150 includes a fifth connection portion and a sixth connection portion, the fifth connection portion is used to make a first connection with the second touch block 120 through the via 130, and the number of vias 130 is m+1; the sixth connection portion is used to make a second connection with the second touch block 120 through the via 130, and the number of vias 130 is n.

[0071] Furthermore, the second touch connection line 150 includes a seventh connection portion and an eighth connection portion; the seventh connection portion is used to make a primary connection with the symmetrical second touch block 120 through the via 130, and the number of vias 130 is m+1; the eighth connection portion is used to make a secondary connection with the symmetrical second touch block 120 through the via 130, and the number of vias 130 is n.

[0072] The second touch connection line 150 is adjacent to the first touch connection line 140 , and the number of vias 130 connected to the second touch block 120 increases slightly, but still needs to be turned around for secondary connection until the number of vias 130 is the same as the number of vias 130 connected to the first touch block 110 .

[0073] Preferably, the number n of vias 130 connecting the touch trace and the first touch block 110 is 5, and the number m of vias 130 connecting the first connection portion 141 and the third connection portion (not shown) and the second touch block 120 is 1.

[0074] The touch display screen 100 of the present invention extends the touch wiring of the special-shaped touch block outside the AA display area and turns around to make a secondary connection with the special-shaped touch block, thereby increasing the number of connections of the touch wiring of the special-shaped touch block, reducing the risk of failure of the via 130, and improving the touch display quality.

[0075] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
