Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. The following description refers to the accompanying drawings in which the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

As shown in fig. 1 to 3, the present disclosure provides a display screen 1, the display screen 1 being used for a terminal device to display an image. The terminal device includes but is not limited to electronic devices such as mobile phones, notebook computers and tablet computers, and is particularly suitable for an off-screen camera device without punching. In order to display an image, the display screen 1 has a plurality of pixels capable of being lit, and the common pixels are in RGB pixel format, that is, different images are obtained by changing three color channels of red (R), green (G), and blue (B) and superimposing the three color channels on each other.

Fig. 3 is a schematic diagram showing a distribution of pixel points of a display screen according to the related art, in which pixel points of different color channels are exemplarily represented in different patterns. In order to realize touch operation of the terminal device, a touch wiring 14(Trace Line) is arranged on the screen body, and the terminal device is operated in a touch manner through the touch wiring 14, such as capacitive touch. Since the off-screen display technology has an advantage that no hole needs to be formed in the screen body, in order to improve transmittance and achieve a better shooting effect, the touch wiring 14 at a position (UDC display area, dotted circle position in fig. 3) of the screen body corresponding to the optical device needs to be removed. Because the touch wiring 14 does not shield light, the light transmittance is improved, and meanwhile, the brightness of the UDC display area is brighter than that of a normal area (other positions except the UDC area), especially the position close to the UDC display area, and the difference of the brightness is more obvious under a large visual angle, so that the use experience is influenced.

To solve this problem, as shown in fig. 2, the present disclosure designs a display screen 1 to include a main display area 12 having a plurality of pixels, a sub display area 11, and a transition display area 13. The transition display area 13 surrounds the sub display area 11, and the main display area 12 surrounds the transition display area 13. The display screen 1 further includes a plurality of touch wirings 14 disposed adjacent to the pixel points, and a line width of the touch wirings 14 is gradually increased from an outer edge of the sub display region 11 to an inner edge of the main display region 12.

In detail, the sub display area 11 is used to cover the optical device 21, or the UDC display area is disposed at a position corresponding to the position of the optical device 21 after the terminal device is assembled. The touch wiring 14 at the position of the sub display area 11 is removed to improve light transmittance. The transition display region 13 surrounds the sub display region 11, and the main display region 12 surrounds the transition display region 13, that is, the transition display region 13 is disposed between the main display region 12 and the sub display region 11, whereby the present disclosure changes the two-region design widely adopted in the related art into the three-region design by disposing the transition display region 13. The transitional display area 13 can be regarded as a brightness buffer area, the amount of light rays which can be shielded by the transitional display area is changed along with the change of the line width of the touch control wiring 14, and the display difference between the main display area 12 and the auxiliary display area 11 is weakened due to the fact that the brightness sensitivity of human eyes to gradual change is relatively weak.

It should be added that, because the touch wires 14 are routed along the channels between the adjacent pixels, not all the touch wires 14 are located inside the transitional display area 13, and at least one touch wire 14 located at the outer edge of the sub display area 11 and one touch wire 14 located at the inner edge of the main display area 12 are located between two adjacent display areas.

The technical scheme provided by the embodiment of the disclosure can have the following beneficial effects: by arranging the transition display area 13 between the main display area 12 and the auxiliary display area 11, the design of two areas in the related art is changed into a three-area design, the line width of the touch wiring 14 is gradually increased from the outer edge of the auxiliary display area 11 to the inner edge of the main display area 12, the display boundary between the main display area 12 and the auxiliary display area 11 under a large visual angle is weakened, the brightness change from the auxiliary display area 11 to the main display area 12 is more uniform, and the display effect is improved.

According to an embodiment of the present disclosure, the line widths of the plurality of touch routing lines 14 may vary linearly, and the distance between any two adjacent touch routing lines 14 is equal. For example, the line width of the first touch wiring 14 on the outer edge of the sub display region 11 is designed to be 1 μm, and the line width increases by 0.5 μm every N pixels (shown in fig. 2 as 1 pixel) from the sub display region 11 to the main display region 12. This design makes the arrangement of the touch wiring 14 more uniform, that is, the change of the brightness of the transitional display area 13 is also more uniform, further improving the display difference.

The touch wiring 14 disposed at the inner peripheral edge of the main display area 12 has the same line width as the touch wiring 14 disposed at the main display area 12. The main display area 12 is mainly used for displaying images and touch operations, generally, the plurality of touch wirings 14 in the main display area 12 have the same line width, and the line width of the touch wirings 14 in the transitional display area 13 of the present disclosure is gradually increased until the line width is equal to that of the touch wirings 14 in the main display area 12, so that the brightness of the outer edge of the transitional display area 13 is closer to that of the main display area 12, and the transition of the brightness is more natural.

As shown in fig. 2, a plurality of pixels may be distributed in a rectangular array, which is more convenient in design and manufacture compared with other layout manners, such as a circular array, so as to improve the production efficiency. Of course, to meet different requirements, the pixels may be arranged in other forms, such as a circular array, and the object of the present invention can be achieved by only controlling the line width of the touch wiring 14 to gradually change from the outer edge of the sub display region 11 to the inner edge of the main display region 12.

The main display area 12, the transition display area 13, and the sub display area 11 may have the same pixel density. Since the purpose of weakening the display difference is achieved by gradually changing the line width of the touch wiring 14, the pixel densities of the main display area 12, the transition display area 13 and the sub display area 11 do not need to be adjusted, and the pixel densities of all the display areas are designed to be the same, which is also beneficial to improving the design and manufacturing efficiency. In the related art, there is a scheme for improving the display difference by changing the pixel density, and the design of the scheme is complicated. Of course, in the case where the main display area 12, the transition display area 13, and the sub display area 11 are designed to have different pixel densities, the object of the invention can also be achieved by gradually changing the line width of the touch wiring 14.

According to an embodiment of the present disclosure, with continued reference to fig. 2, the plurality of touch routing wires 14 are distributed in a zigzag shape from the outer edge of the sub display area 11 to the inner edge of the main display area 12. The design of the shape of the Chinese character hui is more beneficial to realizing gradual change of the line width of the touch control wiring 14. In other words, if the touch wiring 14 of the transitional display area 13 is distributed like the main display area 13 in a # -shape, it is obviously more difficult to realize gradual change of the line width due to the staggered lines, which easily causes uneven distribution of the line width and affects the display effect. The touch wiring 14 in the main display area 12 can still adopt the # -shaped distribution due to the same line width, and at this time, the # -shaped distribution can improve the distribution density, thereby improving the sensitivity of the touch operation.

For those skilled in the art, with a limited number of attempts, the setting parameters of the plurality of touch control wirings 14, including but not limited to linear variation, number, and spacing, can be adjusted, so that the luminance difference of any two of the main display area 12, the transitional display area 12, and the auxiliary display area 11 at the same gray scale level is within ± 20%, and the chrominance difference is within ± 2 JNCD.

A second object of the present disclosure is to provide a terminal device, as shown in fig. 1, which includes a display screen 1 and an optical device 21, wherein the optical device 21 is disposed on the terminal body 1, and the display screen is the display screen of any one of the above items, and has all the advantages of the display screens. Alternatively, the optical device may be at least one of a camera, an optical sensor, an optical transmitter, or an optical receiver. In addition, because the UDC display technology is adopted, holes do not need to be formed in the screen body, and therefore the whole display screen 1 can be fully paved with a plurality of pixel points, and the comprehensive screen display effect is achieved.

Other embodiments of the disclosure will be apparent to those skilled in the art from consideration of the specification and practice of the disclosure. This application is intended to cover any variations, uses, or adaptations of the disclosure following, in general, the principles of the disclosure and including such departures from the present disclosure as come within known or customary practice within the art to which the disclosure pertains. It is intended that the specification and examples be considered as exemplary only, with a true scope and spirit of the disclosure being indicated by the following claims.

The scope of the present disclosure is limited only by the appended claims.
