TECHNICAL FIELD

Exemplary embodiments of the present application relate to display technologies, and more particularly to display screens and display devices.

BACKGROUND

With a rapid development of a mobile electronic product industry and a continuous updating of new products, a market has higher and higher expectations for mobile electronic products. For example, products such as mobile phones have a developing trend from having a frame to having a narrow frame and frameless.

SUMMARY

Accordingly, it is necessary to provide a display screen and a display device that can truly realize a full screen display.

A display screen includes: a first display region; a second display region adjacent to the first display region; and a third display region adjacent to the second display region and located on an opposite side of a side of the second display region adjacent to the first display region. A sub-pixel density of the first display region is smaller than a sub-pixel density of the second display region. The sub-pixel density of the second display region is smaller than a sub-pixel density of the third display region.

In one of the embodiments, in the first display region, a first-typed light emitting unit is formed by sharing sub-pixels. In the second display region, a second-typed light emitting unit is formed by sharing sub-pixels. In the third display region, a third-typed light emitting unit is formed by arranging sub-pixels.

In one of the embodiments, the first-typed light emitting unit is distributed in a shape of a pair of triangles with a common edge and two vertices.

In one of the embodiments, the first-typed light emitting unit includes one red sub-pixel, two green sub-pixels, and one blue sub-pixel; the red sub-pixel and the blue sub-pixel are located on the common edge, and the green sub-pixels are located at the two vertices.

In one of the embodiments, the second-typed light emitting unit is distributed in a shape of a pair of triangles with a common vertex.

In one of the embodiments, the second-typed light emitting unit includes one red sub-pixel, two green sub-pixels, and two blue sub-pixels; the red sub-pixel is located at the common vertex, and the green sub-pixels and the blue sub-pixels are located at two other vertices of each of the triangles.

In one of the embodiments, the third-typed light emitting unit is distributed in a shape of a triangle.

In one of the embodiments, the third-typed light emitting unit includes one red sub-pixel, one green sub-pixel, and one blue sub-pixel; the three sub-pixels form vertices of the triangle, respectively.

In one of the embodiments, a smallest repeating unit of the first display region includes one first pixel unit and one first blank region adjacent to the first pixel unit.

In one of the embodiments, a smallest repeating unit of the second display region includes one second pixel unit and one second blank region adjacent to the second pixel unit, or includes two second pixel units and one second blank region.

In one of the embodiments, a smallest repeating unit of the third display region comprises one third pixel unit, and does not comprise a blank region.

In one of the embodiments, the smallest repeating units of the first display region of adjacent two rows or adjacent two columns are misaligned.

In one of the embodiments, the smallest repeating units of the second display region of adjacent two rows or adjacent two columns are misaligned.

In one of the embodiments, the smallest repeating units of the third display region of adjacent two rows or adjacent two columns are misaligned.

In one of the embodiments, the third display region forms a main display region of the display screen, and the first display region forms an auxiliary display region of the display screen; the first display region is located at a side portion of the display screen, and the second display region is a transition region between the first display region and the third display region.

In one of the embodiments, a ratio of a height of the first display region to a height of the display screen is 1:10.

A display device is further provided according to the present application, which includes a display screen and an under-screen photosensitive module. The display screen includes a first display region, a second display region adjacent to the first display region, and a third display region adjacent to the second display region and located on an opposite side of a side of the second display region adjacent to the first display region. A sub-pixel density of the first display region is smaller than a sub-pixel density of the second display region. The sub-pixel density of the second display region is smaller than a sub-pixel density of the third display region. The under-screen photosensitive module is disposed under the first display region for sensing light that is incident through the display screen.

In one of the embodiments, the under-screen photosensitive module is at least one of a photoelectric sensor and a camera.

In one of the embodiments, the under-screen photosensitive module senses light that is incident through the first display region and the second display region of the display screen.

In one of the embodiments, the under-screen photosensitive module is embedded under the display screen by 4 mm to 6 mm.

The technical solution provided by the present application has at least the following beneficial effects:

By adjust the sub-pixel density of the first display region where the camera is set on the display screen, not only a normal display requirement of the first display region is met, but also a requirement that a high light transmittance needs to be maintain at the camera is met. Since there is no need to reserve a position for the front camera, the non-display region above the effective display region can be omitted, a screen occupation ratio of the display screen can be enlarged, and the use experience can be optimized, so that the technical problem that the user experience may be poor due to the presence of the non-display region can be solved.
