Abstract

A screen includes a substrate and a display layer located on top of the substrate. The display layer includes a primary display area and a secondary display area. A form of pixel distribution in the secondary display area differs from that in the primary display area.

Claims

1. A screen for use in user equipment (UE), comprising:

a substrate; and

a display layer located on top of the substrate,

wherein the display layer comprises a primary display area and a secondary display area, and

wherein a form of pixel distribution in the secondary display area differs from a form of pixel distribution in the primary display area.

2. The screen of claim 1,

wherein the secondary display area comprises n sub-pixel sequences, wherein each of the n sub-pixel sequences comprises at least two sub-pixels of identical color, and the n is a positive integer, and

wherein the at least two sub-pixels of identical color share one wire.

3. The screen of claim 2, wherein the n sub-pixel sequences are arranged one by one along a target direction.

4. The screen of claim 3, wherein the target direction is a vertical direction or a horizontal direction.

5. The screen of claim 3, wherein the n sub-pixel sequences comprise at least one red sub-pixel sequence, one green sub-pixel sequence, and one blue sub-pixel sequence,

wherein the at least one red sub-pixel sequence, one green sub-pixel sequence, and one blue sub-pixel sequence are arranged alternately one by one along the target direction.

6. The screen of claim 2, wherein center points of respective sub-pixels in at least one of the n sub-pixel sequences are located on one straight line.

7. The screen of claim 2, wherein all center points of respective sub-pixels in at least one of the n sub-pixel sequences are not located on one straight line.

8. The screen of claim 7, wherein an i-th sub-pixel sequence of the n sub-pixel sequences comprises a 2k-th sub-pixel with a center point located on a first straight line and a (2k−

1)-th sub-pixel with a center point located on a second straight line, the first straight line and the second straight line are parallel, i being a positive integer no greater than n, k being a positive integer, and

wherein a distance between the first straight line and the second straight line equals a distance between center points of two sub-pixels of identical color in the primary display area.

9. The screen of claim 1, wherein a sub-pixel in the secondary display area is greater in size than a sub-pixel in the primary display area.

10. The screen of claim 9, wherein the sub-pixel in the secondary display area is greater in length than the sub-pixel in the primary display area, and/or the sub-pixel in the secondary display area is greater in width than the sub-pixel in the primary display area.

11. The screen of claim 2, wherein sub-pixels of identical color in the secondary display area share one wire.

12. The screen of claim 2, wherein the secondary display area comprises at least two sub-areas, sub-pixels of identical color in each of the at least two sub-areas sharing one wire.

13. The screen of claim 1, wherein the display layer further comprises a transitional display area located between the primary display area and the secondary display area,

wherein a form of pixel distribution in the transitional display area differs from both the form of pixel distribution in the secondary display area and the form of pixel distribution in the primary display area.

14. The screen of claim 13, wherein display in the primary display area, display in the secondary display area, and display in the transitional display area are controlled separately.

15. The screen of claim 1,

wherein sub-pixels in the primary display area are arranged according to at least one of a Delta arrangement, a Pentile arrangement, or a standard Red-Green-Blue (RGB) arrangement.

16. User equipment (UE), comprising:

the screen of claim 1;

a processor; and

a memory for storing instructions executable by the processor,

wherein the processor is configured to;

send a first synchronization signal to the primary display area, and send a second synchronization signal to the secondary display area, the first synchronization signal and the second synchronization signal being for controlling simultaneous display of content by both the primary display area and the secondary display area.

17. User equipment (UE) comprising the screen of claim 1,

wherein an optical device is arranged below the secondary display area, and

wherein the optical device comprises at least one of a camera, a light sensor, a proximity sensor, an optic transmitter, or an optic receiver.

18. A method for controlling the screen of claim 1, the method comprising:

sending a first synchronization signal to the primary display area, and sending a second synchronization signal to the secondary display area, the first synchronization signal and the second synchronization signal being for controlling simultaneous display of content by both the primary display area and the secondary display area.

19. The method of claim 18, further comprising:

acquiring a raw color component of the content to be displayed in the primary display area and a raw color component of the content to be displayed in the secondary display area;

acquiring a corrected color component of the content to be displayed in the primary display area and a corrected color component of the content to be displayed in the secondary display area by performing Gamma correction respectively on the primary display area and the secondary display area;

sending the corrected color component of the content to be displayed in the primary display area to the primary display area, and sending the corrected color component of the content to be displayed in the secondary display area to the secondary display area;

determining, according to the content to be displayed in the primary display area and the secondary display area, a display parameter of a transitional display area between the primary display area and the secondary display area; and

sending the display parameter to the transitional display area for controlling display by the transitional display area according to the display parameter.

20. A non-transitory computer-readable storage medium having stored thereon a computer program that, when executed by a processor, causes the processor to perform the method of claim 18.

21. A screen structure, comprising n sub-pixel sequences, wherein the n is a positive integer,

wherein each of then sub-pixel sequences comprises at least two sub-pixels, wherein the at least two sub-pixels are of identical color, and

wherein the screen structure comprises at least two sub-pixels of identical color sharing one wire.
