Pixel shifting method and control method of display screen
A pixel shifting method and a control method of a display screen are provided. The pixel shifting method is adapted for the display screen, and the display screen includes at least one processor to perform the following steps. When the display screen displays a picture, pixel shifting is performed on a central point of the picture according to a shifting path. A plurality of pixels on the shifting path is allowed to be sequentially displayed on the display screen according to a plurality of different color attributes. The color attribute of each of the plurality of pixels is changed after a cycle of the pixel shifting ends.
1 . A control method of a display screen, comprising configuring at least one processor to perform steps of:
starting a timer which expires after a predetermined period;
determining whether or not the timer has reached the predetermined period;
determining whether or not the display screen receives a touch signal when the timer has reached the predetermined period; and
performing, when the display screen does not receive the touch signal and the timer has reached the predetermined period, a pixel shifting method;
wherein the pixel shifting method includes:
obtaining different brightnesses within a predetermined brightness range according to a quantity of a plurality of pixels of a shifting path;
wherein the plurality of pixels of the shifting path display different brightnesses respectively;
when the display screen displays a picture, performing pixel shifting on a central point of the picture along the shifting path;
wherein one cycle of the pixel shifting ends when the central point is shifted from a first pixel of the shifting path to a last pixel of the shifting path; and
changing the brightness of each of the plurality of pixels of the shifting path when a next cycle of the pixel shifting starts.
2 . The control method according to claim 1 , wherein the step of changing the brightness of each of the plurality of pixels comprises changing the brightness of each of the plurality of pixels to the brightness of a previous pixel of the plurality of pixels on the shifting path.
3 . The control method according to claim 1 , wherein the step of changing the brightness of each of the plurality of pixels comprises changing the brightness of each of the plurality of pixels to the brightness of a subsequent pixel of the plurality of pixels on the shifting path.
4 . The control method according to claim 1 , wherein, each of the plurality of pixels is generated by at least one organic light-emitting diode.
5 . The control method according to claim 1 , wherein the shifting path comprises a figure-eight shape, a quincunx shape, an inverse figure-eight shape, an inverse quincunx shape or a cross shape.
6 . The control method according to claim 1 , wherein the step of performing the pixel shifting on the central point of the picture comprises sequentially moving the central point of the picture along the plurality of pixels on the shifting path.
7 . The control method according to claim 1 , further comprising changing the shifting path when the timer is started again.
