Abstract

A display screen, a mobile terminal and a display method are provided. The display screen includes an OLED display screen and an optical fingerprint module arranged in the OLED display screen. The OLED display screen includes a light-emitting layer and a touch screen. The light-emitting layer includes a first light-emitting region and a second light-emitting region. The first light-emitting region is arranged at a position corresponding to the optical fingerprint module and configured to, when the region of the touch screen, which corresponds to the first light-emitting region, is not touched, emit light at a first preset brightness value, and when the region of the touch screen, which corresponds to the first light-emitting region, is touched, emit light at a second preset brightness value, the first preset brightness value is smaller than the second preset brightness value.

Claims (21)

1. A display screen, comprising an Organic Light-Emitting Diode (OLED) display screen and an optical fingerprint module arranged in the OLED display screen, wherein the OLED display screen comprises a light-emitting layer and a touch screen, the light-emitting layer comprises a first light-emitting region and a second light-emitting region, and the first light-emitting region is arranged at a position corresponding to the optical fingerprint module and configured to, when the region of the touch screen, which corresponds to the first light-emitting region, is not touched, emit light at a first preset brightness value, and when the region of the touch screen, which corresponds to the first light-emitting region, is touched, emit light at a second preset brightness value, the first preset brightness value is smaller than the second preset brightness value.

2. The display screen according to claim 1 , wherein the second light-emitting region is configured to, when the region of the touch screen, which corresponds to the first light-emitting region, is not touched and when the region of the touch screen, which corresponds to the first light-emitting region, is touched, emit light at the first preset brightness value.

3. The display screen according to claim 2 , wherein the first preset brightness value is greater than or equal to 600 nit.

4. The display screen according to claim 3 , wherein the second preset brightness value is 0.2 to 430 nit.

5. The display screen according to claim 4 , wherein the optical fingerprint module is arranged in the OLED display screen through an adhesive.

6. A mobile terminal, comprising the display screen according to claim 1 .

7. A display method for the mobile terminal according to claim 6 , comprising:

controlling, when it is detected that the touch screen is touched and skin patterns on the touch screen have been detected by the optical fingerprint module, the first light-emitting region to emit light at the second preset brightness value.

8. The display method according to claim 7 , wherein the controlling, when it is detected that the touch screen is touched and the skin patterns on the touch screen have been detected by the optical fingerprint module, the first light-emitting region to emit light at the second preset brightness value comprises:

controlling, when it is detected that the touch screen is touched and the skin patterns on the touch screen have been detected by the optical fingerprint module, an Emissive Layer Voltage Device Device (ELVDD) applied to the OLED display screen to be a first preset value, and an Emissive Layer Voltage Series Series (ELVSS) applied to the OLED display screen to be a second preset value; and

controlling, when the ELVDD is the first preset value and the ELVSS is the second preset value, the first light-emitting region to emit light at the second preset brightness value.

9. The display method according to claim 7 , wherein subsequent to controlling the first light-emitting region to emit light at the second preset brightness value, the display method further comprises:

controlling the second light-emitting region to emit light at the first preset brightness value.

10. A mobile terminal, comprising a memory, a processor, and a computer program stored in the memory and executed by the processor, wherein the processor is configured to execute the computer program so as to implement the display method according to claim 7 .

11. A computer-readable storage medium storing therein a computer program, wherein the computer program is executed by a processor so as to implement the steps of the display method according to claim 7 .

12. The mobile terminal according to claim 6 , wherein the second light-emitting region is configured to, when the region of the touch screen, which corresponds to the first light-emitting region, is not touched and when the region of the touch screen, which corresponds to the first light-emitting region, is touched, emit light at the first preset brightness value.

13. The mobile terminal according to claim 12 , wherein the first preset brightness value is greater than or equal to 600 nit.

14. The mobile terminal according to claim 13 , wherein the second preset brightness value is 0.2 to 430 nit.

15. The mobile terminal according to claim 14 , wherein the optical fingerprint module is arranged in the OLED display screen through an adhesive.

16. The display method according to claim 8 , wherein subsequent to controlling the first light-emitting region to emit light at the second preset brightness value, the display method further comprises:

controlling the second light-emitting region to emit light at the first preset brightness value.
