Embodiment Construction

[0047] In the prior art, AMOLED-based wearable display devices adopt a fixed screen refresh rate and an independent power supply mode, see figure 1 . Such as figure 1 As shown, the display panel is powered by an independent power supply. The display panel is an AMOLED panel. The independent power supply provides two supply voltages, one is positive voltage ELVDD, and the other is negative voltage ELVSS. The display panel is in high power consumption mode and low power consumption mode. The power supply voltage is provided by an independent power supply.

[0048] In addition, the screen refresh frequency f1 of the display panel in the high power consumption mode and the screen refresh frequency f2 of the display panel in the low power consumption mode are both fixed values. The screen refresh rate should be at least 15HZ. The screen refresh frequency in different modes is burned in the drive circuit through OTP, and burned in the drive circuit through a dynamic password (One...

Abstract

The invention discloses a display device and a screen power dissipation control method thereof. The method comprises the steps that a drive circuit obtains and stores current frame signals, accordingto the current frame signals, it is determined that the display panel displays the display current supplied by the current frame, and display current is fed back to a power selection module; the powerselection module receives the display current fed back by the drive circuit, and when it is determined that the drive circuit can supply the display current, a power supply source of the display panel is determined as the drive circuit. When the display panel is in the low power dissipation mode, when it is determined that the drive circuit meets the power supply requirement of the display panel,the power supply selection module enables the drive circuit to supply power to the display panel, and compared with the prior art that an independent power source is adopted for supplying power to the display panel, the total power dissipation of a screen of the display panel can be lowered under the same outside condition.

Description

technical field [0001] The present application relates to the technical field of wireless communication, and in particular to a display device and a method for controlling power consumption of the screen. Background technique [0002] Active-matrix organic light emitting diode (AMOLED for short) display panel is a material mainly composed of organic semiconductors and light-emitting materials driven by an electric field through carrier injection and recombination. panel. Compared with traditional LCD, AMOLED display panel has the advantages of fast response, wide color gamut, high contrast, self-illumination and lower power consumption. [0003] With the rapid development of AMOLED technology, there are more and more types of wearable products, larger display ratio, lighter and thinner design will be the direction of future development, limited by the slow development of battery technology, reducing the display performance Power consumption will be a big challenge, and goo...
