Embodiment Construction

[0045] In order for those skilled in the art to better understand the technical solution of the present invention, a method and system for reducing power consumption of a display panel provided by the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0046] Embodiment 1 of the method for reducing power consumption of a display panel according to the present invention takes an OLED display panel as an example to specifically illustrate a method for reducing power consumption of a display panel.

[0047] OLED life decline is not only affected by the external environment, but also related to its own component structure and materials used. As a display, the life of OLED is also affected by device efficiency, working mode (DC, AC), driving mode, etc. . Therefore, prolonging the service life of OLED devices and improving their stability can be achieved by improving the process and materials, and by i...

Abstract

The invention discloses a method for reducing power consumption of a display panel. The method comprises the steps of: acquiring luminance of each pixel of a to-be-displayed image of the display panel; calculating average luminance of the to-be-displayed image according to the luminance of the pixels; acquiring a luminance adjusting coefficient according to the average luminance; reducing luminance of each pixel of the to-be-displayed image according to the luminance adjusting coefficient; and enhancing a contrast ratio of the pixels of the to-be-displayed image according to the luminance adjusting coefficient. The invention further discloses a system for reducing power consumption of the display panel. Through the adoption of the method, the power consumption of the display panel can be reduced, and clear display can be achieved through enhancing the contrast ratio of the displayed image.

Description

technical field [0001] The invention relates to the field of display panels, in particular to a method and system for reducing power consumption of a display panel. Background technique [0002] Display panels such as Organic Light-Emitting Diode (OLED), as a new generation of display technology, have unparalleled advantages of liquid crystal flat panel displays: active light emission, ultra-high contrast, ultra-light color gamut coverage, etc., so in the field of display status is becoming more and more important. However, the lifespan of OLED has always been an important factor restricting the development of OLED technology. The aging of OLED display panels is affected by external factors and internal factors. The internal factors are mainly due to changes in operating voltage and reduction in luminous efficiency. [0003] In order to slow down the aging speed of the OLED display panel, a common solution is to reduce the current and the brightness of the displayed image b...
