specific Embodiment approach

[0021] According to a specific implementation manner, the pixels on the OLED display screen include red sub-pixels, green sub-pixels and blue sub-pixels;

[0022] The parameter acquisition step includes:

[0023] It is set that when a monochrome test picture is displayed on the OLED display screen, all the sub-pixels of the same color included in the OLED display screen have the same color value;

[0024] Set the OLED display current test formula as follows:

[0025] Power_oled=Screen_Size×(Rcorf×R 2 +Gcorf×G 2 +Bcorf×B 2 -MIXcorf×(R+G+B) 2 )×BrightnessLevel+OLED_self;

[0026] Among them, Power_oled is the current consumed by the OLED display screen, Screen_Size is the number of pixels included in the OLED display screen, Rcorf is the red current coefficient, Gcorf is the green current coefficient, Bcorf is the blue current coefficient, MIXcorf is the mixed current coefficient, OLED_self is the OLED bottom electrode, R is the color value of the red sub-pixel included in...

Embodiment approach

[0112] According to a specific implementation manner, the current detection unit is specifically configured to, when a frame of picture is displayed on the OLED display screen, according to the color value of each sub-pixel included in the pixel on the OLED display screen, the OLED The pixel on the display screen includes the brightness of the sub-pixel and the calculation formula of the pixel current to obtain the current Power_pixel consumed by the pixel;

[0113] The pixel current calculation formula is as follows: Power_pixel=(Rcorf×R 2 +Gcorf×G 2 +Bcorf×B 2 -MIXcorf×(R+G+B) 2 )×BrightnessLevel;

[0114] The sum of the current consumed by all the pixels on the OLED display screen is the current consumed by the OLED display screen.

[0115] Specifically, such as Figure 5 As shown, the current detection unit 32 includes:

[0116] The sampling module 321 is connected to the OLED display screen 30, and is used to sample a frame of image on the OLED display screen 30 eve...

Abstract

The invention provides a method and device for detecting power consumption of an OLED display screen. The power consumption detection method of the OLED display screen includes: a parameter acquisition step: by displaying a monochrome test picture on the OLED display screen and detecting the current consumed by the OLED display screen at the same time, obtaining a plurality of monochrome current coefficients, and the The mixed current coefficient corresponding to the sum of the color values ​​of each sub-pixel in the pixels included in the OLED display screen, and the bottom charge of the OLED; Color value correspondence; current detection step: obtain OLED display according to the plurality of monochrome current coefficients, the mixed current coefficient, OLED bottom electricity, the color value of the sub-pixel in the pixel included in the OLED display screen, and the brightness of the OLED display screen The current consumed by the screen. The invention can accurately detect and obtain the current consumed by the OLED display screen.

Description

technical field [0001] The invention relates to the technical field of OLED display power consumption detection, in particular to a power consumption detection method and device for OLED display screens. Background technique [0002] In recent years, with the continuous development of smart phones, display screens have become an indispensable role in human-computer interaction. OLED (Organic Light Emitting Diode, Organic Light Emitting Diode) display screen has gradually replaced traditional LCD (Liquid Crystal Display, Liquid Crystal Display) due to its advantages of thinner, lighter, more sensitive, brighter, brighter, wide viewing angle, and power saving. However, the calculation technology for the power consumption of OLED displays has been stagnant, and the traditional LCD calculation method based on the brightness of the backlight is still used, which seriously affects the accuracy of the power consumption statistics of the entire system. [0003] The power consumptio...
