Problems solved by technology

[0003] However, OLED TV also has its own defects. Because each pixel emits light freely, when it stays in a still picture or an incomplete still picture for a long time, it will produce afterimages, commonly known as screen burn-in. If such afterimages appear Phenomenon, the screen will not be able to be repaired by compensation, in the existing technology, it is impossible to completely eliminate the residual image when the still picture

Embodiment 1

[0048] See figure 1 , figure 1 It is a flow chart of the first preferred embodiment of the method for protecting the OLED display screen of the present invention. like figure 1 Shown, a kind of protection method of OLED display screen, wherein, comprises the following steps:

[0049] Step S100, the smart TV detects the average brightness of the image on the current OLED display screen, and sets the average value of the image brightness on the current OLED display screen to be detected every preset number of frames.

[0050]In the embodiment of the present invention, after the smart TV turns on and the image appears normally, the initial value of the number of still pictures is set to n=0, and the average brightness of the current image is detected by the main chip SOC (chip and system) at the smart TV end, expressed by L1 The average brightness of the currently displayed image, after M (M is an integer between 30 and 18000) frames, detect the average brightness L2 of the cu...

Embodiment 2

[0072] The embodiment of the present invention also provides a smart TV, such as figure 2 As shown, wherein, the smart TV of this embodiment includes a processor 10, and a memory 20 connected to the processor 10;

[0073] The memory 20 stores a protection program of the OLED display screen, and the protection program of the OLED display screen is used to implement the following steps when executed by the processor 10:

[0074] The smart TV detects the average brightness of the image on the current OLED display, and sets the average value of the image brightness on the current OLED display to be detected every preset number of frames;

[0075] calculating the absolute value of the difference between the average brightness values ​​of the images detected within the period according to a preset algorithm, and judging whether the absolute value of the difference between the average brightness values ​​of the images is less than a preset brightness threshold;

[0076] When the ab...

Embodiment 3

[0090] A storage medium, wherein the storage medium stores a protection program of the OLED display screen, and when the protection program of the OLED display screen is executed by the processor 10, it is used to realize the protection method of the OLED display screen; the details are as described above.

[0091] In summary, the present invention discloses a method for protecting an OLED display screen, a smart TV and a storage medium. The method includes: the smart TV detects the average brightness value of the image in the current OLED display screen, and sets Detect the average value of the image brightness in the current OLED display screen; calculate the absolute value of the difference between the average value of the image brightness detected in the cycle according to the preset algorithm, and judge whether the absolute value of the difference between the average value of the image brightness is less than the preset value Setting a brightness threshold; when the absolu...

Abstract

The invention discloses an OLED display screen protection method, an intelligent TV and a storage medium; the method comprises the following steps: enabling the intelligent TV to detect the image brightness mean value in the current OLED display screen; using a preset algorithm to calculate the absolute value of the differences of the image brightness mean values detected in a period, and determining whether the image brightness mean value difference absolute value is smaller than a preset brightness threshold or not; if the absolute value is smaller than the preset brightness threshold and the current image is a static image, determining whether the static frequency of the current image exceeds a preset frequency or not; if yes, controlling a main chip to refresh frames of the current image. The method calculates the image brightness mean value difference absolute value in the preset period; when the current image is fully static, the main chip is controlled to refresh the frames of the playing frame, thus preventing the OLED display screen from having mura.

Description

technical field [0001] The invention relates to the technical field of smart TVs, in particular to a method for protecting an OLED display, a smart TV and a storage medium. Background technique [0002] OLED smart TV is an organic self-luminous smart TV that does not require a backlight. Compared with ordinary backlight TVs, OLED smart TVs have ultra-high contrast, high resolution, wider viewing angles, high dynamic response time, and extreme The light and thin features, therefore, have been recognized by consumers. [0003] However, OLED TV also has its own defects. Because each pixel emits light freely, when it stays in a still picture or an incomplete still picture for a long time, it will produce afterimages, commonly known as screen burn-in. If such afterimages appear Phenomenon, the screen end will not be repaired by compensation, and in the prior art, it is impossible to completely eliminate afterimages generated during still images. [0004] Therefore, the prior ar...
