Description
Technical Field

Background
The OLED screen belongs to a self-luminous screen and is displayed by red light, green light and blue light respectively emitted by a red sub-pixel, a green sub-pixel and a blue sub-pixel.
However, since the half-lives of the sub-pixels with different colors are different, in general, the life of the green sub-pixel G is longest, the life of the red sub-pixel R is second, and the life of the blue sub-pixel B is shortest, so that after the OLED screen is used for a long time, the blue sub-pixel B is firstly aged, thereby causing phenomena such as color cast on the OLED screen, and affecting the display effect of the whole OLED screen. Moreover, if the OLED screen shown in fig. 1 is frozen on the same screen for a long time, there is a high possibility that the blue sub-pixel B area no longer displays blue light, but instead presents a black line, which easily causes the phenomena of afterimage and screen burn on the OLED screen, and reduces the service life of the OLED screen.

Detailed Description
In order to make the technical solutions of the present invention better understood, the present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Unless defined otherwise, technical or scientific terms used herein shall have the ordinary meaning as understood by one of ordinary skill in the art to which this invention belongs. The use of "first," "second," and similar terms in the present application do not denote any order, quantity, or importance, but rather the terms are used to distinguish one element from another. The word "comprising" or "comprises", and the like, means that the element or item listed before the word covers the element or item listed after the word and its equivalents, but does not exclude other elements or items.
In this embodiment, the red sub-pixel R, the green sub-pixel G, the first blue sub-pixel B1, and the second blue sub-pixel B2 are all organic electroluminescent diodes as an example.
Example 1:
the present embodiment provides a display method of a display panel, where the display panel includes a plurality of pixels, and each pixel at least includes: a red subpixel R, a green subpixel G, a first blue subpixel B1, and a second blue subpixel B2. The display method of the embodiment mainly divides the blue sub-pixel B into a first blue sub-pixel B1 and a second blue sub-pixel B2, and controls the first blue sub-pixel B1 and the second blue sub-pixel B2 to alternately or simultaneously display blue light according to the attenuation of the two sub-pixels, so as to achieve the effects of improving the display effect of the display panel and prolonging the service life of the display panel.
Specifically, as shown in fig. 2, the display method provided in this embodiment specifically includes the following steps:
s1, periodically detecting the attenuation degree of the first blue sub-pixel B1 and the second blue sub-pixel B2 in the display panel.
Wherein, the step S1 specifically includes:
s11, the chrominance values of the first blue sub-pixel B1 and the second blue sub-pixel B2 are periodically obtained.
Specifically, each time the first blue sub-pixel B1 and the second blue sub-pixel B2 operate for a period of time, the first blue sub-pixel B1 and the second blue sub-pixel B2 need to be simultaneously lighted up to obtain the chromaticity values of the first blue sub-pixel B1 and the second blue sub-pixel B2. The period of time here may be one week, one month, etc., and it may be specifically set according to actual situations, and is not limited herein.
And S12, judging and obtaining the attenuation degree of the first blue sub-pixel B1 and the second blue sub-pixel B2 according to the chromaticity values of the first blue sub-pixel B1 and the second blue sub-pixel B2.
That is, the present embodiment calculates the degrees of attenuation of the first blue subpixel B1 and the second blue subpixel B2 according to the chromaticity values of the first blue subpixel B1 and the second blue subpixel B2 acquired in step S11.
S2, judging whether the attenuation degree of the first blue sub-pixel B1 and the second blue sub-pixel B2 is smaller than a preset value.
In this embodiment, when the chromaticity values of the first blue subpixel B1 and the second blue subpixel B2 are half of the initial chromaticity values of the two subpixels, the calculated attenuation value is the preset value of this embodiment. Of course, in this embodiment, when the chromaticity values of the first blue subpixel B1 and the second blue subpixel B2 are one third (or one fourth, etc.) of the initial chromaticity value, the calculated attenuation value may be a preset value, which is not limited herein.
Wherein, the initial chromaticity value here refers to: the chromaticity values of the first blue sub-pixel B1 and the second blue sub-pixel B2 when the first blue sub-pixel B1 and the second blue sub-pixel B2 are never used, that is, when both are produced from the factory. At this time, it is easily understood that the maximum chromaticity values of the first blue sub-pixel B1 and the second blue sub-pixel B2 are the initial chromaticity values, and as the operating time of the first blue sub-pixel B1 and the second blue sub-pixel B2 increases, the chromaticity values of the first blue sub-pixel B1 and the second blue sub-pixel B2 have smaller chromaticity values and larger attenuation degrees.
Specifically, if the attenuation of the first blue sub-pixel B1 and the attenuation of the second blue sub-pixel B2 calculated in step S12 are smaller than the preset value, it is predicted that the display effect of the display panel can be ensured by only using the first blue sub-pixel B1 or the second blue sub-pixel B2 to display blue light, and at this time, step S3 is performed.
If the attenuation degrees of the first blue sub-pixel B1 and the second blue sub-pixel B2 calculated in step S12 are greater than or equal to the predetermined value, it indicates that the working time of the first blue sub-pixel B1 and the second blue sub-pixel B2 is longer, and both of them are aged, and at this time, if a single first blue sub-pixel B1 or a single second blue sub-pixel B2 is still used to display blue light, the display effect achieved by the first blue sub-pixel B1 and the second blue sub-pixel B2 will not meet the normal display effect of the display panel. Therefore, to avoid color shift of the display panel, the first blue sub-pixel B1 and the second blue sub-pixel B2 are controlled to be turned on simultaneously for displaying, that is, step S4 is performed.
And S3, controlling the first blue sub-pixel B1 and the second blue sub-pixel B2 to be displayed in a switching way after the preset frame picture is displayed.
Specifically, when it is determined in step S2 that the attenuation of the first blue sub-pixel B1 and the attenuation of the second blue sub-pixel B2 are smaller than the predetermined value, the first blue sub-pixel B1 and the second blue sub-pixel B2 are controlled to alternately display two adjacent frame pictures.
That is, after each frame of picture is displayed on the display panel, the blue sub-pixel displaying the current frame of picture is switched to another blue sub-pixel. For example: if the current frame is displayed by the first blue sub-pixel B1, the next frame is displayed by the second blue sub-pixel B2. Of course, the preset frame picture here may also be a five-frame picture, a ten-frame picture, and the like, and is not limited herein.
S4, controlling the first blue sub-pixel B1 and the second blue sub-pixel B2 to be displayed simultaneously in each frame.
Specifically, if it is determined in step S2 that the attenuation of the first blue sub-pixel B1 and the attenuation of the second blue sub-pixel B2 are greater than or equal to the predetermined value, the first blue sub-pixel B1 and the second blue sub-pixel B2 are controlled to display simultaneously.
In summary, if the period in which the attenuation of the first blue sub-pixel B1 and the second blue sub-pixel B2 is less than the predetermined value is divided into the early stage using the first blue sub-pixel B1 and the second blue sub-pixel B2 according to the variation of the attenuation of the first blue sub-pixel B1 and the second blue sub-pixel B2; dividing the period in which the attenuation degrees of the first blue sub-pixel B1 and the second blue sub-pixel B2 are greater than or equal to the predetermined value into the later stage using the first blue sub-pixel B1 and the second blue sub-pixel B2, according to the display method provided above, in the early stage, steps S1, S2, and S3 are repeatedly executed, and when the attenuation degrees of the first blue sub-pixel B1 and the second blue sub-pixel B2 are equal to the predetermined value, the later stage is entered, that is, step S4 is repeatedly executed until the display effect of the display panel cannot be satisfied even if the first blue sub-pixel B1 and the second blue sub-pixel B2 emit light simultaneously. It can thus be seen that: compared with the service life of the blue sub-pixel B in the prior art, the service life of the blue sub-pixel B composed of the first blue sub-pixel B1 and the second blue sub-pixel B2 in the present embodiment is at least doubled, and thus, the service life of the display panel including the blue sub-pixel B is also prolonged.
So far, the display of the whole display panel is completed.
In order to further improve the display effect of the display panel that performs display by using the display method provided in this embodiment, the following describes the arrangement of the sub-pixels in the display panel in this embodiment.
Preferably, as shown in fig. 3, in each column of pixels of the display panel, the first blue sub-pixel B1 in any two adjacent rows is located in a different sub-pixel column, and the second blue sub-pixel B2 in any two adjacent rows is located in a different sub-pixel column. This kind of structural arrangement can avoid the sub-pixel of a certain row to be first blue sub-pixel B1 or second blue sub-pixel B2 entirely, so, when all first blue sub-pixels B1 are put out, the second blue sub-pixel B2 that is located the same row with first blue sub-pixel B1 will show blue light to avoided in the prior art, the regional blue sub-pixel B no longer shows blue light and presented the condition of a black line, also avoided the display panel to appear phenomenons such as colour cast, ghost, burn-in, improved the display effect of the display panel in this embodiment.
Similarly, when all the second blue sub-pixels B2 are turned off, the first blue sub-pixel B1 in the same column as the second blue sub-pixel B2 can also display blue light, which can also prevent the display panel from color cast, image sticking, screen burn, and the like.
Further preferably, as shown in fig. 3, every two adjacent pixels in the same column form a repeating unit, one pixel in each repeating unit includes a red sub-pixel R, a green sub-pixel G, a first blue sub-pixel B1 and a second blue sub-pixel B2, which are sequentially arranged along the row direction, and the other pixel includes a green sub-pixel G, a first blue sub-pixel B1, a second blue sub-pixel B2 and a red sub-pixel R, which are sequentially arranged along the row direction.
Of course, one pixel in each repeating unit may also include a red sub-pixel R, a first blue sub-pixel B1, a second blue sub-pixel B2, and a green sub-pixel G sequentially arranged along the row direction, and another pixel includes a first blue sub-pixel B1, a second blue sub-pixel B2, a red sub-pixel R, and a green sub-pixel G sequentially arranged along the row direction, and so on, as long as two first blue sub-pixels B1 in each repeating unit are arranged in an interlaced manner, and two second blue sub-pixels B2 are arranged in an interlaced manner, which is not listed here.
In summary, the display method provided by the embodiment mainly controls the first blue sub-pixel B1 and the second blue sub-pixel B2 to alternately display blue light when the attenuation of the first blue sub-pixel B1 and the attenuation of the second blue sub-pixel B2 are smaller than the preset value, that is, the single first blue sub-pixel B1 or the single second blue sub-pixel B2 can ensure the display effect of the display panel; when the color attenuation degrees of the first blue sub-pixel B1 and the second blue sub-pixel B2 are greater than or equal to a preset value, that is, the first blue sub-pixel B1 and the second blue sub-pixel B2 age, the two are controlled to simultaneously display blue light, so that the defects caused by aging of the two sub-pixels are overcome, and the display panel displayed by the display method not only has a better display effect, but also has a longer service life.

That is, after the display panel displays one frame of picture, the first control module switches the blue sub-pixel displaying the current frame of picture to another blue sub-pixel. For example: if the current frame is displayed by the first blue sub-pixel B1, the first control module controls the second blue sub-pixel B2 to display the next frame.
