Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.
The OLED display panel belongs to current drive, needs stable current to control light emission, and due to the reasons of process manufacturing, device aging and the like, a driving transistor (TFT) of a pixel circuit has different defect states, the threshold voltage Vth of the driving transistor has non-uniformity, and the display panel has a mura phenomenon.
When the gray scale difference between the current frame image and the next frame image of the display panel is large, the pixel driving circuit of the display panel needs to be switched to different bias voltages, and when the response of the defective driving transistor cannot keep up with the change speed of the external bias voltage, the driving transistor has a hysteresis effect, so that the pixel has a short-term afterimage phenomenon.
As shown in fig. 1, an embodiment of the present application provides a display method of a display panel, including:
s100: the method comprises the steps of obtaining a current frame image of a display panel and a next frame image adjacent to the current frame image.
In the embodiment of the present application, when the display panel displays, the display panel is formed by fast connecting frames of a plurality of frames, and one frame is generally called as one frame. In the embodiment of the application, the current frame image of the display panel is obtained, and the display retention time of the current frame image and the gray scale brightness of the current frame image can be obtained; and acquiring the highest gray-scale brightness of the next frame image adjacent to the current frame image. For example, the highest grayscale of the current frame image is W255, and the highest grayscale brightness is 120nit, i.e., L ═ 120nit @ W255. The retention time of the current frame image display may be 2S, 5S, 10S, etc. The highest gray-scale luminance of the next frame image may be, for example, 100nit, 90nit, etc.
S200: and judging whether the display retention time of the current frame image is greater than the preset time and whether the brightness corresponding to the highest gray scale of the next frame image is less than the preset brightness.
In the embodiment of the present application, the preset time is a manually set time, for example, the preset time is set to 5S, and in other embodiments, the preset time may also be 4S, 3S, 6S, and the like.
When the current frame image is switched from the high gray scale and the high brightness to the medium and low gray scale, short-term ghost and mura are likely to occur, and therefore, in the embodiment of the application, the preset brightness is smaller than the brightness corresponding to the highest gray scale of the current frame image. For example, the highest grayscale brightness of the current frame image is 120nit, the preset brightness in the embodiment of the present application is 100nit, and in other embodiments, the preset brightness may also be 90nit, 60nit, and the like. Specifically, the value of the preset luminance is determined according to the highest luminance to which different equivalent luminance modes can be applied.
And comparing the display retention time of the current frame image with a preset time, and judging whether the display retention time of the current frame image is greater than the preset time, for example, if the display retention time of the current frame image is 10S, the display retention time of the current frame image is greater than the preset time 5S. If the display retention time of the current frame image is 4S, the display retention time of the current frame image is less than the preset time, and the next frame image is displayed in the original display mode. Comparing the brightness corresponding to the highest gray scale of the next frame image with the preset brightness, wherein if the brightness corresponding to the highest gray scale of the next frame image is 90nit, the brightness corresponding to the highest gray scale of the next frame image is smaller than the preset brightness of 100 nit; if the brightness corresponding to the highest gray scale of the next frame image is 110nit, the brightness corresponding to the highest gray scale of the next frame image is judged to be greater than the preset brightness of 100nit, and the next frame image is still displayed in the original display mode. And executing S300 when the display retention time of the current frame image is greater than the preset time and the brightness corresponding to the highest gray scale of the next frame image is less than the preset brightness.
S300: after the current frame image is displayed, the mode is switched to the equivalent brightness mode to display the next frame image.
The equivalent luminance mode is a display mode capable of reducing image sticking and/or improving display unevenness (mura) at the same display luminance level.
In the embodiment of the application, the next frame of image displayed in the equivalent brightness mode is a static image, so that the correspondence of brightness switching can be ensured, and the display effect of the next frame of image cannot be influenced. In the embodiment of the application, the level of short-term afterimages can be reduced by switching to the equivalent brightness mode after the current frame image is displayed. In the embodiment of the application, when changing from high grey scale luminance to low grey scale luminance, the uneven phenomenon of demonstration appears easily in low grey scale luminance, when adopting the equivalent luminance mode of the embodiment of the application, can cover the mura phenomenon, improves the uneven risk of demonstration of low grey scale luminance, can promote the visual sensation that people's eye watched.
In the embodiment of the present application, the adjustment manner of the equivalent luminance mode includes increasing the high-level duty ratio in the emission power voltage, or decreasing the signal refresh frequency, or decreasing the reference voltage, and in other embodiments, other equivalent luminance modes may be used as long as the display mode capable of reducing the image sticking or improving the display unevenness under the same display luminance level can be achieved.
For example, when the high-level duty ratio (EM black insertion) in the emission power supply voltage is increased, the time ratio occupied by the black state of the display panel is increased, the light emitting time of a single sub-pixel in the display panel is shortened, and the brightness of the light emitting pixel of the single sub-pixel in a short pulse time is increased under the condition that the same pixel brightness is achieved, the brightness displayed on the display panel sensed by human eyes is the integral brightness in a certain time period, and therefore the brightness of the pixel seen by the human eyes is unchanged. The higher the individual subpixel luminance, the less pronounced the Vth and mura display of the array substrate. The mura phenomenon is caused by the fact that the characteristics of the TFT are not uniform in the whole display surface, and the mura phenomenon is more obvious under the condition that the display panel is low in brightness; in the case of high brightness, the TFT characteristics are not sufficient to cause non-uniformity of the display panel, and mura of the display panel is easily covered, causing the mura of the display panel to be inconspicuous. When the brightness of a single sub-pixel is increased, the difference between two adjacent frames can be reduced, and the ghost can be reduced. For example, the duty ratio of the high level in the transmission power supply voltage is 50%, and the duty ratio of the high level in the transmission power supply voltage can be increased to 80%. The method for improving the high-level duty ratio of the emission power supply voltage in the embodiment of the application is suitable for forming an equivalent display brightness mode with equivalent brightness, wherein the brightness of the next frame of image is less than 90 nit.
The refresh frequency refers to the number of times that the display panel refreshes the picture per second, the lower the refresh frequency, the more sufficient the charging time of the display, the improved the situation of local short-time charging insufficiency, and the Vth of the TFT affects the charging speed, and as the charging time increases, the charging difference is reduced. For example, when the refresh rate of the current frame image is 60HZ and the low gray-scale luminance is switched, the refresh rate is reduced to 40HZ, the Vth of the TFT has less influence on the charging difference, and therefore, the afterimage and display unevenness from the current frame image to the next frame image are improved. The reduced refresh frequency in the embodiment of the present application is suitable for the luminance of the next frame image being less than 60nit, and an equivalent display luminance mode with equivalent luminance is formed.
The reference voltage (Vref) is reduced, namely, the initialization voltage value is reduced, and the Vref value is a negative value, so that the initialization voltage value is reduced, the voltage difference is favorably reduced, the charging time of the capacitor is shortened, and the problem of image sticking is weakened to a certain extent.
In the embodiment of the application, on the display panel, whether the display retention time of the current frame image is greater than the preset time or not and whether the brightness corresponding to the highest gray scale of the next frame image is less than the preset brightness or not are judged, and under the condition that the display retention time of the current frame image is greater than the preset time or not, when the display of the current frame image is finished, the display is switched to the equivalent brightness mode, so that short-term ghost shadow is reduced or uneven display is improved, and the visual perception is.
In an embodiment of the present application, the step S200 of determining whether the display retention time of the current frame image is greater than the preset time and whether the brightness corresponding to the highest gray scale of the next frame image is less than the preset brightness includes:
s210: and judging whether the display retention time of the current frame image is greater than the preset time.
In the embodiment of the present application, it is determined whether the display retention time of the current frame image is greater than the preset time, and S220 is executed only when the display retention time of the current frame image is greater than the preset time, otherwise, the display retention time of the current frame image is less than or equal to the preset time, and S400 is executed to display the next frame image in the original display mode.
S220: and judging whether the brightness corresponding to the highest gray scale of the next frame image is less than the preset brightness. If so, executing S300, otherwise executing S400 to display the next frame image in the original display mode.
In the embodiment of the application, when it is determined whether to switch to the equivalent brightness mode, it is determined first whether the display retention time of the current frame image is greater than the preset time through step-by-step determination, if yes, step S220 is executed, and if no, step S220 is not required, so that the determination steps can be reduced, and the program can be saved.
In an embodiment of the present application, the switching to the equivalent luminance mode in step 300, as shown in fig. 3, includes:
s310: and calling the equivalent brightness mode, and displaying the next frame of image in the equivalent brightness mode, wherein the equivalent brightness mode establishes a corresponding conversion relation with the original display mode in advance.
When the brightness and gray scale mapping is carried out, the program is complex, the occupied resources are more, and in order to reduce the complexity of the program, in the embodiment of the application, the equivalent brightness mode establishes a corresponding conversion relation with the original display mode in advance and stores the equivalent brightness mode in the memory; when the equivalent brightness mode is called, the equivalent brightness mode can be directly obtained from the memory, simple conversion is carried out, and conversion of the equivalent brightness is realized, for example, the pre-stored original display mode is the equivalent brightness mode corresponding to the common display mode (such as Normal mode), and the corresponding brightness is 80 nit; if the difference between the brightness of the next frame image and the brightness of the pre-stored original display mode is within the preset range, for example, in the embodiment of the present application, the preset threshold is ± 10% of the pre-stored original display mode, that is, under the condition that the brightness of the next frame image is 80nit (1 ± 10%), the equivalent brightness mode of the next frame with the brightness of 80nit (1 ± 10%) can be obtained by directly adopting the equivalent brightness mode that establishes the corresponding conversion relationship with the original display mode in advance, and the equivalent brightness mode of the next frame image is directly obtained without performing gray scale mapping, so that the operation complexity is reduced.
For example, the luminance of the original display mode is 80nit, and an equivalent luminance mode of a corresponding conversion relation related to the luminance is established, for example, the luminance of the original display mode is 80nit, and the equivalent luminance mode is to increase the duty ratio of a high level in the emission power supply voltage to 82%; the brightness of the next frame image is 72nit, and the equivalent brightness mode is to increase the high-level duty ratio in the emission power supply voltage to 75%. In the embodiment of the application, when the equivalent brightness mode is called, the brightness of the equivalent brightness mode which can reach the next frame image is consistent with the brightness of the equivalent brightness mode W255 of the previous display mode, gray scale mapping is not needed, display is directly switched, and the operation complexity can be reduced.
In another embodiment, the switching to the equivalent luminance mode in step 300 displays the next frame of image, as shown in fig. 4, including:

In the embodiment of the application, the maximum brightness in the pixel of the next frame corresponds to the maximum gray scale brightness W255 of the equivalent brightness mode, and the corresponding driving voltage value is searched according to the brightness of W255; when the driving voltage value is used as the maximum gray level W255, a mapping table is established between the brightness corresponding to other different gray levels and the driving voltage value of the maximum gray level W255, and the driving voltage value corresponding to the gray level brightness corresponding to the next frame image can be obtained from the mapping table and driven. The switching to the equivalent brightness mode in the embodiment of the application can be suitable for the equivalent brightness mode with multiple brightness levels, the requirement on the gray scale brightness of the next frame of image is low, the complexity of operation can be reduced, and the display running speed of the display panel is improved.
For example, if the brightness L1 of the original maximum gray level W130 of the next frame image corresponds to the brightness of the maximum gray level W255 in the equivalent brightness mode, if the brightness of the original gray levels of the other pixels of the next frame image is the brightness L2 of W110, the gray level value W230 is obtained by searching according to the gray level value L2 corresponding to the gamma curve corresponding to the maximum gray level W255, and the driving voltage value is searched from the mapping table according to the obtained gray level value W230, so as to drive the display panel to display the next frame image in the equivalent brightness mode.
In the embodiment of the present application, the maximum brightness of the pixel of the next frame image corresponds to the maximum gray-scale brightness of the equivalent brightness mode. In other embodiments, the pixel operation brightness horizontal run of the next frame image may correspond to the maximum gray-scale brightness of the equivalent brightness mode.
