Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, 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, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The terminology used in the embodiments of the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used in the examples of this application and the appended claims, the singular forms "a", "an", and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.
As shown in fig. 1, fig. 2, fig. 3, and fig. 4, fig. 1 is a schematic structural diagram of a liquid crystal display panel in an embodiment of the present application, fig. 2 is a schematic diagram of a sensing area division of a partial cell thickness variation area in fig. 1, fig. 3 is a schematic sectional structural diagram of an AA' direction in fig. 1, and fig. 4 is a schematic flow chart of a display adjusting method in an embodiment of the present application. The embodiment of the application provides a display adjustment method, which is used for a liquid crystal display panel, wherein the liquid crystal display panel comprises a box thickness change area 1, the box thickness change area 1 is an area where the thickness of a liquid crystal box in the liquid crystal display panel can change in the using process, and can be specifically set according to the structure of the liquid crystal display panel, the thickness of the liquid crystal box is the size of the liquid crystal layer in the direction perpendicular to the plane of the liquid crystal display panel, the box thickness change area 1 is divided into a plurality of sensing areas 10, each sensing area 10 comprises a pressure sensing sensor 11 and at least one pixel 12, in the sensing area division mode shown in fig. 2, each smallest rectangular grid represents one pixel 12, every four adjacent pixels 12 form one sensing area 10, namely, each large rectangular grid represents one sensing area 10, each sensing area 10 is provided with a corresponding pressure sensing sensor 11, for example, one pressure-sensitive sensor 11 may be disposed in each sensing region 10, that is, the sensing region 10 and the pressure-sensitive sensor 11 are in one-to-one correspondence, or alternatively, a plurality of pressure-sensitive sensors 11 may be disposed in each sensing region 10, for example, one pressure-sensitive sensor 11 is disposed at each pixel 12, so that the sensing region 10 corresponds to four pressure-sensitive sensors 11, and the display adjustment method includes:
after the pressure sensing value in each sensing area 10 is obtained, in step 102, it is determined whether the pressure sensing value in each sensing area 10 reaches a preset condition.
103, adjusting the brightness and/or the chromaticity of the pixel 12 in the corresponding sensing area 10 according to the pressure sensing value, and then entering step 101 to monitor the pressure sensing value in real time or regularly;
and step 104, maintaining the brightness and/or the chromaticity of the pixels 12 in the corresponding sensing area 10.
Specifically, step 102 and step 104 are processes for a pressure sensing area. The pressure sensor 11 is used for sensing a compressive stress in a direction perpendicular to the liquid crystal display panel, in the manufactured and molded liquid crystal display panel, when the liquid crystal display panel is deformed by the influence of an ambient temperature to reduce the thickness of a liquid crystal cell in a certain sensing region 10, the compressive stress applied to the pressure sensor 11 in the sensing region 10 is increased, and when the liquid crystal display panel is deformed to increase the thickness of the liquid crystal cell in the certain sensing region 10, the compressive stress applied to the pressure sensor 11 in the sensing region 10 is decreased, so that a pressure sensing value is used for reflecting the magnitude of the compressive stress applied to the pressure sensor 11, the preset conditions can be set as required, for example, the standard thickness of the liquid crystal cell indicates the thickness of the liquid crystal cell of the liquid crystal display panel when the liquid crystal display panel is not influenced by the ambient temperature, and at this time, the display brightness and chromaticity of the liquid crystal display panel are both normal, when the pressure induction value of the pressure induction sensor 11 in a certain induction area 10 reaches a preset condition, it indicates that the difference of the liquid crystal box thickness of the induction area 10 is larger than that of a standard liquid crystal box thickness, at this time, the display brightness or chromaticity of the induction area 10 can be changed according to the original display mode, so that the display picture is not uniform, therefore, the pressure induction value in each induction area 10 can be periodically monitored and judged, and when the pressure induction value in a certain induction area 10 reaches the preset condition, the brightness and/or chromaticity of the pixel 12 in the area can be adjusted according to the pressure induction value, so as to compensate the display picture non-uniformity caused by the change of the liquid crystal box thickness; when the pressure sensing value in a certain sensing region 10 does not reach the preset condition, it indicates that the liquid crystal cell thickness of the sensing region 10 is the standard liquid crystal cell thickness, or the variation degree of the liquid crystal cell thickness relative to the standard liquid crystal cell thickness is small, and the brightness and/or the chromaticity of the pixel 12 do not need to be adjusted, and the display is still performed according to the current mode. In the display process of the liquid crystal display panel, the color of the pixel 12 is represented by the luminance and the chromaticity together, and the luminance and the chromaticity of the pixel 12 are presented according to the picture to be displayed, in this embodiment, the adjustment of the luminance of the pixel 12 refers to the adjustment on the basis of the luminance of the pixel 12 in the picture to be displayed, similarly, the adjustment of the chromaticity of the pixel 12 refers to the adjustment on the basis of the chromaticity of the pixel 12 in the picture to be displayed, and the step 104 of maintaining the luminance and/or the chromaticity of the pixel 12 in the corresponding sensing region 10 means not performing the adjustment, and directly presenting the corresponding luminance and the chromaticity according to the picture to be displayed. In addition, when a plurality of pressure-sensitive sensors 11 are correspondingly disposed in each sensing area 10, the pressure-sensitive values in the above steps 101 and 102 may be an average value of the pressure-sensitive values of all the pressure-sensitive sensors 11 in one sensing area 10, or may be a sum of the pressure-sensitive values of all the pressure-sensitive sensors 11 in one sensing area 10, as long as the pressure-sensitive values of all the pressure-sensitive sensors 11 in one sensing area 10 can be reflected. When one pressure-sensitive sensor 11 is correspondingly disposed in each sensing area 10, the pressure-sensitive value in the above steps 101 and 102 is the pressure-sensitive value of the pressure-sensitive sensor 11.
According to the display adjusting method in the embodiment of the application, the box thickness change area is divided into the plurality of sensing areas, the corresponding pressure sensing sensors are arranged in each sensing area, whether the sensing areas need to be adjusted or not is judged according to whether the pressure sensing values generated by the pressure sensing sensors meet the conditions or not, the brightness and/or the chromaticity of pixels of the sensing areas needing to be adjusted are adjusted, so that the color change of the pixels caused by the thickness change of the liquid crystal box is compensated, and the problem of uneven display pictures caused by the thickness change of the liquid crystal box is solved.
Optionally, as shown in fig. 5, fig. 5 is a detailed flowchart of the adjustment method shown in fig. 4, where the step 102 determines whether the pressure-induced value reaches a preset condition, and if so, the step 103 is executed to adjust the luminance and/or the chromaticity of the pixel in the corresponding sensing region according to the pressure-induced value, where the process includes:
and step 104, keeping the brightness of the pixels 12 in the corresponding sensing area 10.
Wherein, the first preset value is larger than or equal to the second preset value.
Specifically, when the pressure sensing value is greater than the first preset value, it indicates that the liquid crystal cell thickness of the sensing region 10 is reduced relative to the standard liquid crystal cell thickness, which may result in a reduction in the brightness of the pixel 12 in the sensing region 10, and therefore, the brightness of the pixel 12 may be increased to compensate for the brightness reduction caused by the reduction in the liquid crystal cell thickness; when the pressure sensing value is smaller than the second predetermined value, it indicates that the cell thickness of the sensing region 10 is increased relative to the standard cell thickness, which may result in the increased brightness of the pixel 12 in the sensing region 10, and therefore, the brightness of the pixel 12 may be decreased to compensate for the increased brightness caused by the increased cell thickness. It should be noted that the sequence between the steps illustrated in fig. 5 is only an example, and the sequence between the steps is not limited in the embodiment of the present application, for example, in other realizable implementations, step 1022 may be executed first to determine whether the pressure-induced value is smaller than the second preset value, and if not, step 1021 is executed again to determine whether the pressure-induced value is larger than the first preset value.
Optionally, in the step 1031, in the process of increasing the brightness of the pixel 12 in the corresponding sensing region 10, the increase amplitude of the brightness of the pixel 12 is positively correlated with the pressure sensing value; the magnitude of the decrease in brightness of the pixel 12 is inversely related to the magnitude of the pressure-induced value in decreasing the brightness of the pixel 12 in the corresponding sensing region 10.
Specifically, the pressure sensing value may reflect the thickness of the liquid crystal cell, and the larger the pressure sensing value is, the smaller the thickness of the liquid crystal cell is, that is, when the pressure sensing value is greater than the first preset value, the larger the pressure sensing value is, the larger the brightness reduction amplitude caused by the smaller the thickness of the liquid crystal cell is, so that the standard brightness can be achieved only by increasing the brightness more, even if the increase amplitude of the brightness of the pixel 12 is positively correlated with the pressure sensing value; the smaller the pressure-sensitive value is, the larger the liquid crystal cell thickness is, that is, when the pressure-sensitive value is smaller than the second preset value, the smaller the pressure-sensitive value is, the larger the brightness increase amplitude due to the increased liquid crystal display cell thickness is, and therefore, the standard brightness can be achieved only by reducing the brightness more, even if the reduced amplitude of the brightness of the pixel 12 is inversely related to the pressure-sensitive value. Therefore, more accurate brightness adjustment is realized, and the brightness adjustment is matched with the variation amplitude of the liquid crystal box thickness.
Optionally, the step 1031 of increasing the brightness of the pixel 12 in the corresponding sensing region 10 includes: adjusting the liquid crystal deflection direction of the pixels 12 in the corresponding sensing area 10 to improve the light transmittance; and/or, increasing the backlight brightness of the pixels 12 in the corresponding sensing region 10;
the step 1032 of reducing the brightness of the pixel 12 in the corresponding sensing region 10 includes: adjusting the liquid crystal deflection direction of the pixels 12 in the corresponding sensing area 10 to reduce the light transmittance; and/or to reduce the backlight brightness of the pixels 12 in the corresponding sensing region 10.
Specifically, the light transmittance of the liquid crystal layer can be changed by the liquid crystal deflection direction in the pixel 12, the higher the light transmittance is, the higher the brightness is, and the lower the light transmittance is, the lower the brightness is, so that the brightness of the pixel 12 can be increased or decreased by adjusting the liquid crystal deflection direction; in addition, the greater the backlight luminance of the pixel 12, the greater the corresponding light emission luminance, and the lower the backlight luminance of the pixel 12, the lower the corresponding light emission luminance, and therefore, the luminance of the pixel 12 may be increased or decreased by adjusting the backlight luminance of the pixel 12. The brightness adjustment of the pixels 12 can also be achieved jointly by adjusting both the liquid crystal deflection direction and the backlight brightness.
Optionally, each pixel 12 comprises a red sub-pixel, a green sub-pixel and a blue sub-pixel; as shown in fig. 6, fig. 6 is another detailed flowchart of the adjustment method shown in fig. 4, where the step 102 determines whether the pressure-induced value reaches a preset condition, and if so, the step 103 is executed to adjust the luminance and/or the chromaticity of the pixel in the corresponding sensing region according to the pressure-induced value, where the process includes:
1023, judging whether the pressure induction value is larger than a third preset value, if so, namely, if the pressure induction value is larger than the third preset value, entering a step 1033, and if not, entering a step 1024;
1033, reducing the brightness ratio of the blue sub-pixel in the pixel 12 in the corresponding sensing area 10, and then entering step 101 to monitor the pressure sensing value in real time or periodically;
and step 104, maintaining the chromaticity of the pixel 12 in the corresponding sensing area 10.
And the third preset value is greater than or equal to the fourth preset value.
Specifically, when the pressure sensing value is greater than the third preset value, it indicates that the thickness of the liquid crystal cell in the sensing region 10 is reduced relative to the standard thickness of the liquid crystal cell, which may cause the chromaticity of the pixel 12 in the sensing region 10 to be bluish, and therefore, the luminance ratio occupied by the blue sub-pixel in the pixel 12 may be reduced, so as to improve the bluish chromaticity caused by the reduction of the thickness of the liquid crystal cell; when the pressure sensing value is smaller than the fourth preset value, it indicates that the liquid crystal cell thickness of the sensing region 10 is increased relative to the standard liquid crystal cell thickness, which may cause the chromaticity of the pixel 12 in the sensing region 10 to be yellowish, and therefore, the luminance ratio of the red sub-pixel in the pixel 12 may be reduced, so as to improve the chromaticity yellowish caused by the increased liquid crystal cell thickness. For the adjustment of the luminance ratio of the sub-pixels with different colors in the pixel 12, the luminance ratio can be specifically adjusted by the liquid crystal deflection directions of the sub-pixels with different colors, for example, the liquid crystal deflection directions of the red sub-pixel and the green sub-pixel in the pixel 12 are controlled to be unchanged, the original light transmittance is kept, the liquid crystal deflection direction of the blue sub-pixel in the pixel 12 is adjusted, the corresponding light transmittance is reduced, and thus, the luminance ratio occupied by the blue sub-pixel in the pixel 12 is reduced; it can be understood that the light transmittance of the red sub-pixel and the green sub-pixel in the pixel 12 can be increased by controlling the liquid crystal deflection direction while keeping the liquid crystal deflection direction of the blue sub-pixel in the pixel 12 unchanged, thereby reducing the luminance ratio occupied by the blue sub-pixel in the pixel 12.
Optionally, in the step 1033, in the process of reducing the luminance proportion occupied by the blue sub-pixel in the pixel 12 in the corresponding sensing region 10, the reduction amplitude of the luminance proportion occupied by the blue sub-pixel is positively correlated with the pressure sensing value; in the step 1034, in the process of reducing the luminance proportion occupied by the red sub-pixel in the pixel 12 in the corresponding sensing region 10, the reduction amplitude of the luminance proportion occupied by the red sub-pixel is inversely related to the pressure sensing value.
Specifically, the pressure sensing value can reflect the thickness of the liquid crystal box, and the larger the pressure sensing value is, the smaller the thickness of the liquid crystal box is, that is, when the pressure sensing value is greater than a third preset value, the larger the pressure sensing value is, the larger the degree of bluish chromaticity of the pixel 12 is due to the smaller thickness of the liquid crystal box, so that the standard chromaticity can be achieved only by reducing the luminance proportion occupied by the blue sub-pixel in the pixel 12 to a greater extent, even if the reduction amplitude of the luminance proportion occupied by the blue sub-pixel is positively correlated with the pressure sensing value; the smaller the pressure sensing value is, the larger the liquid crystal box thickness is, that is, when the pressure sensing value is smaller than the fourth preset value, the smaller the pressure sensing value is, the larger the chroma yellowing degree of the pixel 12 due to the larger liquid crystal box thickness is, and therefore, the luminance proportion occupied by the red sub-pixel in the pixel 12 needs to be reduced to a greater extent, so that the standard chroma can be achieved, even if the reduction amplitude of the luminance proportion occupied by the red sub-pixel is inversely related to the pressure sensing value. Therefore, more accurate chromaticity adjustment is realized, and the chromaticity adjustment is matched with the variation amplitude of the liquid crystal box thickness.
Optionally, as shown in fig. 7, fig. 7 is a detailed flowchart of the display adjustment method shown in fig. 4, in the display adjustment method shown in fig. 7, the first preset value is equal to the third preset value, the second preset value is equal to the fourth preset value, step 1021 is combined with step 1023, step 1031 is combined with step 1033, step 1022 is combined with step 1024, and step 1032 is combined with step 1034, which includes the following specific steps, where step 102 determines whether the pressure sensing value reaches the preset condition, if yes, step 103 is performed, and a process of adjusting the brightness and/or chromaticity of the pixel in the corresponding sensing region according to the pressure sensing value includes:
and step 104, keeping the brightness and the chromaticity of the pixels 12 in the corresponding sensing area 10.
Wherein, the first preset value is larger than or equal to the second preset value.
Specifically, in step 2021, when the pressure sensing value is greater than the first preset value, it indicates that the liquid crystal cell thickness of the sensing region 10 is reduced relative to the standard liquid crystal cell thickness, so step 2031 is performed to adjust the brightness and chromaticity of the pixel 12 in the sensing region 10, and the specific process and principle of step 2031 may refer to the contents of step 1031 and step 1033; in step 2022, when the pressure sensing value is smaller than the second predetermined value, it indicates that the cell thickness of the sensing region 10 is larger than the standard cell thickness, so as to enter step 2032, and the specific process and principle of step 2032 can refer to the contents of step 1032 and step 1034. The problem of uneven display picture caused by the variation of the liquid crystal box thickness is solved by jointly adjusting the brightness and the chromaticity.
