Display method, display device and electronic equipment
[0001] The present application claims priority to the Chinese patent application No. 202410650656.1, filed on May 23, 2024, and entitled "Display method, display device and electronic equipment", the whole content of which is incorporated herein by reference. TECHNICAL FIELD
[0002] The present application relates to the technical field of display, in particular, to a display method, a display device and an electronic equipment. BACKGROUND
[0003] When using electronic equipment such as a mobile phone in different brightness environments, the screen needs to be adjusted to an appropriate brightness to ensure that the user has a comfortable visual experience and reduce the power consumption of the mobile phone. For example, the user can manually adjust the brightness in the mobile phone settings option, or the brightness automatic adjustment function can be turned on, so that the mobile phone automatically adjusts the screen brightness according to the ambient brightness.
[0004] There are generally two screen brightness adjustment methods, one is direct current (DC) dimming, which adjusts the current flowing through the organic light-emitting diode (OLED), and controls the luminous brightness by the current size. The larger the current, the greater the luminous brightness. The other is pulse width modulation (PWM) dimming, which controls the luminous brightness by adjusting the luminous time in a unit time. The longer the luminous time in a unit time, the greater the brightness.
[0005] At present, the OLED mobile phone screen uses DC dimming in high brightness and PWM dimming in low brightness. However, using PWM dimming in low brightness, the light-emitting duty cycle is small, which is easy to cause screen flicker and further cause visual fatigue. If the screen flicker is relieved by increasing the PWM dimming frequency, the high dimming frequency is easy to cause the increase of screen power consumption. SUMMARY

[0051] The technical solutions in the present application will be described below with reference to the accompanying drawings.
[0052] Reference to "one embodiment" or "some embodiments" or "one implementation" or "some implementations" means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the application. The appearances of the phrase "in one embodiment" or "in some embodiments" or "in one implementation" or "in some implementations" in various places in the specification are not necessarily all referring to the same embodiment, nor are they necessarily referring to some, but not all, embodiments. Rather, they mean that the particular feature, structure, or characteristic being referred to can be included in at least one embodiment of the application.
[0053] In various embodiments of the application, the first, second, etc. are just to represent that the multiple objects are different. For example, the first brightness scene and the second brightness scene are just to represent different brightness scenes. There should not be any impact on the brightness scenes themselves and the number, etc. The first, second, etc. above should not cause any limitation on the embodiments of the application.
[0054] The terms "comprise", "contain", "have" and their conjugates do not mean "consist of" unless otherwise specifically indicated.
[0055] In order to facilitate the understanding of the application, first, the technical terms involved in the application are explained:
[0056] Real pixel (real RGB): dividing a pixel into three sub-pixels, i.e. a red sub-pixel R, a green sub-pixel G and a blue sub-pixel B, which is the currently commonly used pixel arrangement.
[0057] Sub-pixel rendering (SPR): through rendering technology, adjacent pixels share sub-pixels, for example, one red sub-pixel R, one blue sub-pixel B and two green sub-pixels G together form two pixels to display an image in RGBG mode, instead of six sub-pixels forming two pixels.
[0058] Down-sampling: in the field of image processing, down-sampling can be to lower the resolution of an image.
[0059] Aperture ratio: the ratio between the area of the light passing part after removing the wiring part and the transistor part of each sub-pixel (usually hidden by a black matrix) and the overall area of each sub-pixel. The higher the aperture ratio, the higher the efficiency of light passing.
[0060] Dither: dithering algorithm, for systems with fewer available colors, the number of available colors can be increased by sacrificing resolution through dithering of color values.
[0061] Brightness: the luminous intensity per unit of projected area is called brightness, the unit is candela per square meter (cd / m 2), also called nit, 1 nit = 1 cd / m 2 .
[0062] As described above, in a low-brightness scene, if PWM dimming is used, screen flicker problems are prone to occur. There are two existing solutions to this problem. One is DC-like dimming, also known as mask dimming and dither smoothing. By invoking a layer mixer, the display image is mixed with other layers, and the luminance of the entire screen is effectively reduced, retaining the effect of DC-like dimming mode. However, this method has poor display uniformity in low-brightness, and color cast is prone to occur. At the same time, invoking the SOC layer processing function will increase the screen power consumption.
[0063] Another solution is to divide a sub-pixel into at least two sub-sub-pixels, and each sub-sub-pixel is controlled separately using a thin film transistor (TFT). In high-brightness, all sub-sub-pixels are turned on, and the display brightness is adjusted by DC dimming. In low-brightness, part of the sub-sub-pixels in the sub-pixel are turned off, and the driving current of the remaining sub-sub-pixels is increased, so that the effect of DC dimming is achieved, and the color cast and display unevenness caused by low driving current are avoided. However, this solution requires increasing the pixel circuit, which reduces the aperture ratio and has low practicability.
[0064] Therefore, the embodiments of the present application provide a display method to alleviate the screen flicker problem in low-brightness and reduce the screen power consumption.
[0065] FIG. 1 is a functional block diagram of a display device provided by an embodiment of the present application. The display device can include a display screen 110, a display effect controller 120, a display brightness controller 130, and an ambient light sensor 140. The ambient light sensor 140 can be used to detect the ambient light brightness. The display effect controller 120 and the display brightness controller 130 can be integrated in an SOC. The display brightness controller 130 can be used to analyze the instructions transmitted from the ambient light sensor 140, determine the brightness scene to be displayed, and then process the image data accordingly. The display effect controller 120 can perform gamma (GAMMA) adjustment and white balance adjustment in different brightness scenes to ensure the consistency of the display effect. The display screen 110 can be used to display images and present different display effects in different brightness scenes.
[0066] It should be understood that the above functional block diagram only schematically represents the functional devices that the display device can include, and should not be limited to the specific devices included in the display device.
[0067] FIG. 2 is a display method provided by an embodiment of the present application. The method can be executed by the display device described in FIG. 1. The method can include steps S210-S220.
[0068] S210, in the first brightness scene, turn off at least part of the plurality of sub-pixels.
[0069] S220, increase the current of the remaining sub-pixels in the plurality of sub-pixels.
[0070] For the above steps S210 and S220, the first brightness scene can be a scene where the ambient light brightness is low, for example, when the ambient light brightness range is less than 90 nit, it can be determined that the ambient light brightness is low, or when the ambient light brightness range is less than 80 nit, it can be determined that the ambient light brightness is low. The ambient light brightness range corresponding to the first brightness scene can be a preset range, and the present application does not limit the specific brightness corresponding to the first brightness scene. When the display device detects that the ambient light brightness falls within the preset range, it can be determined that the current brightness scene is the first brightness scene.
[0071] Specifically, the ambient light brightness can be detected by the ambient light sensor 140 described in FIG. 1, which can send a brightness instruction to the display brightness controller 130, which can be used to indicate the ambient light brightness, so that the display brightness controller 130 can turn off at least part of the plurality of sub-pixels according to the brightness instruction, and increase the current of the remaining sub-pixels.
[0072] In some embodiments, after turning off at least part of the sub-pixels, the display device can display the image in a true pixel display manner. The display device can include a plurality of pixels, and the plurality of pixels can include a plurality of sub-pixels, and the plurality of pixels can be displayed in the true pixel display manner or the sub-pixel rendering manner described above. At present, the display mode of the display screen is usually sub-pixel rendering, which reduces the number of sub-pixels and increases the area of the sub-pixels to reduce the current density of the pixels and improve the service life of the pixels. And because the human eye is more sensitive to green, the display mode can usually be RGBG. The display device can turn off at least part of the plurality of sub-pixels, that is, make at least part of the sub-pixels not emit light, and at the same time turn off the sub-pixel rendering algorithm, so that the red sub-pixel, the green sub-pixel and the blue sub-pixel form a pixel, and the display device displays the image in a true pixel manner.
[0073] In the prior art, if the DC dimming mode is used in a low brightness environment, since the driving current is small, and the image display is usually divided into 256 gray scales, 256 luminances need to be output, and it is difficult to distinguish the luminances. In the embodiments provided in the present application, at least part of the sub-pixels are turned off in a low brightness scene, and the current of the remaining sub-pixels is increased, or in other words, the driving current of the remaining sub-pixels is increased, for example, the current is increased from microampere level to milliamper level, which can more easily distinguish the luminances, and improve the color deviation and color unevenness problems caused by using the DC dimming in the low brightness scene; compared with using the PWM dimming in the low brightness scene, the screen flicker problem of the display screen can be alleviated, and the power consumption of the screen can be reduced.
[0074] The first brightness scene can be further divided into different sub-brightness scenes, and different sub-pixels are turned off in different sub-brightness scenes. The method can be referred to the flow diagram shown in FIG. 3, and the method can include steps S211-S213. Correspondingly, the sub-pixel display mode corresponding to the method can be as shown in FIG. 4.
[0075] S211, the first brightness scene includes a first sub-brightness scene, and at least part of the green sub-pixels in the plurality of green sub-pixels are turned off in the first sub-brightness scene, and the number of the at least part of the green sub-pixels can satisfy a first preset condition.
[0076] The first preset condition can be: wherein L is the number of the at least part of the green sub-pixels, and X is the total number of green sub-pixels in the display device. When the display device includes a plurality of display screens, X can be the total number of green sub-pixels of the display screen in the display state.
[0077] The first sub-brightness scene can be the scene with the highest brightness included in the first brightness scene. For example, when the brightness range corresponding to the first brightness scene is less than 90 nit, the brightness range of the first sub-brightness scene can be 60 nit-90 nit.
[0078] Exemplarily, (a) in FIG. 4 is a pixel display mode in a low brightness scene in the prior art, and (b) in FIG. 4 is a pixel display mode corresponding to a first sub-brightness scene provided by an embodiment of the present application. As shown in (a) in FIG. 4, the display device can include a red sub-pixel 310, a green sub-pixel 320, and a blue sub-pixel 330. The green sub-pixel 320 can include green sub-pixels 322 arranged in a 45° upward oblique direction and green sub-pixels 321 arranged in a 45° downward oblique direction. Correspondingly, the red sub-pixel can be regarded as being arranged in the 45° upward oblique direction, and the blue sub-pixel can be regarded as being arranged in the 45° upward oblique direction. The red, green, and blue sub-pixels together constitute an RGBG arrangement. The display mode of the display device is a sub-pixel rendering mode. Two green sub-pixels and one red sub-pixel and one blue sub-pixel together constitute two pixels, or in other words, one green sub-pixel arranged in the 45° upward oblique direction, one green sub-pixel arranged in the 45° downward oblique direction, and one red sub-pixel and one blue sub-pixel adjacent to the two green sub-pixels together constitute two pixels.
[0079] In the first sub-brightness scene, one-half of the green sub-pixels in (a) in FIG. 4 can be turned off. For example, the green sub-pixels arranged in the 45° upward oblique direction can be turned off, to obtain the display state shown in (b) in FIG. 4. The sub-pixels in the gray state in (b) in FIG. 4 are the turned-off sub-pixels. Alternatively, the green sub-pixels arranged in the 45° downward oblique direction can be turned off, that is, the green sub-pixels in the turned-off state in (b) in FIG. 4 can be turned on, and the green sub-pixels in the turned-on state can be turned off. Alternatively, one-half of the green sub-pixels arranged in the 45° upward oblique direction can be turned off, and one-half of the green sub-pixels arranged in the 45° downward oblique direction can be turned off. The present application does not limit the specific turning-off mode of the green sub-pixels. The remaining sub-pixels can be displayed in a true pixel mode, that is, each pixel is composed of a group of red, green, and blue sub-pixels, and there is no need to constitute a pixel by sharing sub-pixels with adjacent pixels.
[0080] It should be noted that (b) in FIG. 4 takes turning off one-half of the green sub-pixels as an example to introduce the display mode in the first sub-brightness scene, for example, the display mode at a brightness range node of the first sub-brightness scene, or in other words, the display mode at an end point of the brightness range of the first sub-brightness scene. When the brightness range corresponding to the first sub-brightness scene is 60 nit to 90 nit, the display mode shown in (b) in FIG. 4 can be the display mode at 60 nit. At the brightness node, the display mode of the display device can be a true pixel display mode. When the brightness corresponding to the first sub-brightness scene is other than 60 nit, the number of turned-off green sub-pixels of the display device can also be less than one-half of the total number of green sub-pixels. For example, when the luminance in the first sub-luminance scenario is reduced from 90 nit to 60 nit, the display device can gradually turn off the green sub-pixels until the number of turned-off green sub-pixels is In the display device, the number of green sub-pixels can be even or odd. When the number of green sub-pixels is odd, the number of turned-off green sub-pixels can be half of the total number of green sub-pixels minus 1.
[0081] It should be noted that the pixel structure shown in the figures is only used to illustrate the manner of turning off the sub-pixels, and the specific structure of the sub-pixels should not be limited. For example, the green sub-pixels shown in FIG. 4 are rectangular, and the red sub-pixels and the blue sub-pixels are square. The red sub-pixels, the green sub-pixels, and the blue sub-pixels can also be circular, rhombic, pentagonal, hexagonal, octagonal, or other shapes. For another example, the red sub-pixels, the green sub-pixels, and the blue sub-pixels shown in FIG. 4 are arranged along a 45° diagonal direction. The arrangement direction of the sub-pixels can also be other angles. The specific structure of the sub-pixels is not limited in the present application.
[0082] S212, the first luminance scenario includes a second sub-luminance scenario, the luminance of the second sub-luminance scenario can be lower than the luminance of the first sub-luminance scenario, and in the second sub-luminance scenario, at least part of the green sub-pixels, at least part of the red sub-pixels, and at least part of the blue sub-pixels are turned off, and the number of turned-off sub-pixels satisfies a second preset condition.
[0083] The second preset condition can be: wherein Y is the total number of red sub-pixels in the display device, M is the number of the at least part of the red sub-pixels, Z is the total number of blue sub-pixels in the display device, and N is the number of the at least part of the blue sub-pixels. When the display device includes a plurality of display screens, Y and Z can be the total number of red sub-pixels and blue sub-pixels of the display screen that is currently in a display state, respectively.
[0084] For example, when the luminance range of the first luminance scenario is less than or equal to 90 nit, and the luminance range of the first sub-luminance scenario is 60 nit to 90 nit, the luminance of the second sub-luminance scenario can be 30 nit to 60 nit.
[0085] Exemplarily, (c) in FIG. 4 is a display mode in which three fourths of the green sub-pixels, one half of the red sub-pixels, and one half of the blue sub-pixels are turned off. As shown in (c) in FIG. 4, in the second sub-luminance scenario, for the green sub-pixels, the display device can turn off the green sub-pixels arranged in the obliquely upward 45° direction, and turn off one half of the green sub-pixels arranged in the obliquely downward 45° direction. For the green sub-pixels arranged in the obliquely downward 45° direction, the green sub-pixels located on the same oblique line can be regarded as a group, and the green sub-pixels in the on state and the green sub-pixels in the off state in each group of green sub-pixels can be arranged alternately. Alternatively, the green sub-pixels arranged in the obliquely downward 45° direction can also be turned off, and one half of the green sub-pixels arranged in the obliquely upward 45° direction can also be turned off (not shown in the figure). For the red sub-pixels, the illustrated red sub-pixels are arranged in the obliquely upward 45° direction, the red sub-pixels located on the same oblique line can be regarded as a group, and the red sub-pixels in the off state and the red sub-pixels in the on state in each group of red sub-pixels can be arranged alternately. The turning off of the blue sub-pixels can be similar to that of the red sub-pixels, and the specific turning-off mode of the sub-pixels is not limited in the present application.
[0086] In this example, the display device can first turn off one half of the green sub-pixels, then turn off one fourth of the remaining green sub-pixels, and turn off one half of the red sub-pixels and one half of the blue sub-pixels, that is, the display device can first turn off part of the green sub-pixels in the manner shown in (b) in FIG. 4, and then further turn off part of the green sub-pixels, and the red sub-pixels and the blue sub-pixels on the basis of (b) in FIG. 4, so as to display in the manner shown in (c) in FIG. 4. For example, when the ambient light luminance gradually changes, the ambient light sensor 140 can first send a first luminance instruction to the display luminance controller 130, and the display luminance controller 130 turns off the sub-pixels in the display mode shown in (b) in FIG. 4 according to the first luminance instruction. Further, the ambient light sensor 140 can send a second luminance instruction to the display luminance controller 130, and the display luminance controller 130 turns off the sub-pixels in the display mode shown in (c) in FIG. 4 according to the second luminance instruction.
[0087] Alternatively, the display device can directly turn off three-quarters of the green sub-pixels, half of the red sub-pixels, and half of the blue sub-pixels, that is, directly change from the display mode shown in Figure 4(a) to the display mode shown in Figure 4(c). For example, when the ambient light brightness suddenly changes, the ambient light sensor 140 can directly send the second brightness command to the display brightness controller 130, and the display brightness controller 130 can directly turn off the sub-pixels according to the display mode shown in Figure 4(c) based on the second brightness command. In the second sub-brightness scenario, when the display device displays according to the display mode shown in Figure 4(c), the display device can turn off the green sub-pixels first, or turn off the blue sub-pixels first, or turn off the red sub-pixels first, or turn off the red, green, and blue sub-pixels simultaneously. This application does not limit the specific process of the display device turning off the sub-pixels.
[0088] It should be noted that (c) in Figure 4 is closed. Green sub-pixels red subpixels and The display method in the second sub-brightness scene is introduced using the blue sub-pixel as an example. For instance, it can be the display method at the brightness range node of the second sub-brightness scene. When the brightness range corresponding to the second sub-brightness scene is 30 nit to 60 nit, the display method shown in Figure 4(c) can be the display method at 30 nit. At this brightness node, the display device can be in true pixel display mode. Similar to the display method in the first sub-brightness scene, when the brightness of the second sub-brightness scene is other than 30 nit, the number of green sub-pixels turned off by the display device can also be less than [a certain value]. For example, when the brightness in this second sub-brightness scenario decreases from 60 nits to 30 nits, the display device can gradually turn off at least some of the green, red, and blue sub-pixels until the number of green sub-pixels turned off is [missing information]. The number of red sub-pixels is The number of blue sub-pixels is In this display device, the number of green sub-pixels can be even or odd, and the number of green sub-pixels can be a multiple of 4 or not. When the number of green sub-pixels is not a multiple of 4, turning off three-quarters of the green sub-pixels can be done by subtracting a certain number of green sub-pixels to make the number of green sub-pixels a multiple of 4, and then taking three-quarters of them. The number of red and blue sub-pixels that are turned off is similar to that of the green sub-pixels.
[0089] In some embodiments, the number of at least some sub-pixels turned off in the second sub-brightness scene can satisfy the following: That is, the display device displays the image in the true pixel mode after the at least part of the sub-pixels are turned off in the second sub-luminance scenario. As described above, the display device displays the image in the sub-pixel rendering mode when the sub-pixels are not turned off, displays the image in the true pixel mode when half of the green sub-pixels are turned off, that is, when the green sub-pixels, the red sub-pixels and the blue sub-pixels are turned off , and further, the number of the turned-off green sub-pixels, the turned-off red sub-pixels and the turned-off blue sub-pixels can be the same for the display device to display the image in the true pixel mode.
[0090] It should be noted that in the second sub-luminance scenario, the number of the turned-off sub-pixels at the end points and the intermediate values of the luminance range can satisfy the (c) in FIG. 4 is only an example of the display mode at the luminance node of the second sub-luminance scenario, and the number of the turned-off red sub-pixels, the turned-off green sub-pixels and the turned-off blue sub-pixels can be more than or less than that shown in the figure at the luminance node of the second sub-luminance scenario, and the sub-pixels can be turned off in groups of one red sub-pixel, one green sub-pixel and one blue sub-pixel based on the display mode shown in (b) in FIG. 4, and the red sub-pixel, the green sub-pixel and the blue sub-pixel in the same group can be adjacent sub-pixels.
[0091] The display device displays the image in the true pixel mode, which can simplify the rendering algorithm of the display device.
[0092] S213, the first luminance scenario includes a third sub-luminance scenario, the luminance of the third sub-luminance scenario is lower than the luminance of the second sub-luminance scenario, in the third sub-luminance scenario, at least part of the green sub-pixels in the plurality of green sub-pixels, at least part of the red sub-pixels in the plurality of red sub-pixels and at least part of the blue sub-pixels in the plurality of blue sub-pixels are turned off, and the number of the turned-off sub-pixels satisfies a third preset condition.
[0093] The third preset condition can be:
[0094] For example, when the luminance range of the first luminance scenario is less than 90 nit, the luminance range of the first sub-luminance scenario is 60 nit to 90 nit, and the luminance of the second sub-luminance scenario can be 30 nit to 60 nit, the luminance of the second sub-luminance scenario can be 1 nit to 30 nit.
[0095] For example, (d) in FIG. 4 is a display mode when seven-eighths of the green sub-pixels, three-fourths of the red sub-pixels, and three-fourths of the blue sub-pixels are turned off. Similarly to step S212, in the third sub-luminance scenario, the display device can first turn off one-half of the green sub-pixels to obtain the display mode shown in (b) in FIG. 4, then turn off one-half of the remaining green sub-pixels, one-half of the red sub-pixels, and one-half of the blue sub-pixels to obtain the display mode shown in (c) in FIG. 4, and then turn off one-half of the remaining green sub-pixels, one-half of the remaining red sub-pixels, and one-half of the remaining blue sub-pixels to obtain the display mode shown in (d) in FIG. 4.
[0096] Alternatively, the display device can directly turn off seven-eighths of the green sub-pixels, three-fourths of the red sub-pixels, and three-fourths of the blue sub-pixels to obtain the display mode shown in (d) in FIG. 4 directly from the display mode shown in (a) in FIG. 4.
[0097] It should be noted that the display mode shown in (d) in FIG. 4 can be a display mode when the display device is in the third sub-luminance scenario corresponding to the luminance range node, and the number of green sub-pixels turned off by the display device can be less than the number of red sub-pixels and the number of blue sub-pixels when the display device is in the first sub-luminance scenario corresponding to the luminance range node other than the node.
[0098] In some embodiments, the number of at least part of the sub-pixels turned off in the third sub-luminance scenario can satisfy: That is, the display device can also display an image in true-pixel mode after turning off at least part of the sub-pixels in the third sub-luminance scenario.
[0099] It should be noted that in the third sub-luminance scenario, the number of sub-pixels turned off at the endpoints and the intermediate value of the luminance range can satisfy Similarly to the second sub-luminance scenario, the number of red sub-pixels, green sub-pixels, and blue sub-pixels turned off at the luminance node in the third sub-luminance scenario can be more than shown in (d) in FIG. 4, or can be less than shown, and the display device can turn off the sub-pixels in groups of one red sub-pixel, one green sub-pixel, and one blue sub-pixel based on the display mode shown in (b) in FIG. 4, and the red sub-pixel, the green sub-pixel, and the blue sub-pixel in the same group can be adjacent sub-pixels, and only the number of sub-pixels turned off in the third sub-luminance scenario needs to be greater than the number of sub-pixels turned off in the second sub-luminance scenario.
[0100] The display device can adopt any one of the above S211-S213 to turn off at least part of the plurality of sub-pixels, and can increase the current of the remaining sub-pixels after turning off the sub-pixels in any one way. For example, the display device can increase the current of the remaining sub-pixels shown in (b) of FIG. 4, i.e., the current of the sub-pixels shown as red, green, and blue in (b) of FIG. 4, after turning off part of the sub-pixels in the method described in S211; can increase the current of the remaining sub-pixels shown in (c) of FIG. 4 after turning off part of the sub-pixels in the method described in S212; and can increase the current of the remaining sub-pixels shown in (d) of FIG. 4 after turning off part of the sub-pixels in the method described in S213. Since the brightness corresponding to the second sub-luminance scene is less than the brightness corresponding to the first sub-luminance scene, the driving current of the sub-pixels in the second sub-luminance scene can be less than the driving current of the sub-pixels in the first sub-luminance scene before turning off the sub-pixels, and the driving current of the remaining sub-pixels in the second sub-luminance scene can be greater than the driving current of the remaining sub-pixels in the first sub-luminance scene, or less than or equal to the driving current of the remaining sub-pixels in the first sub-luminance scene after turning off the sub-pixels and increasing the current of the remaining sub-pixels; that is, the driving current of the remaining sub-pixels shown in (c) of FIG. 4 can be greater than the driving current of the remaining sub-pixels shown in (b) of FIG. 4, or less than or equal to the driving current of the remaining sub-pixels shown in (b) of FIG. 4. Similarly, since the brightness corresponding to the third sub-luminance scene is less than the brightness corresponding to the second sub-luminance scene, the driving current of the sub-pixels in the third sub-luminance scene can be less than the driving current of the sub-pixels in the second sub-luminance scene before turning off the sub-pixels, and the driving current of the remaining sub-pixels in the third sub-luminance scene can be greater than the driving current of the remaining sub-pixels in the second sub-luminance scene, or less than or equal to the driving current of the remaining sub-pixels in the second sub-luminance scene after turning off the sub-pixels and increasing the current of the remaining sub-pixels; that is, the driving current of the remaining sub-pixels shown in (d) of FIG. 4 can be greater than the driving current of the remaining sub-pixels shown in (c) of FIG. 4, or less than or equal to the driving current of the remaining sub-pixels shown in (c) of FIG. 4.
[0101] It should be noted that in the above embodiment, the first brightness scene can include the above three different sub-brightness scenes, and different sub-pixels are closed in different ways. In the embodiment of the present application, the first brightness scene can also include only two different sub-brightness scenes. For example, the first brightness scene can include the first sub-brightness scene and the second sub-brightness scene, or the first sub-brightness scene and the third sub-brightness scene, or the second sub-brightness scene and the third sub-brightness scene, and the corresponding sub-pixel closing method is used to close the sub-pixels. The first brightness scene can also include more than three different sub-brightness scenes. For example, in addition to the above three sub-brightness scenes, the first brightness scene can also include a fourth sub-brightness scene, in which the display device can further close one-half of the red sub-pixels, one-half of the green sub-pixels, and one-half of the blue sub-pixels based on the sub-pixels closed in the third sub-brightness scene. The number of sub-brightness scenes included in the first brightness scene is not limited in the present application, and the number of sub-brightness scenes included in the first brightness scene and the number of closed sub-pixels can be preset according to the application scenario.
[0102] The first brightness scene is divided into different sub-brightness scenes, and different sub-pixels are closed in different ways in different sub-brightness scenes, so that the method can be applied to different application scenarios, the display effect of the display screen in different brightness scenes can be improved, and the display in different brightness scenes can be smoothly transitioned, reducing the visual fatigue of the user.
[0103] The method described in the above FIG. 2 to FIG. 4 is a display method in the first brightness scene, that is, a display method in the low brightness scene. The display device can also be set in a high brightness scene, which can also be referred to as a second brightness scene. The display device can use different display methods according to different brightness scenes, as shown in FIG. 5, which can include steps S510-S570.
[0104] S510, detecting the ambient light brightness, and determining whether the ambient light brightness is greater than or equal to a preset threshold.
[0105] As described above, the ambient light brightness can be detected by the ambient light sensor 140, and the ambient light sensor 140 can send a brightness instruction to the display brightness controller 130, which can be used to indicate the brightness of the ambient light.
[0106] The display brightness controller 130 can compare the brightness indicated by the brightness instruction with a preset threshold, and when the brightness indicated by the brightness instruction is greater than or equal to the preset threshold, the display brightness controller 130 can determine that the current brightness scene is the second brightness scene, as step S522; when the brightness indicated by the brightness instruction is less than the preset threshold, the display brightness controller can determine that the current brightness scene is the first brightness scene, as step S521.
[0107] Exemplarily, the preset threshold can be 90 nit, and when the brightness indicated by the brightness instruction is greater than or equal to 90 nit, it can be determined that the current brightness scene is the second brightness scene, and when the brightness indicated by the brightness instruction is less than 90 nit, it can be determined that the current brightness scene is the first brightness scene.
[0108] Further, when it is determined that the current brightness scene is the first brightness scene, the display device can perform steps S530-S550.
[0109] S530, image down-sampling is performed, and the image is enlarged to the resolution of the screen corresponding to the display device.
[0110] In some embodiments, in the first brightness scene, the display device can perform image down-sampling and enlarge the image to the resolution of the screen corresponding to the display device. The image down-sampling can be to reduce the resolution of the image. Enlarging the image size to the resolution of the screen corresponding to the display device can be achieved by repeating one sub-pixel in the image, for example, repeating one sub-pixel in the image by 4 times to increase the image size; enlarging the image to the resolution of the screen corresponding to the display device can mean that the pixel values corresponding to the width and height of the image are enlarged to adapt to the resolution of the screen, for example, the pixel values corresponding to the width and height of the image are consistent with the screen resolution.
[0111] Performing image down-sampling in the first brightness scene can make the image display clearer in the low brightness scene. For example, in the first brightness scene, when the display device displays document content, turning off part of the sub-pixels can easily cause the display of the text strokes to be missing, and down-sampling the image to make the text display larger can make it difficult for the turned-off sub-pixels to affect the overall display of the text, thereby improving the clarity of the displayed content in the low brightness scene and improving the user's visual fatigue problem.
[0112] S540, at least part of the sub-pixels are turned off to make the display device display the image in true pixel mode and increase the current of the remaining sub-pixels.
[0113] This step S540 is similar to steps S210 and S220 described above, and the way of turning off at least part of the sub-pixels is similar to S211-S213, and to avoid repetition, it will not be described here.
[0114] In a possible implementation, the display device can also not perform step S530, and directly perform step S540.
[0115] S550, performing GAMMA adjustment and / or white balance adjustment.
[0116] In some embodiments, in the first brightness scenario, the method can further include: performing white balance adjustment on the image.
[0117] The white balance adjustment is also the accuracy of mixing red, green and blue three primary colors of the display into white. Generally, the white light color temperature of the display is 6500K, if the white light color temperature is too high, the white light display will be blue, if the white light color temperature is too low, the white light display will be red, therefore, adjusting the white balance to make the white light color temperature 6500K can improve the display of the image color.
[0118] Exemplarily, the color temperature can be given by color coordinates x and y, x can represent the proportion of R component, and y can represent the proportion of G component. According to the input gray signal, the size of the output R component and G component can be adjusted first, so that the brightness of the output image is close to the target brightness, and then the current color coordinates are compared with the target color coordinates. If the x and y values are both greater than the target values, the B component can be increased; if the x and y values are both less than the target values, the B component can be decreased; if the x value is greater than the target value and the y value is close to the target value, the R component can be decreased; if the y value is greater than the target value and the x value is close to the target value, the G component can be decreased, so that the brightness of the output image meets the requirements.
[0119] In some embodiments, in the first brightness scenario, the method can further include: performing gamma adjustment on the image.
[0120] The gamma adjustment is also GAMMA adjustment. The output brightness of the display and the input voltage are in a power function relationship, the exponent value of the power function is also the GAMMA value, that is, the output brightness = the GAMMA power of the input voltage, the GAMMA adjustment is also the correction of the GAMMA value, and the GAMMA adjustment can also be called GAMMA correction. Generally, when the GAMMA value of the display is 2.2, the display effect is more suitable for human visual characteristics, if the GAMMA value is too large, the overall image display will be dark, and the details in the dark scene of the image are easy to be lost; if the GAMMA value is too small, the overall image display will be bright, and the level of detail will be poor. Therefore, in different brightness scenarios, the image can be subjected to GAMMA adjustment to improve the brightness and contrast of the image display.
[0121] Exemplarily, the display device can include an RGB mapping table, which can also be referred to as a look-up table (LUT), and the RGB mapping table can be a matching table of R values, G values and B values at different luminances. The display device can perform point-by-point conversion on input R values, G values and B values according to the RGB mapping table to obtain output values, so that the output luminance conforms to the GAMMA correction curve, and the display device can display the corresponding luminance according to the output R values, G values and B values.
[0122] It should be noted that the white balance adjustment and / or GAMMA adjustment of the image in the first luminance scene includes white balance adjustment and / or GAMMA adjustment in different sub-luminance scenes, that is, white balance adjustment and / or GAMMA adjustment can be performed in the first sub-luminance scene, the second sub-luminance scene and the third sub-luminance scene. The GAMMA adjustment between different sub-luminance scenes can use linear transition, for example, the output R value is 200 at 90 nit luminance according to the RGB mapping table, the output R value is 100 at 60 nit luminance according to the RGB mapping table, and when the luminance value is between 60 nit and 90 nit, the corresponding R value can be calculated by linear relationship without looking up the corresponding R value according to the RGB mapping table. Similarly, the G value and the B value can also be linearly changed. In addition, in the same luminance scene, the display screen can include a plurality of different luminance bands, and white balance adjustment and / or GAMMA adjustment can be performed on different luminance bands respectively, and the GAMMA adjustment between different luminance bands can also use linear transition. In the transition region of the adjacent two luminance bands, linear interpolation can be performed according to the R value, G value and B value determined in the two transition bands, for example, the output R value is 190 in one luminance band, and the output R value is 210 in another luminance band, and the corresponding R value in the transition region can be linearly changed with 190 and 210. The G value and the B value between different luminance bands can also be linearly changed, so that the luminance and color between the adjacent two transition bands can be smoothly transitioned.
[0123] It should be noted that according to the actual display effect, the display device can only perform white balance adjustment, only perform GAMMA adjustment, or perform both white balance adjustment and GAMMA adjustment. When the display device performs white balance adjustment and GAMMA adjustment, the white balance adjustment can be performed first, then the GAMMA adjustment can be performed, or the GAMMA adjustment can be performed first, then the white balance adjustment can be performed, or the white balance adjustment and the GAMMA adjustment can be performed simultaneously, which is not limited in the present application.
[0124] When it is determined that the current luminance scene is the second luminance scene, the display device can perform steps S560-S570.
[0125] S560, display the image in a sub-pixel rendering manner.
[0126] In the second brightness scenario, the display device can turn on the sub-pixel rendering algorithm, and display the image in a sub-pixel rendering manner, which can be as shown in (a) of FIG. 4.
[0127] S570, perform GAMMA adjustment and / or white balance adjustment.
[0128] The GAMMA adjustment and white balance adjustment methods in the second brightness scenario can be similar to those in the first brightness scenario, which will not be described herein.
[0129] Similar to the first brightness scenario, the second brightness scenario can also include multiple sub-brightness scenarios. The brightness ranges of the multiple sub-brightness scenarios of the second brightness scenario can be different, and the display device can perform GAMMA adjustment and / or white balance adjustment in the multiple sub-brightness scenarios of the second brightness scenario respectively, and in the same sub-brightness scenario, the display device can also perform GAMMA adjustment and / or white balance adjustment on different brightness bands respectively. The GAMMA adjustment between different sub-brightness scenarios in the second brightness scenario and between different brightness bands can use linear change transition.
[0130] It should be noted that when the second brightness scenario includes multiple sub-brightness scenarios and the brightness value switches between the ranges corresponding to the multiple sub-brightness scenarios, the display device can also adjust the display brightness by adjusting the current size, or in other words, the display device can also adjust the display brightness in a DC dimming manner in the second brightness scenario. For example, the second brightness scenario can include a fourth sub-brightness scenario, a fifth sub-brightness scenario, and a sixth sub-brightness scenario, and the brightness corresponding to the fourth sub-brightness scenario can be greater than the brightness corresponding to the fifth sub-brightness scenario, and the brightness corresponding to the fifth sub-brightness scenario can be greater than the brightness corresponding to the sixth sub-brightness scenario. When the brightness value switches from the brightness range corresponding to the fourth sub-brightness scenario to the brightness range corresponding to the fifth sub-brightness scenario, the display device can reduce the current of each sub-pixel, and when the brightness value switches from the brightness range corresponding to the fifth sub-brightness scenario to the brightness range corresponding to the fourth sub-brightness scenario, the display device can increase the current of each sub-pixel. In addition, in the second brightness scenario, the display device can not need to turn off the sub-pixels.
[0131] It should be noted that in the second brightness scenario, the ambient light brightness is high, and the display device can not perform image down-sampling.
[0132] The display method provided in the embodiments of the present application adopts the DC dimming mode for dimming in low-brightness scenes and high-brightness scenes, can reduce user visual fatigue, is more eye-friendly, and adopts software operation, does not need to change the existing pixel circuit, and is easier to apply and implement.
