[0050] FIG. 1 is a front view of an image display device according to some embodiments of the present disclosure. As shown in FIG. 1, some embodiments of the present disclosure provide an image display device 1000, which can be any device having a display function. For example, the image display device 1000 can be a mobile phone, a wireless device, a personal data assistant (PDA), a handheld or portable computer, a GPS receiver / navigator, a camera, an MP4 video player, a camcorder, a game console, a watch, a clock, a calculator, a television monitor, a flat panel display, a computer monitor, an automobile display (e.g., a speedometer display, etc.), a navigator, a cockpit controller and / or display, a display of a camera view (e.g., a display of a rear view camera in a vehicle), an electronic photo, an electronic billboard or sign, a projector, an architectural structure, a packaging and aesthetic structure (e.g., a display of an image of a piece of jewelry), etc. In FIG. 1, the image display device 1000 is taken as an example of a mobile phone. The image display device 1000 includes a display panel 100 through which an image is displayed.

[0051] The display panel 100 can be an electroluminescent display panel. When the display panel 100 is an electroluminescent display panel, the display panel 100 can be an organic electroluminescent (OLED) display panel or a quantum dot electroluminescent (QLED) display panel. In the following, the display panel 100 is taken as an example of an OLED display panel.

[0052] The display panel 100 includes a plurality of sub-pixels arranged in an array. Each sub-pixel includes a pixel driving circuit and a light emitting device electrically connected to the pixel driving circuit. The anode of the light emitting device is electrically connected to the pixel driving circuit, and the cathode of the light emitting device is grounded. A cross voltage can be formed between the anode and the cathode of the light emitting device under the action of the pixel driving circuit, so that the light emitting device emits light, and the brightness of the light corresponds to the size of the cross voltage.

[0053] According to the light emitting color of the light emitting device, the plurality of sub-pixels in the display panel can be divided into a plurality of categories. For example, the plurality of sub-pixels in the display panel can be divided into red sub-pixels, green sub-pixels, and blue sub-pixels. In some embodiments, the plurality of sub-pixels in the display panel can further include white sub-pixels.

[0054] There are various arrangements of the plurality of sub-pixels in the display panel, such as RGB arrangement, GGRB arrangement, WRGB arrangement, Pentile arrangement (P arrangement for short), diamond arrangement, and the like. FIG. 2 is a schematic diagram of an RGB arrangement. As shown in FIG. 2, in the RGB arrangement, one red sub-pixel, one green sub-pixel, and one blue sub-pixel adjacent to each other form one pixel, and the pixels are arranged in the display panel as an array unit. In the embodiments of the present disclosure, only the RGB arrangement is exemplarily described.

[0055] The light-emitting device in the red sub-pixel is a red light-emitting device, the light-emitting device in the green sub-pixel is a green light-emitting device, and the light-emitting device in the blue sub-pixel is a blue light-emitting device. Since the materials of the red light-emitting device, the green light-emitting device, and the blue light-emitting device are different, the light-emitting efficiencies of the red light-emitting device, the green light-emitting device, and the blue light-emitting device are different. For example, when the voltage difference between the anode and the cathode of the light-emitting device is the same, the luminance of the red light-emitting device, the green light-emitting device, and the blue light-emitting device is different. The following will be described in detail with examples.

[0056] Table 1

[0057] Table 1 shows the luminance test data of the light-emitting devices of various colors in a display panel. As shown in Table 1, when the voltage difference between the anode and the cathode of the light-emitting device is 6.6 V, the luminance of the light-emitting device is the largest. For example, the luminance of the red light-emitting device is 118.6 nit when the voltage difference is 6.6 V, at this time, the current in the red light-emitting device is 44.4 mA, the luminance of the green light-emitting device is 351.5 nit when the voltage difference is 6.6 V, at this time, the current in the green light-emitting device is 55.6 mA, and the luminance of the blue light-emitting device is 34.1 nit when the voltage difference is 6.6 V, at this time, the current in the blue light-emitting device is 99.6 mA. Therefore, when the voltage difference is the same, the luminance of the green light-emitting device is the highest, the luminance of the red light-emitting device is the second, and the luminance of the blue light-emitting device is the lowest.

[0058] The power is the product of the voltage and the current. When the voltage difference of the light-emitting device is the same, the greater the current in the light-emitting device, the greater the power consumption. For example, when the voltage difference is 6.6 V, the current in the red light-emitting device, the green light-emitting device, and the blue light-emitting device increases in turn, and therefore, when the voltage difference is 6.6 V, the power consumption of the red light-emitting device, the green light-emitting device, and the blue light-emitting device increases in turn.

[0059] The luminous efficiency of the light emitting device can be measured by unit current luminance, which is the ratio of the luminous brightness of the light emitting device to the current in the light emitting device, indicating the luminous brightness of the light emitting device when the light emitting device passes unit current, and the larger the value, the higher the luminous efficiency. As can be seen from Table 1, the luminous efficiency of the green light emitting device is the highest, the luminous efficiency of the red light emitting device is the second, and the luminous efficiency of the blue light emitting device is the lowest.

[0060] The color presented by the pixel is the color presented after the light emitted by the red light emitting device, the green light emitting device and the blue light emitting device is mixed, and the brightness of the pixel is about the sum of the brightness of the light emitted by the red light emitting device, the green light emitting device and the blue light emitting device. For example, as shown in Table 1, when the red light emitting device, the green light emitting device and the blue light emitting device all emit light with maximum brightness, the pixel presents white color, the brightness of the pixel is 505.5 nit, which is about the sum of 118.6 nit of red, 351.5 nit of green and 34.1 nit of blue; The total current of the pixel is 205.4 mA, which is slightly larger than the sum of 44.4 mA of red, 55.6 mA of green and 99.6 mA of blue, because when the red light emitting device, the green light emitting device and the blue light emitting device all emit light with maximum brightness, the load of the display panel increases, resulting in increased voltage drop loss.

[0061] Continuing to refer to the data in Table 1, the brightness contribution of the blue light emitting device in the pixel is 34.1 nit / 505.5 nit=6.75%, and the power consumption of the blue light emitting device in the pixel is 99.6 mA / 205.4 mA=48.49%; the brightness contribution of the green light emitting device in the pixel is 351.5 nit / 505.5 nit=69.54%, and the power consumption of the green light emitting device in the pixel is 55.6 mA / 205.4 mA=27.07%, the brightness contribution of the red light emitting device in the pixel is 118.6 nit / 505.5 nit=23.46%, and the power consumption of the red light emitting device in the pixel is 44.4 mA / 205.4 mA=21.62%.

[0062] Therefore, the power consumption of the blue light emitting device accounts for a large part of the total power consumption of the pixel, but the brightness of the blue light emitting device contributes less to the total brightness of the pixel, that is, the luminous efficiency of the blue light emitting device is lower. The power consumption of the red and green light emitting devices accounts for a small part of the total power consumption of the pixel, but the brightness of the red and green light emitting devices contributes more to the total brightness of the pixel, that is, the luminous efficiency of the red and green light emitting devices is lower. When the brightness of the blue light in the image displayed by the image display device accounts for a large proportion, the power consumption of the image display device will be large.

[0063] In view of this, the embodiment of the present disclosure provides an image display method, by reducing the luminance proportion of blue light emission, reducing the power consumption of the blue light emitting device, thereby reducing the power consumption of the image display device displaying the image.

[0064] FIG. 3 is a step block diagram of an image display method provided by the embodiment of the present disclosure. As shown in FIG. 3, the image display method comprises the following steps.

[0065] S200, in response to the low-power display mode, generating compensation image data according to the original image data;

[0066] S300, displaying the image according to the compensation image data.

[0067] The low-power display mode is a working mode of the image display device, and the image display device reduces the total power consumption of the image display device by reducing the power consumption for displaying the image in the low-power display mode. The image display device can enter the low-power display mode autonomously, or the image display device can enter the low-power display mode under the control of the user.

[0068] For example, the image display device enters the low-power display mode autonomously when a preset condition is met. For example, the image display device enters the low-power display mode autonomously when the remaining power of the image display device is lower than a preset value; the image display device enters the low-power display mode autonomously when the temperature of the image display device is higher than a preset value.

[0069] For example, the image display device enters the low-power display mode under the control of the user. For example, the image display device comprises a virtual switch button in the image user interface or a physical switch button on the shell, and the user controls the image display device to enter the low-power display mode by operating the switch button.

[0070] The original image data comprises a plurality of pixel data, and the pixel data is used to control the pixels in the display panel to emit light corresponding to the pixel data. For example, the number of pixel data is equal to the number of pixels in the display panel, and the pixel data corresponds to the pixels in the display panel one by one. For example, the display panel comprises four pixels, and the four pixels are arranged in 2*2. At this time, the original image data comprises four pixel data, the first pixel data is used to control the first row and the first column of pixels in the display panel to emit light, the second pixel data is used to control the first row and the second column of pixels in the display panel to emit light, and so on.

[0071] The pixel data includes gray scale values of multiple colors, and the gray scale values are used to control the luminance of the light emitting device. For example, the pixel data includes a blue gray scale value, a green gray scale value, and a red gray scale value, the blue gray scale value is used to control the luminance of the blue light emitting device, the green gray scale value is used to control the luminance of the green light emitting device, and the red gray scale value is used to control the luminance of the red light emitting device.

[0072] When the color correction parameter is n, the gray scale value is a, and the maximum gray scale value is A, the luminance of the light emitting device = the maximum luminance of the light emitting device * (a / A)^n.

[0073] For example, the gray scale value can be any integer from 0 to 255, i.e., including 256 gray scale values, and the color correction parameter is 2.2 (gamma 2.2). For example, the maximum luminance of the blue light emitting device is 34.1 nit, the maximum luminance of the green light emitting device is 351.5 nit, the maximum luminance of the red light emitting device is 118.6 nit, and the gray scale value is a, then the luminance of the blue light emitting device is 34.1 * (a / 255)^2.2 nit, the luminance of the green light emitting device is 351.5 * (a / 255)^2.2 nit, and the luminance of the red light emitting device is 118.6 * (a / 255)^2.2 nit.

[0074] Of course, the color correction parameter can also be 1 or 2, and the gray scale value can also be any integer from 0 to 1023, i.e., including 1024 gray scale values.

[0075] The original image data can be image data from a graphics processing chip (GPU) or image data from a system on a chip (SoC).

[0076] The multiple pixel data in the original image data includes to-be-compensated pixel data, the to-be-compensated pixel data includes a blue gray scale value and a first color gray scale value, and the blue gray scale value is greater than the first color gray scale value. The first color can be green or red, as long as the luminous efficiency of the first color light emitting device is higher than that of the blue light emitting device. For the convenience of description, only the first color is green is exemplarily introduced below, i.e., the first color gray scale value is the green gray scale value, and the first color light emitting device is the green light emitting device.

[0077] The luminous efficiency of the blue light emitting device in the pixel is the lowest, and the luminous efficiency of the red light emitting device and the green light emitting device is relatively high. Under the condition that the luminance of the pixel is constant, the power consumption of the pixel is relatively large when the blue gray scale value in the pixel data is large, and the power consumption of the pixel is relatively small when the blue gray scale value in the pixel data is small.

[0078] Since the blue gray scale value in the pixel data to be compensated is greater than the first color gray scale value, i.e., the blue gray scale value in the pixel data to be compensated is relatively large, the power consumption of the pixel corresponding to the pixel data to be compensated is relatively large. Therefore, the pixel data to be compensated needs to be compensated to reduce the power consumption of the pixel corresponding to the pixel data to be compensated.

[0079] The pixel data to be compensated is compensated to obtain compensated pixel data, the pixel data to be compensated and the compensated pixel data correspond to the same pixel in the display panel, and the image data including the compensated pixel data is compensation image data. The compensated pixel data includes the blue gray scale value and the first color gray scale value, the blue gray scale value of the compensated pixel data is less than the blue gray scale value of the pixel data to be compensated, and the first color gray scale value of the compensated pixel data is greater than the first color gray scale value of the pixel data to be compensated.

[0080] Since the blue gray scale value in the compensated pixel data is reduced, the brightness of the blue light emitting device in the pixel is reduced, thereby reducing the power consumption of the blue light emitting device. At the same time, the first color gray scale value of the compensated pixel data is greater than the first color gray scale value of the pixel data to be compensated, i.e., the first color gray scale value is increased, the brightness of the first color light emitting device is increased, thereby making up for the overall brightness reduction of the pixel caused by the brightness reduction of the blue light emitting device. Moreover, the light emitting efficiency of the first color light emitting device is greater than the light emitting efficiency of the blue light emitting device, the power consumption increase caused by the brightness increase of the first color light emitting device is less than the power consumption decrease caused by the brightness reduction of the blue light emitting device, thereby reducing the total power consumption of the pixel under the premise of small brightness change of the pixel.

[0081] The original image data can include one pixel data to be compensated or multiple pixel data to be compensated. The more the pixel data to be compensated in the original image data, the better the power consumption reduction effect. The pixel data to be compensated can belong to the pixel data in a certain fixed region of the image data. For example, the image displayed by the image display device includes a video image and a static image located around the video image, and the pixel data to be compensated can be the pixel data in the video image or the pixel data in the static image.

[0082] FIG. 4 is a partial sub-step block diagram of the image display method provided by the embodiment of the present disclosure. As shown in FIG. 4, in some embodiments, in step S200, the compensation image data is generated according to the original image data, including the following sub-steps.

[0083] S220, increasing the gray scale values of each color in the pixel data to be compensated to obtain increased pixel data;

[0084] S240, multiplying the increased blue gray scale value of the pixel data by the compensation coefficient to obtain a compensated blue gray scale value of the compensated pixel data, and multiplying the increased first color gray scale value of the pixel data by the compensation coefficient to obtain a compensated first color gray scale value of the compensated pixel data.

[0085] The gray scale values of each color in the pixel data to be compensated are increased respectively to obtain the increased pixel data. For example, the blue gray scale value, the green gray scale value and the red gray scale value are increased respectively. It should be noted that after the gray scale values of each color in the pixel data to be compensated are increased, the blue gray scale value is still greater than the first color gray scale value.

[0086] After the gray scale values of each color in the pixel data to be compensated are increased, the theoretical brightness of the increased pixel data will increase. The theoretical brightness is the sum of the brightness corresponding to the gray scale values of each color in the pixel data. For example, the theoretical brightness of the pixel data to be compensated is the brightness value calculated according to the gray scale values of each color in the pixel data to be compensated; the theoretical brightness of the increased pixel data is the brightness value calculated according to the gray scale values of each color in the increased pixel data.

[0087] For example, the red gray scale value in the pixel data to be compensated is 129, the green gray scale value is 60, and the blue gray scale value is 205. After being increased, the red gray scale value is 159, the green gray scale value is 90, and the blue gray scale value is 235. The color correction parameter n is 2.2 (gamma 2.2). Then, as shown in Table 1, the theoretical brightness of the pixel data to be compensated is 118.6*(129 / 255)^2.2+351.5*(60 / 255)^2.2+34.1*(205 / 255)^2.2=62.15 nit. After the gray scale values are increased by 30, the theoretical brightness of the pixel data is 118.6*(159 / 255)^2.2+351.5*(90 / 255)^2.2+34.1*(235 / 255)^2.2=106 nit. The brightness of the pixel will increase.

[0088] In order to keep the brightness of the pixel unchanged or change little, the increased gray scale values of each color need to be multiplied by a compensation coefficient (wherein the compensation coefficient is less than 1). Since the blue gray scale value is still greater than the first color gray scale value after the gray scale values of each color in the pixel data to be compensated are increased, when the gray scale values of each color are multiplied by the compensation coefficient, the blue gray scale value decreases more greatly, and the first color gray scale value decreases less greatly, so that the proportion of the first color gray scale value after multiplication in the sum of the gray scale values in the pixel data increases, and the proportion of the blue gray scale value after multiplication in the sum of the gray scale values in the pixel data decreases.

[0089] For example, if the compensation coefficient is 0.8, the multiplied red gray scale value is 159*0.8=127.2, and the integral value is 127; the multiplied green gray scale value is 90*0.8=72; and the multiplied blue gray scale value is 235*0.8=188. The sum of the gray scale values of each color in the to-be-compensated data is 129+60+205=394, the proportion of the green gray scale value in the sum of the gray scale values of each color is 60 / 394, and the proportion of the blue gray scale value in the sum of the gray scale values of each color is 205 / 394. The sum of the multiplied gray scale values of each color is 127+72+188=387, the proportion of the green gray scale value in the sum of the multiplied gray scale values of each color is 72 / 387 (where 387 is the sum of the gray scale values 127, 72 and 188), and the proportion of the blue gray scale value in the sum of the multiplied gray scale values of each color is 188 / 387. It can be seen that the proportion of the blue gray scale value decreases, and the proportion of the green gray scale value increases.

[0090] When the proportion of the blue gray scale value decreases and the proportion of the green gray scale value increases, the power consumption of the pixel is reduced without changing the luminance of the pixel.

[0091] FIG. 5 is a partial sub-step block diagram of the image display method provided by the embodiment of the present disclosure. As shown in FIG. 5, in some embodiments, in step S220, increasing the gray scale values of each color in the to-be-compensated pixel data includes the following sub-steps.

[0092] S222, increasing the blue gray scale value in the to-be-compensated pixel data by a first compensation value;

[0093] S223, increasing the first color gray scale value in the to-be-compensated pixel data by a second compensation value.

[0094] In actual application, the sum of the blue gray scale value and the first compensation value is the increased blue gray scale value, and the sum of the first color gray scale value and the second compensation value is the increased first color gray scale value. The first compensation value can be equal to the second compensation value.

[0095] For example, the sum of the blue gray scale value and the first compensation value is the increased blue gray scale value, the sum of the green gray scale value and the second compensation value is the increased green gray scale value, and the sum of the red gray scale value and the third compensation value is the increased red gray scale value.

[0096] For example, the first compensation value, the second compensation value and the third compensation value are all 30, the blue gray scale value in the to-be-compensated pixel data is 205, and after increasing by 30, it becomes 235; the green gray scale value in the to-be-compensated pixel data is 60, and after increasing by 30, it becomes 90; and the red gray scale value in the to-be-compensated pixel data is 129, and after increasing by 30, it becomes 159.

[0097] The sum of the gray scale values of each color in the to-be-compensated data is 129+60+205=394, the proportion of the green gray scale value in the sum of the gray scale values of each color is 60 / 394, and the proportion of the blue gray scale value in the sum of the gray scale values of each color is 205 / 394. The sum of the gray scale values of each color after increasing is 159+90+235=484, the proportion of the green gray scale value in the sum of the gray scale values of each color after increasing is 90 / 484, and the proportion of the blue gray scale value in the sum of the gray scale values of each color after increasing is 235 / 484. Since 235 / 484 is less than 205 / 394 and 90 / 484 is greater than 60 / 394, the proportion of the blue gray scale value is reduced and the proportion of the green gray scale value is increased, thereby reducing the luminous power consumption of the pixel.

[0098] It should be noted that the above takes the same first compensation value, second compensation value, and third compensation value as an example. At this time, it is equivalent to mixing white light data (for example, the red gray scale value is 30, the green gray scale value is 30, and the blue gray scale value is 30) into the to-be-compensated pixel data. According to the optical principle, after mixing a certain color of light into white light, the color tone of the mixed light remains unchanged, and only the saturation is reduced. Therefore, when the first compensation value, the second compensation value, and the third compensation value are the same, the color tone of the image displayed by the image display device is unchanged and the saturation is reduced, thereby reducing the impact on the user's viewing experience.

[0099] In actual application, the first compensation value and the second compensation value can also be different. For example, the second compensation value is greater than the first compensation value. For example, the first compensation value is 30 and the second compensation value is 40, so as to further increase the proportion of the first color gray scale value and reduce the proportion of the blue gray scale value. When the first compensation value and the second compensation value are different, in order to reduce the color difference between the compensated pixel data and the to-be-compensated pixel data, the difference between the first compensation value and the second compensation value needs to be set to be small.

[0100] The low-power-consumption display mode can include multiple levels, for example, the low-power-consumption display mode includes low, medium, and high levels. The level of the low-power-consumption display mode can be determined by the image display device autonomously or can be set by the user.

[0101] With reference back to FIG. 5, in some embodiments, in step S220, increasing the gray scale values of each color in the to-be-compensated pixel data further includes the following sub-steps.

[0102] S221, determining the first compensation value and the second compensation value according to the level of the low-power-consumption display mode.

[0103] In actual application, the first compensation value and the second compensation value corresponding to different levels of the low-power-consumption display mode are different in size. For example, the first compensation value and the second compensation value are 30 when the level is low, the first compensation value and the second compensation value are 35 when the level is medium, and the first compensation value and the second compensation value are 40 when the level is high.

[0104] The greater the first compensation value and the second compensation value, the smaller the proportion of the increased blue gray scale value, and the greater the proportion of the increased first color gray scale value.

[0105] FIG. 6 is a partial sub-step block diagram of the image display method provided by the embodiments of the present disclosure. As shown in FIG. 6, in some embodiments, the step S200 of generating compensation image data according to the original image data further includes the following sub-steps.

[0106] S230, obtaining a compensation coefficient according to the theoretical luminance of the pixel data to be compensated and the theoretical luminance of the increased pixel data.

[0107] For example, the red gray scale value of the pixel data to be compensated is 129, the green gray scale value is 60, the blue gray scale value is 205, the maximum luminance of the red light emitting device is 118.6 nit, the maximum luminance of the green light emitting device is 351.5 nit, the maximum luminance of the blue light emitting device is 34.1 nit, and the color correction coefficient n is 2.2 (gamma 2.2). Then the theoretical luminance of the pixel data to be compensated is 118.6*(129 / 255)^2.2+351.5*(60 / 255)^2.2+34.1*(205 / 255)^2.2=62.15 nit.

[0108] For example, the red gray scale value of the increased pixel data is 159, the green gray scale value is 90, the blue gray scale value is 225, the maximum luminance of the red light emitting device is 118.6 nit, the maximum luminance of the green light emitting device is 351.5 nit, the maximum luminance of the blue light emitting device is 34.1 nit, and the color correction coefficient n is 2.2 (gamma 2.2). Then the theoretical luminance of the increased pixel data is 118.6*(159 / 255)^2.2+351.5*(90 / 255)^2.2+34.1*(235 / 255)^2.2=106 nit.

[0109] In order to make the difference between the theoretical luminance of the pixel data to be compensated and the theoretical luminance of the compensated pixel data smaller, the greater the difference between the theoretical luminance of the pixel data to be compensated and the theoretical luminance of the increased pixel data, the greater the compensation coefficient, and the smaller the difference between the theoretical luminance of the pixel data to be compensated and the theoretical luminance of the increased pixel data, the smaller the compensation coefficient.

[0110] Further, the compensation coefficient can be 1 / n power of the ratio of the theoretical luminance of the pixel data to be compensated to the theoretical luminance of the increased pixel data, and n is a color correction parameter.

[0111] The compensation coefficient is η, the theoretical luminance of the pixel data to be compensated is L1, and the theoretical luminance of the increased pixel data is L2. Then η=(L1 / L2)^(1 / n).

[0112] For example, the theoretical brightness of the pixel data to be compensated is 62.15 nit, the theoretical brightness of the pixel data to be increased is 106 nit, and the color correction parameter is 2.2. Then, η = (62.15 / 106)^(1 / 2.2) ≈ 0.7845.

[0113] The red gray scale value in the compensated pixel data is 159*0.7845 = 124.74, and the integer is 124. The green gray scale value in the compensated pixel data is 90*0.7845 = 70.605, and the integer is 70. The blue gray scale value in the compensated pixel data is 235*0.7845 = 184.36, and the integer is 184. Then, 118.6*(124 / 255)^2.2 + 351.5*(70 / 255)^2.2 + 34.1*(184 / 255)^2.2 = 61.3 nit is the theoretical brightness of the compensated pixel data, which has a small difference from the theoretical brightness of the pixel data to be compensated.

[0114] The current in the light emitting device is approximately proportional to the brightness of the light emitting device.

[0115] Continuing to refer to Table 1, the current of the red light emitting device is 44.4 mA when the gray scale value is 255, and the current of the red light emitting device is 44.4*(129 / 255)^2.2 = 9.915 mA when the gray scale value is 129. The current of the red light emitting device is 44.4*(124 / 255)^2.2 = 9.089 mA when the gray scale value is 124. The current of the green light emitting device is 55.6 mA when the gray scale value is 255, and the current of the green light emitting device is 55.6*(60 / 255)^2.2 = 2.305 mA when the gray scale value is 60. The current of the green light emitting device is 55.6*(70 / 255)^2.2 = 3.235 mA when the gray scale value is 70. The current of the blue light emitting device is 99.6 mA when the gray scale value is 255, and the current of the blue light emitting device is 99.6*(205 / 255)^2.2 = 61.621 mA when the gray scale value is 205. The current of the blue light emitting device is 99.6*(184 / 255)^2.2 = 48.581 mA when the gray scale value is 184.

[0116] Therefore, the total current of the pixel of the display panel is 9.915 + 2.305 mA + 61.621 mA = 73.841 mA under the control of the pixel data to be compensated, and the total current of the pixel of the display panel is 9.089 mA + 3.235 mA + 48.581 mA = 60.905 mA under the control of the compensated pixel data. The power consumption reduction ratio of the pixel is (73.841-60.905) / 73.841 = 17.52%.

[0117] FIG. 7 is a partial sub-step block diagram of the image display method according to an embodiment of the present disclosure. As shown in FIG. 7, in some embodiments, the step S200 of generating the compensation image data according to the original image data further includes the following sub-steps.

[0118] S210, determining the pixel data with the blue gray scale value greater than the first color gray scale value in the original image data as the to-be-compensated pixel data.

[0119] The blue light emitting device has the lowest light emitting efficiency in the pixel, and the red light emitting device and the green light emitting device have higher light emitting efficiency. In the case of a certain light emitting brightness of the pixel, the power consumption of the pixel is larger when the blue gray scale value is greater than the red gray scale value or the green gray scale value in the pixel data. Therefore, the pixel data needs to be compensated to reduce the proportion of the blue gray scale value and thus reduce the power consumption of the pixel.

[0120] The original image data can include one to-be-compensated pixel data or multiple to-be-compensated pixel data. The more to-be-compensated pixel data in the original image data, the better the power consumption reduction effect. The to-be-compensated pixel data can belong to the pixel data in a certain fixed region of the image data. For example, the image displayed by the image display device includes a video image and a static image located around the video image. The to-be-compensated pixel data can be the pixel data in the video image or the pixel data in the static image.

[0121] In actual application, the size of the first color gray scale value and the blue gray scale value in each pixel data can be compared respectively, and the pixel data with the blue gray scale value greater than the first color gray scale value is determined as the to-be-compensated pixel data.

[0122] For example, the pixel data with the blue gray scale value less than the first color gray scale value is not the to-be-compensated pixel data, and the pixel data other than the to-be-compensated pixel data in the original image data and the compensation image data can be the same.

[0123] FIG. 8 is a step block diagram of another image display method according to an embodiment of the present disclosure. As shown in FIG. 8, in some embodiments, the image display method can further include the following steps.

[0124] S110, in response to the power saving mode, calculating the average value of each blue gray scale value and the average value of each first color gray scale value in the original image data;

[0125] S120, entering the low-power-consumption display mode when the average value of the blue gray scale value is greater than the average value of the first color gray scale value.

[0126] The power saving mode is a working mode of the image display device, and the image display device can reduce power consumption in the power saving mode. For example, the image display device can reduce power consumption by turning off an NFC module, a Bluetooth module, and the like in the power saving mode. The image display device can enter the power saving mode autonomously, or the image display device can enter the power saving mode under the control of a user.

[0127] For example, the image display device enters the power saving mode autonomously when a preset condition is met. For example, the image display device enters the power saving mode autonomously when a remaining power of the image display device is lower than a preset value, or when a temperature of the image display device is higher than a preset value.

[0128] For example, the image display device enters the power saving mode under the control of a user. For example, the image display device includes a virtual switch key in an image user interface or a physical switch key on a housing, and the user can make the image display device enter the power saving mode by operating the switch key.

[0129] For example, the average value of the blue gray scale values in the original image data is obtained by summing the blue gray scale values in each pixel data in the original image data and then dividing the sum by the number of the pixel data.

[0130] For example, the average value of the first color gray scale values in the original image data is obtained by summing the first color gray scale values in each pixel data in the original image data and then dividing the sum by the number of the pixel data.

[0131] When the average value of the blue gray scale values is greater than the average value of the first color gray scale values, the proportion of the blue gray scale values in the image data is large, and the power consumption of the display panel when displaying the image is large. Therefore, the low-power-consumption display mode needs to be entered to compensate for the original image data.

[0132] In some embodiments, in step S200, the compensation image data is generated according to the original image data, including the following sub-steps.

[0133] S201, each pixel in the original image data is determined as to-be-compensated pixel data.

[0134] That is, each pixel data in the original image data is compensated, so that the color saturation of the image displayed by the display panel is more uniform, and the display effect is better.

[0135] FIG. 9 is a structural block diagram of an image display device 1000 provided by an embodiment of the present disclosure. As shown in FIG. 9, the embodiment of the present disclosure further provides an image display device 1000, which includes a generating unit 200 and a display panel 100.

[0136] The generating unit 200 is configured to generate compensation image data according to the original image data in response to the low-power mode.

[0137] The original image data includes to-be-compensated pixel data at the first position, and the compensation image data includes compensated pixel data at the first position. The to-be-compensated pixel data and the compensated pixel data each include a blue gray scale value and a first color gray scale value. The blue gray scale value in the to-be-compensated pixel data is a first original gray scale value, and the first color gray scale value is a second original gray scale value. The blue gray scale value in the compensated pixel data is a first compensation gray scale value, and the first color gray scale value is a second compensation gray scale value. The first compensation gray scale value is smaller than the first original gray scale value, and the second compensation gray scale value is greater than the second original gray scale value.

[0138] The display panel 100 is configured to display an image according to the compensation image data.

[0139] The image display apparatus 1000 provided by the embodiments of the present disclosure obtains compensated pixel data after compensating to-be-compensated pixel data. The to-be-compensated pixel data and the compensated pixel data correspond to the same pixel in the display panel 100, and image data including the compensated pixel data is compensation image data. The compensated pixel data includes a blue gray scale value and a first color gray scale value. The blue gray scale value of the compensated pixel data is smaller than the blue gray scale value of the to-be-compensated pixel data, and the first color gray scale value of the compensated pixel data is greater than the first color gray scale value of the to-be-compensated pixel data. Because the blue gray scale value in the compensated pixel data is reduced, the luminance of the blue light-emitting device in the pixel is reduced, thereby reducing the power consumption of the blue light-emitting device. At the same time, the first color gray scale value of the compensated pixel data is greater than the first color gray scale value of the to-be-compensated pixel data, that is, the first color gray scale value is increased, the luminance of the first color light-emitting device is increased, thereby making up for the overall luminance reduction of the pixel caused by the luminance reduction of the blue light-emitting device. Moreover, the luminous efficiency of the first color light-emitting device is greater than that of the blue light-emitting device, the power consumption increase caused by the luminance increase of the first color light-emitting device is less than the power consumption decrease caused by the luminance reduction of the blue light-emitting device, and the total power consumption of the pixel is reduced under the premise that the luminance of the pixel changes little.

[0140] In some embodiments, the generating unit 200 is further configured to increase the gray scale values of each color in the to-be-compensated pixel data to obtain increased pixel data; multiply the blue gray scale value of the increased pixel data by a compensation coefficient to obtain the blue gray scale value of the compensated pixel data, and multiply the first color gray scale value of the increased pixel data by the compensation coefficient to obtain the first color gray scale value of the compensated pixel data. The compensation coefficient is less than 1.

[0141] In some embodiments, the generating unit 200 is further configured to obtain the compensation coefficient according to the theoretical brightness of the pixel data to be compensated and the theoretical brightness of the pixel data increased.

[0142] In some embodiments, the generating unit 200 is further configured to determine the compensation coefficient as the 1 / n power of the ratio of the theoretical brightness of the pixel data to be compensated and the theoretical brightness of the pixel data increased, where n is the color correction parameter.

[0143] In some embodiments, the generating unit 200 is further configured to increase the blue gray scale value in the pixel data to be compensated by a first compensation value, and increase the first color gray scale value in the pixel data to be compensated by a second compensation value.

[0144] In some embodiments, the generating unit 200 is further configured to determine the first compensation value and the second compensation value according to the level of the low-power display mode.

[0145] In some embodiments, the first compensation value can be equal to the second compensation value.

[0146] In some embodiments, the generating unit 200 is further configured to determine the pixel in the original image data whose blue gray scale value is greater than the first color gray scale value as the pixel data to be compensated.

[0147] In some embodiments, the generating unit 200 is further configured to:

[0148] In response to the power saving mode, calculate the average value of each blue gray scale value and the average value of each first color gray scale value in the original image data;

[0149] When the average value of the blue gray scale value is greater than the average value of the first color gray scale value, enter the low-power display mode.

[0150] In some embodiments, the generating unit 200 is further configured to determine each pixel in the original image data as the pixel data to be compensated.

[0151] When the image display device 1000 is a mobile terminal such as a mobile phone or a tablet computer, the image display device 1000 can include a system on chip (SoC) and a display module, and the display module includes a display panel 100 and a control board electrically connected to the display panel 100. When the image display device 1000 is working, the system on chip sends image data to the control board, and the control board sends control signals to the display panel 100 according to the image data to control the display panel 100 to display an image corresponding to the image data.

[0152] When the image display device 1000 is a terminal such as a notebook computer or a desktop computer, the image display device 1000 can include a central processing unit (CPU), a graphics processing chip (GPU), and a display module including the display panel 100 and a control board electrically connected to the display panel 100. When the image display device 1000 is in operation, the graphics processing chip sends image data to the control board, and the control board sends a control signal to the display panel 100 according to the image data to control the display panel 100 to display an image corresponding to the image data.

[0153] The generating unit 200 can be a system on chip, a central processing unit, or a graphics processing chip. For example, the system on chip, the central processing unit, or the graphics processing chip generates compensated image data and sends the compensated image data to the control board, and the control board generates a control signal according to the compensated image data to control the display panel 100 to display an image corresponding to the compensated image data.

[0154] The generating unit 200 can also be a module with computing capability already existing in the control board, such as a timing controller (T-con) or a data driving chip (D-IC). For example, the system on chip or the graphics processing chip sends original image data to the timing controller or the data driving chip, and the timing controller or the data driving chip generates compensated image data according to the original image data and generates a control signal according to the compensated image data to control the display panel 100 to display an image corresponding to the compensated image data.

[0155] The generating unit 200 can also be a separately arranged module. For example, the generating unit 200 is connected between the system on chip and the control board, the system on chip sends original image data to the generating unit 200, the generating unit 200 generates compensated image data according to the original image data and sends the compensated image data to the timing controller or the data driving chip, and the timing controller or the data driving chip generates a control signal according to the compensated image data to control the display panel 100 to display an image corresponding to the compensated image data. For another example, the generating unit 200 is connected between the graphics processing chip and the control board, the graphics processing chip sends original image data to the generating unit 200, the generating unit 200 generates compensated image data according to the original image data and sends the compensated image data to the timing controller or the data driving chip, and the timing controller or the data driving chip generates a control signal according to the compensated image data to control the display panel 100 to display an image corresponding to the compensated image data.

[0156] When the generating unit 200 is a module with computing capability already existing in the control board or a separately arranged module, part of the computing results can be pre-stored in the generating unit 200, and the pre-stored computing results are read by table lookup to reduce the amount of computation.

[0157] Exemplarily, the color correction parameter is n, the gray scale value is a, and the maximum gray scale value is A. The luminous brightness of the light emitting device = the maximum brightness of the light emitting device * (a / A)^n. The result of (a / A)^n can be pre-stored in the generation unit 200, and the pre-stored result is directly read when the theoretical brightness is calculated.

[0158] For example, the results of (0 / 255)^2.2, (1 / 255)^2.2, (2 / 255)^2.2, …, (255 / 255)^2.2 are calculated respectively, and the calculated results are pre-stored in the generation unit 200.
