[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to Chinese patent application number 2023110387293, filed on August 16, 2023, entitled “Display device and control method of display device”, which is incorporated herein by reference in its entirety. Technical Field

[0003] The present application relates to the field of display technology, and in particular to a display device, a method for controlling a display device, a control device for a display device, a computer device, a storage medium, and a computer program product. Background Art

[0004] With the development of display technology, display screens are becoming increasingly widely used. Existing display screens typically use RGB (three primary colors) light-emitting elements to display different colors, and white light is generally emitted by mixing the three RGB primary colors. However, in typical video images, there are very few pixels with pure color tones, and the vast majority of screen pixels contain white components. This is especially true when displaying text, often using a pure white background. Because the luminous efficiency of RGB primary color light-emitting elements is typically less than 40 lm / W, and the color rendering index of the white light emitted after mixing is low, existing display screens tend to have low luminous efficiency, high power consumption, and poor display quality.

[0055] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0056] In one embodiment, the present application provides a display device comprising a plurality of display pixels, each display pixel comprising a white light-emitting element and at least one color light-emitting element, wherein the number of the color light-emitting elements is less than or equal to the number of the white light-emitting elements.

[0057] Among them, the color light-emitting elements are primarily used to emit pure color components. The white light-emitting elements are primarily used to emit white components. Each display pixel in a display device can include a white light-emitting element and at least one color light-emitting element. For example, as shown in Figure 1, when the color light-emitting elements include red (R), green (G), and blue (B), each display pixel in the display device can include a white light-emitting element, as well as one, two, or three of the red, green, or blue light-emitting elements. Generally, the luminous efficiency of white light-emitting elements is around 150 lm / W, while the luminous efficiency of color light-emitting elements is less than 40 lm / W. Therefore, the luminous efficiency of white light-emitting elements is typically 3-10 times higher than that of color light-emitting elements. Furthermore, video images typically contain relatively few display pixels with pure color tones (100% color saturation), while the vast majority of display pixels contain white components. In this case, using color light-emitting elements primarily to emit pure color components and white light-emitting elements primarily to emit white components can improve the luminous efficiency of the display device, reduce power consumption, and maintain the display quality of the display device.

[0058] The number of a certain color light-emitting element is less than or equal to the number of white light-emitting elements, which can be understood as the total number of each color light-emitting element in the display device is less than or equal to the total number of white light-emitting elements. For example, the total number of red light-emitting elements in the display device is less than or equal to the total number of white light-emitting elements, the total number of green light-emitting elements in the display device is less than or equal to the total number of white light-emitting elements, and the total number of blue light-emitting elements in the display device is less than or equal to the total number of white light-emitting elements. The total number of a certain color light-emitting element in the display device is calculated by summing the number of a certain color light-emitting element in each display pixel. In this embodiment, the number of a certain color light-emitting element in each display pixel is one. Similarly, the total number of white light-emitting elements in the display device is calculated by summing the number of white light-emitting elements in each display pixel. In this embodiment, each display pixel includes one white light-emitting element. In this case, the number of white light-emitting elements in the display device is equal to the number of display pixels. Since the human eye's color resolution is typically only 1 / 4 of its brightness resolution, in current computer video encoding and digital television transmission standards, color data is only about 1 / 4 of brightness data. Therefore, even if the color resolution is displayed at the same brightness resolution, true color high-resolution video cannot be achieved. Therefore, when the number of color light-emitting components is less than or equal to the number of white light-emitting components, costs can be effectively reduced without affecting the human eye's perception. In a detailed embodiment, the white LED light-emitting component can be a white LED light-emitting chip, and the color LED light-emitting component can be a color LED light-emitting chip. The color LED light-emitting chip can include a red light-emitting chip, a green light-emitting chip, and a blue light-emitting chip.

[0059] In this embodiment, the display device includes multiple display pixels, each of which includes a white light-emitting element and at least one color light-emitting element, with the number of color light-emitting elements being less than or equal to the number of white light-emitting elements. Since the luminous efficiency of white light-emitting elements is typically around 150 lm / W, this display device and display screen can effectively improve the display device's luminous efficiency and reduce power consumption.

[0060] In one embodiment, the colored light emitting element is a red light emitting element, a green light emitting element or a blue light emitting element.

[0061] Among them, the red light-emitting element can be used to emit red light, the green light-emitting element can be used to emit green light, and the blue light-emitting element can be used to emit blue light. When each display pixel includes a white light-emitting element and at least one color light-emitting element, the various color light-emitting elements mixed with the white light-emitting element can display different colors. In addition, the types and quantities of color light-emitting elements included in each adjacent pixel can be different. For example, when a pixel includes a white light-emitting element, a red light-emitting element, and a green light-emitting element, one of the adjacent pixels can include a white light-emitting element and a blue light-emitting element.

[0062] In this embodiment, the color light emitting element is a red light emitting element, a green light emitting element or a blue light emitting element, which can emit light of different colors to ensure the display effect of the display device.

[0063] In one embodiment, as shown in FIG1 , each display pixel includes a red light-emitting element, a green light-emitting element, a blue light-emitting element, and a white light-emitting element. Since most colors can be produced by synthesizing red, green, and blue in different proportions, in order to display richer colors, each display pixel in the display device can include a red light-emitting element, a green light-emitting element, a blue light-emitting element, and a white light-emitting element. Furthermore, colors can generally be divided into pure color components and white components. The red light-emitting element, the green light-emitting element, and the blue light-emitting element are mainly used to emit pure color components in the color, and the white light-emitting element is mainly used to emit white components in the color. In this way, not only can more colors be displayed, but the luminous efficiency of the display device will also be increased, and power consumption will be reduced.

[0064] In this embodiment, each display pixel includes a red light-emitting element, a green light-emitting element, a blue light-emitting element, and a white light-emitting element, enabling the display device to display a richer range of colors. Furthermore, because the white light-emitting element has a higher luminous efficiency and primarily emits white light, this not only reduces the distortion of the white light emitted by the red, green, and blue light-emitting elements, but also improves the luminous efficiency of the display device and reduces power consumption.

[0065] In one embodiment, as shown in FIG2 , each display pixel includes a white light emitting element and one of a red light emitting element, a green light emitting element, and a blue light emitting element, and three adjacent display pixels include a group of color light emitting elements.

[0066] Among them, the red light-emitting element, the green light-emitting element, and the blue light-emitting element can be a group of color light-emitting elements. Exemplarily, when three adjacent display pixels are respectively the first display pixel, the second display pixel, and the third display pixel, the first display pixel can include a white light-emitting element and a red light-emitting element, the second display pixel can include a white light-emitting element and a green light-emitting element, and the third display pixel can include a white light-emitting element and a blue light-emitting element. In this way, the red light-emitting element in the first display pixel, the green light-emitting element in the second display pixel, and the blue light-emitting element in the third display pixel can constitute a group of color light-emitting elements in the three adjacent display pixels. Furthermore, the arrangement direction of the three adjacent display pixels can be from left to right or from top to bottom. Because the human eye has a low resolution for color, in this embodiment, the three adjacent display pixels are provided with a group of color light-emitting elements, which can also achieve a display resolution similar to that of each display pixel including a group of color light-emitting elements, that is, it can ensure a certain display effect.

[0067] In this embodiment, each display pixel includes a white light-emitting element and one of a red light-emitting element, a green light-emitting element, and a blue light-emitting element, and three adjacent display pixels include a group of color light-emitting elements. This reduces the cost of the light-emitting elements while ensuring the display effect.

[0068] In one embodiment, as shown in FIG3 , each display pixel includes a white light emitting element and two of a red light emitting element, a green light emitting element, and a blue light emitting element, and three adjacent display pixels include two groups of color light emitting elements.

[0069] The red light-emitting element, the green light-emitting element, and the blue light-emitting element may be a group of color light-emitting elements. For example, when three adjacent display pixels are a first display pixel, a second display pixel, and a third display pixel, the first display pixel may include a white light-emitting element, a red light-emitting element, and a green light-emitting element; the second display pixel may include a white light-emitting element, a green light-emitting element, and a blue light-emitting element; and the third display pixel may include a white light-emitting element, a blue light-emitting element, and a red light-emitting element. Thus, the red light-emitting element in the first display pixel, the green light-emitting element in the second display pixel, and the blue light-emitting element in the third display pixel may constitute one group of color light-emitting elements in the three adjacent display pixels. The green light-emitting element in the first display pixel, the blue light-emitting element in the second display pixel, and the red light-emitting element in the third display pixel may constitute another group of color light-emitting elements in the three adjacent display pixels. Similarly, the arrangement direction of the three adjacent display pixels may be from left to right or from top to bottom.

[0070] In this embodiment, each display pixel includes a white light-emitting element and two of a red light-emitting element, a green light-emitting element, and a blue light-emitting element, and three adjacent display pixels include two groups of color light-emitting elements. This reduces the cost of the light-emitting elements while ensuring the display effect.

[0071] In one embodiment, the present application further provides a method for controlling a display device, for controlling the display device in any of the above embodiments. As shown in FIG4 , the method includes steps 202 , 204 , 206 , and 208 .

[0072] Step 202: Acquire the light emitting data of the color light emitting element.

[0073] The luminescence data of the color light-emitting components can be obtained based on video data input by the user, where the video data input by the user includes color information for each display pixel. The luminescence data of the color light-emitting components is used to control the luminescence brightness of the color light-emitting components. When there is more than one type of color light-emitting component, the luminescence data of each type of color light-emitting component can be obtained. For example, when the color light-emitting components include red, green, and blue light-emitting components, obtaining the luminescence data of the color light-emitting components may include obtaining the luminescence data of the red light-emitting component, the luminescence data of the green light-emitting component, and the luminescence data of the blue light-emitting component. The luminescence data of the red light-emitting component can be used to control the brightness of the red light emitted by the red light-emitting component, the luminescence data of the green light-emitting component can be used to control the brightness of the green light emitted by the green light-emitting component, and the luminescence data of the blue light-emitting component can be used to control the brightness of the blue light emitted by the blue light-emitting component. Furthermore, by mixing red, green, and blue light of different brightnesses, more different colors of light can be emitted.

[0074] Specifically, the light emitting data of the color light emitting element in a certain display pixel in the display device can be obtained according to the color information of the display pixel.

[0075] Step 204 : Obtain the luminous data of the white luminous component according to the luminous data of the color luminous component.

[0076] The luminous data of the white light-emitting component can be used to control the brightness of the white light-emitting component. Optionally, after obtaining the luminous data of the color light-emitting component, the luminous data of the color light-emitting component can be weighted to obtain the luminous data of the white light-emitting component. Alternatively, a certain luminous data from the luminous data of the color light-emitting component can be selected as the luminous data of the white light-emitting component. For example, the minimum luminous data among the luminous data of the color light-emitting component can be used as the luminous data of the white light-emitting component.

[0077] Specifically, for a display pixel in a display device, after obtaining the emission data of the color light-emitting element in the display pixel, the emission data of the white light-emitting element in the display pixel can be obtained based on the emission data of the color light-emitting element in the display pixel. Using the same method, the emission data of the color light-emitting element and the emission data of the white light-emitting element in each display pixel in the display device can be obtained.

[0078] Step 206: Obtain display pixel data based on the luminescence data of the color light-emitting element and the luminescence data of the white light-emitting element. The display pixel data can be used to control the luminescence brightness of the color light-emitting element and the white light-emitting element in the display pixel. Specifically, the display pixel data for the display pixel can be obtained based on the luminescence data of the color light-emitting element and the luminescence data of the white light-emitting element in the display pixel.

[0079] In step 208 , the display pixel data is sent to each display pixel.

[0080] Specifically, after obtaining the display pixel data of each display pixel, each display pixel data can first be converted into a different driving current, and then each driving current is sent to the corresponding display pixel. The driving current is used to drive the color light-emitting elements and white light-emitting elements in the display pixel to emit light.

[0081] In this embodiment, by acquiring the emission data of the colored light-emitting components, deriving the emission data of the white light-emitting components based on the emission data of the colored light-emitting components, and then deriving the display pixel data based on the emission data of the colored light-emitting components and the emission data of the white light-emitting components, and then transmitting the display pixel data to each display pixel, the display device in any of the above embodiments can be effectively controlled to emit light normally, thereby ensuring the lighting effect of the display device.

[0082] In one embodiment, each display pixel of the display device includes a red light-emitting element, a green light-emitting element, a blue light-emitting element, and a white light-emitting element. As shown in FIG. 5 , step 204 includes step 302 and step 304 .

[0083] Step 302 : Compare the luminous data of the red light emitting component, the green light emitting component, and the blue light emitting component to obtain the minimum luminous data.

[0084] In this embodiment, the color light-emitting parts include red light-emitting parts, green light-emitting parts and blue light-emitting parts. Specifically, after obtaining the light-emitting data of the red light-emitting part, the light-emitting data of the green light-emitting part and the light-emitting data of the blue light-emitting part, the minimum value is obtained by comparing the sizes of the light-emitting data of the three color light-emitting parts, and the minimum value is used as the minimum light-emitting data.

[0085] Step 304: Use the minimum luminous data as the luminous data of the white luminous element.

[0086] Then, display pixel data is obtained according to the light emitting data of the color light emitting elements and the light emitting data of the white light emitting elements, and the display pixel data is sent to each display pixel.

[0087] In this embodiment, by comparing the sizes of the luminous data of the red light-emitting component, the green light-emitting component and the blue light-emitting component, the minimum luminous data is obtained, and the minimum luminous data is used as the luminous data of the white light-emitting component. This can effectively control the normal luminescence of the white light-emitting component in the display pixel, improve the color rendering index of the white light, and ensure the display effect.

[0088] In one embodiment, as shown in FIG. 6 , after step 302 and before step 206 , the method for controlling the display device further includes step 402 .

[0089] Step 402: Update the luminous data of the red light-emitting component, the green light-emitting component, and the blue light-emitting component according to the minimum luminous data.

[0090] Specifically, the minimum luminescence data can be subtracted from the luminescence data of the red, green, and blue light-emitting components to obtain the final luminescence data of the red, green, and blue light-emitting components. Since the red, green, and blue light-emitting components can emit white light when mixed, after subtracting the minimum luminescence data from the luminescence data of the red, green, and blue light-emitting components, the luminescence data of the light-emitting components corresponding to the minimum luminescence data will become 0, resulting in the red, green, and blue light-emitting components being unable to mix and emit white light. This can ensure that the pure color light portion of the color is emitted exclusively by the red, green, and blue light-emitting components, and the white light portion of the color is emitted exclusively by the white light-emitting components, thereby improving the luminescence efficiency of the display device.

[0091] In addition, when each display pixel of the display device includes a white light-emitting element and one of the red, green, and blue light-emitting elements, and three adjacent display pixels include a group of color light-emitting elements, or when each display pixel of the display device includes a white light-emitting element and two of the red, green, and blue light-emitting elements, and three adjacent display pixels include two groups of color light-emitting elements, for each group of color light-emitting elements, first, the minimum light-emitting data can be obtained by comparing the light-emitting data of the red, green, and blue light-emitting elements in the group, and then the minimum light-emitting data is subtracted from the light-emitting data of the red, green, and blue light-emitting elements in the group to obtain the final light-emitting data of the red, green, and blue light-emitting elements. The minimum light-emitting data can then be used as the light-emitting data of all white light-emitting elements in the three adjacent display pixels.

[0092] After updating the luminous data of the red, green and blue light-emitting components according to the minimum luminous data, the display pixel data can be obtained according to the luminous data of the white light-emitting component and the updated luminous data of the red, green and blue light-emitting components, and then the display pixel data can be sent to each display pixel.

[0093] In this embodiment, by updating the luminous data of the red light-emitting component, the green light-emitting component and the blue light-emitting component according to the minimum luminous data, it can be achieved that the pure color light portion in the color is exclusively emitted by the red light-emitting component, the green light-emitting component and the blue light-emitting component, and the white light portion in the color is exclusively emitted by the white light-emitting component, thereby further improving the luminous efficiency of the display device and ensuring the display effect of the display screen.

[0094] In one embodiment, each display pixel of the display device includes a white light-emitting element and one of a red light-emitting element, a green light-emitting element, and a blue light-emitting element, and three adjacent display pixels include a group of color light-emitting elements. Alternatively, each display pixel of the display device includes a white light-emitting element and two of a red light-emitting element, a green light-emitting element, and a blue light-emitting element, and three adjacent display pixels include two groups of color light-emitting elements. As shown in FIG7 , step 202 includes steps 502 and 504.

[0095] Step 502: Acquire initial light emitting data of the color light emitting element in each display pixel.

[0096] The initial light emitting data of the color light emitting element may be used to control the brightness of the light emitted by the color light emitting element.

[0097] Optionally, initial luminescence data for the color light-emitting element in each display pixel can be obtained based on video data input by the user. The video data input by the user can represent a target video image, and each pixel in the target video image can correspond one-to-one to each display pixel in the display device. Furthermore, the video data includes color information for each display pixel, and initial luminescence data for the color light-emitting element in each display pixel can be obtained based on the color information of each display pixel.

[0098] Step 504 : performing weighted calculation based on the initial luminous data of the color luminous elements in the current pixel and the pixels adjacent to the current pixel to obtain the luminous data of the color luminous element in the current pixel.

[0099] In order to avoid losing the color information in the target video image, a display pixel can be randomly selected as the current pixel first, and then a weighted calculation is performed based on the initial luminous data of the color light-emitting components in the adjacent pixels of the current pixel to obtain the luminous data of the color light-emitting components in the current pixel. Among them, the adjacent pixels of the current pixel may include the display pixel located above the current pixel, the display pixel located below the current pixel, the display pixel located to the left of the current pixel, and the display pixel located to the right of the current pixel. For example, as shown in Figure 2, each grid in the figure can represent a display pixel, and each display pixel can be represented by the horizontal axis (a1) and the vertical axis (1-12). When the three adjacent pixels include a group of color light-emitting components, if pixel b3 is selected as the current pixel, then pixel b2, pixel a3, pixel b4, and pixel c3 can be used as the adjacent pixels of pixel b3. Then, the luminous data of the red (R) light emitting element in pixel b3 can be obtained by weighted calculation based on the luminous data of the blue (B) light emitting element in pixel b2, the luminous data of the blue (B) light emitting element in pixel a3, the luminous data of the green (G) light emitting element in pixel b4, and the luminous data of the green (G) light emitting element in pixel c3. Those skilled in the art can set the weights as needed to ensure the display effect of the display screen.

[0100] Furthermore, after performing a weighted calculation based on the initial emission data of the colored light-emitting elements in the current pixel and its neighboring pixels to obtain the emission data of the colored light-emitting element in the current pixel, the emission data of the white light-emitting element can be obtained based on the emission data of the colored light-emitting element. For specific steps, refer to steps 302 and 304 in the above embodiment. Display pixel data is then obtained based on the emission data of the colored light-emitting elements and the emission data of the white light-emitting element, and the display pixel data is sent to each display pixel.

[0101] In this embodiment, the initial luminous data of the color light-emitting components in each display pixel is obtained, and weighted calculation is performed based on the initial luminous data of the color light-emitting components in the current pixel and the adjacent pixels of the current pixel to obtain the luminous data of the color light-emitting components in the current pixel. In this way, when three adjacent pixels share one or two groups of color light-emitting components, the color information in the original video image will not be lost, thereby ensuring the display effect of the display screen.

[0102] In order to facilitate a better understanding of the above-mentioned display device and the control method of the display device, a more detailed specific embodiment is provided below for illustration.

[0103] As shown in Figure 8, traditional color LED displays utilize the principle of three primary colors, employing a mixture of RGB (red, green, and blue) LED elements to generate a virtually infinite array of colors. RGB LED elements have significantly lower luminous efficiency than white LED elements, resulting in high power consumption and significant heat generation. Furthermore, the white light produced by these elements is less natural than the natural color of the screen, significantly distorting the colors of objects against the white background. Furthermore, since the human eye's resolution for color is much lower than its resolution for brightness, and white light contributes the majority of the brightness in a video source, traditional display technology utilizes RGB LED elements for each pixel, resulting in a less-than-ideal cost-effectiveness. Therefore, to address the high power consumption, white light distortion, and high cost of existing color LED displays, this embodiment provides a display device that utilizes red, green, and blue light elements as a group of color light elements. As shown in Figure 1, each display pixel in the display device can include a white light element and a group of color light elements. Alternatively, multiple display pixels can share one or two groups of color light elements. For example, as shown in Figure 2, three adjacent display pixels can share a group of color light elements. As shown in FIG3 , three adjacent display pixels may also share two groups of color light-emitting elements.

[0104] It is understood that when each display pixel includes a white light-emitting element and a group of multi-color light-emitting elements, the number of white light-emitting elements in the display device is equal to the number of light-emitting elements of any one color among the multi-color light-emitting elements. When multiple display pixels share one or two groups of multi-color light-emitting elements, the number of light-emitting elements of any one color among the multi-color light-emitting elements is less than the number of white light-emitting elements.

[0105] Furthermore, since the luminous efficiency of white LEDs is typically around 150 lm / W, while that of colored LEDs is typically less than 40 lm / W, and the luminous efficiency of fine-pitch LEDs is significantly lower, the luminous efficiency of white LEDs is typically 3 to 10 times higher than that of colored LEDs. In typical video images, there are very few pixels with pure color tones (100% color saturation), and the vast majority of pixels contain white components, especially when displaying text. Consequently, existing LED color displays consume high power and are prone to white light distortion. However, the display device in this embodiment includes a white LED in each display pixel, which is dedicated to emitting white light. This not only reduces the power consumption of the display device but also avoids white light distortion. Furthermore, since the display device in this embodiment has fewer colored LEDs, the driving current for each LED is increased. This approach also improves the luminous efficiency of the LEDs, and in turn, reduces overall power consumption.

[0106] Furthermore, the color rendering index of white light produced by mixing the three primary colors (red, green, and blue) is generally below 70. Commercially available white light-emitting devices typically have a color rendering index above 80, and with special requirements, can reach a color rendering index above 95, which is unattainable with the three-primary color scheme. The display device of this embodiment significantly improves the color rendering index of white light, while also enriching the spectrum and providing a better sensory experience for the human eye. Furthermore, since the human eye's color resolution is typically only one-quarter of its luminance resolution, current computer video encoding and digital television transmission standards use only about one-quarter the luminance data for color data. Therefore, even if the color resolution on a display screen is displayed at the same luminance resolution, true color high-resolution video cannot be achieved. Therefore, in cost-sensitive situations, the display device of this embodiment can reduce the number of color light-emitting devices to one-third. Thus, while three pixels previously required nine color light-emitting devices, the display device of this embodiment only requires three or six to achieve a similar display resolution. This reduces the cost of light-emitting devices by at least one-third.

[0107] In addition, this embodiment further provides a control method for the display device described above. Since the compression and transmission of video signals are generally not in RGB format, but in color difference data, according to existing digital display technology, the color difference data needs to be converted into RGB format for display. For the convenience of explanation, this example uses an RGB data source (corresponding to the video data mentioned above) as an example, and assumes that the RGB data source is 8-bit binary (i.e., 24-bit color). For the sake of simplicity, gamma correction is not considered here. The method specifically includes:

[0108] For each display pixel, the RGB values ​​are first compared (corresponding to the comparison of the red, green, and blue light-emitting components mentioned above). The smallest value is used as the light-emitting data for the white light-emitting component. The smallest value is then subtracted from the RGB value to obtain the new RGB light-emitting data. The light-emitting data corresponding to the original smallest value is set to 0, thus obtaining the display pixel data of the three primary colors (RGB) plus white.

[0109] When three adjacent pixels share a single set of RGB, the number of each color light-emitting element (one of the RGB) is only 1 / 3 of the number of white light-emitting elements, so the luminous data of each color light-emitting element must correspond to the original three pixels. To avoid losing the original color information, the luminous data of each color light-emitting element will be weighted and calculated based on the color information of the four display pixels above, below, left, and right. In this way, the luminous data of each color light-emitting element can be obtained. Similarly, when three adjacent pixels share two sets of RGB, the luminous data of each color light-emitting element can also be weighted and calculated based on the color information of the four display pixels above, below, left, and right.

[0110] The display device and the control method of the display device in this embodiment obtain the luminescence data of the colored light-emitting parts, obtain the luminescence data of the white light-emitting parts based on the luminescence data of the colored light-emitting parts, obtain the display pixel data based on the luminescence data of the colored light-emitting parts and the luminescence data of the white light-emitting parts, and send the display pixel data to each display pixel, so as to effectively control the luminescence of the display device and further ensure the display effect of the display device.
