[0002] At present, in some special fields, such as modern aviation, the reliability and adaptability of display technology are crucial. Especially in the cockpit, with the complexity of flight missions and the diversity of environmental conditions, the display screen in the cockpit must have night vision compatibility to ensure that pilots can clearly obtain key information in low light or night conditions.

[0003] Micro LED (Micro Light Emitting Diode) is a new generation of display technology, which has attracted much attention due to its unique self-luminous properties. Compared with traditional LCD (Liquid Crystal Display) and OLED (Organic Light Emitting Diode) display technologies, Micro LED has a higher color gamut, better brightness performance and longer service life. These characteristics make Micro LED displays perform better in extreme environments and can provide a clear visual experience in strong sunlight and low light environments.

[0004] However, despite the many advantages of Micro LED technology, there are still some technical challenges in practical applications. For example, how to achieve effective color management and brightness adjustment to ensure that Micro LED displays can provide sufficient readability without glare in night vision mode is an urgent problem to be solved. Summary of the invention

[0032] The following disclosure provides many different embodiments or examples for implementing the different features of the provided subject matter. The specific examples of components and arrangements are described below. Of course, these are only examples and are not intended to be restrictive. In the present disclosure, references to forming or arranging a first feature on or above a second feature may include embodiments in which the first feature and the second feature are formed or arranged to be in direct contact, and may also include embodiments in which additional features may be formed or arranged between the first feature and the second feature so that the first feature and the second feature may not be in direct contact. In addition, the present disclosure may repeat reference numerals and / or letters in various examples. This repetition is for the purpose of simplicity and clarity and is not intended to limit the relationship between the various embodiments and / or configurations discussed.

[0033] The following is a detailed discussion of embodiments of the present disclosure. However, it should be understood that the present disclosure provides many applicable concepts that can be embodied in a variety of specific environments. The specific embodiments discussed are merely illustrative and do not limit the scope of the present disclosure.

[0034] Figure 1 A pixel structure provided according to the present disclosure is shown. Figure 1 As shown, the pixel structure includes: a plurality of repeating units, each repeating unit includes: an orange sub-pixel, a red sub-pixel, a green sub-pixel and a blue sub-pixel.

[0035] It should be noted that the pixel structure shown in the embodiment of the present disclosure is applied to a Micro LED display device. Micro LED is a new type of display technology that uses micron-level light-emitting diodes as display units. Compared with traditional display technologies (such as liquid crystal displays and organic light-emitting diodes), Micro LED has many significant advantages. For example: Micro LED is composed of millions of micro LEDs, each of which is usually at the micron level (generally less than 100 microns). These micro LEDs can emit light individually, thereby achieving high-resolution and high-contrast display effects; unlike LCD, Micro LED does not require a backlight source, and each micro LED can emit light independently, which enables the display to achieve deeper black and higher brightness; Micro LED displays can reach very high brightness levels and are suitable for use under various lighting conditions. At the same time, due to its self-luminous characteristics, the black display is deeper and the contrast is improved; Micro LED can cover a wider color gamut and provide richer color performance, which makes the display of images and videos more vivid and realistic; Micro LED displays usually have a longer service life than OLEDs because they are not easily affected by screen burn-in. In addition, Micro LEDs are also more tolerant to temperature and humidity. Therefore, conducting relevant night vision compatibility research based on Micro LED displays can further leverage the advantages of Micro LED displays and expand their application areas (such as cockpits in aviation or other scenes that require night vision).

[0036] Based on this, the present disclosure provides Figure 1 The pixel structure shown can be applied to a Micro LED display device.

[0037] Specifically, the pixel structure includes: a plurality of repeating units, each repeating unit includes: an orange sub-pixel, a red sub-pixel, a green sub-pixel and a blue sub-pixel. Among them, the wavelength range of the orange light emitted by the orange sub-pixel is: 590nm to 600nm. This pixel structure allows each repeating unit to mix and generate multiple colors through different sub-pixel combinations. And adding an orange sub-pixel can emit orange light, which can play an important role in color mixing. By adjusting the brightness of the orange sub-pixel and the remaining sub-pixels, a variety of colors can be generated to enhance the display effect.

[0038] It should be noted that in the existing RGB (red, green, blue) color model, orange is usually achieved by a combination of red and green. In the pixel structure shown in the embodiment of the present disclosure, the direct introduction of orange sub-pixels can improve the accuracy and richness of colors and reduce color distortion caused by mixing. In low-light environments, orange light is more easily accepted by the eyes than blue and red light, which can reduce visual fatigue. This makes the orange sub-pixel particularly important in night mode or special application scenarios.

[0039] In the night vision display mode, the orange sub-pixel is used to replace the position of the red sub-pixel in the RGB color standard. That is, in the night vision display mode, the orange sub-pixel is displayed according to the data of the red sub-pixel at the corresponding pixel position.

[0040] It should be noted that the RGB color model is a model that generates other colors by combining the three basic colors of red, green and blue with different intensities. In this model, the sub-pixel of each color controls its brightness by adjusting the current to achieve the desired color output. In the pixel structure shown in the embodiment of the present disclosure, in some application scenarios, especially in the night vision display mode, the position of the red sub-pixel in the RGB model is replaced by an orange sub-pixel. This is because orange light is easier to be accepted by the eyes than red light in a night environment, which can reduce visual fatigue, and more importantly, orange light replaces conventional red light, which can meet the night vision requirements and can form clear images at night. This makes it more appropriate to use orange sub-pixels in night vision mode, and the wavelength range of orange light (590nm to 600nm) is similar to that of red light, so visually, orange light can effectively replace red light, that is, in the night vision display mode, the orange sub-pixel is displayed according to the data of the red sub-pixel at the corresponding pixel position. As a result, the following effects can be achieved: in night vision display mode, the brightness of the orange sub-pixel can match the brightness of the red sub-pixel, thereby ensuring that there is no obvious difference in visual effects; the brightness consistency of the entire display can be maintained, and obvious color deviations between different display modes can be avoided as much as possible; and the display can be adaptively adjusted in different usage environments. For example, in night vision mode, the display can protect the user's eyesight while still providing sufficient information display by activating the orange sub-pixel without significantly increasing the overall brightness, thereby achieving night vision compatibility.

[0041] The arrangement of sub-pixels in the pixel structure is now described in detail.

[0042] In a first possible implementation, the repeating unit includes an orange sub-pixel, a red sub-pixel, a green sub-pixel, and a blue sub-pixel, wherein the orange sub-pixel and the red sub-pixel are distributed diagonally, and the blue sub-pixel and the green sub-pixel are distributed diagonally.

[0043] In a second possible implementation, the repeating unit includes four sub-pixel groups, the four sub-pixel groups include two first sub-pixel groups and two second sub-pixel groups; the first sub-pixel group includes a red sub-pixel, a green sub-pixel and a blue sub-pixel; the second sub-pixel group includes an orange sub-pixel, a green sub-pixel and a blue sub-pixel; wherein the two first sub-pixel groups are diagonally distributed, the two second sub-pixel groups are diagonally distributed, and the sub-pixels in each sub-pixel group are arranged in a herringbone shape.

[0044] In the above two possible implementations, the spacings between adjacent repeating units are the same, and within the repeating units, the spacings between adjacent sub-pixels are the same.

[0045] It should be noted that in the first possible implementation, there are 4 LED lights in one repeating unit (i.e., one orange sub-pixel, one red sub-pixel, one green sub-pixel, and one blue sub-pixel), and the 4 LED lights can be independently driven for display according to different usage scenarios to achieve usage requirements; and in order to meet the requirements of night vision indicators, LED lights of different wavelengths are selected for verification, and finally an LED light with a wavelength of 595±5nm is selected as the LED light of the orange sub-pixel. After the LED light is selected, it is necessary to evaluate indicators such as uniformity, brightness, and contrast to meet usage requirements. Therefore, based on this, the pixels are rearranged on the basis of the conventional pixel arrangement, such as Figure 1 As shown, every 4 LED lamps serve as a repeating unit. In each repeating unit, different LED lamps are turned on and driven according to usage requirements, and are symmetrically and evenly arranged on the display substrate as a whole. The spacing between LED lamps and the spacing between each repeating unit are the same. At the same time, in order to improve the uniformity of light output and further enhance the display effect, the red and orange LED lamps cannot be adjacent, so the orange sub-pixels and the red sub-pixels are diagonally distributed, and the blue sub-pixels and the green sub-pixels are diagonally distributed.

[0046] Specifically, by distributing the red and orange LED lights diagonally, the light can be distributed more evenly. The diagonal arrangement separates the red light source and the orange light source in space, which can better avoid the problem of excessive or low light intensity in local areas, thereby improving the overall light uniformity. The light uniformity directly affects the user's viewing experience. If the display has uneven brightness in certain areas, it may cause visual fatigue or discomfort. The diagonal distribution design can improve the overall visual comfort, reduce the sudden change of color and brightness, and make the user feel more natural and comfortable when watching. And by improving the uniformity of light, the display can reproduce various colors more accurately, especially when displaying high-contrast images. The diagonal arrangement design allows each color of light to blend better, improving the overall color performance.

[0047] In the second possible implementation, Figure 2 As shown, the repeating unit includes four sub-pixel groups, and the four sub-pixel groups include two first sub-pixel groups and two second sub-pixel groups; the first sub-pixel group includes a red sub-pixel, a green sub-pixel and a blue sub-pixel; the second sub-pixel group includes an orange sub-pixel, a green sub-pixel and a blue sub-pixel; wherein the two first sub-pixel groups are diagonally distributed, the two second sub-pixel groups are diagonally distributed, and the sub-pixels in each sub-pixel group are arranged in a herringbone shape.

[0048] That is to say, each sub-pixel group adopts a design of 3 LED lights, and two sub-pixel groups are RGB, two sub-pixel groups are OGB, and the repeating unit (also called mother pixel) is composed of four sub-pixel groups (two RGB, two OGB). Figure 2 As shown, the sub-pixels in each sub-pixel group are arranged in a herringbone shape, and the red sub-pixels and orange sub-pixels in the repeating unit are distributed diagonally (which is a natural result of the two first sub-pixel groups being distributed diagonally and the two second sub-pixel groups being distributed diagonally). Therefore, while maintaining the requirements of uniformity, brightness, contrast and other indicators, the number of LED lamps can be reduced, and the power consumption and cost can be reduced.

[0049] It should be noted that the two first sub-pixel groups are distributed in a diagonal manner, and the two second sub-pixel groups are distributed in a diagonal manner to ensure that the red sub-pixels and the orange sub-pixels in the repeating unit are distributed in a diagonal manner, which can effectively avoid color interference. Figure 2 As shown, two groups of first sub-pixel groups ( Figure 2 The upper left corner and Figure 2 The two red sub-pixels in the lower right corner of the figure, and the two second sub-pixel groups ( Figure 2 The upper right corner and Figure 2 The two orange sub-pixels in the lower left corner of the quadrilateral are located at four corners respectively, and the red sub-pixels and the orange sub-pixels are distributed diagonally. Such a layout can reduce the interference between adjacent sub-pixels and ensure that each color of light can emit light independently, thereby improving the overall color accuracy and ensuring that different colors of light can be better integrated visually and avoiding the problem of uneven color mixing.

[0050] Figure 3 A display panel 30 provided according to an embodiment of the present disclosure is shown. Figure 3 The display panel shown includes Figure 1 The pixel structure 10 is shown.

[0051] Figure 4 A display device 40 provided according to an embodiment of the present disclosure is shown, which includes: Figure 3The display panel 30 is shown.

[0052] And if Figure 4 As shown, the display device 40 further includes: a light sensor 50 for detecting the brightness of ambient light;

[0053] The control module 60 is used to control the display mode of the display panel 30 according to the brightness of the detected ambient light. In the first display mode, the red sub-pixel, the green sub-pixel and the blue sub-pixel in the repeating unit are all turned on, and the orange sub-pixel in the repeating unit is turned off; in the second display mode, the orange sub-pixel, the green sub-pixel and the blue sub-pixel in the repeating unit are all turned on, and the red sub-pixel in the repeating unit is turned off. The first display mode is a normal display mode, and the second display mode is a night vision display mode.

[0054] Therefore, in the night vision display mode, the closing of the red sub-pixel helps to achieve imaging of the night vision device while reducing irritation and damage to the eyes, especially in low-light environments. The opening of the orange sub-pixel can provide gentler light, which helps to maintain night vision visibility in dark environments and maintain visual comfort. At the same time, the opening of the green and blue sub-pixels can ensure that the display can still provide the necessary visibility. In the conventional display mode and the night vision display mode, the control module drives each sub-pixel group independently, and can individually control the brightness and opening state of the sub-pixels (LED lights) in the sub-pixel group. Therefore, the output of each sub-pixel can be flexibly adjusted according to display requirements, ambient light conditions and user preferences, which is conducive to switching between different modes during the day and at night.

[0055] With the above Figure 4 Corresponding to the structure of the display device 40 shown in FIG. 4 , a display method is also provided, such as Figure 5 As shown, the method includes:

[0056] Step S101, in a first display mode, controlling the red sub-pixel, the green sub-pixel and the blue sub-pixel in the repeating unit of the display device to be turned on, and controlling the orange sub-pixel in the repeating unit to be turned off;

[0057] Step S102, in the second display mode, the orange sub-pixel, the green sub-pixel and the blue sub-pixel in the repeating unit are all turned on, and the red sub-pixel in the repeating unit is turned off;

[0058] Among them, the first display mode is the normal display mode, and the second display mode is the night vision display mode.

[0059] In the first display mode, the light mixing ratio of the red sub-pixel, green sub-pixel and blue sub-pixel module is the same as the light mixing ratio of the orange sub-pixel, green sub-pixel and blue sub-pixel module in the second display mode.

[0060] It should be noted that in order to control the consistency of light color mixing, the mixing ratio of the four LED lights, red, green, blue and orange, can be mixed according to 3(R):6(G):1(B) in the normal display mode, and can be mixed according to 3(O):6(G):1(B) in the night vision display mode to ensure the light output effect.

[0061] In summary, the pixel structure, display panel, display device and display method shown in the embodiments of the present disclosure mainly adjust the pixels of the Micro LED display screen, add O pixels on the basis of the original RGB, and re-layout the pixels to achieve the required display effect and achieve night vision compatibility; and add a four-light direct display design, and divide the usage scenarios into daytime and nighttime, and adopt the following method: Figure 5 The two independent drive schemes shown in the figure can realize the free and independent switching between the conventional display and the night vision display. In addition, the layout design of the four pixels is redesigned (such as Figure 1 and 2 The pixel structure shown in the embodiment of the present disclosure has high feasibility in technology and process, is easy to mass produce, and can be applied to actual products.

[0062] Moreover, the night vision compatibility research based on Micro LED display is not only an urgent need to improve the display technology of aviation cockpit, but also an important step to promote the landing of this emerging technology in special application fields. Through in-depth research and solving the above technical problems, the future Micro LED display is expected to play a greater role in aviation, military, medical and other fields, further improving the safety and operational efficiency of these fields.
