[0041] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts are within the scope of protection of this application.

[0042] Please refer to Figure 1, which is a schematic diagram of the structure of an electronic device provided in an embodiment of the present application. This embodiment of the present application provides an electronic device 1, which can be a device with a display function, such as a television, a mobile phone, a computer, an augmented reality device (AR), a virtual reality device (VR), etc.

[0043] For example, the electronic device 1 may include a display device 10 and a housing 20 .

[0044] The display device 10 is a main component of the electronic device 1. Taking a liquid crystal display device as an example, please refer to FIG1 and FIG2 , which is a schematic diagram of the structure of the display device provided in an embodiment of the present application. The display device 10 may include a display module 100 and a backlight module 200. The display module 100 is a structure including an array substrate, a color filter substrate, and a liquid crystal layer sandwiched between the two. The backlight module 200 provides a backlight source for the display module 100, and the backlight module 200 cooperates with the display module 100 to realize picture display. The display principle of the display device 10 is: under the action of an electric field, the arrangement direction of the liquid crystal molecules changes, so that the transmittance of the backlight source changes (modulation), completing the electrical to optical conversion, and then using the different excitations of the R, G, and B primary color signals, through the red, green, and blue primary color filters, completing the color reproduction in the time domain and spatial domain.

[0045] The housing 20 is used to carry the display device 10 and encapsulate components of the display device 10 such as wires, so as to improve the aesthetics of the electronic device 1 .

[0046] With the advancement of technology and the increasing demand for eye protection in display devices, major manufacturers have invested in research related to display eye protection. Numerous studies have examined the effects of artificial light on biological characteristics, with results demonstrating that artificial light significantly disrupts human circadian rhythms. For example, enhanced blue light stimulation can increase melatonin production, thereby suppressing sleepiness.

[0047] Consumers generally believe that natural light is the healthiest and most eye-protecting light source. Therefore, there is an urgent need to design a display device that simulates the natural spectrum to meet people's growing demand for eye protection.

[0048] In order to reduce the occurrence of the above problems, the embodiment of the present application improves the display module 100 and the backlight module 200, which will be described below with reference to the accompanying drawings.

[0049] For example, please refer to FIG3 in conjunction with FIG1 and FIG2 , which is a schematic diagram of the partial structure of the display module provided in an embodiment of the present application. The display module 100 includes a plurality of sub-pixels 110. It is understandable that the plurality of sub-pixels 110 may be a structure including a color filter, liquid crystal molecules, and pixel electrodes, and the pixel electrodes and common electrodes act together on the liquid crystal molecules to turn the liquid crystal molecules to turn the sub-pixels 110 on or off. Among them, at least one sub-pixel 110 includes a color-resistance sub-pixel 112 and a transparent sub-pixel 114. Among them, the color-resistance sub-pixel 112 is one of a red sub-pixel, a blue sub-pixel, and a green sub-pixel, and the plurality of sub-pixels 110 may include three types of sub-pixels: red sub-pixels, blue sub-pixels, and green sub-pixels. The transparent sub-pixel 114 is a sub-pixel that does not have a color resistance and allows light to pass directly through. The function of the transparent sub-pixel 114 is to transmit various spectral components of the full-spectrum backlight, thereby achieving full-spectrum display.

[0050] The display module 100 has a first display mode. In this mode, both the color-resistance sub-pixels 112 and the transparent sub-pixels 114 are turned on to transmit light. This first display mode can also be referred to as full-spectrum display. In this display mode, the backlight source is not limited to transmitting light through the color-resistance sub-pixels 112, resulting in higher light purity. Instead, the backlight source can transmit light through both the color-resistance sub-pixels 112 and the transparent sub-pixels 114 simultaneously, making the overall color display less extreme. This means that the backlight source light is mixed in different ways to achieve a full-spectrum eye-protection display, simulating natural light display and reducing irritation to the user's eyes.

[0051] It should be noted that a sub-pixel is turned on when the driving circuit deflects the liquid crystal molecules by a certain angle, allowing light to pass through. Conversely, a sub-pixel is turned off when the liquid crystal molecules are closed, preventing light from passing through.

[0052] In the display module 100 provided in the embodiment of the present application, by re-dividing the existing color-resistance sub-pixels into a structure of color-resistance sub-pixels 112 plus transparent sub-pixels 114, the light source can be controlled to simultaneously pass through the color-resistance sub-pixels 112 and the transparent sub-pixels 114 in the first display mode, thereby reducing the extreme effects of the overall display color and achieving a display effect that simulates the natural full spectrum, thereby meeting the user's eye protection needs for the display device 10.

[0053] The area ratio of the transparent sub-pixel 114 to the color-resistance sub-pixel 112 is within a range of 0.1 to 10. Specifically, the area ratio of the transparent sub-pixel 114 to the color-resistance sub-pixel 112 can be 0.1, meaning the transparent sub-pixel 114 has a smaller area, 0.1 times the area of ​​the color-resistance sub-pixel 112. The area ratio of the transparent sub-pixel 114 to the color-resistance sub-pixel 112 can also be 1, meaning the transparent sub-pixel 114 and the color-resistance sub-pixel 112 are equal. The area ratio of the transparent sub-pixel 114 to the color-resistance sub-pixel 112 can also be 10, meaning the transparent sub-pixel 114 has a larger area than the color-resistance sub-pixel 112.

[0054] It should be noted that, because high color gamut display and simulating natural spectrum display are conflicting indicators, the area ratio of the transparent sub-pixel 114 to the color-resistance sub-pixel 112 is set within a relatively wide range. The area ratio of the transparent sub-pixel 114 to the color-resistance sub-pixel 112 can be designed based on the usage scenario of the electronic device 1. For example, for electronic devices 1 used indoors, frequently used at night, or frequently displaying text information, the area ratio of the transparent sub-pixel 114 to the color-resistance sub-pixel 112 can be greater than 1, thereby simulating the display effect of natural light and achieving eye protection. For another example, for electronic devices 1 used outdoors, frequently used during the day, or frequently displaying color images, the area ratio of the transparent sub-pixel 114 to the color-resistance sub-pixel 112 can be less than or equal to 1. Because the ambient light is brighter, the electronic device 1 requires higher color saturation to match the ambient light, both ensuring clearer viewing for the user and providing eye protection.

[0055] It should be noted that, for at least one of the multiple sub-pixels 110, including a color-resistance sub-pixel 112 and a transparent sub-pixel 114, the number of sub-pixels 110 including the color-resistance sub-pixel 112 and the transparent sub-pixel 114 can be set based on the scenario in which the electronic device 1 is located, or in other words, the scenarios in which the electronic device 1 is frequently used. For example, for an electronic device 1 used indoors, frequently used at night, or frequently displaying text information, the multiple sub-pixels 110 can be configured to include both the color-resistance sub-pixel 112 and the transparent sub-pixel 114, and the ratio of the area of ​​the transparent sub-pixel 114 to the color-resistance sub-pixel 112 can be greater than 1. This can simulate the display effect of natural light and achieve eye-protection display.

[0056] For another example, for electronic devices 1 used outdoors, often during the day, or that frequently display color images, the multiple sub-pixels 110 can be configured to include both color-resistance sub-pixels 112 and transparent sub-pixels 114. In this case, the area ratio of the transparent sub-pixels 114 to the color-resistance sub-pixels 112 is not restricted. Alternatively, a small portion of the multiple sub-pixels 110 can be configured to include both color-resistance sub-pixels 112 and transparent sub-pixels 114, while the remaining sub-pixels 110 are all color-resistance sub-pixels. In this case, the area ratio of the transparent sub-pixels 114 to the color-resistance sub-pixels 112 is also not restricted. Because ambient light is brighter, electronic device 1 requires higher color saturation. Setting the overall ratio of color-resistance sub-pixels 112 to be higher than that of transparent sub-pixels 114 allows for better viewing and better eye protection.

[0057] This embodiment of the present application is described using an example in which each of the plurality of sub-pixels 110 includes a color-resistance sub-pixel 112 and a transparent sub-pixel 114. In the first display mode, the color-resistance sub-pixels 112 and the transparent sub-pixels 114 in all sub-pixels 110 are turned on to transmit light, thereby mixing the light and reducing the high saturation displayed by the electronic device 1, simulating a natural light display, and thus achieving an eye-protection display.

[0058] Exemplarily, the display module 100 also has a second display mode. In the second display mode, the color-resistance sub-pixels 112 in all sub-pixels 110 are turned on to transmit light, and the transparent sub-pixels 114 are turned off. The color display is purer, thereby obtaining a display effect with a higher color gamut or higher saturation. Therefore, the second display mode can also be called a high color gamut display mode.

[0059] The display module 100 or the electronic device 1 can adopt different display modes in different usage scenarios. When the display module 100 changes the usage scenario, or when the ambient light changes significantly in the same usage scenario, the display module 100 can dynamically switch between the first display mode and the second display mode, thereby satisfying the dynamic switchable function of high color gamut display and full spectrum display in display effect, which can broaden the application scenarios of the electronic device 1 and improve the competitiveness of the electronic device 1.

[0060] The switching of the display modes can be achieved according to other components of the display module 100 .

[0061] For example, referring to Figures 1 to 3 and Figure 4, Figure 4 is a schematic cross-sectional view of the display module shown in Figure 3 along the line AA. The display module 100 further includes a drive layer 120, which is disposed on one side of the plurality of sub-pixels 110. It is understood that the drive layer 120 can be disposed on one side of the array substrate. The drive layer 120 applies voltage to the pixel electrodes and the common electrode, thereby controlling the liquid crystal molecules to turn on or off the sub-pixels 110.

[0062] The driving layer 120 includes a first switch 122 and a second switch 124. The first switch 122 is provided corresponding to the color-resistance sub-pixel 112 to turn the color-resistance sub-pixel 112 on or off. Specifically, the first switch 122 applies a voltage to the pixel electrode, which in turn acts in conjunction with the common electrode to redirect the liquid crystal molecules, thereby allowing light to pass through the color-resistance sub-pixel 112 or preventing light from passing through the color-resistance sub-pixel 112, thereby turning the color-resistance sub-pixel 112 on or off.

[0063] Correspondingly, the second switch 124 is set corresponding to the transparent sub-pixel 114 to turn on or off the transparent sub-pixel 114. That is, the second switch 124 applies voltage to the pixel electrode, and the pixel electrode and the common electrode act together to turn the liquid crystal molecules, thereby allowing light to pass through the transparent sub-pixel 114 or preventing light from passing through the transparent sub-pixel 114, thereby turning the transparent sub-pixel 114 on or off.

[0064] Exemplarily, the first switch 122 and the second switch 124 are both thin-film transistors, which are semiconductor switching devices. A semiconductor switching device is configured for each color-resistance sub-pixel 112 and each transparent sub-pixel 114, so that each color-resistance sub-pixel 112 and each transparent sub-pixel 114 can be directly controlled by a dot pulse, so that each node is independent of each other and can be continuously controlled, which can improve the response speed of the display module 100 and also accurately control the display grayscale.

[0065] Among them, the drain of the first switch 122 is connected to the source of the second switch 124. It should be noted that the drain of the first switch 122 is usually connected to the pixel electrode, and the pixel electrode of the color-resistance sub-pixel 112 is used as the source of the transparent sub-pixel 114 corresponding to the second switch 124. The pixel electrode of the transparent sub-pixel 114 is similar to the pixel electrode of the color-resistance sub-pixel 112, so that a controllable transparent sub-pixel 114 area can be achieved. During manufacturing, the pixel electrode of the color-resistance sub-pixel 112 is integrated with the drain of the first switch 122 and the source of the second switch 124, that is, they are manufactured together, which can simplify the manufacturing process and improve manufacturing efficiency. Similarly, the pixel electrode of the transparent sub-pixel 114 is connected to the drain of the second switch 124. During manufacturing, the pixel electrode of the transparent sub-pixel 114 can also be integrated with the drain of the second switch 124.

[0066] Each sub-pixel 110 in at least one row of sub-pixels 110 includes a color-resistance sub-pixel 112 and a transparent sub-pixel 114. The driving layer 120 further includes at least one conversion line 126. Each conversion line 126 is connected to a second switch 124 corresponding to a transparent sub-pixel 114 in a row of sub-pixels 110, thereby enabling on / off control of the transparent sub-pixels 114 in a row of sub-pixels 110.

[0067] For example, each of the sub-pixels 110 in the embodiment of the present application includes a color-resistance sub-pixel 112 and a transparent sub-pixel 114. Therefore, the driving layer 120 includes a plurality of conversion lines 126, each of which is connected to a row of second switches 124. The transparent sub-pixels 114 can be controlled by a single row, multiple rows, or a full-screen unified switch control, with the number of control circuits configured being different. This allows for dynamic switching between the first display mode and the second display mode, allowing the display module 100 to adapt to different scene changes.

[0068] In the display module 100 provided in the embodiment of the present application, by re-dividing the existing color-resistance sub-pixels into a structure of color-resistance sub-pixels 112 plus transparent sub-pixels 114, the light source can be controlled to simultaneously pass through the color-resistance sub-pixels 112 and the transparent sub-pixels 114 in the first display mode, thereby reducing the extreme effects of the overall display color and achieving a display effect that simulates the natural full spectrum, thereby meeting the user's eye protection needs for the display device 10.

[0069] Corresponding improvements have also been made to the backlight module 200 .

[0070] In traditional backlighting, LED (Light-Emitting Diode) light sources are point light sources with a narrow spectrum, with a peak wavelength between 450nm and 460nm. The white light spectrum formed after exciting the phosphor also has a large number of spectral omissions, which is quite different from the sunlight spectrum. The optimal visual requirement of the human eye is a color temperature range of 2500K to 6500K. The special structure of the human eye and the long-term living environment of humans determine that the human eye has the highest perception when reading and observing in sunlight. In order to make the human eye feel comfortable in a certain lighting environment, its emission spectrum needs to be close to the sunlight spectrum, that is, the spectrum with a color rendering index close to 100.

[0071] Therefore, in order to match the simulated full-spectrum display of the display module 100 , corresponding improvements are also made to the light source of the backlight module 200 .

[0072] Please refer to Figures 1 to 4 and refer to Figures 5 and 6. Figure 5 is a schematic diagram of the first structure of the backlight module provided in an embodiment of the present application, and Figure 6 is a schematic diagram of the second structure of the backlight module provided in an embodiment of the present application. Exemplarily, the backlight module 200 includes a lamp bead 210, and the lamp bead 210 includes a blue light chip 212 and a fluorescent glue 214. The peak wavelength range of the spectrum emitted by the blue light chip 212 is 440nm to 450nm. The fluorescent glue 214 is arranged on the outside of the blue light chip 212, for example, it can surround the blue light chip 212. As shown in Figure 5, the fluorescent glue 214 can surround one blue light chip 212; as shown in Figure 6, the fluorescent glue 214 can also include the outside of multiple blue light chips 212, which is not specifically limited here. The fluorescent glue 214 can include a first fluorescent material, a second fluorescent material, a third fluorescent material and silica gel. The first fluorescent material emits light with a peak wavelength of 485nm to 500nm under the stimulation of light emitted by the blue light chip 212. The second fluorescent material emits light with a peak wavelength of 525nm to 535nm under the stimulation of light emitted by the blue light chip 212. The third fluorescent material emits light with a peak wavelength of 650nm to 665nm under the stimulation of light emitted by the blue light chip 212. Under the stimulation of light emitted by the blue light chip 212, the fluorescent glue 214 causes the color temperature of the light emitted by the lamp bead 210 to range from 2600K to 6500K, thereby meeting the optimal visual requirements of the human eye. In conjunction with the display module 100, this simulates a full-spectrum display, achieving eye protection.

[0073] Exemplarily, the first fluorescent material is a mixture of nitrogen oxide and silicate, specifically, a mixture of nitrogen oxide and silicate BaSi2O2N2:Eu:. The light emitted by the first fluorescent material under the excitation of the light emitted by the blue light chip 212 is cyan.

[0074] Exemplarily, the second fluorescent material is a mixture of green powder and YAG fluorescent powder. Specifically, the green powder is Ga-YAG:. The light emitted by the second fluorescent material under the excitation of the light emitted by the blue light chip 212 is green.

[0075] Exemplarily, the third fluorescent material is a nitride, specifically, the nitride is M 2x Si5N8:Eu x 2+ or CaAlSiN3:Eu 2+ , the light emitted by the third fluorescent material under the stimulation of the light emitted by the blue light chip 212 is red.

[0076] Exemplarily, the blue chip 212 is a flip chip, which is a pinless structure generally containing a circuit unit and is designed to be electrically and mechanically connected to a circuit through an appropriate number of solder balls (covered with conductive adhesive) located on its surface.

[0077] Please refer to Figures 1 to 6 and Figure 7, which is a schematic diagram of the spectrum distribution under different display modes provided by the embodiment of the present application. In order to verify the display effect of the display device 10 or electronic device 1 of the embodiment of the present application, a simulation experiment was carried out. Among them, the K3 curve is the spectral distribution of the full-spectrum backlight, the K2 curve is the second display mode, that is, high color gamut display, and the white light spectrum distribution emitted by the screen when the transparent sub-pixel 114 is turned off, and the K1 curve is the first display mode, that is, full-spectrum display, and the white light spectrum distribution emitted by the screen after the transparent sub-pixel 114 is turned on. It can be seen that by adjusting the area ratio of the transparent sub-pixel 114 to the color-resistance sub-pixel 112, the degree of fit between the spectral components emitted by the screen in the first display mode and the backlight source, as well as the degree of proximity to the natural spectral components, can be adjusted. Therefore, through an innovative sub-pixel design, full-spectrum display technology can be realized, that is, an electronic device 1 that simulates the spectral components of natural light is obtained.

[0078] In the display module 100, display device 10, and electronic device 1 provided in the embodiments of the present application, by re-dividing the existing color-resistance sub-pixels into a structure of color-resistance sub-pixels 112 and transparent sub-pixels 114, the light source can be controlled to simultaneously transmit through the color-resistance sub-pixels 112 and transparent sub-pixels 114 in the first display mode, thereby reducing the extreme effects of the overall displayed color and achieving a display effect that simulates a natural full spectrum, thereby meeting the user's eye protection needs for the display device 10. Specifically, full-spectrum backlight technology is introduced to simulate the optimal visual color temperature of the human eye, and in conjunction with the display module 100, simulates a natural full-spectrum display to achieve the purpose of eye protection.
