[0040] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0041] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Features thus defined as "first" and "second" may explicitly or implicitly include one or more features. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0042] Please refer to Figure 1. This embodiment provides a display device, which includes a display panel and a backlight module 3. The display panel includes an array substrate 1 and a color filter substrate 2 stacked together. The backlight module 3 is disposed on the side of the display panel facing away from the color filter substrate 2. The color filter layer is divided into a plurality of pixel units 21 arranged in a periodic repeating pattern. Each pixel unit 21 includes a red sub-pixel 211, a green sub-pixel 212, a purple sub-pixel 213, and a sky blue sub-pixel 214. The array substrate 1 is provided with a pixel driving structure 11 corresponding to each sub-pixel. The backlight module 3 has a plurality of light source components, which are used to provide backlight for the display panel.

[0043] In this embodiment, the pixel driving structure 11 corresponding to the sky-blue sub-pixel 214 is the first pixel driving structure, and the pixel driving structure 11 corresponding to the purple sub-pixel 213 is the second pixel driving structure. The first pixel driving structure is used to control the brightness of the sky-blue sub-pixel 214 transmitted through the first target wavelength light, and the first pixel driving structure is used to control the brightness of the purple sub-pixel 213 transmitted through the second target wavelength light, so that the purple sub-pixel 213 and the sky-blue sub-pixel 214 achieve the purpose of light mixing, and control the pixel chromaticity of the pseudo-blue sub-pixel formed by color mixing. In this embodiment, by replacing the blue sub-pixel in the original pixel unit 21 with two sub-pixels, the purple sub-pixel 213 and the sky-blue sub-pixel 214, for display, the harmful blue light band in the original blue sub-pixel can be avoided, thereby avoiding harmful blue light display, and without affecting the accuracy of the displayed color.

[0044] In some embodiments, the wavelength corresponding to the first target wavelength band is 380nm to 415nm, and the wavelength of the second target wavelength band is 455nm to 500nm. In this embodiment, the purple sub-pixel 213 and the sky blue sub-pixel 214 are mixed to display the original blue sub-pixel, and mixed with the red sub-pixel 211 and the green sub-pixel 212 to display various colors, thereby avoiding the harmful blue light band of 415nm-455nm emitted by the original blue sub-pixel, realizing zero harmful blue light display, and without affecting the accuracy of the displayed color.

[0045] Referring to Figure 2, in some embodiments, the areas of purple sub-pixels 213, sky blue sub-pixels 214, red sub-pixels 211, and green sub-pixels 212 are all the same, and the areas of purple sub-pixels 213, sky blue sub-pixels 214, red sub-pixels 211, and green sub-pixels 212 are arranged at intervals along the X direction; in this embodiment, each sub-pixel in the pixel unit 21 is set to have an equal area in order to improve the uniformity of light mixing among the sub-pixels in the pixel unit 21.

[0046] Referring to Figure 3, in some embodiments, the area of ​​each red sub-pixel 211 and each green sub-pixel 212 is the same, while the area of ​​the purple sub-pixel 213 is the same as the area of ​​the sky blue sub-pixel 214, and the area of ​​the purple sub-pixel 213 is smaller than the area of ​​the red sub-pixel 211. Specifically, the sum of the areas of the purple sub-pixel 213 and the sky blue sub-pixel 214 is equal to the area of ​​the red sub-pixel 211. That is to say, in this embodiment, the areas of the red sub-pixel 211 and the green sub-pixel 212 each occupy one-third of a pixel unit 21, while the areas of the purple sub-pixel 213 and the sky blue sub-pixel 214 together occupy one-third of a pixel unit 21.

[0047] In one embodiment, red sub-pixels 211 and green sub-pixels 212 are arranged at intervals along a first direction (X direction in Figure 3), and purple sub-pixels 213 and sky blue sub-pixels 214 are arranged at intervals along a second direction (Y direction in Figure 3). The intervals between purple sub-pixels 213 and green sub-pixels 212 in the first direction are the same as the intervals between sky blue sub-pixels 214 and green sub-pixels 212 in the first direction; the first and second directions are perpendicular. For example, the first direction is the length direction of the color filter substrate 2, and the second direction is the width direction of the color filter substrate 2. Essentially, in this embodiment, purple sub-pixels 213 and sky blue sub-pixels 214 jointly occupy the area originally occupied by the blue sub-pixels, and are arranged at intervals with red sub-pixels 211 and green sub-pixels 212 in the first direction.

[0048] In this embodiment, the sky-blue sub-pixel 214 and the purple sub-pixel 213 are arranged adjacently to facilitate the light mixing effect between them, thereby avoiding harmful blue light display. Meanwhile, the red sub-pixel 211, the green sub-pixel 212, and the sky-blue and purple sub-pixels 214 are arranged alternately to facilitate light mixing among multiple sub-pixels in a single pixel unit 21.

[0049] In this context, the positions of red sub-pixel 211 and green sub-pixel 212 can be interchanged, as can the positions of sky blue sub-pixel 214 and purple sub-pixel 213. Furthermore, the positions of sky blue sub-pixel 214 and purple sub-pixel 213 can be interchanged with the positions of red sub-pixel 211 and green sub-pixel 212.

[0050] Please continue referring to Figure 1. In some embodiments, the display panel further includes a black matrix layer 215. The black matrix layer 215 is disposed on the side of the color filter substrate 2 facing the array substrate 1. The black matrix layer 215 divides the color filter substrate 2 into several sub-regions, and each sub-region corresponds to a sub-pixel. In this embodiment, the spacing between adjacent sub-pixels is achieved through the black matrix layer 215, and each sub-region can be coated with a color resist material to form a red sub-pixel 211, a green sub-pixel 212, a sky blue sub-pixel 214, and a purple sub-pixel 213 of the color filter layer. The above configuration is easily understood and implemented by those skilled in the art, and therefore will not be described in detail here.

[0051] In some embodiments, both the first pixel driving structure and the second pixel driving structure are connected to a control line. The first pixel driving structure is connected to a first data line, and the second pixel driving structure is connected to a second data line. In this embodiment, independent pixel driving structures 11 are used for the sky blue sub-pixel 214 and the purple sub-pixel 213, which can realize the individual control of the two sub-pixels to adjust their respective light transmission brightness for light mixing.

[0052] Please refer to Figure 4. The first pixel driving structure includes a first thin-film transistor 41, and the corresponding second pixel driving structure includes a second thin-film transistor 42. Compared to the original setting of one blue sub-pixel in one pixel unit 21, an additional thin-film transistor is added. The structures of the first thin-film transistor 41 and the second thin-film transistor 42 in this embodiment are shown in Figure 4. The first thin-film transistor 41 includes a first gate 411, a first TFT channel layer 412, a first source 413, a first pixel electrode 414, a first insulating layer 415, and a common electrode 416. The first TFT communication layer is located on the first gate 411. The first source 413 and the first pixel electrode 414 are located on the same layer at intervals on the first TFT channel layer 412. The first insulating layer 415 is located on the first source 413 and partially covers the first pixel electrode 414. The common electrode 416 is located on the side of the color filter substrate 2 closer to the array substrate 1. Liquid crystal is disposed between the color filter substrate 2 and the array substrate 1. The second thin-film transistor 42, located on the array substrate 1, includes a second gate 421, a second TFT channel layer 422, a second source 423, a second pixel electrode 424, and a second insulating layer 425. The second TFT communication layer is located on the second gate 421. The second source 423 and the second pixel electrode 424 are located on the same layer at a distance from each other on the second TFT channel layer 422. The second insulating layer 425 is located on the second source 423 and partially covers the second pixel electrode 424. The gate of the thin-film transistor is connected to a corresponding control line, which controls the transistor's on / off state. The source of the thin-film transistor is connected to a corresponding data line, which writes display content through the transistor. The structure of the thin-film transistor in the array substrate 1 is easily understood and implemented by those skilled in the art, and therefore will not be described in detail here.

[0053] This application embodiment also provides a display panel, which includes an array substrate and a color filter substrate stacked together. The color filter substrate includes a color filter layer. The color filter layer is divided into a plurality of pixel units arranged in a periodic repeating pattern. Each pixel unit includes a red sub-pixel, a green sub-pixel, a purple sub-pixel, and a sky blue sub-pixel. The array substrate is provided with a first pixel driving structure corresponding to the sky blue sub-pixel and a second pixel driving structure corresponding to the purple sub-pixel. The first pixel driving structure is used to control the brightness of the sky blue sub-pixel transmitted through a first target wavelength light and to control the brightness of the purple sub-pixel transmitted through a second target wavelength light.

[0054] In this embodiment, by replacing the original blue sub-pixel with two sub-pixels—a purple sub-pixel and a sky-blue sub-pixel—for display, the harmful blue light band in the original blue sub-pixel can be avoided, thus preventing harmful blue light display without affecting the accuracy of the displayed color. Since the display panel has been described in detail above, it will not be repeated here.

The backlight module is provided with a light source component corresponding to each sub-pixel, and the light source component provides light to each corresponding sub-pixel. Each pixel driving circuit controls the corresponding light source component to be lit or turned off. When a pixel driving circuit drives the corresponding light source component to emit light, the light shines on the sub-pixel of the corresponding color and emits light of the corresponding color.

[0056] In this embodiment, the pixel driving structure corresponding to the sky-blue sub-pixel is the first pixel driving structure, and the pixel driving structure corresponding to the purple sub-pixel is the second pixel driving structure. The first pixel driving structure controls the brightness of the sky-blue sub-pixel transmitted through the first target wavelength light, and also controls the brightness of the purple sub-pixel transmitted through the second target wavelength light, so that the purple and sky-blue sub-pixels achieve light mixing, thus controlling the pixel chromaticity of the pseudo-blue sub-pixel formed by the color mixing. In this embodiment, by replacing the blue sub-pixel in the original pixel unit with two sub-pixels, a purple sub-pixel and a sky-blue sub-pixel, for display, the harmful blue light wavelength in the original blue sub-pixel can be avoided, thereby preventing harmful blue light display without affecting the accuracy of the displayed color.
