Description

Display module and display device

[0002] The present application relates to the field of display, and in particular to a display module and a display device. Background Art

[0003] With the development of liquid crystal display technology, especially the development of full-screen technology, under-screen camera technology has been widely used. For example, under-screen camera technology is used in vehicle-mounted display devices, and can monitor the driver's seat belt, fatigue, distraction, etc. through infrared sensors. Under-screen camera technology sets the camera on the backlight side of the display panel without destroying the integrity of the display panel, and divides the display area of ​​the display panel into a regular display area and a camera area. When the camera is turned off, the camera area also participates in the picture display, thereby achieving full-screen display. In existing display modules that use under-screen camera technology, since the backlight component of the display module needs to have a larger hole to ensure the imaging effect of the camera, there is no light source in the hole area, resulting in the display picture in the camera area of ​​the display panel being dark or even no display picture, and the display effect is affected.

[0004] Therefore, there is an urgent need for a display module and a display device to solve the above technical problems. SUMMARY OF THE INVENTION

[0033] In some embodiments, the present application provides a display module having a first display area and a second display area surrounding the first display area, the display module comprising:

[0037] The reflectivity of the filter portion to visible light is greater than or equal to 90%, and the transmittance of the filter portion to infrared light is greater than or equal to 80%.

[0038] In some embodiments, the light source section includes a plurality of first-type light source sub-sections and a plurality of second-type light source sub-sections, wherein the first-type light source sub-sections are arranged around the first light-transmitting sub-section, and the second-type light source sub-sections are located on a side of the first-type light source sub-section away from the light-transmitting section;

[0039] The minimum distance between the first type of light source sub-unit and the second type of light source sub-unit is smaller than the minimum distance between the second type of light source sub-units.

[0041] In some embodiments, the control unit of the first type of light source sub-section is different from the control unit of the second type of light source sub-section.

[0042] In some embodiments, the light-transmitting portion further includes a second light-transmitting sub-portion, and the second light-transmitting sub-portion is located on a side of the light source layer close to the display panel;

[0043] The orthographic projection of the first light-transmitting sub-section on the display panel is located within the orthographic projection of the second light-transmitting sub-section on the display panel.

[0044] In some embodiments, the orthographic projection of the light filtering portion on the display panel is located within the orthographic projection of the second light-transmitting sub-portion on the display panel;

[0052] In the display module and display device provided in the embodiments of the present application, the filter portion covers the first light-transmitting sub-portion through the setting of the filter portion, and the filter portion reflects visible light and transmits infrared light. When the display module is applied to the display device, the display panel does not affect the infrared light sensor's reception of infrared light when normally displaying the picture, and increases the light output of the light source portion in the light-transmitting portion, thereby improving the picture display uniformity of the first display area and the second display area of ​​the display module and improving the display effect.

[0053] The display module and display device of the present application will be described in detail below with reference to the accompanying drawings and specific implementations.

[0054] 1 to 6 , an embodiment of the present application provides a display module 100 having a first display area 102 and a second display area 103 surrounding the first display area 102 . The display module 100 includes:

[0055] Display panel 101;

[0056] A backlight assembly 104 is located on one side of the display panel 101 and includes a light-transmitting portion 105 located in the first display area 102;

[0057] The backlight assembly 104 includes a light source layer 106, and the light-transmitting portion 105 includes a first light-transmitting sub-portion 107. The first light-transmitting sub-portion 107 is located on a side of the light source layer 106 away from the display panel 101. The light source layer 106 includes a light source portion 108 and a filter portion 109. The orthographic projection of the first light-transmitting sub-portion 107 on the display panel 101 is located within the orthographic projection of the filter portion 109 on the display panel 101.

[0058] The reflectivity of the filter portion 109 to visible light is greater than or equal to 90%, and the transmittance of the filter portion 109 to infrared light is greater than or equal to 80%.

[0059] In the embodiment of the present application, a filter portion 109 is provided in the backlight assembly 104. The filter portion 109 covers the first light-transmitting sub-portion 107, and the filter portion 109 reflects visible light and transmits infrared light. When the display module 100 is applied to a display device, the display panel 101 does not affect the infrared light sensor's reception of infrared light when normally displaying an image, and increases the light output of the light source portion 108 in the light-transmitting portion 105, thereby improving the image display uniformity of the first display area 102 and the second display area 103 of the display module 100 and enhancing the display effect.

[0060] The technical solution of this application is now described in conjunction with specific embodiments.

[0061] In this embodiment, the reflectivity of the filter 109 for visible light is greater than or equal to 90%, and the transmittance of the filter 109 for infrared light is greater than or equal to 80%. Visible light is light with a wavelength between 400 nanometers and 760 nanometers; infrared light has a wavelength greater than 760 nanometers. The reflectivity of the filter 109 for visible light can be 91%, 92%, 93%, 95%, 96%, 97%, 99%, 100%, etc., and the transmittance of the filter 109 for infrared light can be 82%, 84%, 85%, 88%, 90%, 95%, 96%, 100%, etc. The filter 109's reflection of visible light facilitates the reflection of light from the light source 108 through the filter 109 into the light-transmitting portion 105, thereby increasing the amount of light emitted by the light source 108 at the light-transmitting portion 105, improving the uniformity of the image display between the first display area 102 and the second display area 103, and enhancing the display quality of the display module 100. The filter 109's ability to transmit infrared light prevents interference with the infrared light sensor located in the light-transmitting portion 105 when the display module 100 is used in a display device.

[0062] In some embodiments, the material of the filter portion 109 may include polyethylene terephthalate (PET) or polycarbonate (PC).

[0063] In some embodiments, the filter portion 109 can be formed of a commercial film material, such as a near infrared transmission system-reflector film (NSR). Referring to FIG. 7 , the filter portion 109 formed of a commercial near infrared transmission system-reflector film has an infrared transmittance greater than or equal to 84% and a visible light transmittance less than or equal to 1%, meaning its visible light reflectance is greater than or equal to 99%.

[0064] Please refer to Figures 1 to 6. In some embodiments, the light source portion 108 includes multiple first-type light source sub-portions 110 and multiple second-type light source sub-portions 111. The first-type light source sub-portions 110 are arranged around the first light-transmitting sub-portion 107, and the second-type light source sub-portions 111 are located on the side of the first-type light source sub-portion 110 away from the light-transmitting portion 105.

[0065] Referring to Figure 6, in some embodiments, within a first plane, which is parallel to the light-emitting surface of the display panel 101, multiple first-type light source sub-segments 110 are distributed in a ring-like pattern along a direction surrounding the first light-transmitting sub-segment 107. The first plane is a plane parallel to the light-emitting surface of the display panel 101. The multiple first-type light source sub-segments 110 are distributed in a ring-like pattern along a direction surrounding the first light-transmitting sub-segment 107. That is, the light source section 108 includes at least one first-type light source group 112, and each circle of the multiple first-type light source sub-segments 110 disposed around the first light-transmitting sub-segment 107 belongs to the same first-type light source group 112. Within a second plane, which is perpendicular to the first plane, the number of first-type light source sub-segments 110 spaced between the first light-transmitting sub-segment 107 and the first light-transmitting sub-segment 100 within the same first-type light source group 112 is the same. For example, the number of first-type light source sub-sections 110 spaced between the first-type light source sub-section 110 and the first light-transmitting sub-section 107 in the first-type light source group 112 closest to the first light-transmitting sub-section 107 (that is, the first-type light source group 112 formed by the first-type light source sub-sections 110 in the first circle surrounding the first light-transmitting sub-section 107) is 0; the number of first-type light source sub-sections 110 spaced between the first-type light source sub-section 110 and the first light-transmitting sub-section 107 in the first-type light source group 112 second closest to the first light-transmitting sub-section 107 (that is, the first-type light source group 112 formed by the second circle of first-type light source sub-sections 110 surrounding the first light-transmitting sub-section 107) is 1.

[0066] In some embodiments, within a first plane, a plurality of the first-type light source sub-units 110 are distributed in an array along a first direction X and a second direction Y, where the first direction X is perpendicular to the second direction Y. It is understood that "perpendicular" in this application refers to perpendicularity within a certain angular error range, for example, 85° to 95° can be interpreted as perpendicularity.

[0067] In some embodiments, within a first plane, multiple second-type light source sub-sections 111 are distributed in a ring-like pattern around the first light-transmitting sub-section 107. This means that the light source section 108 includes multiple second-type light source groups 113, and each circle of multiple second-type light source sub-sections 111 surrounding the first light-transmitting sub-section 107 belongs to the same second-type light source group 113. Within a second plane, the number of first-type light source sub-sections 110 and the number of second-type light source sub-sections 111 spaced between the second-type light source sub-sections 111 and the first light-transmitting sub-section 107 within the same second-type light source group 113 are the same. For example, when the number of the first-type light source groups 112 is 1, the number of the first-type light source sub-sections 110 spaced between the second-type light source sub-sections 111 and the first light-transmitting sub-section 107 in the second-type light source group 113 closest to the first light-transmitting sub-section 107 (that is, the second-type light source group 113 formed by the first circle of the second-type light source sub-sections 111 surrounding the first light-transmitting sub-section 107) is 1; the number of the first-type light source sub-sections 110 spaced between the second-type light source sub-sections 111 and the first light-transmitting sub-section 107 in the second-type light source group 113 second closest to the first light-transmitting sub-section 107 (that is, the second-type light source group 113 formed by the second circle of the second-type light source sub-sections 111 surrounding the first light-transmitting sub-section 107) is 1, and the number of the second-type light source sub-sections 111 is 1.

[0068] Referring to FIG. 6 , in some embodiments, within a first plane, a plurality of the second-type light source sub-sections 111 are distributed in an array along a first direction X and a second direction Y, where the first direction X is perpendicular to the second direction Y.

[0069] In some embodiments, along the direction from the center to the periphery of the first display area 102, the minimum spacing between the first-type light source sub-sections 110 is smaller than the minimum spacing between the first-type light source sub-sections 110 and the second-type light source sub-sections 111. That is, along the direction from the first-type light source sub-sections 110 to the second-type light source sub-sections 111, the minimum spacing between the first-type light source sub-sections 110 and the second-type light source sub-sections 111 is smaller than the minimum spacing between the second-type light source sub-sections 111. For example, in the first direction X, the minimum spacing between the first-type light source sub-sections 110 and the second-type light source sub-section 111 closest to the first-type light source sub-section 110 is the minimum spacing between the first-type light source sub-sections 110 and the second-type light source sub-section 111; and in the first direction X, the minimum spacing between the second-type light source sub-sections 111 is the minimum spacing between the second-type light source sub-sections 111. Alternatively, in the second direction Y, the minimum distance between a plurality of first-type light source sub-units 110 within the same group and the second-type light source sub-unit 111 closest to the first-type light source sub-unit 110 is the minimum spacing between the first-type light source sub-unit 110 and the second-type light source sub-unit 111; and the minimum spacing between a plurality of adjacent second-type light source sub-units 111 is the minimum spacing between the second-type light source sub-units 111 in the second direction Y. The above spacing arrangement facilitates increasing the density of the light source units 108 near the light-transmitting portion 105 and the amount of light emitted by the light source units 108 in the light-transmitting portion 105, thereby reducing the brightness difference between the first display area 102 and the second display area 103 of the display module 100, improving the uniformity of image display, and enhancing the display effect of the display module 100.

[0070] In some embodiments, along the direction from the first type of light source sub-unit 110 to the second type of light source sub-unit 111, the ratio of the minimum spacing between the first type of light source sub-unit 110 and the second type of light source sub-unit 111 to the minimum spacing between the second type of light source sub-unit 111 is greater than or equal to 1:1.5 and less than or equal to 1:2. For example, it can be 1:1.6, 1:1.7, 1:1.8, 1:1.9, etc., which is conducive to the reasonable arrangement of the light source unit 108, reducing the brightness difference between the first display area 102 and the second display area 103 of the display module 100, improving the uniformity of the picture display, and enhancing the display effect of the display module 100.

[0071] In some embodiments, along the direction from the first type of light source sub-section 110 to the second type of light source sub-section 111, the minimum spacing between the first type of light source sub-section 110 and the second type of light source sub-section 111 is greater than or equal to 1 mm and less than or equal to 3 mm, for example, it can be 1.2 mm, 1.5 mm, 1.8 mm, 2 mm, 2.2 mm, 2.4 mm, 2.5 mm, 2.8 mm, etc.

[0072] In some embodiments, along the direction from the first type of light source sub-section 110 to the second type of light source sub-section 111, the minimum spacing between the second type of light source sub-sections 111 is greater than or equal to 2 mm and less than or equal to 4 mm, for example, it can be 2.2 mm, 2.4 mm, 2.5 mm, 2.8 mm, 3 mm, 3.2 mm, 3.5 mm, 3.6 mm, 3.8 mm, etc.

[0073] In some embodiments, along the direction from the first-type light source sub-section 110 to the second-type light source sub-section 111, the minimum spacing between the first-type light source sub-sections 110 is smaller than the minimum spacing between the first-type light source sub-sections 110 and the second-type light source sub-sections 111. Specifically, along the direction from the first-type light source sub-section 110 to the second-type light source sub-section 111, the minimum spacing between the first-type light source sub-sections 110 is the minimum spacing between the first-type light source sub-sections 110; and along the direction from the first-type light source sub-section 110 to the second-type light source sub-section 111, the minimum spacing between the second-type light source sub-sections 111 is the minimum spacing between the second-type light source sub-sections 111. The above-mentioned spacing setting is beneficial to increasing the density of the light source unit 108 close to the light-transmitting portion 105, and increasing the amount of light emitted by the light source unit 108 in the light-transmitting portion 105, thereby reducing the brightness difference between the first display area 102 and the second display area 103 of the display module 100, improving the uniformity of the picture display, and enhancing the display effect of the display module 100.

[0074] In some embodiments, along the direction from the first type of light source sub-section 110 to the second type of light source sub-section 111, the minimum spacing between the first type of light source sub-sections 110 is greater than or equal to 1 mm and less than or equal to 2 mm, for example, it can be 1.24 mm, 1.25 mm, 1.26 mm, 1.3 mm, 1.32 mm, 1.35 mm, 1.36 mm, 1.4 mm, 1.42 mm, 1.45 mm, 1.46 mm, 1.48 mm, 1.5 mm, 1.52 mm, 1.55 mm, 1.56 mm, 1.6 mm, 1.62 mm, 1.64 mm, 1.65 mm, 1.66 mm, 1.68 mm, 1.7 mm, 1.72 mm, 1.74 mm, 1.76 mm, 1.78 mm, 1.8 mm, 1.82 mm, 1.85 mm, 1.88 mm, 1.9 mm, 1.95 mm, 1.98 mm, etc.

[0075] In some embodiments, the control unit of the first-type light source sub-unit 110 is different from the control unit of the second-type light source sub-unit 111. The control unit of the first-type light source sub-unit 110 and the control unit of the second-type light source sub-unit 111 are respectively used to transmit control signals to the first-type light source sub-unit 110 and the second-type light source sub-unit 111, respectively, for turning on, off, and controlling the brightness of the first-type light source sub-unit 110 and the second-type light source sub-unit 111. Because the control unit of the first-type light source sub-unit 110 is different from the control unit of the second-type light source sub-unit 111, the first-type light source sub-unit 110 and the second-type light source sub-unit 111 are controlled separately, achieving a difference in the luminance of the first-type light source sub-unit 110 and the luminance of the second-type light source sub-unit 111, thereby reducing the brightness difference between the first display area 102 and the second display area 103 of the display module 100, improving the uniformity of the picture display, and enhancing the display effect of the display module 100.

[0076] In some embodiments, the light source unit 108 may be an LED (Light Emitting Diode) type light emitting device, such as a Mini LED (mini light emitting diode).

[0077] Referring to Figures 1 to 5, in some embodiments, the backlight assembly 104 further includes a driving layer 114, which is located on a side of the light source layer 106 away from the display panel 101. The control unit of the first-type light source sub-unit 110 and the control unit of the second-type light source sub-unit 111 are at least partially located in the driving layer 114. That is, the first-type light source sub-unit 110 and the second-type light source sub-unit 111 are respectively fixedly connected to the driving layer 114. When the light source unit 108 is an LED-type light-emitting device, the driving layer 114 can be a light board, and the light source unit 108 is fixed to the side of the driving layer 114 close to the display panel 101 by welding or other processes.

[0078] In some embodiments, the light emitting surface of the light source unit 108 is located on a side of the driving layer 114 close to the display panel 101.

[0095] In some embodiments, the orthographic projection of the first type of light source group 112, which is the second closest to the first light-transmitting sub-section 107 in the first direction X and / or the second direction Y, on the display panel 101 is at least partially located within the orthographic projection of the second light-transmitting sub-section 115 on the display panel 101, which is beneficial to further increase the amount of light provided by the light source section 108 to the first display area 102 of the display panel 101, thereby reducing the brightness difference between the first display area 102 and the second display area 103 of the display module 100, improving the uniformity of the picture display, and enhancing the display effect of the display module 100.

[0097] In some embodiments, the lens members 116 are provided in a one-to-one correspondence with the light source units 108 whose orthographic projections on the display panel 101 are located within the orthographic projections of the second light-transmitting sub-units 115 on the display panel 101. Referring to Figures 8 and 9 , by providing the lens members 116 in a one-to-one correspondence with the first-type light source sub-units 110 within the first-type light source group 112 that is closest to the first light-transmitting sub-unit 107 in the first direction X and / or the second direction Y, the light emission angle of the first light-transmitting sub-unit 107 is significantly changed, causing more light to be deflected into the area covered by the orthographic projections of the first light-transmitting sub-units 107 on the display panel 101.
