Description

Technical Field

[0001] The present application relates to the field of display technology, and in particular to a display screen. Background Art

[0002] With the development of smart mobility, there is a demand for more transparent displays on the windows of buses or cars. However, in the related art, the displays on the windows are prone to display abnormalities. Summary of the invention

[0003] Based on this, it is necessary to provide a display screen to address the problem that displays on car windows are prone to display abnormalities in related technologies.

[0004] The present application provides a display screen, comprising a substrate, a display module and at least one functional layer, wherein the display module is arranged on the substrate, and the at least one functional layer is arranged on a side of the display module close to and / or away from the substrate, wherein a plurality of infrared reflective particles are arranged in at least one of the functional layers.

[0005] In the technical solution of the present application, when the display screen of the present application is used, normal display can be achieved by utilizing the display module, and infrared rays can be reflected by utilizing multiple infrared reflecting particles in the functional layer, thereby effectively blocking the heat of sunlight from propagating to the interior of the display screen, thereby reducing the temperature of the display screen and the probability of display abnormalities on the display screen.

[0006] In one embodiment, the particle size of the infrared reflective particles is less than or equal to 2000nm. The particle size of the infrared reflective particles is relatively small. On the one hand, the sufficiently small infrared reflective particles occupy a very small proportion of the space in the functional layer, which will not affect the transmittance of visible light, making it easy for the display screen to be used in transparent display scenes; it will not affect the function of the functional layer itself; on the other hand, multiple infrared reflective particles can be used to reflect infrared rays, thereby effectively blocking the heat of sunlight from propagating to the inner layer, thereby reducing the temperature of the display screen, and further reducing the probability of display abnormalities on the display screen.

[0007] In one embodiment, the infrared reflective particles include metal particles and / or metal oxide particles. The metal particles and / or metal oxide particles can be used to improve the infrared shielding rate, and then the plurality of infrared reflective particles can be better used to reflect infrared rays, and then the heat of sunlight can be well blocked from propagating to the inner layer, and then the temperature of the display screen can be reduced, and the probability of display abnormality of the display screen can also be reduced.

[0008] In one embodiment, the infrared reflective particles include metal particles, and the particle size of the metal particles is a, wherein 5nm≤a≤500nm. After the particle size of the metal particles is reduced to a certain size, due to the resonance effect between the surface of the metal particles and the functional layer, the metal particles will absorb / reflect light of different wavelengths depending on their particle size. Therefore, it is necessary to set the particle size of the metal particles within a suitable range, such as making a satisfy the condition of 5nm≤a≤500nm, which is beneficial for multiple infrared reflective particles to better reflect infrared rays, so as to better reduce the probability of display anomalies on the display screen. In addition, the smaller particle size of the metal particles is also beneficial for improving the light transmittance of the display screen, so that the display screen is applied to transparent display scenarios.

[0009] In one embodiment, the infrared reflective particles include metal oxide particles, and the particle size of the metal oxide particles is b, where 50nm≤b≤2000nm. Metal oxide particles absorb / reflect light of different wavelengths depending on their particle size. Therefore, it is necessary to set the particle size of the metal oxide particles within a suitable range, such as making b satisfy the condition of 50nm≤b≤2000nm, so as to better reflect infrared rays by multiple infrared reflective particles, so as to better reduce the probability of display abnormalities on the display screen. In addition, the smaller particle size of the metal particles is also conducive to improving the light transmittance of the display screen, so that the display screen is applied to transparent display scenarios.

[0010] In one embodiment, the display screen is used on a car window; the display screen further comprises an adhesive layer, and the adhesive layer is arranged on a side of the substrate away from the display module, or the adhesive layer is arranged on a side of the display module away from the substrate. It is convenient to fix the display screen on the car window, and the position of the adhesive layer can also be selected according to different application scenarios (such as the scene of displaying inside the car or the scene of displaying outside the car).

[0011] In one embodiment, the at least one functional layer includes an antistatic functional layer, and the antistatic functional layer is disposed on a side of the display module close to the substrate; a plurality of infrared reflective particles are disposed in the antistatic functional layer. Thus, on the one hand, the plurality of infrared reflective particles can be used to reflect infrared rays, thereby reducing the probability of display abnormalities on the display screen. On the other hand, due to the provision of the antistatic functional layer, the occurrence of static electricity damage to the circuit of the display screen caused by static electricity accumulation in the display screen can be reduced.

[0012] In one embodiment, the display screen is used on a vehicle window; the substrate, the antistatic functional layer and the display module are stacked and arranged along the direction from the outer wall of the vehicle window to the inner wall of the vehicle window; the display screen also includes an adhesive layer, and the adhesive layer is connected between the inner wall of the vehicle window and the substrate. Since the substrate, the antistatic functional layer and the display module are stacked and arranged along the direction from the outer wall of the vehicle window to the inner wall of the vehicle window, the display module is arranged inward, so that the display screen can be bonded and fixed to the vehicle window, and the information displayed by the display module (such as driving information, including travel speed and driving path, etc.) can also be viewed by the user in the vehicle.

[0013] In one embodiment, the at least one functional layer further includes an encapsulation functional layer, which is disposed on a side of the display module away from the antistatic functional layer; the encapsulation functional layer is provided with the infrared reflective particles or is not provided with the infrared reflective particles. The encapsulation functional layer can be used to encapsulate and protect the display module, thereby improving the display effect and reliability of the display screen.

[0014] In one embodiment, the at least one functional layer includes an encapsulation functional layer, which is disposed on a side of the display module away from the substrate; a plurality of infrared reflective particles are disposed in the encapsulation functional layer. Thus, on the one hand, a plurality of infrared reflective particles can be used to reflect infrared rays, thereby reducing the probability of display abnormalities on the display screen. On the other hand, due to the provision of the encapsulation functional layer, the display module can be encapsulated and protected by the encapsulation functional layer, thereby improving the display effect and reliability of the display screen.

[0015] In one embodiment, the display screen is used on a vehicle window; the substrate, the display module and the encapsulation function layer are stacked and arranged along the direction from the inner wall of the vehicle window to the outer wall of the vehicle window; the display screen also includes an adhesive layer, and the adhesive layer is connected between the inner wall of the vehicle window and the encapsulation function layer. Since the substrate, the display module and the encapsulation function layer are stacked and arranged along the direction from the inner wall of the vehicle window to the outer wall of the vehicle window, the display module is arranged outward, so that the display screen can be bonded and fixed to the vehicle window, and the information displayed by the display module (such as advertising information) can also be viewed by people outside the vehicle.

[0016] In one embodiment, the at least one functional layer further comprises an antistatic functional layer, and the antistatic functional layer is disposed between the substrate and the display module. Due to the provision of the antistatic functional layer, the occurrence of static electricity damage to the circuit of the display screen caused by static electricity accumulation in the display screen can be reduced.

[0017] In one embodiment, the display screen is a transparent display screen, which can be mounted on a car window to improve the experience of the display screen. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] In the related art, the display is often exposed to direct sunlight in vehicle applications, causing the temperature of the display module of the display to rise. When the display is in a high temperature environment for a long time, the display module or electronic components of the display are easily degraded, and even the display module is damaged, which leads to abnormal display of the display.

[0031] In order to solve the problem that the display on the car window is prone to display abnormalities, the present application designs a display screen that can reduce infrared thermal radiation, thereby lowering the temperature of the display screen, and further reducing the probability of display abnormalities on the display screen.

[0032] Figure 1 and Figure 2 A schematic diagram of the structure of the display screen 10 in one embodiment of the present application in different application scenarios is shown.

[0033] See also Figure 1 and Figure 2 An embodiment of the present application provides a display screen 10, including a substrate 100, a display module 200 and a functional layer 300, wherein the display module 200 is disposed on the substrate 100, and at least one functional layer 300 is disposed on a side of the display module 200 close to and / or away from the substrate 100, wherein at least one functional layer 300 is provided with a plurality of infrared reflective particles 400.

[0034] “At least one functional layer 300 is disposed on a side of the display module 200 close to and / or away from the substrate 100” may mean that the functional layer 300 is disposed on a side of the display module 200 close to the substrate 100; or that the functional layer 300 is disposed on a side of the display module 200 away from the substrate 100; or that one functional layer 300 is disposed on a side of the display module 200 close to the substrate 100, and the other functional layer 300 is disposed on a side of the display module 200 away from the substrate 100.

[0035] The display module 200 may be an LCD display module, an LED display module, an OLED display module, a QLED display module or a ULED display module, and is not specifically limited herein.

[0036] The infrared reflective particles 400 are particles that have infrared reflective properties and can reflect infrared rays.

[0037] Optionally, a plurality of infrared reflective particles 400 are uniformly distributed in the functional layer 300 .

[0038] Therefore, when the display screen 10 of the present application is used, normal display can be achieved by utilizing the display module 200, and infrared rays can be reflected by utilizing the plurality of infrared reflective particles 400 in the functional layer 300, thereby effectively blocking the heat of sunlight from propagating to the interior of the display screen 10, thereby lowering the temperature of the display screen 10, and also reducing the probability of display abnormalities occurring in the display screen 10.

[0039] In some embodiments, the particle size of the infrared reflective particles 400 is less than or equal to 2000 nm.

[0040] The particle size of the infrared reflective particles 400 is relatively small. On the one hand, the sufficiently small infrared reflective particles 400 occupy a very small proportion of the space in the functional layer 300, which will not affect the transmittance of visible light (such as light with a wavelength of 400nm-700nm), making it easy for the display screen 10 to be used in transparent display scenarios; it will not affect the function of the functional layer 300 itself; on the other hand, multiple infrared reflective particles 400 can be used to reflect infrared rays, thereby effectively blocking the heat of sunlight from propagating to the inner layer, thereby reducing the temperature of the display screen 10, and further reducing the probability of display abnormalities of the display screen 10.

[0041] In some embodiments, infrared reflective particles 400 include metal particles and / or metal oxide particles.

[0042] The infrared reflective particles 400 may include metal particles. Alternatively, the infrared reflective particles 400 may include metal oxide particles. Alternatively, the infrared reflective particles 400 may include metal particles and metal oxide particles.

[0043] Metal particles and / or metal oxide particles can be used to increase the infrared shielding rate, and then multiple infrared reflective particles 400 can be better utilized to reflect infrared rays, thereby effectively blocking the heat of sunlight from propagating to the inner layer, thereby reducing the temperature of the display screen 10 and the probability of display abnormalities on the display screen 10.

[0044] In some embodiments, the infrared reflective particles 400 include metal particles, and the particle size of the metal particles is a, wherein 5nm≤a≤500nm.

[0045] Optionally, the material of the metal particles includes at least one of gold, silver, aluminum, zinc, iron, nickel, titanium and tin.

[0046] After the particle size of the metal particles is reduced to a certain size, due to the resonance effect between the surface of the metal particles and the functional layer 300, the metal particles will absorb / reflect light of different wavelengths depending on their particle size. Therefore, the particle size of the metal particles needs to be set within a suitable range, such as making a satisfy the condition of 5nm≤a≤500nm, which is conducive to better reflection of infrared rays by the plurality of infrared reflective particles 400, so as to better reduce the probability of display abnormalities on the display screen 10. In addition, the smaller particle size of the metal particles is also conducive to improving the light transmittance of the display screen 10, so that the display screen 10 is applied in transparent display scenarios.

[0047] In some embodiments, the infrared reflective particles 400 include metal oxide particles, and the particle size of the metal oxide particles is b, wherein 50 nm≤b≤2000 nm.

[0048] Optionally, the material of the metal oxide particles includes at least one of iron oxide, titanium oxide, aluminum oxide, zinc oxide, chromium oxide, zirconium oxide and tin oxide.

[0049] Metal oxide particles absorb / reflect light of different wavelengths depending on their particle size. Therefore, the particle size of the metal oxide particles needs to be set within an appropriate range, such as b satisfies the condition of 50nm≤b≤2000nm, which is conducive to better reflection of infrared rays by the plurality of infrared reflective particles 400, so as to better reduce the probability of display abnormalities on the display screen 10. In addition, the smaller particle size of the metal particles is also conducive to improving the light transmittance of the display screen 10, so that the display screen 10 is applied in transparent display scenarios.

[0050] In some embodiments, the display screen 10 is used on a vehicle window 20 , and the display screen 10 further includes an adhesive layer 500 , which is disposed on a side of the substrate 100 away from the display module 200 , or on a side of the display module 200 away from the substrate 100 .

[0051] It is convenient to fix the display screen 10 on the vehicle window 20 , and the position of the adhesive layer 500 can also be selected according to different application scenarios (such as the scene of displaying inside the vehicle or the scene of displaying outside the vehicle).

[0052] For example, Figure 1 As shown, at least one functional layer 300 includes an antistatic functional layer 310 and an encapsulation functional layer 320. When the display screen 10 is used for in-vehicle display, the substrate 100, the antistatic functional layer 310, the display module 200 and the encapsulation functional layer 320 are stacked in sequence along the direction from the outer wall 21 of the vehicle window 20 to the inner wall 22 of the vehicle window 20, and the adhesive layer 500 is arranged between the inner wall 22 of the vehicle window 20 and the substrate 100.

[0053] For example, Figure 2 As shown, at least one functional layer 300 includes an antistatic functional layer 310 and an encapsulation functional layer 320. When the display screen 10 is used for an outdoor display scenario, the substrate 100, the antistatic functional layer 310, the display module 200 and the encapsulation functional layer 320 are stacked in sequence along the direction from the inner wall 22 of the window 20 to the outer wall 21 of the window 20, and the adhesive layer 500 is arranged between the inner wall 22 of the window 20 and the encapsulation functional layer 320.

[0054] In some embodiments, Figure 1 As shown, at least one functional layer 300 includes an antistatic functional layer 310, and the antistatic functional layer 310 is disposed on a side of the display module 200 close to the substrate 100. A plurality of infrared reflective particles 400 are disposed in the antistatic functional layer 310.

[0055] Thus, on the one hand, the antistatic functional layer 310 is closer to the sunlight than the display module 200, and the plurality of infrared reflective particles 400 in the antistatic functional layer 310 can be used to reflect infrared rays, which can effectively block the heat of sunlight from propagating into the interior of the display module 200, thereby reducing the probability of display abnormalities in the display screen 10. On the other hand, due to the provision of the antistatic functional layer 310, the occurrence of the circuit of the display screen 10 being damaged by static electricity due to static electricity accumulation in the display screen 10 can be reduced.

[0056] In some embodiments, please refer to Figure 1 The display screen 10 is used on the vehicle window 20, along the outer wall 21 of the vehicle window 20 pointing to the direction of the inner wall 22 of the vehicle window 20, the substrate 100, the antistatic functional layer 310 and the display module 200 are stacked, and the display screen 10 also includes an adhesive layer 500, which is connected between the inner wall 22 of the vehicle window 20 and the substrate 100.

[0057] Since the substrate 100, the antistatic functional layer 310 and the display module 200 are stacked and arranged along the direction from the outer wall 21 of the vehicle window 20 to the inner wall 22 of the vehicle window 20, the display module 200 is arranged inwardly, so that the display screen 10 can be bonded and fixed to the vehicle window 20 while allowing the user in the vehicle to view the information displayed on the display module 200 (such as driving information, including travel speed and driving path, etc.).

[0058] In this example, please continue to refer to Figure 1 At least one functional layer 300 further includes an encapsulation functional layer 320, which is disposed on a side of the display module 200 away from the antistatic functional layer 310. The encapsulation functional layer 320 is provided with infrared reflective particles 400 or is not provided with infrared reflective particles 400.

[0059] Infrared reflective particles 400 may be provided in the encapsulation functional layer 320 ; or infrared reflective particles 400 may not be provided in the encapsulation functional layer 320 , which is not specifically limited herein.

[0060] The encapsulation function layer 320 can be used to encapsulate and protect the display module 200 , thereby improving the display effect and reliability of the display screen 10 .

[0061] In some other embodiments, see Figure 2 At least one functional layer 300 includes an encapsulation functional layer 320 . The encapsulation functional layer 320 is disposed on a side of the display module 200 away from the substrate 100 . A plurality of infrared reflective particles 400 are disposed in the encapsulation functional layer 320 .

[0062] Thus, on the one hand, the encapsulation function layer 320 is closer to the sunlight than the display module 200, and the plurality of infrared reflective particles 400 in the encapsulation function layer 320 can be used to reflect infrared rays, which can effectively block the heat of sunlight from propagating into the interior of the display module 200, thereby reducing the probability of display abnormalities on the display screen 10. On the other hand, due to the provision of the encapsulation function layer 320, the encapsulation function layer 320 can be used to encapsulate and protect the display module 200, thereby improving the display effect and reliability of the display screen 10.

[0063] In this example, please continue to refer to Figure 2 The display screen 10 is used on the vehicle window 20 , along the inner wall 22 of the vehicle window 20 pointing to the direction of the outer wall 21 of the vehicle window 20 , the substrate 100 , the display module 200 and the encapsulation functional layer 320 are stacked, and the display screen 10 also includes an adhesive layer 500 , which is connected between the inner wall 22 of the vehicle window 20 and the encapsulation functional layer 320 .

[0064] Since the substrate 100, the display module 200 and the encapsulation functional layer 320 are stacked and arranged along the direction from the inner wall 22 of the vehicle window 20 to the outer wall 21 of the vehicle window 20, the display module 200 is arranged outward. In this way, the display screen 10 can be bonded and fixed to the vehicle window 20 while people outside the vehicle can view the information displayed on the display module 200 (such as advertising information).

[0065] In this example, please continue to refer to Figure 2 , at least one functional layer 300 further includes an antistatic functional layer 310 , and the antistatic functional layer 310 is disposed between the substrate 100 and the display module 200 .

[0066] Due to the provision of the antistatic functional layer 310 , the occurrence of static electricity accumulation in the display screen 10 causing the circuit of the display screen 10 to be damaged by static electricity can be reduced.

[0067] In some embodiments, the display screen 10 is a transparent display screen.

[0068] The transparent display screen can be mounted on the vehicle window 20 to improve the user experience of the display screen 10 .

[0069] like Figure 3 and Figure 4 As shown, in order to verify the heat insulation effect of the display screen 10 of the present application, the display screen 10 of the present application and the display screen 30 of the comparative example are respectively bonded to a transparent glass plate 40 (used to simulate the car window 20) for comparative experiments, and the transparent glass plate 40 is irradiated by an infrared light source 50. The infrared reflective particles 400 of the present application are not set in the antistatic layer and the packaging layer of the display screen 30 of the comparative example.

[0070] Figure 5A trend diagram of the temperature of the display screen 10 of the present application and the display screen 30 of the comparative example as a function of the irradiation time of the infrared light source 50 is given (the temperature of the display screen 10 of the present application can be obtained by a first temperature probe disposed on the display module 200 of the display screen 10, and the temperature of the display screen 30 can also be obtained by a second temperature probe disposed on the display module of the display screen 30). Figure 5 In the figure, the horizontal axis is the irradiation time of the infrared light source 50, and the vertical axis is the temperature. The curve of the change of the temperature of the display screen 10 of the present application with the irradiation time of the infrared light source 50 is marked as L1, and the curve of the change of the temperature of the display screen 30 of the comparative example with the irradiation time of the infrared light source 50 is marked as L2. Figure 5 It can be seen that after 10 minutes of irradiation by the infrared light source 50, the temperature of the comparative display 30 (without the infrared reflective particles 400) reaches 60°C, while the temperature of the display screen 10 of the present application reaches 50°C. It can be seen that the display screen 10 of the present application can significantly reduce the thermal radiation of infrared rays, thereby lowering the temperature of the display screen 10, and thereby reducing the probability of display abnormalities of the display screen 10.

[0071] In summary, the display screen 10 of the present application can be used on the vehicle window 20, such as in the scene of in-vehicle display or in the scene of outside vehicle display, and the multiple infrared reflective particles 400 in the functional layer 300 can be used to reflect infrared rays, thereby effectively blocking the heat of sunlight from propagating to the inner layer, thereby reducing the temperature of the display screen 10 and the probability of display abnormality of the display screen 10. Compared with the heat dissipation method of heat sink and heat dissipation paste, the present application adopts sufficiently small infrared reflective particles 400, which can reduce the probability of display abnormality of the display screen 10 without affecting the light transmittance of the display screen 10, so as to facilitate the application of the display screen 10 in transparent display scenes.

[0072] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0073] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
