Description

Technical Field

[0001] The present invention relates to the technical field of displays, and in particular to a liquid-cooled display and an interface interaction device. Background Art

[0002] Displays are products used to display images and text information on interface interactive devices. With the development of technology, there is a high demand for display effects, including brightness, resolution, color tone, etc. Among them, the brightness of the display is determined by the light intensity provided by the backlight source. High-brightness display effect means high-power light output of the backlight source, which will generate a lot of heat and have an adverse effect on the display panel in the display.

[0003] In the prior art, air cooling is usually used to dissipate heat from the display panel. This method requires a heat dissipation channel and a fan to be set in the display. The fan accelerates the air flow at the display panel to achieve heat dissipation. This heat dissipation method has poor heat dissipation effect and low heat dissipation efficiency. The structure of the heat dissipation channel and the fan will increase the volume of the display. At the same time, the fan will generate noise when running. Due to the air flow, dust will be drawn into the heat dissipation channel to cause dust accumulation. Although the dust filter can filter dust, it needs to be cleaned and replaced regularly, which increases the maintenance cost. Summary of the invention

In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.

[0042] like Figures 1 to 6 As shown, the first embodiment of the present invention provides a liquid-cooled display, including a display panel 10, a backlight source 20 and a light-transmitting liquid cold plate 30. The backlight source 20 is arranged on the light-incident side of the display panel 10; the light-transmitting liquid cold plate 30 is attached to the display panel 10, and a cavity suitable for accommodating a light-transmitting cooling liquid 40 is formed in the light-transmitting liquid cold plate 30.

[0043] The liquid-cooled display in the embodiment of the present invention may be a liquid crystal display, wherein the display panel 10 itself does not emit light, and the pixels in the display panel 10 have the light modulation function of a light valve, and are usually combined with a backlight source 20 to display an image, and the backlight source 20 may include an LED array. The liquid-cooled display in the embodiment of the present invention may be applied to devices such as projectors, computers, and televisions.

[0044] The light-transmitting liquid cold plate 30 can transmit light and will not affect the light and the display effect of the display panel 10. For example, the light-transmitting liquid cold plate 30 can be made of optical glass, and the light-transmitting cooling liquid 40 in its cavity is also made of liquid with extremely low optical loss and good thermal conductivity. The light-transmitting liquid cold plate 30 is attached to the display panel 10, which means that there is no gap-type contact connection between the light-transmitting liquid cold plate 30 and the display panel 10.

[0045] According to the liquid-cooled display provided by the embodiment of the first aspect of the present invention, the display is cooled and cooled by liquid cooling to achieve heat dissipation. Specifically, the display includes a display panel 10, a backlight source 20 and a light-transmitting liquid cold plate 30, wherein the backlight source 20 can emit light so that the display panel 10 can display an image, and a light-transmitting cooling liquid 40 is stored in the light-transmitting liquid cold plate 30, and the light-transmitting liquid cold plate 30 is integrally attached to the display panel 10, which is conducive to improving the heat conduction efficiency. Therefore, the heat in the display panel 10 can be directly and quickly transferred to the light-transmitting cooling liquid 40 in the light-transmitting liquid cold plate 30, and the light-transmitting cooling liquid 40 absorbs the heat of the display panel 10, so as to achieve rapid cooling of the display panel 10, and the heat dissipation effect is good and the heat dissipation efficiency is high. Both the light-transmitting liquid cold plate 30 and the light-transmitting cooling liquid 40 have a light-transmitting function, which will not affect the image display effect of the display panel 10, and the light-transmitting liquid cold plate 30 is closely attached to the display panel 10, so that the overall thickness of the display is reduced, the structure of the display is optimized, the lightweight design of the display is achieved, and the design cost and maintenance cost are reduced.

[0046] In addition, the traditional air-cooling heat dissipation is greatly affected by the ambient temperature. The liquid-cooled display provided by the embodiment of the present invention is less affected by the ambient temperature because it uses liquid cooling to dissipate heat. Therefore, it is also suitable for the situation where the heat accumulation of the display panel 10 is caused by the influence of the ambient temperature. It has more application scenarios and stronger environmental adaptability. Liquid cooling heat dissipation does not generate noise, and can also prevent dust accumulation on the display panel 10, thereby increasing the service life of the display panel 10.

[0047] like Figures 3 to 6 As shown, in an embodiment of the present invention, the light-transmitting liquid cooling plate 30 is attached to the light-incident side of the display panel 10 , and / or the light-transmitting liquid cooling plate 30 is attached to the light-exiting side of the display panel 10 . There are multiple connection structures between the light-transmitting liquid cold plate 30 and the display panel 10. The first is to attach the light-transmitting liquid cold plate 30 to the light incident side of the display panel 10, that is, the side of the display panel 10 facing the backlight source 20. In this way, the light-transmitting liquid cold plate 30 absorbs heat from the light incident side of the display panel 10 to cool down the display panel 10. The second is to attach the light-transmitting liquid cold plate 30 to the light-emitting side of the display panel 10, that is, the side of the display panel 10 facing away from the backlight source 20. In this way, the light-transmitting liquid cold plate 30 absorbs heat from the light-emitting side of the display panel 10 to cool down the display. The third is to attach the light-transmitting liquid cold plate 30 to both the light incident side and the backlight side of the display panel 10. In this way, the light-transmitting liquid cold plate 30 absorbs heat from both sides of the display panel 10, which can improve the heat dissipation efficiency of the display panel 10.

[0048] like Figures 5 and 6As shown, in the embodiment of the present invention, the light-transmitting liquid cold plate 30 is attached to the light-emitting side of the display panel 10, and the side of the light-transmitting liquid cold plate 30 away from the display panel 10 is a concave surface or a convex surface. When the light-transmitting liquid cold plate 30 is attached to the light-emitting side of the display panel 10, the structure of the light-transmitting liquid cold plate 30 can also be changed. Specifically, the side of the light-transmitting liquid cold plate 30 away from the display panel 10 is designed to be a concave surface, forming a structure similar to a concave mirror; the side of the light-transmitting liquid cold plate 30 away from the display panel 10 can also be designed to be a convex surface, forming a structure similar to a convex mirror. The above structure can form special optical imaging characteristics on the display panel 10, enriching the display effect of the display.

[0049] like Figure 1 to Figure 2 As shown, in an embodiment of the present invention, the liquid-cooled display further includes a liquid pump 50 and a liquid infusion pipeline 510; a liquid inlet 310 and a liquid outlet 320 are formed on the light-transmitting liquid cold plate 30; the liquid pump 50 is connected to the liquid inlet 310 and the liquid outlet 320 through the liquid infusion pipeline 510. The liquid pump 50 can store light-transmitting cooling liquid 40, and can provide power to promote the circulation of the light-transmitting cooling liquid 40 in the cavity of the liquid infusion pipeline 510 and the light-transmitting liquid cold plate 30. The circulating light-transmitting cooling liquid 40 can accelerate the absorption of heat from the display panel 10, and avoid the accumulation of heat from the light-transmitting cooling liquid 40 and affect the heat absorption effect.

[0050] like Figure 1 to Figure 2 As shown, in an embodiment of the present invention, the liquid-cooled display further includes a radiator 511 suitable for the light-transmitting cooling liquid 40 to flow through, and the radiator 511 is connected to the infusion pipeline 510. A plurality of heat sink structures can be formed on the radiator 511, which is similar to the structure of a radiator. When the light-transmitting cooling liquid 40 that has undergone heat exchange flows through the radiator 511, the heat in the light-transmitting cooling liquid 40 can be dissipated in the radiator 511 to accelerate the cooling of the light-transmitting cooling liquid 40, so as to facilitate the next heat exchange. The radiator 511 can be made of metal.

[0051] like Figure 2 As shown, in the embodiment of the present invention, a heat dissipation fan 5111 is provided on the radiator 511, and the heat dissipation fan 5111 is suitable for providing heat dissipation wind force to the radiator 511. The heat dissipation fan 5111 can accelerate the air flow around the radiator 511, thereby accelerating the heat dissipation efficiency of the light-transmitting cooling liquid 40 in the radiator 511, so that the light-transmitting cooling liquid 40 can be quickly cooled. Furthermore, the heat dissipation fan 5111 can be an axial flow fan.

[0052] In an embodiment of the present invention, the circulation flow rate, circulation speed, circulation frequency, circulation time, etc. of the light-transmitting cooling liquid 40 can be controlled by the liquid pump 50, and the rotation speed and start and stop time of the cooling fan 5111 can also be controlled, thereby achieving precise heat dissipation control of the display panel 10.

[0053] like Figures 1 to 6 As shown, in an embodiment of the present invention, the liquid-cooled display further includes an optical glue 60; the light-transmitting liquid cold plate 30 is attached to the display panel 10 through the optical glue 60. The optical glue 60 has an adhesive function, and the light-transmitting liquid cold plate 30 is attached to the display panel 10 through the optical glue 60, which can ensure the bonding strength of the light-transmitting liquid cold plate 30, and avoid the generation of a gap between the light-transmitting liquid cold plate 30 and the display panel 10 after the light-transmitting liquid cold plate 30 is opened and closed, thereby affecting the heat conduction between the light-transmitting liquid cold plate 30 and the display panel 10.

[0054] The optical adhesive 60 not only has excellent adhesion, but also has excellent optical penetration performance, thermal conductivity and high temperature resistance, so that the heat of the display panel 10 can be quickly transferred to the light-transmitting cooling liquid 40 without almost losing optical performance.

[0055] In an embodiment of the present invention, the light-transmitting cooling liquid 40 includes a dimming agent. The light-transmitting cooling liquid 40 can be a single transparent substance, or a dimming agent can be added to the light-transmitting cooling liquid 40. The dimming agent can adjust the display effect to a certain extent, such as enhancing the uniformity of display brightness, blocking infrared light, blocking specific harmful blue light, etc., thereby improving the user's viewing experience.

[0056] In the embodiment of the present invention, the area of ​​the bonding surface of the light-transmitting liquid cold plate 30 is equal to the area of ​​the bonding surface of the display panel 10. The larger the bonding area between the light-transmitting liquid cold plate 30 and the display panel 10, the larger the heat absorption area of ​​the light-transmitting liquid cold plate 30 for the display panel 10, so that the heat of the display panel 10 can be absorbed over a large area, thereby improving the heat dissipation efficiency and heat dissipation effect of the display panel 10. In the embodiment of the present invention, the bonding surface of the light-transmitting liquid cold plate 30 is equal to the bonding surface of the display panel 10, that is, the light-transmitting liquid cold plate 30 is bonded to the entire heating surface of the display panel 10, so that heat absorption can be achieved without omission or dead angle, so that the light-transmitting cooling liquid 40 absorbs more heat per unit time, greatly accelerating the cooling speed of the display panel 10.

[0057] The second aspect of the present invention provides an interface interaction device, including the liquid-cooled display in any embodiment of the first aspect. The interface interaction device may include a projector, a mobile phone, a tablet, a computer, a television, an electronic display screen, etc. Such devices realize human-computer interaction and information transmission through a display.

[0058] According to the interface interaction device provided by the embodiment of the second aspect of the present invention, it includes a liquid-cooled display, and the liquid-cooled display uses liquid cooling to cool the display to achieve heat dissipation. Specifically, the display includes a display panel 10, a backlight source 20, and a light-transmitting liquid cold plate 30, wherein the backlight source 20 can emit light so that the display panel 10 can display an image, and a light-transmitting cooling liquid 40 is stored in the light-transmitting liquid cold plate 30, and the light-transmitting liquid cold plate 30 is integrally attached to the display panel 10, which is conducive to improving the heat conduction efficiency. Therefore, the heat in the display panel 10 can be directly and quickly transferred to the light-transmitting cooling liquid 40 in the light-transmitting liquid cold plate 30, and the light-transmitting cooling liquid 40 absorbs the heat of the display panel 10, thereby achieving rapid cooling of the display panel 10, with good heat dissipation effect and high heat dissipation efficiency. Both the light-transmitting liquid cold plate 30 and the light-transmitting cooling liquid 40 have a light-transmitting function and will not affect the image display effect of the display panel 10. The light-transmitting liquid cold plate 30 fits tightly against the display panel 10, thereby reducing the overall thickness of the display, optimizing the structure of the display, realizing a lightweight design of the display, and reducing design costs and maintenance costs, thereby reducing the volume and cost of the interface interaction device and improving product stability.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
