In the prior art, the red sub-pixel and the green sub-pixel almost completely absorb light of near ultraviolet short waves, the light frequency of the near ultraviolet short waves is larger than that of visible light, the energy is larger, a large amount of heat in the display module can be accumulated, the temperature is higher than that in the traditional visible light display, and the use instruction of the liquid crystal display panel can be influenced and the 3D printing quality can be influenced due to the fact that no scattering equipment specially aiming at the liquid crystal display panel is provided. In the technical solution of the embodiment of the present invention, the temperature control component 12 may be arranged to avoid the problem, and the implementation manner includes, but is not limited to, the manner shown in fig. 2.

Referring to fig. 2, fig. 2 is a schematic structural diagram of another display panel according to an embodiment of the present invention, in this way, the display panel is a liquid crystal display panel, and the display module 11 is a liquid crystal display module. The display module 11 may be provided with incident light as backlight by the backlight module. The backlight module is not shown in fig. 2.

In the lcd panel, the display module 11 includes a first substrate 21 and a second substrate 22 disposed opposite to each other, and a liquid crystal layer located between the first substrate 21 and the second substrate 22, which is not shown in fig. 2. Wherein, the temperature control component 12 is disposed on a side surface of the first substrate 21 facing away from the liquid crystal layer. The first substrate 21 has a pixel array including a plurality of sub-pixels arranged in an array.

					Thermal conductivity W/mK	142	237	401	0.75

Optionally, the material of the first reflective metal layer M1 includes any one or more of copper, aluminum, and molybdenum. Thus, the first reflective metal layer M1 can form a reflective surface with a higher reflectivity directly facing the surface of the incident light, and also has a higher heat conduction efficiency, so that the heat of the display module 11 can be conducted to the heat conduction member 13 more quickly, and then conducted to the heat dissipation module.

In the existing liquid crystal display module, the material is generally ITO, so that the heat conductivity coefficient is small, and the heat dissipation is inconvenient. As shown in the above table 1, the copper, the aluminum and the molybdenum have high thermal conductivity, so that the first reflective metal layer M1 can dissipate heat of the display module 11 quickly and improve the temperature uniformity of the light-side surface 112 of the heat dissipation module 11, thereby avoiding over-high local temperature.

When the display panel is a liquid crystal display panel, the display panel further includes a first polarizer 32 and a second polarizer 31, and the display module 11 is located between the first polarizer 32 and the second polarizer 31.

As shown in fig. 2, a first polarizer 32 is attached and fixed to a surface of the first reflective metal layer M1 facing away from the display module 11, and a second polarizer 31 is attached and fixed to the display side surface 111. The first reflective metal layer M1 is disposed between the display module 11 and the first polarizer 32, so that the liquid crystal display module 11 directly contacts with the first reflective metal layer M1, and the heat of the display module 11 is quickly conducted to the heat sink module through the metal component.

In the lcd panel, the display module 11 includes a plurality of sub-pixels arranged in an array, and a pixel gap is formed between adjacent sub-pixels for disposing opaque elements such as pixel tfts, gate lines, and data lines. In a conventional lcd panel, the light emitted from the backlight module is a surface light source, and completely irradiates the entire light incident side surface 112. In the embodiment of the present invention, the temperature control component 12 at least blocks the pixel gap, so as to prevent light from irradiating the pixel gap of the display module 11, thereby preventing the pixel gap from being heated due to light irradiation. When the liquid crystal display panel is used in a 3D printer, the temperature control component 12 is further configured to shield at least a partial region of the red sub-pixel R and/or at least a partial region of the green sub-pixel G, so as to further avoid a temperature increase of the display module 11 caused by light that does not pass through the display module 11.

In the embodiment of the invention, when the display panel is a liquid crystal display panel, the temperature control component 12 can be reused as a polarizer, so that a polarizer does not need to be arranged on one side of the display module 11 facing the backlight module, the thickness of the panel is reduced, and the cost is reduced. At this time, the structure of the display panel is as shown in fig. 4.

As shown in fig. 4 and the right view of fig. 5, in the embodiment of the invention, the first metal wire grid polarizer 41 includes a second reflective metal layer M2, the second reflective metal layer M2 includes a first central area a1 and a first peripheral area B1 surrounding the first central area a1, the first central area a1 includes a plurality of first light-shielding bars a11 and a plurality of first hollow bars a12, the first light-shielding bars a11 and the first hollow bars a12 are alternately distributed and parallel to each other, and the first hollow bars a12 serves as the light-transmitting window 121. The first peripheral region B1 and the first light-shielding bars a11 serve as the light-shielding portion 122.

The temperature control component 12 further includes a transparent substrate 42, and the second metal layer M2 is disposed on the surface of the transparent substrate 42. The transparent substrate 42 has an adhesive layer on a side surface thereof facing away from the second metal layer M2 for being attached and fixed to the light incident side surface 112 of the display module 11. The first metal wire grid polarizer 41 may be manufactured by a nano-imprint technique. The first metal wire grid polarizer 41 is a reflection type metal wire grid polarizer, and the light irradiated to the first shading grid a11 is reflected instead of absorbed, reducing the accumulation of heat on the surface of the temperature control member 12.

The left image in fig. 5 is a top view of a conventional metal wire grid polarizer, and the metal layer M includes a plurality of alternately distributed hollow grid bars a1 and light-shielding grid bars a 2. The first metal wire grid polarizer 41 according to the embodiment of the invention has a structure different from the conventional metal wire grid polarizer, and has a first peripheral region B1 surrounding a first central region a1, and each first shading grid bar a11 and the first peripheral region B1 are integrated into a whole. The first peripheral area B1 is used for fixedly connecting a heat conducting member, so that the temperature control member 12 can be conveniently connected to the heat dissipation module through the heat conducting member 13, and the heat generated by the light irradiation of the backlight module can be conveniently and rapidly conducted to the heat dissipation module. The backlight module comprises the UV-LED (light source device emitting the short wave).

In the display panel according to the embodiment of the invention, the first metal wire grid polarizer 41 is used as the temperature control component 12, so that on one hand, the function of the polarizer can be realized, and the polarizer does not need to be arranged on the light incident side alone, and on the other hand, the high heat conduction characteristic of the metal material can be reused, so that the heat of the display module 11 can be quickly conducted to the heat dissipation module, and the temperature uniformity of the light incident side surface 112 of the display module 11 can be improved. Moreover, the first light-shielding grid bars a11 and the first hollow grid bars a12 in the first metal wire grid polarizer 41 can be arranged in a size, so that the first light-shielding grid bars a11 can shield and reflect light rays in a specific area, the light rays in the area are prevented from being incident into the display module 11, and heat accumulation caused by the light rays which do not need to penetrate through the display module 11 and enter into the display module 11 is avoided. The special area comprises at least one of the following three modes: firstly, at least part of a pixel gap; II, at least part of the red sub-pixel R; and thirdly, at least part of the green sub-pixel G.

In the embodiment of the present invention, the display module 11 includes a plurality of sub-pixels, a plurality of gate lines, and a plurality of data lines; the gate lines and the data lines are crossed to define a plurality of pixel areas, and each pixel area is correspondingly provided with one sub-pixel; the gate lines and the data lines are used for driving the sub-pixels to display images; the data lines and/or the gate lines are copper lines to increase thermal conductivity and reduce electrical resistivity.

Compared with the conventional electronic device for visible light display, the requirement for the aperture ratio of the green sub-pixel G and the red sub-pixel R is reduced, and a copper wire process with a large width can be prepared with low precision to be used as the data wire and/or the gate wire. In the existing liquid crystal display panel, the data lines and the gate lines adopt molybdenum-aluminum-molybdenum structures, a high-precision manufacturing process is needed to prepare smaller line width, the cost is higher, and the used material has smaller thermal conductivity and larger resistivity. Compared with the existing wiring mode of a molybdenum-aluminum-molybdenum structure, the technical scheme of the invention can improve the heat conduction efficiency by 1-2 times, effectively improve the heat transfer in the display module 11 and ensure that the heat is uniformly distributed. Referring to fig. 6, fig. 6 is a schematic structural diagram of another display panel according to an embodiment of the present invention, in this way, a second metal wire grid polarizer 51 is disposed on a display side surface 111 of the display module 11.

Also, the second metal wire grid polarizer 51 may be manufactured through a nano-imprinting process. The second metal wire grid polarizer 51 includes a transparent substrate 52. The second metal wire grid polarizer 51 is made of a metal material and has high thermal conductivity, so that the temperature uniformity of the display side surface 111 of the display module 11 can be improved, and the problem of local high temperature can be avoided.

Optionally, the third reflective metal layer M3 is connected to the heat conducting member 13, so that the heat of the display module 11 can be conducted to the heat dissipation module through the second metal wire grid polarizer 51 and the heat conducting member 13 on the display side surface 11, thereby increasing the heat dissipation rate. A metal sheet 53 may be fixed at a second peripheral region of the second wire grid polarizer 51 to be connected to the copper pipe 132.

In the embodiment shown in fig. 6, both the first polarizer 32 and the second polarizer 31 are metal wire grid polarizers, and in other embodiments, only the first polarizer 32 may be a metal wire grid polarizer, or only the second polarizer 31 may be a metal wire grid polarizer.
