[0030] The utility model provides a three-dimensional vision liquid crystal display screen, which includes a TFT liquid crystal display screen, a PMOLED display screen and a touch cover plate, wherein the PMOLED display screen is arranged above the TFT liquid crystal display screen, and the touch cover plate is arranged above the PMOLED display screen, wherein the TFT liquid crystal display screen includes a TFT lower polarizer, a TFT lower substrate, a TFT upper substrate, and a TFT upper polarizer which are sequentially stacked from bottom to top, and the PMOLED display screen includes a PMO lower substrate, a PMO upper substrate, and a PMO upper polarizer which are sequentially stacked from bottom to top, wherein the PMO lower substrate, the PMO upper substrate, and the PMO upper polarizer are all made of transparent materials, and a plurality of grooves are formed on the upper surface of the touch cover plate by etching, and a plastic layer is covered on the upper side of the touch cover plate, and the plastic layer is embedded in the plurality of the grooves.
[0031] Since the PMOLED display is set above the TFT LCD display and all parts of the PMOLED display are made of transparent materials, the light of the TFT LCD display can pass through the PMOLED display into the user's eyes, and the PMOLED display can display independently, so that the TFT LCD display and the PMOLED display can display two layers of pictures in total.

[0032] In order to enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings. The present invention is described in detail below in conjunction with the accompanying drawings and embodiments, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limitations on the present invention.
[0033] Example 1
[0034] See also Figure 1 and Figure 2, a stereoscopic vision liquid crystal display screen provided by the utility model comprises a TFT liquid crystal display screen 1, a PMOLED display screen 2 and a touch cover plate 3, the PMOLED display screen 2 is arranged above the TFT liquid crystal display screen 1, and the touch cover plate 3 is arranged above the PMOLED display screen 2, the TFT liquid crystal display screen 1 comprises a TFT lower polarizer 11, a TFT lower substrate 12, a TFT upper substrate 13, and a TFT upper polarizer 14 which are sequentially stacked from bottom to top, the PMOLED display screen 2 comprises a PMO lower substrate 21, a PMO upper substrate 22, and a PMO upper polarizer 23 which are sequentially stacked from bottom to top, the PMO lower substrate 21, the PMO upper substrate 22, and the PMO upper polarizer 23 are all made of transparent materials, the upper surface of the touch cover plate 3 is covered with a plastic layer 4, the upper surface of the touch cover plate 3 is etched to form a plurality of grooves 31 downwardly, and a portion of the lower surface of the plastic layer 4 is embedded in each groove 31, and since the surface of the groove 31 formed by etching has a certain roughness, the plastic layer 4 can be tightly bonded to the groove 31 to prevent the touch cover plate 3 and the plastic layer 4 from falling off. Since the touch cover plate 3 is covered with a plastic layer 4, and a plurality of grooves 31 are formed on the upper surface of the touch cover plate 3 by etching, and the plastic layer 4 can be embedded in the plurality of grooves 31, the grooves 31 formed by etching make the inner surface of the grooves 31 have a certain degree of roughness, and the surface of the grooves 31 with a certain degree of roughness can improve the bonding force between the grooves 31 and the plastic layer 4, thereby reducing the possibility of separation of the grooves 31 and the plastic layer 4. When the LCD screen is hit or falls, the plastic layer 4 on the upper surface of the touch cover 3 can directly withstand the external force, thereby preventing the external force from directly acting on the touch cover 3. Since the plastic layer 4 can absorb most of the energy, the remaining external force is very weak when it acts on the touch cover 3, thereby effectively reducing the risk of the touch cover 3 being broken or damaged; and when the LCD screen is subjected to external force, even if the external force is large, it will only damage the plastic layer 4 on the upper surface of the touch cover 3, and will not directly damage the touch cover 3. Therefore, it can be avoided that the touch cover 3 is damaged and the LCD screen cannot be used normally, which brings a better user experience to the user and improves the anti-fall ability of the LCD screen.
[0035] See also Figures 2 to 4 Furthermore, the shape of the groove 31 can be square or circular, and the cross-sectional shape of the groove 31 can be a closing groove that is narrow outside and wide inside. In the present embodiment, the cross-sectional shape of the groove 31 is an isosceles trapezoid, and the groove 31 is in the shape of an elongated strip. The isosceles trapezoidal groove 31 can make the plastic layer 4 tightly embedded in the groove 31, avoiding the separation of the groove 31 and the plastic layer 4, thereby preventing the touch cover 3 and the plastic layer 4 from falling off. The elongated groove 31 can increase the fitting portion between the plastic layer 4 and the groove 31, thereby improving the fitting strength between the groove 31 and the plastic layer 4.
[0036] Furthermore, the plastic layer 4 in the visible area is transparent plastic to prevent the plastic layer 4 from affecting the normal display of the liquid crystal display screen. The plastic layer 4 in the non-visible area can be non-transparent plastic, which can be colorful, thereby improving the beauty of the liquid crystal display screen and enhancing the competitiveness of the product.
[0037] Example 2
[0038] See also Figure 5 and Figure 6 As a further optimization scheme of Example 1, in this embodiment, a PMO FPC 24 is bound to the PMO lower substrate 21, a TFT FPC 15 is bound to the TFT lower substrate 12, the PMO FPC 24 is connected to the TFT FPC 15, and the TFT FPC 15 is led out and bent to the main board.
[0039] Further, the TFT FPC15 includes a substrate layer 151, a circuit layer 152 disposed on the upper surface of the substrate layer 151, and a metal heat dissipation layer 153 disposed on the lower surface of the substrate layer 151, and the arrangement mode can be that the circuit layer 152 and the metal heat dissipation layer 153 are respectively attached to the substrate layer 151 by double-sided adhesive. Since the thickness of the substrate layer 151 is relatively thin, the heat on the TFT FPC15 can be diffused to the metal heat dissipation layer 153 through the substrate layer 151, and the metal heat dissipation layer 153 can effectively increase the heat dissipation area of the TFT FPC15, play a role in uniform heat dissipation, thereby improving the heat dissipation efficiency of the TFT FPC15. The substrate layer 151 can be any one of polyimide, polyester, polysulfone or polytetrafluoroethylene, the double-sided adhesive is any one of an acrylic adhesive layer or an epoxy resin adhesive layer, and the metal heat dissipation layer 153 can be a copper foil layer.
[0040] Furthermore, the TFT FPC 15 further includes at least one through-hole 154 penetrating the substrate layer 151, the circuit layer 152 and the metal heat dissipation layer 153, and the inner wall of the through-hole 154 is provided with a heat-conducting layer in contact with the circuit layer 152 and the metal heat dissipation layer 153. By utilizing the good thermal conductivity of the through-hole 154, the circuit layer 152 and the metal heat dissipation layer 153 on both sides of the substrate layer 151 can be electrically connected to play a good thermal conductivity function, and the thermal conductive layer can provide a thermal conductive function to achieve a good heat dissipation effect. Among them, the thermal conductive layer can be a copper glue conductive ink layer.
[0041] Furthermore, a heat conductor connected to an external heat-conducting structure is disposed in the through hole 154, and the heat conductor is connected to the external heat-conducting structure from one side of the circuit layer 152, and is also in contact with the heat-conducting layer in the through hole 154, so that the circuit layer 152 and the metal heat dissipation layer 153 can be connected to the external heat-conducting structure through the through hole 154, so that the heat in the TFT FPC 15 is diffused to the external heat-conducting structure through the heat conductor in the through hole 154, so as to further improve the heat dissipation efficiency of the TFT FPC 15. Preferably, in order to enable the through hole 154 to be connected to the external heat-conducting structure, the through hole 154 is disposed at the edge of the TFT FPC 15.
[0042] Furthermore, the metal heat dissipation layer 153 is a uniform heat dissipation structure, and its structure can be any one of a mesh structure, a strip structure, a wavy structure or a honeycomb structure. Through this uniform heat dissipation structure, the heat dissipation effect can be better improved.
