Three-dimensional stereoscopic display is an attractive frontier area of technology today.

However, when the touch function is needed to be realized by the existing naked-eye 3D display screen, a layer of touch screen needs to be overlapped on the surface, which not only increases the complexity of the display screen device, makes the manufacturing steps cumbersome, but also causes the thickness to be too thick, and affects the heat dissipation effect.

The invention provides a display screen.
In an embodiment of the present invention, as shown in fig. 1, the display panel includes a liquid crystal module 100 and a composite functional layer 200 stacked together;
wherein the composite functional layer 200 comprises:
the first light-transmitting substrate 210 is arranged close to the liquid crystal module 100, and one side, away from the liquid crystal module 100, of the first light-transmitting substrate 210 is sequentially provided with an ITO conductive film layer 220, a preformed lens layer 230, a liquid crystal layer 240 and an ITO touch sensing layer 250 in a stacked mode; and
and the second light-transmitting substrate is arranged on one side of the ITO touch sensing layer 250, which is far away from the preformed lens layer 230.
It can be understood that the liquid crystal module 100 is used for two-dimensional planar display, and the composite functional layer 200 can be used for three-dimensional stereoscopic display and can also realize a touch function. Specifically, the first light-transmitting substrate 210 in the composite functional layer 200 is used for connecting with the liquid crystal module 100; the ITO conductive film layer 220 is used for controlling liquid crystal deflection in the liquid crystal layer 240; the pre-lens layer 230 is used to refract light from the liquid crystal layer 240 to implement three-dimensional stereoscopic display; the ITO touch sensing layer 250 is used for realizing the touch function of the display screen; the second light-transmitting substrate is arranged on the outermost side to protect the inner layer structure of the display screen.
In the prior art, when the touch function of the 3D display screen is realized, a layer of touch screen needs to be superimposed on the basis of the 3D display screen, and the layer of touch screen not only can increase the complexity of the device of the display screen, so that the manufacturing steps of the display screen are more complicated, but also can cause the over-thick thickness of the display screen, thereby affecting the heat dissipation effect of the display screen.
In the present invention, the ITO touch sensing layer 250 is sandwiched between the preformed lens layer 230 of the composite functional layer 200 and the second transparent substrate, so that a user can touch the second transparent substrate to perform a touch operation on the display screen, and the added ITO touch sensing layer 250 has almost no thickness, which does not increase the thickness of the display screen, and thus does not affect the heat dissipation effect of the display screen. In addition, because the ITO touch sensing layer 250 is disposed in the composite functional layer 200, during production, only the ITO touch sensing layer 250 needs to be added into the composite functional layer 200, so that the step of producing a touch screen can be omitted, the production cost of the display screen is reduced, and the production efficiency of the display screen is also improved.
Further, in the present embodiment, the liquid crystal module 100 is a high resolution liquid crystal module. It can be understood that when the composite functional layer 200 is used for three-dimensional stereoscopic display, the resolution is easily lost, so that the liquid crystal module adopts the high-resolution liquid crystal module 100 (such as a liquid crystal module with a resolution of 4K or 8K), the lost resolution can be properly compensated, and in addition, the display screen can display a high-definition 2D picture when two-dimensional planar display is performed, so that three-dimensional display content and two-dimensional display content can be more clearly transmitted to viewers.
Further, in this embodiment, the composite functional layer 200 is fully attached to the liquid crystal module 100 through the optical adhesive 300. The composite functional layer 200 and the liquid crystal module 100 are bonded together by full lamination, and particularly, in order to enable the composite functional layer 200 to perform three-dimensional stereoscopic display, the thickness of the optical adhesive 300 between the two should be determined by referring to the focal length of the preformed lens, so that the pixel display unit of the liquid crystal module 100 can be positioned near the focal plane of the preformed lens. Because the optical cement 300 fills the gap between the first transparent substrate 210 and the liquid crystal module 100, no air exists between the first transparent substrate and the liquid crystal module, the light reflection can be greatly reduced, the loss of the transmitted light is reduced, the brightness is improved, and the display effect of the screen is enhanced. Moreover, the first light-transmitting substrate 210 under the full-lamination is tightly laminated with the liquid crystal module 100, dust and water vapor do not have places to enter, the dust and the water vapor can be isolated, the cleanliness of the screen is kept, and therefore the display effect of the display screen is guaranteed.
Further, in the present embodiment, the preformed lens layer 230 includes a plurality of inclined cylindrical lens units 231 distributed in an array. The inclined cylindrical lens units can transfer part of loss of resolution in the horizontal direction in three-dimensional stereoscopic display to the vertical direction, so that a three-dimensional picture is clearer and more harmonious; meanwhile, the interference between the cylindrical lens units and the liquid crystal pixels can be reduced, so that the mole fringes are relieved.
Further, in this embodiment, the sensing pattern 251 shown in fig. 2 is disposed on the surface of the ITO touch sensing layer 250, where the sensing pattern 251 includes a plurality of longitudinal sensing pattern units 251a distributed in a transverse array, the inclined cylindrical lens units 231 are distributed in a transverse array, a plurality of the longitudinal sensing pattern units 251a are disposed corresponding to one of the inclined cylindrical lens units 231, or one of the longitudinal sensing pattern units 251a is disposed corresponding to a plurality of the inclined cylindrical lens units 231. The sensing pattern 251 is used for sensing a touch signal of a finger, and includes a plurality of longitudinal sensing pattern units 251a distributed in a transverse array and a plurality of transverse sensing pattern units 251b distributed in a longitudinal array to form a two-dimensional sensing system, thereby achieving a multi-touch effect. Without loss of generality, the longitudinal sensing pattern units 251a and the transverse sensing pattern units 251b in this embodiment are formed by connecting a plurality of diamond patterns in series, and the axes of the plurality of diamond patterns included in each longitudinal sensing pattern unit 251a and each transverse sensing pattern unit 251b are all located on the same straight line, so that each longitudinal sensing pattern unit 251a and each transverse sensing pattern unit 251b are integrated on the same ITO film layer in a staggered distribution manner, the thickness of the display screen can be further reduced, and the cost is further saved.
Since the tilted cylindrical lens units 231 in this embodiment are distributed in a horizontal array, in order to reduce the interference between the pre-fabricated lens layer 230 and the ITO touch sensing layer 250, the ratio of the array distribution period of the tilted cylindrical lenses in the pre-fabricated lens layer 230 to the array distribution period of the longitudinal sensing pattern units 251a of the ITO touch sensing layer 250 should be an integer or the reciprocal of the integer, and when the ratio is an integer, a plurality of longitudinal sensing pattern units 251a should be arranged corresponding to one tilted cylindrical lens unit 231 (as shown in fig. 2); when the ratio is the reciprocal of an integer, a longitudinal sensing pattern unit 251a is disposed corresponding to the plurality of inclined cylindrical lens units 231 (not shown), so as to achieve the purpose of reducing moire fringes and further improve the display effect of the display screen.
Of course, in other embodiments, the tilted cylindrical lens units 231 may be distributed in a longitudinal array, and correspondingly, in order to reduce the interference between the pre-lens layer 230 and the ITO touch sensing layer 250, a plurality of transverse sensing pattern units 251b should be disposed corresponding to one tilted cylindrical lens unit 231, or one transverse sensing pattern unit 251b should be disposed corresponding to a plurality of tilted cylindrical lens units 231, which can also achieve the purpose of reducing the moire fringes.
Further, in this embodiment, as shown in fig. 2, the longitudinal sensing pattern units 251a are obliquely arranged on the surface of the ITO touch sensing layer 250, and the oblique direction of the longitudinal sensing pattern units 251a is parallel to the oblique direction. When the longitudinal sensing pattern unit 251a is parallel or substantially parallel to the tilted cylindrical lens unit 231, the corresponding relationship between the longitudinal sensing pattern unit 251a and the tilted cylindrical lens unit 231 described above can be realized without additional actions when the pre-fabricated lens layer 230 and the ITO touch sensing layer 250 are assembled, and the foolproof performance of the display in production and manufacturing is greatly improved. Of course, in other embodiments, the longitudinal sensing pattern unit 251a may not be disposed obliquely, and only by disposing the positioning marks on the pre-fabricated lens layer 230 and the ITO touch sensing layer 250, respectively, to avoid the crossing between the longitudinal sensing pattern unit 251a and the oblique cylindrical lens unit 231, the foolproof design for assembling the two units can be achieved.
Further, in this embodiment, a trace pattern 252 shown in fig. 3 is disposed on a surface of the ITO touch sensing layer 250, where the trace pattern 252 includes a plurality of longitudinal trace pattern units 252a distributed in a transverse array, the inclined lenticular lens units 231 are distributed in a transverse array, and a plurality of the longitudinal trace pattern units 252a are disposed corresponding to one of the inclined lenticular lens units 231. The trace pattern 252 is used for laying metal traces, and includes a plurality of longitudinal trace pattern units 252a distributed in a transverse array and a plurality of transverse trace pattern units 252b distributed in a longitudinal array, so as to improve the response efficiency of touch control. Since the trace patterns 252 are also periodically distributed, the ITO touch sensing layer 250 interferes with the lens array layer to generate moire fringes, which affects the display effect of the display screen. Since the tilted cylindrical lens units 231 in this embodiment are distributed in a horizontal array, in order to alleviate the moire phenomenon, the ratio of the array distribution period of the tilted cylindrical lenses in the pre-lens layer 230 to the array distribution period of the longitudinal trace pattern units 252a should be an integer or the reciprocal of the integer, and when the ratio is an integer, the plurality of longitudinal trace pattern units 252a should be arranged corresponding to one tilted cylindrical lens unit 231 (as shown in fig. 3); when the ratio is the reciprocal of an integer, a longitudinal trace pattern unit 252a is disposed corresponding to the plurality of inclined lenticular lens units 231 (not shown), so as to achieve the purpose of reducing moire fringes and further improve the display effect of the display panel.
Of course, in other embodiments, the slanted pillar lens units 231 may be distributed in a vertical array, and correspondingly, in order to further reduce the interference between the pre-lens layer 230 and the ITO touch sensing layer 250, a plurality of horizontal trace pattern units 252b should be disposed corresponding to one slanted pillar lens unit 231, or one horizontal trace pattern unit 252b should be disposed corresponding to a plurality of slanted pillar lens units 231, so as to also reduce the occurrence of moire fringes.
Further, in this embodiment, as shown in fig. 3, the longitudinal trace pattern units 252a are obliquely arranged on the surface of the ITO touch sensing layer 250, and the oblique direction of the longitudinal trace pattern units 252a is parallel to the oblique direction of the oblique cylindrical lens units 231, so as to further improve the foolproof performance when the pre-fabricated lens layer 230 and the ITO touch sensing layer 250 are assembled. Certainly, in other embodiments, the longitudinal trace pattern unit 252a may not be disposed obliquely, and only by disposing the positioning marks on the pre-fabricated lens layer 230 and the ITO touch sensing layer 250 respectively, the longitudinal trace pattern unit 252a and the oblique cylindrical lens unit 231 are prevented from being crossed, so that the foolproof design of assembling the two units can be implemented.
Further, in the present embodiment, the ITO touch sensing layer 250 is a touch sensing layer or a resistive touch sensing layer. The resistive touch sensing layer is low in cost, the capacitive touch sensing layer is high in cost, and the performances such as light loss, power consumption and service life of the capacitive touch sensing layer are superior to those of the resistive touch sensing layer. The capacitance type touch sensing layer and the resistance type touch sensing layer have advantages and disadvantages respectively, and different types of ITO touch sensing layers can be selected according to actual requirements in production.
The present invention further provides a display device, which includes a display screen, and the specific structure of the display screen refers to the foregoing embodiments, and since the display device adopts all technical solutions of all the foregoing embodiments, the display device at least has all beneficial effects brought by the technical solutions of the foregoing embodiments, and details are not repeated herein.
