Detailed Description
Reference will now be made in detail to the exemplary embodiments of the present invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings and the description to refer to the same or like parts.
Fig. 1 is a schematic cross-sectional view of a display device according to an embodiment of the invention. Referring to fig. 1, in the present embodiment, a display device 100a includes a display 110a and a transflective module 120a. The transflective module 120a is disposed on one side of the display 110a, and includes a glass substrate 122 and a transflective structure layer 124. The transflective structure layer 124 is disposed on the glass substrate 122 and between the glass substrate 122 and the display 110a.
In detail, in the present embodiment, the display 110a is, for example, a thin film transistor-liquid crystal (TFT-LCD) display, an Organic Light Emitting (OLED) display, a Micro light emitting diode (Micro LED) display, or a sub-millimeter light emitting diode (Mini LED) display, which is not limited thereto. The front projection of the display 110a on the glass substrate 122 is less than or equal to the front projection of the transflective structure layer 124 on the glass substrate 122. In one embodiment, the transflective structure layer 124 may be, for example, a half-reflective mirror. In another embodiment, the transflective layer 124 may be made of transparent non-conductive material, and sputtered with high refractive material and low refractive materialThe half-penetration half-reflection layers are formed by overlapping modes, wherein the penetration rate of the half-penetration half-reflection layer is 30 percent, and the reflectivity is 70 percent; alternatively, the transmittance is 40% and the reflectance is 60%; alternatively, the transmittance is 50% and the reflectance is 50%. Here, the non-conductive material is, for example, aluminum, chromium, tin, nickel, silicon or other suitable material, and the high refractive material is, for example, silicon dioxide, magnesium fluoride (MgF) 2 ) Sodium fluoroaluminate (Na) 3 AlF 6 ) Or other suitable material, and low refractive materials such as titanium dioxide (TiO 2 ) Niobium pentoxide (Nb) 2 O 5 ) Tantalum pentoxide (Ta) 2 O 5 ) Zinc oxide (ZnO), silicon nitride (Si 3 N 4 ) Or other suitable material.
In addition, the transflective module 120a of the present embodiment further includes a frame 123. The glue frame 123 is disposed between the display 110a and the transflective structure layer 124 to fix the display 110a and the transflective module 120a. The frame 123, the display 110a and the transflective layer 124 define a space S1, and air is present in the space S1. Here, the material of the glue frame 123 includes epoxy or optical glue, but is not limited thereto.
In this embodiment, the transflective structure layer 124 of the transflective module 120a is disposed on the inner side of the glass substrate 122, i.e. relatively far from the user U, but relatively close to the display 110a. The distance between the transflective structure layer 124 and the display 110a is shorter in this embodiment than in the prior art in which a layer of opaque conductive material (e.g., a chrome layer) is placed in front of the cover glass (i.e., between the user and the cover glass). When the user U views the display 110a from the transflective module 120a, the distance between the light L1 reflected from the display 110a and the light L2 reflected from the display 110a via the transflective structure layer 124 is smaller, so that the ghost image can be effectively reduced or avoided. In this way, the display device 100a of the present embodiment can have better display quality. In addition, the material of the transflective structure layer 124 may be a non-conductive material and disposed on the inner side of the glass substrate 122, so as to have better weather resistance.
It should be noted that the following embodiments use the element numbers and part of the content of the foregoing embodiments, where the same numbers are used to denote the same or similar elements, and descriptions of the same technical content are omitted. For the description of the omitted parts, reference is made to the foregoing embodiments, and the following embodiments are not repeated.

In short, the transflective module 120c of the present embodiment further includes a touch sensing layer 126 as an input of the man-machine interface, wherein the transflective structure layer 124 made of a non-conductive material is located between the touch sensing layer 126 and the glass substrate 122, and does not affect the touch sensing of the touch sensing layer 126. In addition, the transflective structure layer 124 is disposed on the inner side of the glass substrate 122, so as to reduce or prevent the display device 100c from generating ghost images, and also increase the weather resistance of the transflective structure layer 124.
Fig. 4A is a schematic cross-sectional view of a display device according to another embodiment of the invention. Fig. 4B is a schematic cross-sectional view of the touch module in fig. 4A. Fig. 4C is a schematic cross-sectional view of another touch module according to an embodiment of the invention. Referring to fig. 1 and fig. 4A, the display device 100d of the present embodiment is similar to the display device 100a of fig. 1, and the difference between them is that: in this embodiment, the transflective module further includes a touch module 128 and an optical adhesive layer 127. The optical adhesive layer 127 is disposed on the transflective structure layer 124, wherein the transflective structure layer 124 is located between the optical adhesive layer 127 and the glass substrate 122. The touch module 128 is fixed on the transflective structure layer 124 through the optical adhesive layer 127. As shown in fig. 4B, the touch module 128 of the present embodiment is composed of a substrate 128a and an electrode layer 128B disposed on one side of the substrate 128a, wherein the substrate 128a is, for example, a glass substrate or a plastic substrate, and the electrode layer 128B is, for example, indium tin oxide. That is, the touch module 128 is a single-layer indium tin oxide (single indium tin oxide, SITO) electrode structure layer. In another embodiment, referring to fig. 4C, the touch module 128 'is composed of a substrate 128a and two electrode layers 128b and 128C disposed on opposite sides of the substrate 128a, i.e. the touch module 128' is a double-layer indium tin oxide (double indium tin oxide, DITO) electrode structure layer. In another embodiment, the touch module may be arranged into an electrode layer by a double-layer metal mesh (mesh), which is still within the scope of the present invention. In addition, the frame 123 is disposed between the display 110a and the touch module 128 to fix the display 110a and the transflective module 120d. The frame 123, the display 110a and the touch module 128 define a space S4, and air exists in the space S4.
Fig. 5 is a schematic cross-sectional view of a display device according to another embodiment of the invention. Referring to fig. 1 and fig. 5, the display device 100f of the present embodiment is similar to the display device 100a of fig. 1, and the difference between them is that: the display device 100f of the present embodiment further includes an optical adhesive layer 130 disposed between the display 110a and the transflective module 120f, wherein the display 110a and the transflective module 120f are bonded together through the optical adhesive layer 130. Here, the optical adhesive layer 130 is completely adhered to the surfaces of the display 110a and the transflective structure layer 124, that is, the present embodiment has no air layer between the display 110a and the transflective module 120 f.
It should be noted that the display devices 100a, 100b, 100c, 100d, 100f of the present embodiment also have the mirror function due to the semi-transmissive and semi-reflective modules 120a, 120c, 120d, 120 f. Therefore, the display devices 100a, 100b, 100c, 100d, 100f of the present embodiment may also incorporate a photosensitive device according to the difference of ambient light intensity, so as to automatically adjust the brightness of the display devices 100a, 100b, 100c, 100d, 100f in a sensing manner, so that the user U can see the image with an optimal contrast, and the display devices 100a, 100b, 100c, 100d, 100f can have an optimal contrast.
In summary, in the design of the display device of the present invention, the transflective structure layer of the transflective module is located between the glass substrate and the display, i.e. in the side of the glass substrate relatively far from the user (i.e. at the rear side). Therefore, compared with the prior art that the opaque conductive material layer is arranged in front of the protective glass, the distance between the light reflected from the display and the light reflected directly from the display after the light is reflected again by the semi-transparent semi-reflective structure layer is smaller, and the generation of the ghost can be effectively reduced or avoided. Therefore, the display device of the invention has better display quality.
Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present invention, and not for limiting the same; although the invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some or all of the technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the invention.
