Among various transparent display technology routes, Liquid Crystal Display (LCD) technology has attracted attention because of its mature technology and its easy mass production. In order to improve the transmittance of the Liquid Crystal display, the Polymer Network Liquid Crystal (PNLC) technology has attracted much attention because it can replace the polarizer to function as an optical switch. PNLC utilizes the difference in refractive index between liquid crystal molecules and macromolecules. When no voltage is applied, a scattering state is presented due to the difference of the refractive indexes of the two. When voltage is applied, the liquid crystal turns, the refractive index of the liquid crystal is matched with that of the polymer, and the liquid crystal is in a transparent state. At present, there is a transparent display method for realizing full color by combining PNLC with field sequence. However, the realization of full color by the field sequential method puts high demands on the response speed of liquid crystal and the charging speed of TFT, and it is difficult to realize a full-color large-size transparent display.

The embodiments of the present application provide a display panel, a method for manufacturing the display panel, and a display device, and the display panel is described in detail below.
Referring to fig. 1, fig. 1 is a first structural schematic diagram of a display panel 10 according to an embodiment of the present disclosure. The display panel includes a light guide plate 101, a liquid crystal cladding 102, an electric field circuit 103, a glass cover plate 104, a quantum dot film layer 105, and a light source 106. The light guide plate 101 includes a first surface 101a and a second surface 101b disposed opposite to each other. The liquid crystal cladding layer 102 is provided on the first face 101 a. The electric field circuit 103 is connected to the liquid crystal cladding 102 and generates an electric field for adjusting the refractive index of the liquid crystal cladding 102. The glass cover plate 104 is disposed on the side of the liquid crystal cladding 102 away from the first face 101 a. The quantum dot film layer 105 is disposed on a side of the glass cover plate 104 away from the liquid crystal cladding layer 102 or a side of the glass cover plate 104 close to the liquid crystal cladding layer 102. The light source 106 is disposed at a side surface of the light guide plate 101. In the display panel 10, the electric field circuit 103 is arranged on the side of the liquid crystal cladding layer far away from the first surface, and the electric field circuit 103 generates an electric field to adjust the refractive index of the liquid crystal cladding layer 102, so that the display function is realized while the high transmittance is maintained, and the purpose of transparent display is achieved. Meanwhile, full-color display can be realized by using the quantum dot film layer 105 arranged on the glass cover plate 104.
The first surface 101a may be an upper surface of the light guide plate 101, and the second surface 101b may be a lower surface of the light guide plate 101. Of course, the first surface 101a may be a lower surface of the light guide plate 101, and the second surface 101b may be an upper surface of the light guide plate 101. In the embodiment of the present application, it is assumed that the first surface 101a is the upper surface of the light guide plate 101 and the second surface 101b is the lower surface of the light guide plate 101 without specific description.
The light guide plate 101 is one or a combination of optical glass, a polymethyl methacrylate (PMMA) light guide plate, and a Polycarbonate (PC) light guide plate. The light guide plate 101 has a very high refractive index and does not absorb light, and can control light well while the light utilization rate is high.
The liquid crystal cladding 102 is formed by laminating one layer of liquid crystal 1021 or two or more layers of liquid crystal 1021, and the arrangement direction of the liquid crystal 1021 in the liquid crystal cladding 102 is changed by the influence of an electric field, so that the arrangement direction of the liquid crystal 1021 is changed by the applied electric field, and the refractive index of the liquid crystal 1021 is changed accordingly. Wherein, the liquid crystal cladding 102 is provided with positive liquid crystal or negative liquid crystal. Under the action of the electric field, the long axis of the liquid crystal molecules is parallel to the electric field and is positive liquid crystal, and the long axis is vertical to the electric field and is negative liquid crystal. The negative liquid crystal has uniform twist angle distribution and high penetration rate. The positive liquid crystal has short response time under the action of an electric field, high liquid crystal purity and difficult product defect generation. In addition, the positive liquid crystal or the negative liquid crystal is arranged, so that the difference between a normally black mode and a normally white mode is generated in the liquid crystal display mode, and therefore, the positive liquid crystal or the negative liquid crystal can be arranged in different areas according to the adjustment requirement of brightness of the panel, and transparent display is realized.
Referring to fig. 2, fig. 2 is a schematic diagram illustrating a second structure of the display panel 10 according to the embodiment of the present disclosure. The quantum dot film layer 105 comprises a red quantum dot film layer 1051 and a green quantum dot film layer 1052 which are adjacently arranged, the quantum dot film layer 105 is partially connected with the glass cover plate 104, and the light source 106 is a blue light source. The glass cover plate 104 can play a role in dust prevention and water prevention without influencing the light ray emergence, and can also protect the display panel. The quantum dot film layer 105 can excite the red quantum dots 1051 and the green quantum dots 1052 by using a blue light source to realize full-color display, and the blue light source is adopted to excite the quantum dots to emit light, so that various problems caused by different service lives of colors are not worried about, the manufacturing cost is cheaper than that of a whole self-luminous screen, and higher color gamut can be realized by virtue of the high color purity advantage of the quantum dots.
The display panel 10 further includes a transparent conductive film 107, the transparent conductive film 107 is disposed on a side of the liquid crystal cladding 102 away from the first surface 101a, and the electric field circuit 103 is electrically connected to the transparent conductive film 107. By providing the transparent conductive film 107, the arrangement direction of the liquid crystal in the liquid crystal cladding 102 can be finely controlled by regions, and the refractive index of the liquid crystal can be controlled. The transparent conductive film 107 is used for finely controlling the liquid crystal cladding layer 102 in different regions, so that the brightness of the display panel 10 can be adjusted in a targeted manner, and large-size transparent display can be realized. The transparent conductive film 107 is made of Indium Tin Oxide (ITO). The ITO conductive glass has good conductivity and transparency, is small in thickness, and does not influence the overall thickness of the display panel. Meanwhile, the ITO conductive glass can also reduce electronic radiation, ultraviolet light and infrared light which are harmful to human bodies.
Referring to fig. 3, fig. 3 is a schematic structural diagram of a display panel 10 according to an embodiment of the present disclosure. The transparent conductive films 107 include at least two, the liquid crystal cladding 102 has at least two liquid crystal regions 108, and the liquid crystal regions 108 correspond to the transparent conductive films 107 one to one. Each transparent conductive film 107 is connected with an electric field circuit 103, and the electric field circuit 103 generates a vertical electric field or a horizontal electric field. The electric field circuit 103 is a flexible circuit board, a rigid circuit board, or other circuits.
The light source 106 is disposed on any one side of the light guide plate, and the light source 106 includes a Cold light (EL) source, a Cold Cathode Fluorescent Lamp (CCFL) source, and a light emitting diode (led)A (Light Emitting Diode, LED) Light source, an Organic Light-Emitting Diode (OLED) Light source, or an illumination Light source. The light source 106 is a blue collimated light source, and the light source enters the light guide plate 101 in the form of collimated light through the adjustment of the collimating lens, and the refractive index of the light guide plate 101 is larger than that of the liquid crystal cladding 102. The angle of incidence of the light source 106 is greater than the angle of total reflection of the liquid crystal cladding 102. Specifically, the angle of total reflection θ of the liquid crystal cladding 1020Calculated by the following formula:
θ0＝α·sin(n0/n)
θ0: the angle of total reflection of the liquid crystal cladding 102; n is0The refractive index of the liquid crystal, n the refractive index of the light guide plate, and α the reflection coefficient.
Referring to fig. 4, fig. 4 is a schematic view of a light refraction of the display panel 10 according to the embodiment of the present disclosure. The black arrows in fig. 4 represent light rays. When the incident angle theta of the light source 106 is larger than the total reflection angle theta of the liquid crystal cladding 1020At this time, since the refractive index of the light guide plate 101 is greater than that of the liquid crystal cladding 102, the light of the side-entry collimated light source is totally reflected in the light guide plate 101 and is confined in the light guide plate 101 for propagation. When an electric field is applied to the liquid crystal cladding 102 (exemplified in fig. 4 by arranging the transparent conductive film 107 to be connected to the electric field circuit 103 to generate an electric field), the effective refractive index n of the liquid crystaleffectiveIncrease by neffectiveN substituted into the above formula0When the critical reflection angle θ' of the liquid crystal cladding 102 is calculated and is greater than the incident angle θ of the light source 106, a portion of light will leak from the light guide plate 101, so that the display panel is bright, and large-size transparent display is realized. Full-color display can be realized by color conversion of the quantum dot film layer 105.
The display panel 10 provided in the embodiment of the present application includes a light guide plate 101, a liquid crystal cladding 102, an electric field circuit 103, a glass cover plate 104, a quantum dot film layer 105, a light source 106, and may further include a transparent conductive film 107. The transparent conductive film 107 is used for dividing the liquid crystal cladding layer 102 into liquid crystal regions 108 corresponding to the transparent conductive film 107, and the electric field circuit 103 connected with the transparent conductive film 107 is adjusted to adjust the orientation of liquid crystals in each liquid crystal region 108, so as to adjust the refractive index of the liquid crystals, adjust the brightness of different pixels and achieve the purpose of displaying.
