Among various transparent Display technologies, Liquid Crystal Display (LCD) technology has attracted attention because of its characteristics such as mature technology and ease of 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.

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 requires high response speed of liquid crystal and charging speed of Thin Film Transistor (TFT), and it is difficult to realize large-size transparent display.

The appearances of the same phrases in various places in the specification are not necessarily limited to the same embodiment, but are to be construed as independent or alternative embodiments to other embodiments. In light of the disclosure of the embodiments provided by the present invention, it should be understood by those skilled in the art that the embodiments described in the present invention can have other combinations or variations consistent with the concept of the present invention.
The following description of the embodiments refers to the accompanying drawings for illustrating the specific embodiments in which the invention may be practiced. Directional phrases referred to herein, such as [ upper ], [ lower ], [ front ], [ rear ], [ left ], [ right ], [ inner ], [ outer ], [ side ], [ vertical ], [ horizontal ], etc., refer only to the directions of the attached drawings. Accordingly, the directional terms used are used for explanation and understanding of the present invention, and are not used for limiting the present invention.
Fig. 1 is a schematic structural diagram of a transparent liquid crystal display panel 10 according to an embodiment of the present invention. As shown in fig. 1, the transparent liquid crystal display panel 10 mainly includes a lower glass substrate 110, a Polymer Network Liquid Crystal (PNLC) layer 120, an upper glass substrate 130, a quantum dot film layer 140, and a lateral light source 150. The polymer network liquid crystal layer 120 is disposed between the lower glass substrate 110 and the upper glass substrate 130. The lateral light source 150 is disposed on the lower glass substrate 110 at a side of the polymer network liquid crystal layer 120. The quantum dot film layer 140 is disposed on a surface of the glass upper substrate 130 opposite to the polymer network liquid crystal layer 120. The polymer network in the polymer network liquid crystal layer 120 has the same orientation as the liquid crystal molecules, and the ordinary ray refractive index No and the extraordinary ray refractive index Ne of the polymer network are the same as the liquid crystal molecules. Therefore, such a polymer network can be considered as an isotropic substance in all directions. The polymer network liquid crystal layer 120, the lower glass substrate 110 and the upper glass substrate 130 together function as a light guide plate. As shown in fig. 1, the incident angle of the light emitted from the lateral light source 150 is controlled such that the light emitted from the lateral light source 150 is totally reflected in the lower glass substrate 110, the upper glass substrate 130 and the polymer network liquid crystal layer 120 without scattering, and at this time, the display is in a transparent state, so that a user can see the scene behind the display through the display. As shown in fig. 2, when the orientation of the liquid crystal molecules is changed by applying an electric field, due to the mismatch of refractive indexes, the light emitted from the lateral light source 150 is scattered in the light guide plate formed by the lower glass substrate 110, the upper glass substrate 130 and the polymer network liquid crystal layer 120, and the user can see the scattered light, so that the display is in a display state. An extra multi-turn moment is applied to the liquid crystal molecules by utilizing the polymer network, so that the total reaction time (rotation time and reset time) of the liquid crystal molecules in each picture switching process can be shortened, and the picture switching speed of the panel is increased.
Referring to fig. 1, in the embodiment of the invention, the side-in Light source 150 is a blue Light Emitting Diode (LED), and a large-sized display panel is easily implemented because the side-in Light source 150 is a monochromatic Light source without a complicated timing driving circuit. A plurality of pixel control units 202 are disposed on the lower glass substrate 110, and each pixel control unit 202 corresponds to a corresponding color emitting area on the quantum dot film layer 140. The polymer network liquid crystal layer 120 is formed into individual liquid crystal cells 122 at positions corresponding to each pixel control unit 202, so that the polymer network liquid crystal material in each liquid crystal cell 122 can be controlled to twist by the corresponding pixel control unit 202. In order to realize full-color, the quantum dot film layer 140 disposed above the glass upper substrate 130 can convert blue light emitted from the lateral light source 150 into green light and red light. When the blue light emitted by the lateral light source 150 is reflected or refracted to enter the green light conversion region G on the quantum dot film layer 140, the blue light emitted by the lateral light source 150 is converted into green light by the green light conversion region G on the quantum dot film layer 140 and then emitted from the surface of the quantum dot film layer 140, and when the blue light emitted by the lateral light source 150 is reflected or refracted to enter the red light conversion region R on the quantum dot film layer 140, the blue light emitted by the lateral light source 150 is converted into red light by the red light conversion region R on the quantum dot film layer 140 and then emitted from the surface of the quantum dot film layer 140, and the blue light region B on the quantum dot film layer 140 emits the blue light emitted by the lateral light source 150 from the surface of the quantum dot film layer 140. By utilizing the display principle, a polaroid and a color film substrate are not needed, high transparency can be achieved, the advantage of simple driving circuit is achieved, and the large-size display panel can be easily realized.
The polymer network liquid crystal layer 120 injects a liquid crystal material and a polymer monomer into each liquid crystal cell 122 between the lower glass substrate 110 and the upper glass substrate 130 through an One Drop Filling (ODF) process. The upper and lower surfaces of the liquid crystal cell 122 are aligned horizontally or vertically, so that the liquid crystal molecules and the polymer monomers have a uniform orientation. After being photopolymerized by irradiating Ultraviolet (UV), the polymer network liquid crystal layer 120 is formed between the lower glass substrate 110 and the upper glass substrate 130. Since the polymer monomer also has the same anisotropy as the liquid crystal, as shown in fig. 1, in the case where no voltage is applied to the pixel control unit 202 between the lower glass substrate 110 and the upper glass substrate 130, the polymer network liquid crystal layer 120 can be regarded as a transparent and non-scattering optical waveguide. By adjusting the incident angle of the light L emitted from the lateral light source 150, the total reflection of the incident light in the waveguide layer can be realized, so that the display is in a transparent state. As shown in fig. 2, when a voltage is applied to the pixel control unit 202 between the lower glass substrate 110 and the upper glass substrate 130, the polymer network liquid crystal layer 120 has a function of scattering light due to the mismatch between the refractive indexes of the liquid crystal molecules and the polymer, and the display is in a display state of a display screen. By adjusting the driving voltage of the pixel control unit 202 between the lower glass substrate 110 and the upper glass substrate 130, the twist angle of the polymer network liquid crystal in the polymer network liquid crystal layer 120 can be controlled, and the brightness of the emitted light from the quantum dot film layer 140 can be adjusted.
On the surface of the glass upper substrate 130, a quantum dot film layer 140 having various quantum dot regions is prepared through a printing process. As shown in fig. 1, a transparent resin material containing no quantum dots is printed in the blue light region B, materials containing green quantum dots and red quantum dots are printed in the green light conversion region G and the red light conversion region R, respectively, and the scattered blue light is converted into green light and red light and then emitted, so as to realize a full-color display effect. In the present embodiment, the arrangement order of the color light regions is that the three colors, i.e., the blue light region B, the green light conversion region G, and the red light conversion region R, are sequentially arranged from left to right as shown in fig. 1, the color light emitted by adjacent color light regions are different, and the arrangement order of the color light regions can be changed as required in an actual panel product. In addition, the size of each color light region can be adjusted as required by the actual panel product, so that the size of each color light of the blue light region B, the green light conversion region G and the red light conversion region R can be the same or different. The quantum dot film layer material can be indium phosphide (InP), indium selenide (InAs), indium gallium arsenide (InGaAs), indium aluminum arsenide (InAlAs), gallium nitride (GaN), zinc oxide (ZnO), germanium silicide (GeSi), cadmium sulfide (CdS), cadmium selenide (CdSe), cadmium telluride (CdTe) and other materials.
The pixel control unit 202 of the transparent liquid crystal display panel 10 of this embodiment adopts Thin Film Transistors (TFTs) to form a pixel driving circuit array, and the driving chip (not shown) controls the display state of each pixel unit through the driving signals sent by the corresponding gate signal line (not shown) and the corresponding data driving line (not shown). As illustrated in fig. 2, a voltage is applied to the pixel control unit 202 corresponding to the red light conversion region R of the quantum dot film layer 140, so that the polymer network liquid crystal material in the liquid crystal cell 122 corresponding to the red light conversion region R in the polymer network liquid crystal layer 120 is twisted, and the light L emitted from the lateral light source 150 is reflected or scattered to be the light L1, and the light L1 is converted to emit red light through the corresponding red light conversion region R in the polymer network liquid crystal layer 120. As mentioned above, the blue light region B or the green light conversion region R in the polymer network liquid crystal layer 120 also emits blue light or green light in the same manner, which is not described herein again. Therefore, each pixel unit is composed of the corresponding pixel control unit 202, the liquid crystal cell 122 and the color light region on the quantum dot film layer 140.
The transparent liquid crystal display panel of the embodiment of the invention utilizes the polymer network liquid crystal layer to be combined with the quantum dot film layer to control and display the blue light, the green light and the red light of each pixel unit, does not need a polaroid or a color film substrate, can achieve higher transparency, has the advantage of simple driving circuit, and can easily realize a large-size transparent liquid crystal display panel.
In summary, although the present invention has been disclosed with reference to the preferred embodiments, the above-mentioned preferred embodiments are not intended to limit the present invention, and those skilled in the art will appreciate that various modifications and changes can be made without departing from the spirit and scope of the present invention, which is defined by the appended claims.
