Description
Technical Field
The invention relates to a transparent liquid crystal display panel which can simultaneously present the picture of the display panel and the background behind the display panel.
Background
For example, a backlight module is generally disposed on a liquid crystal display panel, and is used for providing backlight to liquid crystal cells, so that corresponding pixel units in the liquid crystal cells transmit light to display images. Since the backlight module is opaque, a viewer cannot see an object or a scene behind the display panel through the display panel screen, and thus the conventional display panel is opaque.
Although the newer oled display panel has a self-luminous property and omits a backlight module, a metal plate for reflecting light is generally provided on the rear surface thereof, and the metal plate is also opaque. Therefore, the viewer also cannot see objects or scenes behind the display panel through the organic light emitting diode display panel.
Therefore, it is necessary to provide a transparent liquid crystal display panel to simultaneously see the display screen and the background behind the display panel to solve the problems of the prior art.

The first polarizing plate 20 has optical transparency and is disposed below the glass substrate 10.
The first transparent electrode plate 30 is disposed above the glass substrate 10, and includes a transparent region 31 and a reflective region 32, wherein the transparent region 31 has light transmittance, and the reflective region 32 has light reflectivity.
The second transparent electrode plate 50 has light transmittance and is disposed opposite to the first transparent electrode plate 30. In addition, the second transparent electrode plate 50 may serve as a common electrode.
The liquid crystal layer 40 is disposed between the first transparent electrode plate 30 and the second transparent electrode plate 50, and includes liquid crystal molecules. In addition, the liquid crystal layer 40 is preferably a liquid crystal layer formed by horizontally arranged liquid crystals, and the liquid crystal layer 40 can be used as a quarter-wave plate.
The color filter substrate 60, which has a light-transmitting property, is disposed on the second transparent electrode plate 50, and includes a colorless portion 61 and a color portion 62, wherein the colorless portion 61 corresponds to the light-transmitting region 31 of the first transparent electrode plate 30, and the color portion 62 corresponds to the reflective region 32 of the first transparent electrode plate 30.
The second polarizing plate 70 is disposed on the color filter substrate 60. In an embodiment of the present invention, an angle between the polarized light absorption axis of the second polarizer 70 and the polarized light absorption axis of the first polarizer 20 is 90 degrees.
The led unit 80 is disposed on the second polarizer 70, and is configured to emit light L2 to the reflective region 32 of the first transparent electrode plate 30, so that the light L2 passes through the liquid crystal layer 40, is reflected by the reflective region 32, passes through the color portion 62 of the color filter substrate 60, and reaches the second polarizer 70, and is configured to present a picture of the transparent liquid crystal display panel. In an embodiment of the invention, the led unit 80 is a red-blue-green field sequential led unit 80 for emitting red light, blue light and green light in a sequential manner, so as to reduce the volume or number of the led units 80, thereby simplifying the structure of the transparent lcd panel.
In addition, the light L1 entering the first polarizing plate 20 from the external environment passes through the first polarizing plate 20, the light-transmitting region 31 of the first transparent electrode plate 30, the liquid crystal layer 40, the second transparent electrode plate 50, the color filter substrate 60, and the second polarizing plate 70 in sequence, and is used for presenting the background behind the transparent liquid crystal display panel.
Referring to fig. 1, when no voltage is applied between the reflective region 32 of the first transparent electrode plate 30 and the second transparent electrode plate 50 during the operation of the transparent liquid crystal display panel, a light L2 emitted by the light emitting diode unit 80 is reflected by the reflective region 32 and then absorbed by the second polarizer 70. Referring to fig. 2, when a voltage is applied between the reflective region 32 of the first transparent electrode plate 30 and the second transparent electrode plate 50 to generate an electric field EF, so as to change the arrangement direction of the liquid crystal molecules of the liquid crystal layer 40, the light L2 emitted by the light emitting diode unit 80 is reflected by the reflective region 32, and passes through the second polarizing plate 70 after the polarization direction of the light is changed by the liquid crystal layer 40.
In an embodiment of the present invention, the voltage applied between the first transparent electrode plate 30 and the second transparent electrode plate 50 is adjusted to change the degree of the light L2 emitted from the light emitting diode unit 80 penetrating through the second polarizer 70, so as to adjust the brightness of the picture of the transparent liquid crystal display panel.

For example, the variable potential difference value may be 0 to 12V. When the applied voltage is larger, the generated electric field EF is stronger, the light L2 of the led unit 80 passes through the second polarizer 70 at a higher rate, the brighter the displayed image is, the weaker the background light L1 is, and the more opaque the transparent lcd panel is.
Compared with the prior art, the first transparent electrode plate 30 is divided into the transparent region 31 and the reflective region 32, and the liquid crystal molecules in the corresponding region of the same liquid crystal layer 40 are aligned by applying a voltage only to the reflective region 32. Therefore, the liquid crystal layer 40 of the invention has a single thickness, and can achieve the display effect of simultaneously displaying the picture of the display panel and the background behind the display panel without setting multiple liquid crystal box thicknesses, thereby realizing the transparent liquid crystal display panel. In addition, the present invention can determine the degree of the light L2 emitted from the led unit 80 passing through the second polarizer 70 by changing the intensity of the applied voltage, so as to change the transparency of the transparent lcd panel, and allow the user to adjust the most suitable picture transparency.
