Referring to fig. 6 and 7, fig. 6 is a fourth structural schematic diagram of an electronic device according to an embodiment of the present application, and fig. 7 is a sectional structural schematic diagram of the electronic device taken along a line P3-P3 in fig. 6. The display layer 22 of the first display panel 20 may include a first polarizing layer 223a, a driving circuit layer 224a, a liquid crystal layer 225a, a color filter layer 226a, and a second polarizing layer 227a, which are sequentially stacked.

The first polarizing layer 223a, the driving circuit layer 224a, the liquid crystal layer 225a, the color filter layer 226a, and the second polarizing layer 227a may be located in the second part 222. The backlight layer 24 may be disposed below the first polarizing layer 223a, that is, the backlight layer 24 is disposed on a side of the first polarizing layer 223a away from the driving circuit layer 224 a.

The liquid crystal layer 225a may include a plurality of liquid crystal droplets disposed in small cells of the liquid crystal layer 225a, one cell forming one pixel unit on the first display screen 20. The liquid crystal layer 225a may also have electrodes and traces, where the electrodes cause the liquid crystal to twist differently under different voltages, thereby changing the angle of the light.

The driving circuit layer 224a may have a plurality of driving units disposed therein, and the plurality of driving units may be disposed in the second portion 222 of the display layer 22, and the driving units are electrically connected to the liquid crystal to drive the liquid crystal to rotate. Specifically, the driving unit may include a thin film transistor, and the driving unit may control a voltage applied to the liquid crystal, a magnitude, a duration, and the like of the voltage, so that the liquid crystal is deflected by different angles.

A first linear polarizer may be disposed in the first polarizing layer 223a, and a second linear polarizer may be disposed in the second polarizing layer 227 a. That is, the first and second linear polarizers are located at opposite sides of the liquid crystal, and the first and second linear polarizers may be located in the second portion 222 of the display layer 22.

Wherein the first linear polarizer may cause the natural light provided by the backlight layer 24 to become linear light and then pass through the first linear polarizer. Since a certain angle is formed between the first linear polarizer and the second linear polarizer, the linear light passing through the first linear polarizer is not always transmitted through the second linear polarizer, so that the first display 20 is represented as a black screen. When a voltage is applied to the liquid crystal of the liquid crystal layer 225a, the liquid crystal rotates, so that the line light penetrating through the first linear polarizer continuously deflects for a certain angle, and when the rotating angle of the liquid crystal is consistent with the angle between the first linear polarizer and the second linear polarizer, the line light can pass through the second linear polarizer after the liquid crystal deflects, so that the line light is perceived by eyes of a user, and the first display screen 20 can display information.

The driving unit may control a voltage applied to the liquid crystal to control the liquid crystal to deflect at different angles, so that the amount of light passing through the second linear polarizer is different, thereby generating different brightness for the first display 20.

The color filter layer 226a may include a glass substrate, a black matrix, a color filter, and the like. The black matrix can be arranged relative to the driving unit to shield the driving unit and reduce the influence of the driving unit on light. The color filter may filter the white light emitted from the light source of the backlight layer 24 into color light of different colors, and the color light may be transmitted to the outside of the display layer 22 to enable the first display 20 to display colors.

Here, a black matrix and a color filter may be disposed on a side of the liquid crystal layer 225a away from the backlight layer 24, and the black matrix and the color filter may be disposed between the liquid crystal and the second linear polarizer 227.

It is understood that the backlight layer 24 may be packaged as a whole with the first polarizing layer 223a, the driving circuit layer 224a, the liquid crystal layer 225a, the color filter layer 226a and the second polarizing layer 227a located above the backlight layer, so that light emitted from the backlight layer 224 does not leak into the electronic device 100, which may affect the display effect of the first display 20.

The principle of the first display screen 20 displaying information in the embodiment of the present application is as follows: light emitted by the light source of the backlight layer 24 enters the liquid crystal layer 225a formed by liquid crystal droplets after being filtered by the first polarizing layer 224a, the liquid droplets of the liquid crystal layer 225a are all in small cells, and one cell forms one pixel point on a picture. The electrodes in the liquid crystal layer 225a allow the liquid crystal to be twisted differently under different voltages, so that the angle of the light is changed, the light continues to pass through the color filter layer 226 after being twisted, and the light passes through the second polarizing layer 227a to be transmitted out of the first display screen 20, so as to be received by the eyes of the user.

Under different voltages, the liquid crystal molecules are twisted and changed to different degrees, and further, the light passes through the liquid crystal molecules to be twisted and changed to different degrees. The liquid crystal display device changes the arrangement condition of liquid crystal molecules in the liquid crystal layer through voltage so as to achieve the purposes of shading and transmitting light and display images with different depths and uniform alignment. By providing the color filter layer 226a between the liquid crystal layer 225a and the second polarizing layer 227a, a color image can be realized.

The second display screen 40 of the embodiment of the present application may be an LED display screen, and the LED display screen may include a light emitting diode matrix panel and a control circuit. The LED matrix panel can be arranged with a plurality of LEDs, the control circuit can control whether the LEDs emit light, brightness, color, etc., so that different LEDs on the LED matrix panel emit light with different colors and different brightness, and users can feel the information displayed by the LED display screen after receiving the light.

It can be understood that the second display screen 40 can control the light emitting diode matrix panel to emit light, that is, when the second display screen 40 displays information, it is not necessary to control the liquid crystal to deflect and to set two polarizers at the upper and lower sides of the liquid crystal to control the light transmission and light shielding.

Based on this, the first portion 221 of the display layer 22 located above the second display screen 40 may include a first polarizing layer 223b, a driving circuit layer 224b, a liquid crystal layer 225b, a color filter layer 226b, and a second polarizing layer 227b, which are sequentially stacked. The first polarizing layer 223b, the driving circuit layer 224b, the liquid crystal layer 225b, the color filter layer 226b, and the second polarizing layer 227b are located in the first part 221. The second display screen 240 is disposed at a side of the first polarizing layer 223b away from the driving circuit layer 224b, that is, the second display screen 240 is disposed below the first polarizing layer 223 b.

The liquid crystal layer 225b may include a plurality of liquid crystal droplets, each of which is in a small cell of the liquid crystal layer, one cell forming one pixel unit on the first display screen 20. The liquid crystal layer 225b may also have electrodes and traces, where the electrodes cause the liquid crystal to twist differently under different voltages, thereby changing the angle of the light.

It is understood that the liquid crystal layer 225a and the liquid crystal layer 225b may be one integral body. A single glass substrate may be disposed above the liquid crystal layer 225a and the liquid crystal layer 225b to cover both the liquid crystal layer 225a and the liquid crystal layer 225b, and a single glass substrate may be disposed below the liquid crystal layer 225a and the liquid crystal layer 225b to support both the liquid crystal layer 225a and the liquid crystal layer 225 b.

The liquid crystal droplets located in the second portion 222 and the liquid crystal droplets located in the first portion 221 are disposed between two glass substrates, and the liquid crystal droplets can freely flow under the action of a voltage. No frame is required to be arranged between the liquid crystal layer 225a and the liquid crystal layer 225b to prevent the liquid crystal located in the second portion 222 from flowing into the first portion 221, no frame exists between the second portion 222 and the first portion 221, and the first display screen 20 does not cause a black frame which cannot be displayed to exist between the second portion 222 and the first portion 221 when displaying a picture.

In the embodiment of the present application, the first portion 221 and the second portion 222 of the display layer 22 are both provided with liquid crystal, and further, when a user views from the outside of the first display screen 20 through the second portion 222 and the first portion 221, the user can see information displayed on the first display screen 20 through the second portion 222, and the user can see information displayed on the second display screen 40 through the first portion 221, so that the first display screen 20 and the second display screen 40 display more naturally.

Because the display information of the LED display screen does not depend on the deflection of the liquid crystal, the driving circuit layer 224b may not be disposed in the first portion 221, and a corresponding region of the driving circuit layer 224b of the first portion 221 may be a hollow structure to increase the light transmittance of the first portion 221.

It is understood that the driving circuit layer 224a and the driving circuit layer 224b may be a whole, that is, a whole glass substrate may be disposed above the driving circuit layer 224a and the driving circuit layer 224b to cover the driving circuit layer 224a and the driving circuit layer 224b, and a whole glass substrate may be disposed below the driving circuit layer 224a and the driving circuit layer 224b to jointly carry the driving circuit layer 224a and the driving circuit layer 224 b.

It is understood that the metal traces can be replaced with tin oxide material to further increase the light transmittance of the first portion 221.

Since the display information of the LED display screen does not depend on the deflection of the liquid crystal, the corresponding region of the first polarizing layer 223b of the first portion 221 may be a hollow structure to increase the light transmittance of the first portion 221.

It is understood that the first polarizing layer 223b may not have polarizing properties. That is, the optical film having polarization may not be disposed in the first polarizing layer 223b, so as to prevent the optical film from blocking the transmission of light, and reduce the light transmittance of the first portion 221.

Wherein, the first polarizing layer 223a and the first polarizing layer 223b may be a whole, a whole piece of glass sheet may be disposed above the first polarizing layer 223a and the first polarizing layer 223b to cover the first polarizing layer 223a and the first polarizing layer 223b at the same time, and a whole piece of glass sheet may be disposed below the first polarizing layer 223a and the first polarizing layer 223b to jointly bear the first polarizing layer 223a and the first polarizing layer 223 b.

In the embodiment of the present application, the first polarizing layer 223a and the first polarizing layer 223b are integrated, so that the layered structure of the display layer 22 can be more stable.

Since the light emitting diodes of the LED display screen can emit light sources with different colors, the first portion 221 may not have the color filter layer 226b, and a corresponding area of the color filter layer 226b of the first portion 221 may be a hollow structure to increase the light transmittance of the first portion 221.

It is understood that the color filter layer 226a and the color filter layer 226b may be an integral body, a whole glass sheet may be disposed above the color filter layer 226a and the color filter layer 226b to cover the color filter layer 226a and the color filter layer 226b at the same time, and a whole glass sheet may be disposed below the color filter layer 226a and the color filter layer 226b to support the color filter layer 226a and the color filter layer 226b together.

A color filter and a black matrix may be disposed between the two glass sheets and opposite to the second portion 222, the black matrix is opposite to the driving unit to shield the driving unit, and light emitted from the backlight layer 24 is transmitted to the outside of the display layer 22 through the color filter. The position between the two glass substrates corresponding to the first portion 221 may not be provided with a color filter and a black matrix, so as to reduce the light shielding of the color filter and the black matrix. In the embodiment of the present application, the color filter layer 226a and the color filter layer 226b are integrated, so that the layered structure of the display layer 22 can be more stable.

A circular polarizer may be disposed in the second polarizing layer 227 b. That is, the circular polarizer is located in the first portion 221 of the liquid crystal layer 225b on the side away from the backlight layer 24. Half of the light can not pass through when the external light enters the circular polarizer, the light passing through the circular polarizer meets other metal wires in the display layer 22, the angle between the light reflected by the electrode and the light entering originally is deflected by 90 degrees, so that the reflected light can not enter the eyes of the external user through the circular polarizer again, the effect of the reflected light on the display effect can be reduced, and the display effect of the second display screen 40 is improved.

Moreover, when the first polarizing layer 223a and the second polarizing layer 227a of the second portion 222 are provided with the wired polarizers, when the first display screen 0 displays information, the first polarizing layer 223a and the second polarizing layer 227a cooperate with each other to reduce the influence of the reflected light on the display effect of the second portion 222. Therefore, the circular polarizer is disposed in the second polarizing layer 227b of the first portion 221, and the circular polarizer can also reduce the influence of the reflected light on the first portion 221, so that the second portion 222 and the first portion 221 do not have a noticeable boundary sense when the first display panel 20 and the second display panel 40 display information, and the second portion 222 and the first portion 221 transition more naturally.
