The electronic device provided by the embodiment of the present application is described in detail with reference to fig. 1 to 9 through specific embodiments and application scenarios thereof.

As shown in fig. 1 to 3, an embodiment of the present application provides an electronic device, including: a backplane 1 and a processor 3; the back plate 1 has a first functional area 101; the first functional area 101 includes a display 11 and a substrate layer 12.

The bottom lining layer 12 is arranged on the back surface of the display screen 11, and one side surface, facing the display screen 11, of the bottom lining layer 12 is provided with a background feature 121; the processor 3 is connected with the display screen 11 to control the display screen 11 to be in a screen-off state or a display state.

Under the condition that the display screen 11 is in the screen-off state, the display screen 11 is transparent, so that the background feature 121 can be displayed through the display screen 11; in a case where the display screen 11 is in a display state, the display screen 11 may display the target information under the control of the processor 3.

It will be appreciated that the substrate layer 12 includes a transparent substrate and background features 121, the background features 121 are disposed on a side of the transparent substrate facing the display screen 11, and the background features 121 include a planar pattern and a three-dimensional pattern. For example, the planar pattern may include at least one background color, or different types of background pictures such as a landscape, a character image, a LOGO (LOGO), an Identification (ID), etc.; the solid pattern may be a contoured pattern structure or a relief-type structure. In practical applications, the background features 121 can be designed in various styles and in a customized manner according to the display requirements of the user for the background features 121 on the backplate 1.

Meanwhile, the display screen 11 according to the embodiment of the present application may be a liquid crystal display screen known in the art, and the display screen 11 may be made of a transparent material. When the display screen 11 is powered off and in a rest state when the processor 3 does not perform display control on the display screen 11, the background features 121 on the bottom lining 12 can be displayed through the display screen 11. Wherein, under the condition that the display screen 11 is in the screen-off state, the transmittance of the display screen 11 to the light is more than 85%.

Accordingly, when the processor 3 applies a driving voltage to the light source and the driving circuit on the display screen 11, the display screen 11 is in a display state, the display screen 11 can display target information under the control of the processor 3, and application of a multifunctional interaction scene requirement can be achieved, for example, the display screen 11 can perform shooting preview and display target information such as time and social information under the control of the processor 3.

So, based on above-mentioned design, the display function of backplate 1 of this application is not subject to the influence of display screen 11 operating condition, has realized that backplate 1 shows the diversification of function, helps promoting backplate 1's outward appearance appeal.

It should be noted here that, in the embodiment of the present application, the electronic device may be a mobile terminal, for example: smart phones, tablet Personal computers (Tablet Personal computers), laptop computers (Laptop computers), personal Digital Assistants (PDAs), mobile Internet Devices (MIDs), wearable devices (Wearable devices), and the like, and may also be other electronic devices such as digital cameras, electronic books, navigators, and the like.

In some embodiments, as shown in fig. 3 and 4, the display panel 11 of the embodiments of the present application includes a light source assembly 111, a first substrate 112, a liquid crystal layer 113, and a second substrate 114, where both the first substrate 112 and the second substrate 114 are transparent substrates.

The liquid crystal layer 113 is sandwiched between the first substrate 112 and the second substrate 114, an electrode layer 1122 is disposed on one side of the first substrate 112 facing the liquid crystal layer 113, and a driving circuit is disposed on one side of the second substrate 114 facing the liquid crystal layer 113; the light source assembly 111 is disposed at one side of the liquid crystal layer 113; the light source assembly 111, the electrode layer 1122 and the driving circuit are electrically connected to the processor 3, respectively.

The light emitted from the light source assembly 111 is irradiated into the liquid crystal layer 113, and can be output from the side of the first substrate 112 away from the second substrate 114 under the control of the liquid crystal layer 113.

It is understood that the first substrate 112 includes a first transparent base layer 1121 and an electrode layer 1122, and the electrode layer 1122 is disposed on a side of the first transparent base layer 1121 facing the liquid crystal layer 113. The second substrate 114 includes a second transparent base layer 1141 and a driving circuit disposed on a side of the second transparent base layer 1141 facing the liquid crystal layer 113.

In order to ensure that the display screen 11 is transparent under the screen shape, the first transparent base layer 1121 and the electrode layer 1122 on the first substrate 112 are made of transparent materials, and the second transparent base layer 1141 and the driving circuit on the second substrate 114 are made of transparent materials. The first transparent substrate layer 1121 and the second transparent substrate layer 1141 may both be transparent glass substrates, the electrode layer 1122 may be made of transparent Indium Tin Oxide (ITO), and the driving circuit may be a Thin Film Transistor (TFT) driving circuit.

Meanwhile, the light source assembly 111 includes a red light source 1111, a green light source 1112, and a blue light source 1113. The light source assembly 111 may specifically select a red LED lamp, a green LED lamp, and a blue LED lamp. In practical applications, the processor 3 can respectively perform time-sharing control on the red light source 1111, the green light source 1112, and the blue light source 1113, so as to realize color control of the light transmitted from the light source assembly 111 to the liquid crystal layer 113.

In this way, since the electrode layer 1122 and the driving circuit are connected to the processor 3, the processor 3 can control the optical transmittance of each liquid crystal cell 1131 corresponding to the liquid crystal layer 113 through the driving circuit, thereby controlling the display panel 11 to perform pixel display of a picture actually required.

Compared with the prior art, the display structure can be simplified based on the light entering from the side of the light source assembly 111 to the liquid crystal layer 113, and not only the Black Matrix (BM) and the Color Film (CF) do not need to be arranged on the first substrate 112, but also the polarizer is not required to be arranged on the side of the first substrate 112 deviating from the liquid crystal layer 113, and the lower polarizer is not required to be arranged on the side of the second substrate 114 deviating from the liquid crystal layer 113.

In some embodiments, as shown in fig. 4, to facilitate display control of the display panel 11, the liquid crystal layer 113 of the embodiment of the present application includes a plurality of liquid crystal cells 1131; the driving circuit includes a plurality of TFT driving units 1142, and the plurality of TFT driving units 1142 may be disposed in an array on the second substrate 114.

The electrode layer 1122 is connected with a plurality of liquid crystal cells 1131, and the plurality of liquid crystal cells 1131 are connected with a plurality of TFT driving units 1142 in a one-to-one correspondence manner; the electrode layer 1122 and the plurality of TFT driving units 1142 are connected to the processor 3, respectively.

The Liquid Crystal cell 1131 may adopt Polymer Dispersed Liquid Crystal (PDLC) or Polymer Network Liquid Crystal (PNLC).

Thus, in practical applications, a part of the TFT driving units 1142 can be controlled by the processor 3 to operate according to display requirements of actual pictures, so as to control the light transmittance of the liquid crystal cells 1131 corresponding to the TFT driving units 1142, and light incident from the light source assembly 111 can be output from one side of the first substrate 112 away from the second substrate 114 under the control of the liquid crystal cells 1131.

Next, the display control of the target information by the display screen 11 will be described in detail below with reference to fig. 5.

When the display screen 11 is in the screen-off state, each TFT driving unit 1142 does not operate, and the processor 3 does not perform light-emitting control on the light source assembly 111, so that the overall structure of the display screen 11 maintains a high transmittance, and the background features 121 can be displayed on the display screen 11.

When the display screen 11 is in a display state, the processor 3 performs line-by-line scanning pixel level control on the plurality of TFT driving units 1142 arranged in an array, and performs time-sharing control on the red LED lamp, the green LED lamp, and the blue LED lamp corresponding to the light source component 111, so that the light source component 111 provides red light, green light, and blue light in a time-sharing manner, so as to implement an R/G/B color display function of the display screen 11 by matching with the pixel control.

For example, when the display screen 11 is controlled to display a "VIVO" icon, at a first time, the red LED lamp is controlled to be turned on, and simultaneously the associated pixel is turned on, so as to control the display of the R pixel of the demand picture, so that the first position and the fourth position of the display screen 11 respectively display red "V" and "O"; at the second moment, the green LED lamp is controlled to be turned on, the associated pixel is turned on, and the display of the pixel G of the demand picture is controlled, so that the green I and the green O are respectively displayed at the second position and the fourth position of the display screen 11; at the third moment, the blue LED lamp is controlled to be turned on, the associated pixel is turned on, and the display of the B pixel of the demand picture is controlled, so that the third position and the fourth position of the display screen 11 respectively display blue V and O; the above-mentioned steps are repeated according to the time sequence, so that the display screen 11 can display the colored "VIVO" icon.

In some embodiments, as shown in fig. 6, the electrode layer 1122 of embodiments of the present application includes a plurality of touch electrode blocks 11221; the plurality of touch electrode blocks 11221 are separated from each other and arranged in an array to form self-contained touch electrodes.

It can be understood that the self-capacitance type touch electrode utilizes the capacitance change of the single touch electrode block 11221 to transmit electric charges, one end of each touch electrode block 11221 is grounded, and the other end of each touch electrode block 11221 is connected to the processor 3 with the excitation or sampling circuit through a conductive wire, so that the capacitance of each touch electrode block 11221 can be identified through the processor 3.

When a finger touches the display screen 11, the capacitance of the finger is superposed on the touch electrode block 11221, so that the capacitance of the touch electrode block 11221 to the ground is changed, and the touch identification of the finger is realized.

Because the plurality of touch electrode blocks 11221 in the self-capacitance touch electrode can form a transverse electrode array and a longitudinal electrode array, when touch detection is performed through the self-capacitance touch electrode, the capacitances of the transverse electrode array and the longitudinal electrode array are respectively detected, transverse coordinates and longitudinal coordinates are respectively determined according to the change of the capacitances before and after touch, and then the transverse coordinates and the longitudinal coordinates are combined into planar touch coordinates. Here, the scanning method for the self-contained touch electrode is equivalent to projecting the touch points on the display screen 11 to the X-axis direction and the Y-axis direction, calculating the coordinates in the X-axis direction and the Y-axis direction, and finally combining the coordinates to the coordinates of the touch points.

In some embodiments, as shown in fig. 4, the liquid crystal layer 113 of the embodiments of the present application further includes a plurality of supporters 1132; a plurality of supporters 1132 are supported between the first substrate 112 and the second substrate 114, and each liquid crystal cell 1131 is disposed between two adjacent supporters 1132.

Specifically, the present embodiment can prevent the liquid crystal cell 1131 from being squeezed by providing the support member 1132 in the liquid crystal layer 113. Meanwhile, the plurality of supporting members 1132 may form a supporting member array, and the supporting member array may deform according to a pressure value of the pressure touch signal when receiving the pressure touch signal, and a predetermined corresponding relationship exists between a deformation amount of the deformation and the magnitude of the pressure value.

The supporting member 1132 may be made of an elastic material such as rubber or resin. Optionally, the supporting member 1132 is a Photo Spacer (PS) which is a transparent column to facilitate transmission of light generated by the light source assembly 111 in the liquid crystal layer 113.

In some embodiments, as shown in fig. 3, the backsheet 1 of the present embodiment further includes a transparent protective layer 13; the transparent protective layer 13 is disposed on a side of the first substrate 112 facing away from the liquid crystal layer 113.

The transparent protection layer 13 may be made of a transparent material and has a high transmittance to light, and the transparent protection layer 13 and a side of the first substrate 112 away from the liquid crystal layer 113 may be bonded together by a conventional bonding process to protect the display 11 based on the transparent protection layer 13.

Of course, in practical applications, the display panel 11 of the embodiment can also emit light through the second substrate 114, and the transparent protection layer 13 can be disposed on a side of the second substrate 114 away from the liquid crystal layer 113.

Further, in order to facilitate the layout of the light source assemblies 111, the length of the liquid crystal layer 113 and the length of the first substrate 112 are both smaller than the length of the second substrate 114 along the first direction in the present embodiment; the light source assembly 111 is disposed on the same side of the first substrate 112 and the liquid crystal layer 113, and is sandwiched between the transparent protection layer 13 and the second substrate 114.

In this embodiment, the lengths of the first substrate 112 and the liquid crystal layer 113 along the first direction may be set to be the same, and when the first side of the first substrate 112, the first side of the liquid crystal layer 113, and the first side of the second substrate 114 are aligned, the second side of the first substrate 112 and the second side of the liquid crystal layer 113 are aligned, and a gap space is formed between the first side of the first substrate 112 and the second side of the second substrate 114, so that the light source assembly 111 can be disposed in the gap space.

Because display screen 11 is transparent under the breath screen state, based on the high transmissivity (the transmissivity is greater than 85%) of display screen 11 to light, can satisfy the shooting function of module 2 to the target object of making a video recording to can form the protection to module 2 based on display screen 11 and transparent protective layer 13 of making a video recording. Meanwhile, when the display screen 11 is in a display state, the experience effect of hiding the camera module 2 can be obtained based on the color change of the display screen 11.
