Detailed Description
Features and exemplary embodiments of various aspects of the present application will be described in detail below. In the following detailed description, numerous specific details are set forth in order to provide a thorough understanding of the present application. It will be apparent, however, to one skilled in the art that the present application may be practiced without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the present application by illustrating examples thereof.
It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The embodiments will be described in detail below with reference to the accompanying drawings.
In one aspect, the present application provides a display panel. For a better understanding of the technical solutions and effects of the present application, specific embodiments will be described in detail below with reference to the accompanying drawings.
Referring to fig. 1 and 2, the display panel 100 includes a non-display area NA and a display area DA, the display area DA is at least partially disposed around the non-display area NA, and the light transmittance of the non-display area NA is greater than that of the display area DA. The display area DA is an area of the display panel 100 where an image is displayed, and the display area DA is provided with a plurality of pixel units for displaying, and the non-display area NA is not provided with pixel units, so that the pixel units are prevented from reducing the light transmittance of the non-display area NA. The non-display area NA has a large light transmittance, so that the photosensitive module is suitable to be arranged, and external light can enter the photosensitive module through the non-display area NA to realize framing and shooting. The display area DA of the embodiment of the application may implement image display based on a Liquid Crystal Light Emitting component (Liquid Crystal), an Organic Light Emitting Diode (OLED for short), a Micro Light Emitting Diode (Micro-LED for short), or a Quantum dot Light Emitting Diode (QLED for short).
Referring to fig. 3, the display panel 100 includes a first substrate 10, a second substrate 20, a liquid crystal layer 30 and a first driving electrode 1; the liquid crystal layer 30 is arranged between the first substrate 10 and the second substrate 20, and medium liquid crystal is arranged in the liquid crystal layer 30; the first driving electrode 1 is located in the non-display area NA, the first driving electrode 1 is used for driving the liquid crystal located in the non-display area NA to deflect, the display panel 100 has a peep-proof state and an imaging state, and the light transmittance of the non-display area NA in the peep-proof state is smaller than that of the non-display area NA in the imaging state.
The peep-proof state of the display panel 100 corresponds to a situation that the user does not need to use the photosensitive module 200, and may be a standby state of the display panel 100, or a state in which the photosensitive module 200 does not work at a stage when the display area DA displays an image. First drive electrode 1 can deflect through applying different voltage drive liquid crystal, utilizes the light transmittance of the optical rotation regulation non-display area NA of liquid crystal, compares with the formation of image state, and the light transmittance of non-display area NA under the peep-proof state is less, and the luminous flux that sensitization module 200 received is not enough to form clear formation of image, even if the illegal work of calling sensitization module 200 of external equipment, also can't form an image to avoid user's privacy to reveal. The imaging state of the display panel 100 corresponds to the condition that the user needs to use the photosensitive module 200, and compared with the peeping prevention state, the light transmittance of the non-display area NA in the imaging state is large, and the luminous flux received by the photosensitive module 200 can form clear imaging. A second driving electrode 2 may also be disposed in the display area DA, and the second driving electrode 2 is used for driving the pixel units in the display area DA to display images. The first driving electrode 1 and the second driving electrode 2 may be separately controlled so that the light transmittance of the non-display area NA and the image display in the display area DA may be independently controlled.
In the display panel 100 provided in the embodiment of the application, by setting the light transmittance of the non-display area NA to be greater than that of the display area DA, the photosensitive module 200 is more suitable to be disposed on one side of the non-display area NA compared with the display area DA, which is beneficial to improving the imaging effect of the photosensitive module; meanwhile, the first driving electrode 1 is arranged in the non-display area NA, the first driving electrode 1 is arranged to drive the liquid crystal in the non-display area NA to deflect, the different light transmittance of the non-display area NA in the peeping-proof state and the imaging state is correspondingly adjusted by utilizing the optical rotation of the liquid crystal, and the light flux entering the photosensitive module 200 is further controlled, so that the high light flux in the imaging state can be met, and the imaging effect is improved; and the luminous flux at the position can be reduced in the peep-proof mode, the existence of the photosensitive module 200 is hidden visually, the integrity of the display state can be improved, the imaging of the photosensitive module 200 can be controlled by avoiding illegal calling of external equipment, and the privacy of users can be protected.
Referring to fig. 4, in some embodiments, the first driving electrode 1 includes a first electrode 11 and a second electrode 12, the second electrode 12 includes a plurality of sub-electrodes 121 disposed opposite to the first electrode 11, and an electric field for controlling liquid crystal deflection is generated between the first electrode 11 and the sub-electrodes 121. The electric field for controlling the deflection of the liquid crystal can be formed by applying voltages to the first electrode 11 and the second electrode 12, respectively.
The number of the sub-electrodes 121 may be set to be any number according to the requirement, which is not particularly limited in the present invention. The sub-electrodes 121 may be equally spaced apart from each other, and the sub-electrodes 121 may be identical in size and shape. The shape of the sub-electrode 121 is not limited in this application, and may be an ellipse, a circle, a circular ring, or the like. In order to ensure that the display area DA in the display panel 100 has a larger area and the photosensitive module 200 has a proper light flux in the imaging mode, the size and shape of the non-display area NA may be set according to the size and shape of the viewing opening of the photosensitive module 200, and the plurality of sub-electrodes 121 may be regularly laid in the non-display area NA, so that an electric field for controlling the liquid crystal deflection may be formed everywhere in the non-display area NA.
In order to ensure that the non-display area NA has a large light transmittance, the first electrode 11 and the second electrode 12 are both transparent electrodes. The transparent electrode may be an ITO (indium tin oxide) electrode or an electrode made of other transparent materials. In an embodiment, the first substrate 10 may be an array substrate, and the second substrate 20 may be a color filter substrate. In order to further improve the light transmittance of the non-display area NA, the array substrate and the color filter substrate located in the non-display area NA may only have the transparent material layer, for example, the array substrate includes the transparent material layers such as the glass substrate on the array substrate side, the buffer layer, and the alignment layer, and the color filter substrate includes the alignment layer on the color filter substrate side, the optical adhesive layer, and the glass substrate.
In an embodiment, each sub-electrode 121 is connected to a different signal line, so as to apply a corresponding driving signal to the different sub-electrodes 121 through the different signal lines, and control the potential of each sub-electrode 121, so that the sub-electrodes 121 and the first electrode 11 form a non-uniform electric field distribution, and any liquid crystal in the non-display area NA can be controlled to deflect to any position, so that different positions in the non-display area NA have different light transmittance. In another embodiment, the plurality of sub-electrodes 121 are connected to each other, and the potentials of the connected sub-electrodes 121 are the same in at least one of the peep prevention state and the imaging state. The plurality of connected sub-electrodes 121 may share only one input terminal to be connected to an external circuit, and the external circuit inputs a driving signal through the input terminal to control the deflection of the liquid crystal located in the non-display area NA. The wiring scheme of the plurality of connected sub-electrodes 121 with the same potential can reduce the wiring complexity of the first driving electrode 1 and improve the light transmittance of the non-display area NA in the imaging state.
Because in the imaging state, external light needs to pass through the sub-electrodes 121 and pass through the gaps between the adjacent sub-electrodes 121, the light can be scattered and transmitted in different degrees when passing through the slits between the adjacent sub-electrodes 121, so that diffraction phenomenon is generated during imaging, and the imaging effect of the photosensitive module 200 is affected. At least a portion of the outer edges of the sub-electrodes 121 are arranged in a curved line to change the width of the slits between the adjacent sub-electrodes 121, reducing the diffraction phenomenon.
Optionally, referring to fig. 5, at least two sub-electrodes 121 are annular and are sleeved with each other. The sub-electrodes 121 nested one another may be coaxially disposed, and the annular slit formed between the adjacent sub-electrodes 121 exposes the first electrode 11.
Optionally, referring to fig. 6, the second electrode 12 further includes a sub-electrode extension portion 122, and the sub-electrode extension portion 122 is connected to the plurality of annularly sleeved sub-electrodes 121. The sub-electrode extension 122 has conductivity such that the plurality of sub-electrodes 121 connected through the sub-electrode extension 122 can achieve the same potential. The wiring complexity of the first driving electrode 1 can be reduced by connecting the plurality of sub-electrodes 121 through the sub-electrode extension portions 122; similarly, the sub-electrode extension 122 may also be configured as a transparent electrode to improve the light transmittance of the non-display area NA in the imaging state.
Alternatively, referring to fig. 7, the shape of the sub-electrode extension 122 is not limited in the present application, and the sub-electrode extension 122 may also be a circular electrode located at the center of the plurality of annular sub-electrodes 121, and a strip shape connected to the central circular electrode.
Referring to fig. 8, in another embodiment, the sub-electrodes 121 are circular, and the sub-electrodes 121 are arranged in an array at intervals. Likewise, a person skilled in the art may arrange the plurality of circular sub-electrodes 121 according to the shape of the non-display area NA, such that the sub-electrodes 121 are uniformly arranged within the non-display area NA. The sub-electrodes 121 and the first electrode 11 spaced in an array form a uniform electric field distribution.
At least two adjacent sub-electrodes 121 are electrically connected to each other through a metal trace 123, and the metal trace 123 extends in a curved shape. Compared with the metal trace 123 with a straight extension form, the curved metal trace 123 can reduce the diffraction phenomenon.
Referring to fig. 9, the first substrate 10 further includes a second driving electrode 2 located in the display area DA, the second driving electrode 2 includes a pixel electrode 21 and a common electrode 22, and the first electrode 11 and the common electrode 22 are insulated from each other, or the first electrode 11 and the common electrode 22 are communicated with each other to form a whole electrode.
The first electrode 11 may be disposed on the same layer as the pixel electrode 21 or the common electrode 22, and the second electrode 12 may be disposed on the same layer as the pixel electrode 21 or the common electrode 22, so as to reduce the number of manufacturing steps and reduce the overall thickness of the display panel 100. For example, when the display area DA is used for implementing image display based on ffs (fringe Field switching) technology, the first electrode 11 and the common electrode 22 may be disposed in the same layer, and the second electrode 12 and the pixel electrode 21 may be disposed in the same layer. Referring to fig. 10, when the display area DA is based on ips (in Plane switching) technology, either the first electrode 11 or the second electrode 12 may be formed in the same layer as the common electrode 22 and the pixel electrode 21.
Since the light inlet of the photosensitive module 200 is mostly circular, the first electrode 11 can be a circular electrode.
Referring to fig. 11, the display panel 100 further includes a first polarizer 40 and a second polarizer 50, wherein the first polarizer 40 is disposed on a side of the second substrate 20 away from the liquid crystal layer 30; the second polarizer 50 is disposed on a side of the first substrate 10 away from the liquid crystal layer 30; the first polarizer 40 and/or the second polarizer 50 includes a secondary polarizing portion 401 and a main polarizing portion 402, the secondary polarizing portion 401 is located in the non-display area NA, the main polarizing portion 402 is at least partially located in the display area DA, and the light transmittance of the secondary polarizing portion 401 is greater than that of the main polarizing portion 402.
Only the light with the polarization direction matched with the first polarizer 40 can penetrate through the first polarizer 40, and only the light with the polarization direction matched with the second polarizer 50 can penetrate through the second polarizer 50, so that the polarization direction of the light can be adjusted by the liquid crystals with different deflection angles. Therefore, in the image forming state, the light having the polarization direction matched with the first polarizer 40 among the external light passes through the first polarizer 40, and a large amount of light having the polarization direction matched with the second polarizer 50 may be emitted from the second polarizer 50. In the privacy state, light having a polarization direction matched with that of the first polarizer 40 among external light passes through the first polarizer 40, and no or a small amount of light having a polarization direction matched with that of the second polarizer 50 may be emitted from the second polarizer 50.
In the display panel 100, the first polarizer 40 may be provided with a main polarizing portion 402 and a sub-polarizing portion 401 having different light transmittances, the second polarizer 50 may be provided with a main polarizing portion 402 and a sub-polarizing portion 401 having different light transmittances, or both the first polarizer 40 and the second polarizer 50 may be provided with a main polarizing portion 402 and a sub-polarizing portion 401 having different light transmittances. By providing the main polarizing portion 402 and the sub polarizing portion 401 having different light transmittances and providing the sub polarizing portion 401 having a higher light transmittance in the non-display area NA, the light transmittance of the non-display area NA in an image forming state can be improved.
The polarization directions of the light rays which can penetrate through the secondary polarization part 401 of the first polarizer 40 and the secondary polarization part 401 of the second polarizer 50 can be arranged in an intersecting manner; in an imaging state, the first driving electrode 1 drives the liquid crystal in the non-display area NA to deflect, so that the polarization direction of the incident light passing through the first polarizer 40 may be changed and the incident light may pass through the second polarizer 50.
When the display panel 100 is in a standby state, that is, when a user does not need to use the display panel 100 to display a picture, the external circuit may not send a driving signal to the first driving electrode 1, so that liquid crystal in the liquid crystal layer 30 may present any deflection angle, so that light incident on the second polarizer 50 has different polarization directions, and light incident from the second polarizer 50 is insufficient to form a clear image.
Of course, those skilled in the art may also set the polarization directions of the light that can be transmitted by the secondary polarization part 401 of the first polarizer 40 and the secondary polarization part 401 of the second polarizer 50 to be the same, and in the privacy-protection state, the liquid crystal in the non-display area NA can change the polarization direction of the incident light that passes through the first polarizer 40 and make the incident light intersect with the polarization direction of the second polarizer 50.
