Detailed Description

Reference will now be made in detail to embodiments of the present application, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present application and should not be construed as limiting the present application.

The following disclosure provides many different embodiments, or examples, for implementing different features of the application. In order to simplify the disclosure of the present application, specific example components and arrangements are described below. Of course, they are merely examples and are not intended to limit the present application. Further, the present application may repeat reference numerals and/or letters in the various examples. This repetition is for the purpose of simplicity and clarity and does not in itself dictate a relationship between the various embodiments and/or configurations discussed. In addition, examples of various specific processes and materials are provided herein, but one of ordinary skill in the art may recognize the applicability of other processes and/or the use of other materials.

An electronic apparatus 1000 and a display control method thereof according to an embodiment of the present application are described below with reference to fig. 1 to 11.

As shown in fig. 1 and 2, an electronic device 1000 according to an embodiment of the present application may include: a display screen assembly 100 and a camera 200, wherein the display screen assembly 100 may include: LCD body 1, backlight 2, light filling source 3.

As shown in fig. 2 and 3, the backlight plate 2, the light supplement source 3, and the camera 200 are disposed on the back side of the LCD body 1. Here, it should be noted that, in the use process of the electronic device 1000, a side of the electronic device 1000 facing the user is a "front side" (a front side shown in fig. 2), and a side of the electronic device 1000 facing away from the user is a "back side" (a back side shown in fig. 2).

As shown in fig. 2 and fig. 3, the LCD body 1 includes a preset region 101A and a normal display region 101B, specifically, the normal display region 101B includes a color filter 111 (for forming different colors), a liquid crystal layer 131, and a first thin film transistor 121 (which may be used for implementing a driving circuit and a display pixel circuit) sequentially arranged from front to back, and the preset region 101A includes a non-color-resist sheet 112, a scattering layer 132, and a second thin film transistor 122 sequentially arranged from front to back.

In connection with fig. 4 and 5, the scattering layer 132 is switchable between assuming a transparent state and assuming a non-transparent state. For example, the scattering layer 132 may include a mixture 132A and a spacer 132B, the spacer 132B separating the mixture 132A from the liquid crystal layer 131, the mixture 132A including liquid crystal molecules 132A1 and a microsphere polymer 132A2 having a different refractive index than the liquid crystal molecules 132A 1. The diameter of the microsphere polymer 132A2 can be 10-20 μm.

Thus, for the scattering layer 132, the microsphere polymers 132A2 are randomly arranged under the action of no electric field, the refractive index of the randomly arranged microsphere polymers 132A2 is different from that of the liquid crystal molecules 132A1, and incident light is scattered when passing through the scattering layer 132, so that the scattering layer 132 is in a non-transparent state; when a voltage is applied to the scattering layer 132, the microsphere polymers 132a2 are regularly arranged parallel to the electric field under the action of the electric field, and at this time, the refractive index of the liquid crystal molecules 132a1 in the ordinary direction is complementary to the refractive index of the microsphere polymers 132a2, so that the refractive index of incident light in the normal direction is not changed, and no scattering phenomenon occurs, and therefore, the incident light can penetrate through the scattering layer 132 without changing the direction and is in a transparent state. In short, the scattering layer 132 is switched between the non-transparent state and the transparent state by matching the refractive index of the microsphere polymer 132a2 before and after electrification with the refractive index of the liquid crystal molecules 132a 1.

Returning to fig. 2 and 3, the backlight plate 2 has a through hole 20 opposite to the predetermined region 101A, the light supplement source 3 is a multi-color light source capable of field sequential display and is adapted to emit light to the predetermined region 101A through the through hole 20, the light supplement source 3 and the backlight plate 2 are two independent components, which are not only physically independent from each other, but also electrically independent from each other, and cannot be understood as two parts of the same component.

In addition, it should be noted that the supplementary light source 3 refers to a light source including at least three colors of red, green and blue, that is, the supplementary light source 3 may include other colors of light (e.g., white light, yellow light, etc.) besides the three colors of red, green and blue. Further, the "field sequential display manner" means: a color picture (frame) is formed by sequentially dividing colors of red (R), green (G), blue (B), white (W), yellow (Y) and the like into a plurality of pictures (fields) in time sequence, and then sequentially switching the pictures (fields) at a high speed.

For example, when the complementary light source 3 is a three-color R/G/B light source including only R, G, B three primary colors, the time displayed at each field is 1/3 of the time displayed at one frame, three fields constitute one frame, and so on. For another example, when the complementary light source 3 is an R/G/B/W four-color light source including only R, G, B, W four primary colors, the time displayed in each field is 1/4 of the time displayed in one frame, four fields constitute one frame, and the rest is similar. The contrast normal display mode is that all colors are displayed together. Therefore, the input cost can be reduced when the fill-in light source 3 is a three-color R/G/B light source, and the display brightness can be improved when the fill-in light source 3 is a four-color R/G/B/W light source.

The display principle of the constant display area 101B is: when the backlight 2 provides a surface light source to the normal display region 101B, the LCD body 1 controls the liquid crystal layer 131 to invert through the electrodes, so that the light of the backlight 2 passes through, and the color filter 111 determines the color of the light after passing through different color resistances, thereby realizing the image display of color type and brightness. The "backlight 2" may include an upper brightness enhancement film, a lower brightness enhancement film, a diffusion film, a light guide plate, a reflection sheet, a frame, and the like.

The display principle of the preset area 101A is as follows: when a voltage is applied to the scattering layer 132 to make the scattering layer 132 in a non-transparent state, the light source is provided to the predetermined region 101A by the complementary light source 3, and image display can be realized by field sequential display (for example, by high-frequency sequential light emission of R/G/B three-color light sources) of the complementary light source 3 in cooperation with the non-color-resist sheet 112.

The non-display principle of the preset area 101A is as follows: when no voltage is applied to the scattering layer 132 to make the scattering layer 132 in a transparent state, the scattering layer 132 has a very high transmittance (for example, the transmittance may reach more than 80%), and the light supplement source 3 is matched with the non-color-resist sheet 112, so that no image is displayed in the predetermined region 101A. At this time, when the camera 200 is disposed opposite to the through hole 20, the camera 200 may obtain light in an external environment through the through hole 20 and the preset region 101A having high light transmittance, thereby implementing a camera function of the camera 200.

Therefore, according to the electronic device 1000 of the embodiment of the application, the preset region 101A without the backlight plate 2 for providing the surface light source is designed on the LCD body 1, and since the preset region 101A includes the scattering layer 132 capable of switching between the transparent state and the non-transparent state, when the scattering layer 132 is in the transparent state, the camera 200 can be hidden at the back side of the LCD body 1 for normal shooting, and when the scattering layer 132 is in the non-transparent state, the camera 200 can be matched with the light supplement source 3 and the non-color resistance sheet 112 capable of displaying in the field sequential manner, so that the preset region 101A can display a picture, and the camera 200 can be hidden at the back side of the picture displayed by the preset region 101A.

As shown in fig. 6, the electronic apparatus 1000 according to the embodiment of the present application may have the following display control method. The display control method is used for controlling the electronic equipment 1000 to at least realize a front shooting mode and a front display mode, wherein the display control method comprises the following steps:

in the front display mode, the backlight plate 2 and the light supplement source 3 are lightened, and the scattering layer 132 is controlled to be in a non-transparent state; that is, on the one hand, the backlight 2 is turned on to provide a surface light source to the normal display region 101B to normally display a picture in the normal display region 101B, and on the other hand, the scattering layer 132 is rendered non-transparent without applying an electric field thereto, and the supplemental light source 3 is controlled to perform field sequential display in cooperation with the non-color-resist sheet 112 to display a picture in the predetermined region 101A. Therefore, the whole LCD body 1 can display a complete picture, and the camera 200 can be hidden under the picture.

In the front image pickup mode, the backlight 2 is turned on, the light supplement source 3 is turned off, and the scattering layer 132 is controlled to be transparent. That is to say, on the one hand, the backlight plate 2 is turned on to provide a surface light source to the normal display region 101B, so that the normal display region 101B displays a normal picture, and on the other hand, the light supplement source 3 is turned off, and simultaneously, a voltage is applied to the scattering layer 132, so that the scattering layer is in a transparent state, and the non-color-resistance sheet 112 is matched, so that the preset region 101A is in a transparent state, and light in an external environment can enter the camera 200 through the preset region 101A to form an image. Thus, the off-screen front camera mode can be realized.

In addition, it should be noted that "an alternative of the fill light source 3", "a relative position relationship between the fill light source 3 and the through hole 20", and "a relative position relationship between the camera 200 and the through hole 20" may be specifically selected according to actual requirements, and will be described in detail later, and will not be described herein again.

Therefore, according to the electronic device 1000 of the embodiment of the present application, the front camera mode is implemented by hiding the camera 200 at the back side of the LCD body 1, so that a hole for installing the camera 200 does not need to be formed on the LCD body 1, and the design requirement of the electronic device 1000 for the whole screen occupation ratio is further satisfied. In addition, the light supplement source 3 is set to supplement light for the backlight-free preset area 101A, so that the LCD body 1 can display a complete picture after the pre-shooting mode is finished.

In short, according to the electronic device 1000 of the embodiment of the present application, the camera 200 can be hidden under the screen, so as to achieve the effect of shooting under the screen, meet the design requirement of 100% of the total screen area ratio, avoid various deficiencies of the pop-up front camera in the prior art, and meet the normal display requirement of the electronic device 1000.

In some alternative embodiments of the present application, as shown in fig. 4, the scattering layer 132 may include two glass substrates 132C disposed on front and rear sides (upper and lower sides as shown in fig. 4) of the isolation ring 132B, and a closed space is defined between the two glass substrates 132C and the isolation ring 132B to encapsulate the mixture 132A. Thereby, modularization of the scattering layer 132 can be achieved, facilitating assembly thereof. Of course, the present application is not limited thereto, and in other embodiments of the present application, the scattering layer 132 may not include the two glass substrates 132C, as shown in fig. 5.

In some alternative embodiments of the present application, as shown in fig. 4 and 5, the non-resist sheet 112 includes a first glass substrate 1120, the color filter 111 includes a second glass substrate 1110, and the first glass substrate 1120 and the second glass substrate 1110 are two parts of a single glass substrate. That is, the color filter 111 and the non-color resist sheet 112 may be an integral component, and for example, when the color filter 111 is processed, the black matrix 111A and the color layer 111B of a certain area of the color filter 111 may be deleted so that the area may serve as the non-color resist sheet 112.

Therefore, when the display panel assembly 100 is manufactured, the color filter 111 and the non-color-resist sheet 112 are integrated components, so that the assembly efficiency can be greatly improved, and the color filter 111 and the non-color-resist sheet 112 are integrated components without assembly connection gaps, so that the reliability of the overall structure and the overall display effect of the LCD body 1 can be improved.

In some alternative embodiments of the present application, as shown in fig. 4 and 5, the first thin film transistor 121 and the second thin film transistor 122 are integrated on the same glass substrate 123. That is, some regions on one glass substrate 123 may be provided with the first thin film transistor 121, while other regions on the glass substrate 123 are provided with the second thin film transistor 122, thereby constituting a complete, non-detachable TFT assembly.

Therefore, when the display panel assembly 100 is manufactured, the first thin film transistor 121 and the second thin film transistor 122 are integrated on the same glass substrate 123 to form a complete component, so that the assembly efficiency can be greatly improved, and the reliability of the whole structure can be improved.

Of course, the present application is not limited thereto, and in other embodiments of the present application, the first glass substrate 1120 and the second glass substrate 1110 may be two separate components, and the first thin film transistor 121 and the second thin film transistor 122 may also be integrated on different glass substrates 123, respectively.

In some alternative embodiments of the present application, as shown in fig. 2 and 3, the complementary light source 3 may be a point light source 31 (the definition of a point light source is common general knowledge). Therefore, the light supplement source 3 is simple and small in structure and easy to arrange. Moreover, the light emitted by the point light source 31 has good divergence, and can effectively and comprehensively cover the preset area 101A, so that the preset area 101A can be well displayed in the front shooting mode and the front display mode, and the whole display effect of the LCD body 1 is improved. Here, it should be noted that, in the present application, the number and arrangement of the point light sources 31 are not limited.

Of course, the present application is not limited thereto, and other light sources may be adopted as the light supplement source 3. For example, in some alternative embodiments of the present application, as shown in fig. 7 and fig. 8, the light supplement source 3 may also be a surface light source 32 (the definition of the surface light source is common knowledge), and the electronic device 1000 further includes a light guide structure 4 for guiding the light emitted from the surface light source 32 to the preset region 101A. Therefore, considering that the light emitted by the surface light source 32 is parallel light and non-spherical divergent light, by arranging the light guide structure 4, the light emitted by the surface light source 32 can fully, comprehensively, effectively and uniformly cover the preset area 101A, so that the preset area 101A can be well displayed in the front shooting mode and the front display mode, and the overall display effect of the LCD body 1 is improved. Here, in the present application, the shape, number, and arrangement of the surface light source 32 are not limited.

In some embodiments of the present application, as shown in fig. 2, at least a portion of the camera head 200 is located within the perforation 20. Therefore, the camera 200 can skillfully utilize the space in the through hole 20, so that the matching compactness of the camera 200 and the through hole 20 is improved, the overall structural compactness of the electronic device 1000 is greatly improved, the light and thin development requirements of the electronic device 1000 are met, and the user can hold the electronic device more conveniently. Of course, the present application is not limited thereto, and in other embodiments of the present application, the camera 200 may not be located in the through hole 20 (as shown in fig. 7) at all to meet different practical requirements.

In some embodiments of the present application, as shown in FIG. 2, the hole depth H0 of the perforation 20 is less than the height H1 of the camera head 200, such that a portion of the camera head 200 is located within the perforation 20 and another portion of the camera head 200 is located outside the perforation 20. That is, the height H1 of the camera head 200 exceeds the hole depth H0 of the through hole 20, so that the camera head 200 cannot be completely received within the through hole 20. Thus, the disassembly and assembly of the camera 200 and the layout of the leads are facilitated. Of course, the present application is not limited thereto, and in other embodiments of the present application, the height H1 of the camera 200 may be smaller than the hole depth H0 of the through hole 20, so that the camera 200 may be completely accommodated in the through hole 20, thereby improving the overall structural compactness of the electronic device 1000, meeting the requirement of the electronic device 1000 for light and thin development, and being more convenient for a user to hold and use.

In some embodiments of the present application, as shown in fig. 2 and 3, the projection of the camera 200 is entirely located within the preset region 101A when projected in the thickness direction of the LCD body 1 (i.e., projected in the direction from the front side to the back side shown in fig. 2). Therefore, the camera 200 can fully utilize the space in the through hole 20, so that the matching compactness of the camera 200 and the through hole 20 is improved, the overall structural compactness of the electronic device 1000 is greatly improved, the light and thin development requirements of the electronic device 1000 are met, and the user can hold the electronic device more conveniently.

In some embodiments of the present application, as shown in fig. 2 and 3, at least a portion of the light supplement source 3 is disposed within the perforation 20. Therefore, the light supplement source 3 can skillfully utilize the space in the through hole 20, so that the matching compactness of the light supplement source 3 and the through hole 20 is improved, the integral structural compactness of the electronic device 1000 is greatly improved, the light and thin development requirement of the electronic device 1000 is met, and the user can hold the electronic device more conveniently. Of course, the present application is not limited thereto, and in other embodiments of the present application, the fill light source 3 may not be located in the through hole 20 (as shown in fig. 7) at all to meet different practical requirements.

In some embodiments of the present disclosure, as shown in fig. 2 and 3, the hole depth H0 of the through hole 20 is smaller than the height H2 of the light supplement source 3, so that a portion of the light supplement source 3 is located outside the through hole 20, that is, the height H2 of the light supplement source 3 exceeds the hole depth H0 of the through hole 20, so that the light supplement source 3 cannot be completely received in the through hole 20. Therefore, the light supplement source 3 is convenient to assemble and disassemble and lead layout. Certainly, the present application is not limited to this, in other embodiments of the present application, the height H2 of the light supplement source 3 may also be smaller than the hole depth H0 of the through hole 20, so that the light supplement source 3 may be completely accommodated in the through hole 20, thereby improving the overall structural compactness of the electronic device 1000, meeting the requirement of the light and thin development of the electronic device 1000, and being more convenient for a user to hold and use.

In some embodiments of the present application, as shown in fig. 2 and 3, the projection along the thickness direction of the LCD body 1 (i.e., the projection along the direction from the front side to the back side shown in fig. 2) is completely located within the predetermined region 101A. From this, light filling source 3 can make full use of the space in perforation 20 to improve light filling source 3 and perforation 20 complex compactedness, make the holistic compact structure of electronic equipment 1000 improve by a wide margin, satisfy the frivolous development requirement of electronic equipment 1000, be convenient for more that the user holds the use.

In some embodiments of the present disclosure, the cross-sectional profile of the predetermined area 101A (i.e., the cross-sectional profile of the perforation 20) is defined by a straight line segment and/or a curved line segment, that is, the cross-sectional profile of the predetermined area 101A may be defined by a curved line segment (e.g., fig. 8), the cross-sectional profile of the predetermined area 101A may be defined by a straight line segment (e.g., fig. 9), and the cross-sectional profile of the predetermined area 101A may be defined by a combination of a straight line segment and a curved line segment (e.g., fig. 10). Therefore, the cross-sectional profile of the preset region 101A can be flexibly designed according to the shape of the LCD body 1 and the arrangement position of the preset region 101A on the LCD body 1, so as to achieve the optimal display and image pickup effects.

For example, in some specific examples of the present application, the cross-sectional profile of the preset area 101A (i.e., the cross-sectional profile of the through-hole 20) may be rectangular, or circular (as shown in fig. 8), or regular polygonal (as shown in fig. 9), or oval, or semicircular, or racetrack-shaped (as shown in fig. 10), and so on, thereby facilitating processing and providing an aesthetically pleasing appearance. Of course, the present application is not limited thereto, and in other embodiments of the present application, the cross-sectional profile of the preset area 101A (i.e. the cross-sectional profile of the perforation 20) may also be configured into other special shapes, such as a crescent shape, etc., to better meet different practical requirements.

According to the electronic device 1000 of the embodiment of the application, the preset region 101A may be disposed at various positions.
