In recent years, many manufacturers have conducted intensive research on the technology of Camera Under Panel (CUP), and the CUP is considered to be the best solution for the true full-screen.

However, because the area of the off-screen camera in the existing display screen usually has the light-transmitting holes and the opaque pixel structures which are periodically arranged, so that the area can be equivalent to a two-dimensional grating in the imaging lens, the off-screen imaging technology is affected by the low transmittance of the display screen and the diffraction phenomenon generated by the periodically arranged array holes, which causes the degradation of image quality, such as image blurring or glare pollution.

In order to solve the above problems, technicians mainly take the software aspects and have developed a series of image processing algorithms, such as an AI algorithm set of AWB or HDR to improve the imaging effect of the off-screen camera, but the achieved effect is not significant enough, and the diffraction problem introduced by the existence of the display screen cannot be solved fundamentally.

In addition, some manufacturers reduce the density of the pixel structures in the area of the camera under the screen, or optimize the arrangement and circuit design of the pixel structures in the area to improve the diffraction phenomenon caused by the screen grating, but the display effect of the area and the display effect of other areas are too large, so that the acceptable level of users cannot be reached due to too low pixels, and the improvement degree of the imaging quality is very limited.

The area of the conventional display screen under the screen camera is generally composed of two parts: one part is a light hole which is arranged periodically, so that external environment light can firstly pass through the light hole and then pass through the imaging lens group to be transmitted to the CCD sensor, and information of an external object can be imaged on the CCD; the other part is a pixel defining area which can normally display information to be displayed. However, the area of the camera under the screen of the conventional display screen generates a diffraction effect due to the periodic arrangement of the light holes, and the diffraction effect can cause the image quality to be reduced and is accompanied with the problems of glare pollution and the like. In particular, when high contrast information is present in the scene information, such as a high brightness light source, the image may have smear.

In order to solve the above problems, the present application provides a display screen for camera shooting under screen and a camera device under screen, which can directly reduce diffraction efficiency from hardware, so as to fundamentally solve the diffraction problem caused by the existence of the display screen, and contribute to improving the imaging quality of the camera under screen.

Specifically, referring to fig. 1 to 5, an embodiment of the present invention provides an off-screen display 1, which is adapted to cooperate with an off-screen camera 2 to perform off-screen imaging, and the off-screen display 1 may include a screen body 10 and an optical filter assembly 20. The display area 100 of the screen body 10 may include a main display area 110 and an under-screen camera area 120 for corresponding to the under-screen camera 2, and the under-screen camera area 120 is composed of a pixel structure 121 for displaying a picture and a plurality of light-transmitting structures 122 arranged periodically. The optical filter assembly 20 may include a plurality of 4f filter systems 200, and the plurality of 4f filter systems 200 are disposed in the plurality of light-transmitting structures 122 of the under-screen image capture area 120 in a one-to-one correspondence, so that on-screen light passes through the light-transmitting structures 122 and the 4f filter systems 200 are received by the under-screen camera 2 to achieve under-screen image capture.

It should be noted that the main display area 110 mentioned in the present application can be, but is not limited to be, implemented as a normal pixel display area, and the configuration thereof can be the same as that of a general display screen; the under-screen image capturing region 120 is generally surrounded by the main display region 110 and is a pixel display region with light transmission performance, that is, the pixel structure 121 of the under-screen image capturing region 120 is a pixel defining region for displaying screen information (such as a picture, etc.) and is opaque, and the light transmission structure 122 of the under-screen image capturing region 120 is a light transmission region for transmitting light on the screen (such as light incident from the external environment). It can be understood that the design of the driving circuit of the pixel structure 121 in the under-screen image capturing region 120 of the present application is not limited, and a high under-screen image capturing effect can be achieved; but if transparent leads are selected as the leads for the drive circuit, the screen feel can be removed.

In addition, the type of the display screen 1 for under-screen image capture in the present application may not be limited, that is, the screen main body 10 may be an LCD display screen illuminated by an LED, or a display screen illuminated by an OLED or an AMOLED, which is not described herein again.

More specifically, as shown in fig. 3, the 4f filter system 200 may comprise a first microlens 21, a filter aperture 22, and a second microlens 23, wherein the first microlens 21, the filter aperture 22, and the second microlens 23 are coaxially arranged, and the filter aperture 22 is located between the first microlens 21 and the second microlens 23 at a common focal point of the first microlens 21 and the second microlens 23. In this way, each of the light-transmitting structures 122 and the corresponding 4f filter system 200 can jointly form a structure of "light-transmitting unit-microlens-aperture-microlens", so that the light on the screen passing through the light-transmitting unit is firstly converged by the first microlens 21, then passes through the filter aperture 22 to eliminate the light of the higher diffraction order, is converged by the second microlens 23, and then passes through the imaging lens group of the under-screen camera 2 to be received by the sensor of the under-screen camera 2 for photosensitive imaging. It will be appreciated that the filter aperture 22 in the 4f filter system 200 needs to be designed such that the inner region of the filter aperture 22 is light transmissive, while the outer region of the filter aperture 22 is not light transmissive, as by painting or other processes.

Preferably, the first microlenses 21 and the second microlenses 23 are implemented as equal focal length lenses, with the distance between the first microlenses 21 and the second microlenses 23 being equal to twice the focal length of the microlenses. In other words, the focal length of the first microlens 21 is equal to the focal length of the second microlens 23, and the distances between the filter aperture 22 and the first and second microlenses 21, 23 are each equal to a microlens focal length, such that the filter aperture 22 is at the common focal position of the first and second microlenses 21, 23. It is understood that the focal length of the first microlenses 21 and the second microlenses 23 of the present application cannot be too large, typically in the um order.

Alternatively, the first microlenses 21 and/or the second microlenses 23 in the 4f filter system 200 can be, but are not limited to being, implemented as single spherical lenses. Alternatively, in other examples of the present application, the first microlens 21 or the second microlens 23 may also be implemented as an aspheric lens to form an image-side telecentric optical system, so as to avoid optical energy loss or crosstalk problems caused by the deviation of the light rays of different fields of view from the center of the microlens when reaching the second microlens 23.

Exemplarily, in the above-described embodiment of the present application, as shown in fig. 3, the light-transmitting structure 122 of the under-screen imaging region 120 of the screen body 10 may be implemented as an optical window 1221, wherein the optical filter assembly 20 is correspondingly disposed below the under-screen imaging region 120, and the 4f filter systems 200 are aligned with the optical window 1221 of the under-screen imaging region 120 one by one, so as to constitute a structure of "optical window-microlens-aperture-microlens".

Alternatively, the optical filter assembly 20 may be manufactured separately into a filter structure layer, and then aligned and assembled with the screen body 10 to manufacture the display screen 1 for under-screen image capture. Like this, this application make a video recording under the screen and use display screen 1 can directly choose for use conventional display screen, need not to change the internal structure of conventional display screen just can with optical filter component 20 cooperates and realizes better under the screen effect of making a video recording.

Preferably, the light window 1221 is made of a light-transmitting medium to avoid holes in the under-screen image capture area 120 of the screen body 10. For example, the optical window 1221 may be made of transparent glass, or may also be made of an optical filter. It should be noted that in other examples of the present application, the optical window 1221 may also be implemented as a through hole penetrating through the under-screen image capturing area 120, as long as light on the screen is allowed to pass through to propagate under the screen, and details of the present application are not repeated herein.

More preferably, as shown in fig. 3, the optical filter assembly 20 includes a first microlens array layer 210, a filter aperture array layer 220, and a second microlens array layer 230, and the first microlens array layer 210, the filter aperture array layer 220, and the second microlens array layer 230 are sequentially stacked from top to bottom below the under-screen imaging region 120 of the screen body 10, so as to be aligned and assembled below the under-screen imaging region 120 of the screen body 10. In other words, in the optical filter assembly 20: a plurality of the first microlenses 21 are arranged in an array to form a microlens structure layer to form the first microlens array layer 210; a plurality of said filter apertures 22 are arranged in an array in an aperture structure layer to form said filter aperture array layer 220; a plurality of the second microlenses 23 are arranged in an array to form a microlens structure layer to form the second microlens array layer 230. In this way, by correspondingly stacking the first microlens array layer 210, the filter aperture array layer 220, and the second microlens array layer 230, a plurality of 4f filter systems 200 of the optical filter assembly 20 can be formed. It can be understood that, in the optical filter assembly 20 of the present application, the first microlens array layer 210, the filter aperture array layer 220, and the second microlens array layer 230 can be prepared by, but not limited to, photolithography or etching, which is helpful to reduce the difficulty of manufacturing the display screen 1 for photographing under the screen, improve the mass production performance thereof, and have high practicability.

It is noted that, in the above-mentioned embodiment of the present application, the first microlens 21 in the 4f filter system 200 is coaxially aligned close to the optical window 1221 in the screen body 10, and the aperture of the first microlens 21 is preferably equal to or larger than the aperture of the optical window 1221. It is to be understood that in the above examples of the present application, the optical window 1221 may have a circular window; of course, in other examples of the present application, the optical window 1221 may have a window with other shapes, such as a square shape.

In addition, the aperture of the filtering aperture 22 in the 4f filtering system 200 generally relates to the field angle of the imaging lens of the under-screen camera 2 and the period of the light-transmitting structure 122 in the screen body 10, and the under-screen display 1 of the present application should ensure that the chief ray in the maximum field angle can pass through the filtering aperture 22, and can block the diffracted light of the ± 1 st order, the ± 2 nd order or higher diffraction orders introduced by the periodically arranged light-transmitting structure 122.

Illustratively, as shown in fig. 4, taking normal incident light, i.e., on-screen light with an incident angle of zero as an example, since the under-screen image pickup region 120 of the screen body 10 is equivalent to a diffraction grating due to the presence of the light-transmitting structures 122 arranged periodically, the normal incident light is diffracted while passing through the light-transmitting structures 122 of the under-screen image pickup region 120, and the diffracted light satisfies a grating equation: where d is a period of the light-transmitting structure 122, θ is an angle of diffracted light, k is a diffraction order, and λ is a wavelength of incident light.

According to the above-mentioned grating equation, it can be calculated that the distance between the focus of the high-order diffracted light caused by the light-transmitting structure 122 of the off-screen imaging region 120 and the central zero-order diffracted light is about f × tan θ ═ f × k λ/(2 d). Therefore, when the aperture of the filter aperture 22 is smaller than f x λ/d, diffracted light of ± 1 st order, ± 2 nd order or higher diffraction orders of normal incident light will not be transmitted through the filter aperture 22, and diffracted light of zero order of normal incident light can be transmitted through the filter aperture 22 to be converged by the second microlens 23 to be received by the under-screen camera 2.

In addition, the aperture setting of the filtering aperture 22 is also required to avoid the crosstalk problem caused by the incident light with a large viewing angle after passing through the light-transmitting structure 122. As shown in fig. 5, taking an off-axis incident light with a half field angle β as an example, the off-axis incident light may be diffracted when passing through the light-transmitting structure 122, the diffracted lights of different orders may be focused on different focal points after being focused by the first microlens 21, and a position of a focus point of the central zero-order diffracted light deviates from an optical axis by a distance of about f tan β, where f is a focal length of the first microlens 21, and β is a half field angle of the incident light; the diffracted light of higher diffraction order is converged around the position of the convergence point of the central zero-order diffracted light symmetrically around the central zero-order diffracted light, and the distance between the position of the convergence point of the central zero-order diffracted light and the position of the convergence point of the central zero-order diffracted light is larger as the diffraction order is higher. Therefore, the aperture of the filter aperture 22 is larger than 2f tan β to ensure that the central zero-order diffracted light of the off-axis incident light is transmitted. At the same time, the aperture of the filter aperture 22 also needs to be restricted to block out diffracted light of other higher diffraction orders of the off-axis incident light.

In order to verify the effect of the 4f filter system 200 in the display screen 1 for under-screen image pickup of the present application on eliminating the high-order diffracted light, VirtualLab software is adopted in the present application to model and simulate the diffraction conditions before and after the 4f filter system 200 is additionally arranged behind the single light-transmitting structure 122. Fig. 6A shows a schematic optical path diagram of a single light-transmitting structure 122 without the 4f filter system 200, where the optical path system is: the plane wave firstly passes through a diaphragm to generate far field diffraction, and then an ideal lens is used for imaging a far field diffraction pattern on a detector after the diaphragm, wherein the shape of the diaphragm is set to be rectangular, and the diameter of the diaphragm is set to be 50 um. The diffraction pattern as shown in fig. 6B was obtained by the simulation test, and it can be seen from fig. 6B that: the range of the central zero-order diffraction light is about 180un, and the intensity is strongest; the diffraction orders increase from the center to the outside, and the intensity decreases accordingly.

Similarly, fig. 7A shows a schematic optical path diagram of a single light-transmitting structure 122 when a 4f filter system 200 is added, wherein the focal lengths of the first microlens 21 and the second microlens 23 are both set to be 1mm, and the aperture of the filter aperture 22 is set to be 5um, so as to obtain the diffraction pattern shown in fig. 7B through simulation test. Comparing the diffraction pattern shown in fig. 7B with the diffraction pattern shown in fig. 6B, it can be seen that: after the single light-transmitting structure 122 is followed by the 4f filter system 200, the central zero-order diffracted light is substantially unchanged, but the diffracted light of other higher-order diffraction orders is eliminated. In a similar way, this application is in make a video recording under the screen and is in with display screen 1 every in screen main part 10 add behind the light-transmitting structure 122 and establish 4f filtering system 200 also can be right in screen main part 10 the diffraction effect of light-transmitting structure 122 plays certain inhibitory action.

It should be noted that, although the optical filter assembly 20 in the above-mentioned embodiment according to the present application has a layer structure to be attached to the screen body 10 in alignment below the under-screen image capturing region 120, it is only an example, and in other examples of the present application, the 4f filter system 200 in the optical filter assembly 20 may be integrated on the screen body 10, so as to further improve the structural compactness and reduce the thickness of the under-screen image capturing display screen 1.

Specifically, fig. 8 shows a modified embodiment of the under-screen image capture display screen 1 according to the above-mentioned embodiment of the present application, in which the light-transmitting structures 122 of the under-screen image capture area 120 of the screen body 10 are implemented as light-transmitting holes 1222 provided in the pixel structures 121, and the 4f filter systems 200 are assembled in the light-transmitting holes 1222 in a one-to-one correspondence, so that each light-transmitting structure 122 forms a structure of "light-transmitting hole-microlens-aperture-microlens", achieving the effect of blocking higher-order diffracted light.

According to another aspect of the present application, as shown in fig. 9, an embodiment of the present application may further provide an off-screen camera device, which may include the off-screen camera display 1 and the off-screen camera 2 correspondingly disposed below the off-screen camera display 1, and configured to collect on-screen light passing through the off-screen camera display 1 to form an image. Specifically, the under-screen camera 2 aligns with the optical filter component 20 of the under-screen display screen 1 and the under-screen image pickup area 120 of the screen main body 10, and the optical filter component 20 is located between the under-screen image pickup area 120 and the under-screen camera 2, so that the on-screen light firstly penetrates through the optical filter component 20 and then is received by the under-screen camera 2 to realize the under-screen image pickup. It is understood that the under-screen camera 2 may be, but is not limited to be, implemented as a camera module consisting of an imaging lens group and a CCD chip, and of course, in other examples of the present application, the under-screen camera 2 may also adopt other types of photosensitive chips such as CMOS.

It should be noted that the application scenario of the off-screen camera device is not limited in the present application, and the application scenario may be applied to, but not limited to, an application scenario of a mainstream display screen such as a mobile phone, a computer, a television, or a tablet, and the details of the application scenario are not repeated herein. In other words, the under-screen camera apparatus of the present application may also be implemented, but not limited to, as an electronic device, such as a mobile phone, a computer, a television, a tablet, or various robots, etc., configured with the under-screen camera display 1 and the under-screen camera 2.
