Description

Technical Field

[0001] The present invention generally relates to a display device and a method for blurring a boundary line in an under-display camera (CUD) device. In particular, the present invention is directed to a method used in an under-display camera device to blur a distinct boundary line between a sensor area and a display area in a display device by adjusting the gamma level of pixel units.

Background Art

[0002] To obtain better display quality, it may be advantageous to design the camera of a mobile phone to be hidden under the display panel. However, some light incident on the camera may be blocked by pixels, and the transparent material of organic light-emitting diodes (OLEDs) is still too expensive to be applied to ordinary products.

[0003] To solve such problems, an incomplete sub-pixel layout may be proposed to hide the camera under the panel. In addition, in the panel, some pixels in the area of the under-display camera are cut off to facilitate the normal function of the camera.

[0004] As Figure 1 shown, such an incomplete sub-pixel layout may cause a contour issue on the boundary line 11 between the under-display camera area 10 and the normal area 20. Figure 1 The figure shows that there is an obvious visual difference between the under-display camera area 10 and the normal area 20, that is, the visual presence of the boundary line 11, so the visual rendering quality of the panel 1 is endangered in the presence of the under-display camera area 10.

Summary of the Invention

[0005] In view of the above, a first aspect of the present invention proposes a novel display device that can improve the visual rendering quality of an under-display camera device in the presence of an under-display camera area, for example, minimizing the visual presence of the under-display camera area. In the case where the under-display camera area is visually imperceptible, the boundary line is blurred to hide the under-display camera area. A second aspect of the present invention proposes a novel method for blurring the boundary line in an under-display camera device to improve the visual rendering quality of the under-display camera device in the presence of an under-display camera area.

Detailed implementation manners

[0073] In order to improve the display quality, the present invention provides an adjustment method to blur the boundary lines in the under-screen camera area in the presence of the under-screen camera device, for example, to weaken or further eliminate the visual presence of the undesired under-screen camera area. Figure 2 It is an illustration of the flowchart of the method for blurring the boundary lines in the under-screen camera device of the present invention. Figures 3 to 4 It is an example illustrating the operation process for blurring the boundary lines in the under-screen camera device of the present invention.

[0074] Please refer to Figure 2, first perform step 101. Step 101 represents the step of inputting multiple original pixel units. The original pixel units can be pixels or sub-pixels of a display device. The display device can correspond to the under-display camera device 100 shown in Figure 3 . For example, there are multiple pixel units in the under-display camera device 100. A pixel unit can be a pixel or a sub-pixel having a predetermined color and a predetermined brightness. A pixel can include multiple sub-pixels, and each sub-pixel can emit light of a certain color, such as red (referred to as R), green (referred to as G), blue (referred to as B), or another suitable color, but the present invention is not limited thereto. In other words, step 101 can also be referred to as inputting R / G / B information.

[0075] Please refer to Figure 3 . Figure 3 The upper view of the under-display camera device according to an example of the present invention is shown. First, provide the under-display camera device 100. The under-display camera device 100 can include a display panel 101 for displaying pictures or images, such as the image 103 shown in Figure 1 . The under-display camera device 100 can further include other suitable components, such as an input unit (not shown), an output unit (not shown), or a control unit (not shown), but the present invention is not limited thereto. The display panel 101 can include multiple functional areas, such as a sensor area 110, a blurring area 120, and a display area 130, but the present invention is not limited thereto. In some embodiments of the present invention, the sensor area 110 can be surrounded by the blurring area 120, and the blurring area 120 can be surrounded by the display area 130. In some embodiments of the present invention, the blurring area 120 can be in the form of a hollow circle 120H. The hollow circle 120H can include an inner concentric circle 121 and an outer concentric circle 122. The inner concentric circle 121 can have a center 111 of the inner concentric circle 121, such that the center 111 can also be the center of the outer concentric circle 122.

[0076] The display panel 101 can include an image sensor 112 disposed in the sensor area 110. The image sensor 112 can be at least partially disposed in the sensor area 110 or completely disposed in the sensor area 110. The image sensor 112 can be used as a camera in the under-display camera device 100.

[0077] As described above, there are multiple pixels or sub-pixels in the display device 100. Different pixels or different sub-pixels in different regions of the display device 100 can form different pixel sets. In some embodiments of the present invention, at least one sensor pixel group 113 can be disposed in the sensor region 110 adjacent to the blurring region 120. In other words, the sensor pixel group 113 can be disposed at the inner concentric circle 121, that is, at the boundary line between the sensor region 110 and the blurring region 120. The sensor pixel group 113 can include one or more sensor pixel units. Figure 4 The illustrated sensor pixel group 113 can include multiple sensor sub-pixels, but the present invention is not limited thereto.

[0078] In some embodiments of the present invention, at least one blurring pixel group 123 can be disposed in the blurring region 120. In other words, the blurring pixel group 123 can be disposed between the inner concentric circle 121 and the outer concentric circle 122, that is, it can be disposed between the sensor region 110 and the display region 130. The blurring pixel group 123 can include one or more blurring pixel units. Figure 4 The illustrated blurring pixel group 123 can include multiple sensor sub-pixels, but the present invention is not limited thereto.

[0079] In some embodiments of the present invention, at least one display pixel group 133 can be disposed in the display region 130 adjacent to the blurring region 120. For example, the display pixel group 133 can be disposed at the outer concentric circle 122, that is, at the boundary line between the display region 130 and the blurring region 120. The display pixel group 133 can include one or more display pixel units. Figure 4 The illustrated display pixel group 133 can include multiple display sub-pixels, but the present invention is not limited thereto.

[0080] In some embodiments of the present invention, there can also be a straight line 102 passing through the sensor pixel group 113, the blurring pixel group 123, and the display pixel group 133. In some embodiments of the present invention, the straight line 102 can further pass through the center 111 of the inner concentric circle 121, the sensor pixel group 113, the blurring pixel group 123, and the display pixel group 133, such that the blurring pixel group 123 can be disposed between the sensor pixel group 113 and the display pixel group 133. The blurring pixel group 123 can include one or more blurring pixel units. In some embodiments of the present invention, Figure 4 The illustrated minimum distance between the display pixel group 133 and the sensor pixel group 113 is 1, the minimum distance between the blurring pixel group 123 and the sensor pixel group 113 is Z, and the minimum distance between the blurring pixel group 123 and the display pixel group 133 is (1 - Z).

[0081] Figure 4 Illustration of the Figure 3 under-screen camera device 100 according to the present invention along line 102. The sensor pixel group 113 may include one or more sensor pixel units to form a unit cell. In one embodiment of the present invention, the active sensor pixels and the inactive sensor pixels in the sensor area 110 may jointly form a pattern or may be regularly arranged. The unit cell including the active sensor pixels and the inactive sensor pixels to represent the pattern or arrangement of the smallest repeating unit is represented by one of the sensor pixel groups 113. For example, the sensor pixel group 113 may include n active sensor pixels and m inactive sensor pixels, where n is an integer not less than 1 and m is an integer not less than 1. In another embodiment of the present invention, Figure 4 Illustration shows that the sensor pixel group 113 may include four sensor sub-pixels, that is, n + m = 4, but the present invention is not limited thereto. For example, the sensor pixel group 113 may include sensor sub-pixel 114, sensor sub-pixel 115, sensor sub-pixel 116, and sensor sub-pixel 117, regardless of the colors of the four sensor sub-pixels.

[0082] Similarly, the blurring pixel group 123 may include one or more blurring pixel units to form a unit cell. The number of blurring pixel units in a unit cell is the same as the number of sensor pixel units in a unit cell. For example, Figure 4 Illustration shows that the blurring pixel group 123 may include four blurring sub-pixels to correspond to the four sensor sub-pixels in the sensor pixel group 113, regardless of the colors of the four blurring sub-pixels. For example, the blurring pixel group 123 may include blurring sub-pixel 124, blurring sub-pixel 125, blurring sub-pixel 126, and blurring sub-pixel 127, but the present invention is not limited thereto.

[0083] Similarly, the display pixel group 133 may include one or more display pixel units to form a unit cell. The number of blurring pixel units in a unit cell is the same as the number of display pixel units in a unit cell. For example, Figure 4The illustration shows that the display pixel group 133 may include four display sub-pixels corresponding to the four sensor sub-pixels in the sensor pixel group 113, regardless of the colors of the four display sub-pixels. For example, a display pixel group 133 may include a display sub-pixel 134, a display sub-pixel 135, a display sub-pixel 136, and a display sub-pixel 137, but the present invention is not limited thereto.

[0084] As described above, an image sensor 112 is provided in the sensor area 110, and a pixel unit occupied by a part of the image sensor 112 can be a pinhole (represented by a dot) to allow incident light to reach the image sensor 112 to form a part of an image. Due to the presence of one or more pinholes (i.e., Figure 1 one or more points represented by the under-display camera area 10 in ), one or more sensor pixel units in the sensor area 110 become invalid sensor pixel units because these sensor pixel units corresponding to the points can no longer emit light. Figure 1 The illustration shows that the area corresponding to the sensor area 110 and in a dot-like visual form corresponds to the pinholes of the invalid sensor pixel units.

[0085] Therefore, the sensor area 110 including the image sensor 112 may visually exhibit some effective sensor pixels and some invalid sensor pixels. An effective sensor pixel can be represented as a sensor pixel unit capable of emitting light of any suitable color. An invalid sensor pixel can be represented as a sensor pixel unit that cannot emit light at all. For example, an invalid sensor pixel can be represented as a pixel unit in the sensor area 110 represented by the image sensor 112 and occupied by a pinhole, rendering the function of this sensor pixel unit invalid. The set of invalid sensor pixels in the sensor area 110 may unfavorably change the predetermined visual presentation sense of a given pattern, as Figure 1 shown.

[0086] Since an invalid sensor pixel has no brightness (no available illumination), the total brightness of the sensor pixel group 113 (i.e., a unit) may inevitably be reduced based on the presence of invalid sensor pixels in the sensor pixel group 113. And the more invalid sensor pixels there are, the smaller the total brightness of the sensor pixel group 113.

[0087] To balance the reduction in illumination caused by the presence of invalid sensor pixels, all valid sensor pixels in the sensor pixel group 113 can have the maximum sensor pixel brightness value SV, while all invalid sensor pixels in the sensor pixel group 113 will have the minimum sensor pixel brightness value 0. The maximum pixel brightness value can represent the maximum grayscale 255 equal to an intensity of 100%. The minimum pixel brightness value can refer to the minimum grayscale 0 equal to an intensity of 0%. Since the concepts of grayscale or intensity are well known in the art, their details will not be elaborated. In other words, the brightness value of a sensor pixel unit can be SV or 0, so SV can be equal to a brightness value of 100.

[0088] Therefore, the present invention provides the following procedure to mitigate or further eliminate the adverse visual interference of invalid sensor pixels in the sensor area 110. First, as Figure 2 shown, step 201 is performed. First, the display pixel brightness value DV is determined. The display pixel brightness value DV preferably relates to the sensor pixel brightness value SV.

[0089] Due to the presence of one or more pinholes, not every sensor pixel unit in the sensor area 110 is a valid sensor pixel. On the contrary, the display pixel group 133 is disposed in the display area 130 used as a general display area. Therefore, each display pixel unit in the display area 130 is a valid display pixel capable of emitting light of any suitable color in the absence of invalid display pixels. In some embodiments of the present invention, if the sensor pixel group 113 includes n valid sensor pixels and m invalid sensor pixels, then the display pixel group 133 can similarly and correspondingly include n + m valid display pixels and no invalid display pixels.

[0090] To exhibit visual uniformity, the visual brightness of the display pixel group 133 preferably approaches or equals the visual brightness of the sensor pixel group 113, so that the display pixel brightness value DV can be determined. For example, the display pixel brightness value DV can be proportionally reduced relative to the sensor pixel brightness value SV. The sensor pixel brightness value SV can then represent the result corresponding to the under-screen camera.

[0091] If the sensor pixel group 113 includes n effective sensor pixels and m ineffective sensor pixels, the display pixel brightness value DV of the display pixel unit can be determined according to the principle of DV = [n / (n + m)] × (maximum pixel brightness value SV). For example, if SV is set to 100, then DV = [n / (n + m)] × 100. The display pixel brightness value DV that satisfies the foregoing relationship can ensure visually consistent brightness in the display area 130 relative to the sensor area 110. After the foregoing steps, the brightness of the display pixel units in the display area 130, for example, can be made consistent and normalized, so that they can share the same display pixel brightness value DV and have uniform brightness in the display area 130. Therefore, the display pixel brightness value DV can represent the normal result or the normalized result.

[0092] Secondly, as Figure 2 shown, after performing step 201, step 301 is performed. After determining the display pixel brightness value DV of the display pixel unit, the blurred pixel brightness value BV of the blurred pixel unit is determined. The blurred pixel brightness value BV can be determined by aligning the brightness of the blurred pixel from the maximum sensor pixel brightness value SV to the display pixel brightness value DV. This is an adjustment operation for brightness alignment of the blurred area 120 relative to the sensor area 110 and relative to the display area 130.

[0093] Alternatively, in order to balance the brightness difference of the pixel units between the sensor area 110 and the display area 130, the illumination, for example, the brightness of each blurred pixel unit in the blurred area 120, can have a specific blurred pixel brightness value BV according to the display pixel brightness value DV and the sensor pixel brightness value SV. For example, the blurred pixel brightness value BV is not greater than the maximum sensor pixel brightness value SV and not less than the corresponding display pixel brightness value DV, so as to form a smooth brightness gradient that gradually changes from SV to DV. Therefore, a brightness gradient of the pixel units can be formed along the straight line 102, so that the poor visual presentation of a given image caused by ineffective sensor pixels in the sensor area 110 can gradually weaken and converge to the display area 130 through the blurred area 120. In other words, the brightness gradient of the pixel units can be used to make the boundary line of the under-screen camera area, such as Figure 1 shown by the obvious boundary line 11, become blurred, so that the original boundary line may become less obvious visually or further become substantially invisible.

[0094] A blurred pixel group 123 forming a unit unit is disposed in a blurred area 120 and is located between a sensor pixel group 113 and a display pixel group 133, for example, exactly between the sensor pixel group 113 and the display pixel group 133. Each pixel unit in the blurred pixel group 123 has an independent blurred pixel brightness value BV. The respective independent blurred pixel brightness values BV are calculated to be aligned with the SV and the DV. The respective blurred pixel brightness values BV are determined such that the boundary line of the inner concentric circle 121 becomes blurred. A unit unit may include n + m sub-pixels regardless of the color of the sub-pixels, and the n + m sub-pixels may be arranged to form a pattern or in sequence, for example, arranged according to their locus.

[0095] For example, a unit unit in the sensor pixel group 113 may include n effective sensor pixels and m ineffective sensor pixels, where n is an integer not less than 1 and m is an integer not less than 1. Thus, a unit unit may correspondingly include n + m blurred pixels located in a blurred pixel group 123, or may correspondingly include n + m display pixels located in the display area 130. A certain blurred pixel in a unit unit may exclusively correspond to a specific sensor pixel and a corresponding specific display pixel. For example, the blurred pixel at the first locus in a unit unit may correspond to the sensor pixel at the first locus in another unit unit along the straight line 102 and correspond to the display pixel at the first locus in another unit unit. And the blurred pixel at the second locus in a unit unit may correspond to the sensor pixel at the second locus in another unit unit along the straight line 102 and correspond to the display pixel at the second locus in another unit unit, and so on.

[0096] Then, as Figure 2 shown, step 401 is executed after step 301. Step 401 may be an adjustment calculation, for example, performing one or more weighted calculations. Such weighted calculations may involve one or more weights. One or more weights may involve dimensional measurements such as distance, so that the brightness of the sub-pixels in the blurred area 120 can be adjusted according to the distance to a reference point, but the present invention is not limited thereto.

[0097] For example, a specific blurred pixel brightness value BV can be determined based on the weight value Z, the corresponding sensor pixel brightness value SV, and the corresponding display pixel brightness value DV, satisfying a linear weighted calculation: BV = (1 - Z) × SV + Z × DV, but the present invention is not limited thereto. The blurred pixel brightness value BV can represent the gamma level of the blurred pixels in the blurred pixel group 123, but the present invention is not limited thereto. Along the straight line 102, the minimum distance between a display pixel group 133 and a sensor pixel group 113 is 1, the minimum distance between a blurred pixel group 123 and a sensor pixel group 113 is Z and is used as the weight value in this example, and the minimum distance between a blurred pixel group 123 and a display pixel group 133 is (1 - Z), but the present invention is not limited thereto. When implementing the method of the present invention, the actual minimum distance between the display pixel group 133 and the sensor pixel group 113 is obtained according to the actual situation at the time of implementation and can be determined by those of ordinary skill in the art as long as this minimum distance is sufficient for implementing the present invention. In other words, the present invention introduces a weight value related to the under-screen camera to determine the blurred pixel brightness value BV, but the present invention is not limited thereto.

[0098] As Figure 4 shown, some calculation examples for determining different blurred pixel brightness values BV are presented below according to some embodiments of the present invention. Although the following calculation examples involve the embodiment of n + m = 4, the present invention is not limited to the embodiment of n + m = 4. Any embodiment involving n + m ≥ 2 shall be regarded as falling within the scope of the present invention and the optimization principle.

[0099] First example

[0100] Figure 4The figure shows a sensor pixel group 113 including a first sensor sub-pixel 114, a second sensor sub-pixel 115, a third sensor sub-pixel 116, and a fourth sensor sub-pixel 117, forming a unit 113 regardless of the colors of the four sensor sub-pixels. The four sensor sub-pixels are arranged in a unit with respect to their respective specific positions. A position refers to a location where a specific sensor sub-pixel is arranged along a given straight line in a given unit, or a location that is concerned when determining a pixel brightness value, such as DV or BV. For example, the sensor pixel group 113 including the first sensor sub-pixel 114, the second sensor sub-pixel 115, the third sensor sub-pixel 116, and the fourth sensor sub-pixel 117 may include four corresponding positions, such as the position of the first sensor sub-pixel 114, the position of the second sensor sub-pixel 115, the position of the third sensor sub-pixel 116, and the position of the fourth sensor sub-pixel 117, but the present invention is not limited thereto. In the first example, the first sensor sub-pixel 114, the second sensor sub-pixel 115, and the third sensor sub-pixel 116 are effective sensor pixels, and the fourth sensor sub-pixel 117 is an ineffective sensor pixel, so n = 3 and m = 1.

[0101] First, according to the foregoing principle, the first sensor sub-pixel 114, the second sensor sub-pixel 115, and the third sensor sub-pixel 116 respectively have the maximum sensor pixel brightness value SV (brightness 100), while the fourth sensor sub-pixel 117 has the minimum sensor pixel brightness value 0. The foregoing initial conditions can be simplified and expressed as [sub-pixel (corresponding brightness value)]:

[0102] [114(100), 115(100), 116(100), 117(0)]

[0103] Second, Figure 4 The figure shows a display pixel group 133 including a first display sub-pixel 134, a second display sub-pixel 135, a third display sub-pixel 136, and a fourth display sub-pixel 137, forming a unit 133 regardless of the colors of the four display sub-pixels. The four display sub-pixels are respectively arranged in a unit with respect to their specific positions. Then, the display pixel brightness value DV of the four display sub-pixels is determined according to DV = [n / (n + m)]×100.

[0104] DV134 = [3 / (3 + 1)]×100 = 75, because the first display sub-pixel 134 corresponds to the first sensor sub-pixel 114 in area;

[0105] DV135 = [3 / (3 + 1)]×100 = 75, because the second display sub-pixel 135 corresponds to the second sensor sub-pixel 115 in terms of area;

[0106] DV136 = [3 / (3 + 1)]×100 = 75, because the third display sub-pixel 136 corresponds to the third sensor sub-pixel 116 in terms of area;

[0107] DV137 = [3 / (3 + 1)]×100 = 75, because the fourth display sub-pixel 137 corresponds to the fourth sensor sub-pixel 117 in terms of area.

[0108] The above results can be simplified to:

[0109] [134(75), 135(75), 136(75), 137(75)]

[0110] Third, Figure 4 The figure shows a blurring pixel group 123 including a first blurring sub-pixel 124, a second blurring sub-pixel 125, a third blurring sub-pixel 126, and a fourth blurring sub-pixel 127 to form a unit 123, regardless of the colors of the four blurring sub-pixels. The four display sub-pixels are respectively arranged in a unit with respect to their specific positions. Assuming Z = 0.25, this means that the blurring pixel group 123 is relatively close to the sensor pixel group 113 to determine the blurring pixel brightness value BV1 or BV2 of each blurring sub-pixel, and satisfies the relationship: BV = (1 - Z)×SV + Z×DV. The first blurring pixel brightness value BV1 and the second blurring pixel brightness value BV2 can respectively represent a gamma level.

[0111] BV124 = (1 - 0.25)×100 + 0.25×75 = 93.75, because the first blurring sub-pixel 124 corresponds to the first sensor sub-pixel 114 in terms of area (SV = 100);

[0112] BV125 = (1 - 0.25)×100 + 0.25×75 = 93.75, because the second blurring sub-pixel 125 corresponds to the second sensor sub-pixel 115 in terms of area (SV = 100);

[0113] BV126 = (1 - 0.25)×100 + 0.25×75 = 93.75, because the third blurring sub-pixel 126 corresponds to the third sensor sub-pixel 116 in terms of area (SV = 100);

[0114] BV127 = (1 - 0.25)×0 + 0.25×75 = 18.75, because the fourth blurring sub-pixel 127 corresponds to the fourth sensor sub-pixel 117 in terms of area (SV = 0).

[0115] The above adjustment results can be simplified as:

[0116] [124(93.75), 125(93.75), 126(93.75), 127(18.75)]

[0117] The calculation results are shown in Figure 5 .

[0118] Please note that since the total brightness in each unit 113 / 123 / 133 is the same (300), a uniform visual brightness quality will be produced in different pixel groups.

[0119] Second example

[0120] Figure 4 The figure shows a sensor pixel group 113 including a first sensor sub-pixel 114, a second sensor sub-pixel 115, a third sensor sub-pixel 116, and a fourth sensor sub-pixel 117 to form a unit 113, regardless of the colors of the four sensor sub-pixels. The four sensor sub-pixels are respectively arranged in a unit with respect to their specific positions. In the second example, the first sensor sub-pixel 114 and the fourth sensor sub-pixel 117 are effective sensor pixels, while the second sensor sub-pixel 115 and the third sensor sub-pixel 116 are ineffective sensor pixels, so n = 2 and m = 2.

[0121] First, according to the foregoing principle, the first sensor sub-pixel 114 and the fourth sensor sub-pixel 117 respectively have the maximum sensor pixel brightness value SV (brightness 100), while the second sensor sub-pixel 115 and the third sensor sub-pixel 116 respectively have the minimum sensor pixel brightness value 0. The foregoing initial conditions can be simplified as [sub-pixel (corresponding brightness value)]:

[0122] [114(100), 115(0), 116(0), 117(100)]

[0123] Secondly, Figure 4 The figure shows a display pixel group 133 including a first display sub-pixel 134, a second display sub-pixel 135, a third display sub-pixel 136, and a fourth display sub-pixel 137 to form a unit 133, regardless of the colors of the four display sub-pixels. The four display sub-pixels are respectively arranged in a unit with respect to their specific positions. Then, according to the principle of DV = [n / (n + m)] × 100, the display pixel brightness values DV of the four display sub-pixels are determined.

[0124] DV134 = [2 / (2 + 2)]×100 = 50, because the first display sub-pixel 134 corresponds to the first sensor sub-pixel 114 in terms of area;

[0125] DV135 = [2 / (2 + 2)]×100 = 50, because the second display sub-pixel 135 corresponds to the second sensor sub-pixel 115 in terms of area;

[0126] DV136 = [2 / (2 + 2)]×100 = 50, because the third display sub-pixel 136 corresponds to the third sensor sub-pixel 116 in terms of area;

[0127] DV137 = [2 / (2 + 2)]×100 = 50, because the fourth display sub-pixel 137 corresponds to the fourth sensor sub-pixel 117 in terms of area.

[0128] The above results can be simplified to:

[0129] [134(50), 135(50), 136(50), 137(50)]

[0130] Third, Figure 4 The figure shows a blurring pixel group 123 including a first blurring sub-pixel 124, a second blurring sub-pixel 125, a third blurring sub-pixel 126, and a fourth blurring sub-pixel 127 to form a unit 123, regardless of the colors of the four blurring sub-pixels. The four blurring sub-pixels are respectively arranged in a unit relative to their specific positions. Assuming Z = 0.50, this means that the blurring pixel group 123 is located at an equal distance between the sensor pixel group 113 and the display pixel group 133. Then, according to BV = (1 - Z)×SV + Z×DV, the blurring pixel brightness value BV of each blurring sub-pixel is determined.

[0131] BV124 = (1 - 0.50)×100 + 0.50×50 = 75, because the first blurring sub-pixel 124 corresponds to the first sensor sub-pixel 114 (SV = 100) in terms of area;

[0132] BV125 = (1 - 0.50)×0 + 0.50×50 = 25, because the second blurring sub-pixel 125 corresponds to the second sensor sub-pixel 115 (SV = 0) in terms of area;

[0133] BV126 = (1 - 0.50)×0 + 0.50×50 = 25, because the third blurring sub-pixel 126 corresponds to the third sensor sub-pixel 116 (SV = 0) in terms of area;

[0134] BV127 = (1 - 0.50) × 100 + 0.50 × 50 = 75, because the fourth blurred sub-pixel 127 corresponds to the fourth sensor sub-pixel 117 (SV = 100) in terms of area.

[0135] The above adjustment results can be simplified as:

[0136] [124(75), 125(25), 126(25), 127(75)]

[0137] The calculation results are listed in Figure 6 the

[0138] Please note that since the total brightness in each unit 113 / 123 / 133 is the same (200), a uniform visual brightness quality is produced in different pixel groups.

[0139] The Third Example

[0140] Figure 4 The figure shows a sensor pixel group 113 including a first sensor sub-pixel 114, a second sensor sub-pixel 115, a third sensor sub-pixel 116, and a fourth sensor sub-pixel 117 to form a unit 113, regardless of the colors of the four sensor sub-pixels. The four sensor sub-pixels are respectively arranged in a unit with respect to their specific positions. In the third example, the first sensor sub-pixel 114, the second sensor sub-pixel 115, and the third sensor sub-pixel 116 are invalid sensor pixels, while the fourth sensor sub-pixel 117 is a valid sensor pixel. Therefore, n = 1 and m = 3.

[0141] First, according to the foregoing principle, the first sensor sub-pixel 114, the second sensor sub-pixel 115, and the third sensor sub-pixel 116 respectively have the minimum sensor pixel brightness value of 0, while the fourth sensor sub-pixel 117 has the maximum sensor pixel brightness value SV (brightness 100). The foregoing initial conditions can be simplified as [sub-pixel (corresponding brightness value)]:

[0142] [114(0), 115(0), 116(0), 117(100)]

[0143] Second, Figure 4 The figure shows a display pixel group 133 including a first display sub-pixel 134, a second display sub-pixel 135, a third display sub-pixel 136, and a fourth display sub-pixel 137 to form a unit 133, regardless of the colors of the four display sub-pixels. The four display sub-pixels are respectively arranged in a unit with respect to their specific positions. Then, the display pixel brightness values DV of the four display sub-pixels are determined according to DV = [1 / (1 + 3)] × 100.

[0144] DV134 = [1 / (3 + 1)]×100 = 25, because the first display sub-pixel 134 corresponds to the first sensor sub-pixel 114 in terms of area;

[0145] DV135 = [1 / (3 + 1)]×100 = 25, because the second display sub-pixel 135 corresponds to the second sensor sub-pixel 115 in terms of area;

[0146] DV136 = [1 / (3 + 1)]×100 = 25, because the third display sub-pixel 136 corresponds to the third sensor sub-pixel 116 in terms of area;

[0147] DV137 = [1 / (3 + 1)]×100 = 25, because the fourth display sub-pixel 137 corresponds to the fourth sensor sub-pixel 117 in terms of area.

[0148] The above results can be simplified as:

[0149] [134(25), 135(25), 136(25), 137(25)]

[0150] Third, Figure 4 The figure shows a blurring pixel group 123 including a first blurring sub-pixel 124, a second blurring sub-pixel 125, a third blurring sub-pixel 126, and a fourth blurring sub-pixel 127 to form a unit 123, regardless of the colors of the four blurring sub-pixels. The four blurring sub-pixels are respectively arranged in a unit with respect to their specific positions. Assuming Z = 0.75, this means that the blurring pixel group 123 is located closer to the display pixel group 133, and then the blurring pixel brightness value BV of each blurring sub-pixel is determined according to the principle of BV = (1 - Z)×SV + Z×DV.

[0151] BV124 = (1 - 0.75)×0 + 0.75×25 = 18.75, because the first blurring sub-pixel 124 corresponds to the first sensor sub-pixel 114 (SV = 0) in terms of area;

[0152] BV125 = (1 - 0.75)×0 + 0.75×25 = 18.75, because the second blurring sub-pixel 125 corresponds to the second sensor sub-pixel 115 (SV = 0) in terms of area;

[0153] BV126 = (1 - 0.75)×0 + 0.75×25 = 18.75, because the third blurring sub-pixel 126 corresponds to the third sensor sub-pixel 116 (SV = 0) in terms of area;

[0154] BV127 = (1 - 0.75) × 100 + 0.75 × 25 = 43.75, because the fourth blurred sub-pixel 127 corresponds to the sensor sub-pixel 117 (SV = 100) in terms of area.

[0155] The above adjustment results can be simplified as:

[0156] [124(18.75), 125(18.75), 126(18.75), 127(43.75)]

[0157] The calculation results are listed in Figure 7 as follows.

[0158] Please note that since the total brightness in each unit 113 / 123 / 133 is the same (100), a uniform visual brightness quality is produced in different pixel groups.

[0159] Next, as Figure 2 shown, after performing step 401, step 501 is then performed. For example, the brightness of each pixel unit in the blurred area 120 corresponding to each pixel unit is determined, and the weighted result of each pixel unit in the blurred area 120 is obtained. The newly obtained weighted result of the pixel units in the blurred area 120 can be used to weaken the gradient of the contour to blur the obvious boundary line of the under-screen camera area as Figure 1 shown. For example, in the first instance, the brightness of some exemplary pixel units in the blurred area 120 is determined to obtain the weighted result of the pixel units in the blurred area 120 [124(93.75), 125(93.75), 126(93.75), 127(18.75)]. In the second instance, the brightness of some exemplary pixel units in the blurred area 120 is determined to obtain the weighted result of the pixel units in the blurred area 120 [124(75), 125(25), 126(25), 127(75)]. And in the third instance, the brightness of some exemplary pixel units in the blurred area 120 is determined to obtain the weighted result of the pixel units in the blurred area 120 [124(18.75), 125(18.75), 126(18.75), 127(43.75)].

[0160] The weighted results of the pixel unit group are a set of weighted results corresponding to each pixel unit in the blurring region 120. For example, the set in the first instance is [124(93.75), 125(93.75), 126(93.75), 127(18.75)], the set in the second instance is [124(75), 125(25), 126(25), 127(75)], and the set in the third instance is [124(18.75), 125(18.75), 126(18.75), 127(43.75)]. Each pixel unit located in the blurring region 120 with a weighted result in terms of brightness becomes an adjusted pixel unit corresponding to the relevant pixel unit in a different region. For example, in the first instance, [114(100)-124(93.75)-134(75)] together with the first sensor sub-pixel (under-screen camera) 114 and the normal first display sub-pixel 134 forms the adjusted first blurring sub-pixel 124. In the second instance, [115(0)-125(25)-135(50)] together with the first sensor sub-pixel (under-screen camera) 115 and the normal first display sub-pixel 135 forms the adjusted first blurring sub-pixel 125. In the third instance, [117(100)-127(43.75)-137(25)] together with the first sensor sub-pixel (under-screen camera) 117 and the normal first display sub-pixel 137 forms the adjusted first blurring sub-pixel 127. The results with improved brightness gradients are respectively represented in the first instance, the second instance, or the third instance.

[0161] After going through the foregoing steps, as Figure 2 shown, step 601 is then executed to output multiple adjusted pixel units. Output each sub-pixel corresponding to each RGB (referred to as R / G / B information) obtained after the foregoing steps on the display panel 101. The R / G / B information, in terms of brightness, may include different information types but is independent of their respective color information. For example, the R / G / B information in the sensor region 110 may involve the results of the original under-screen camera, such as the maximum pixel brightness value SV or the minimum pixel brightness value 0. The R / G / B information in the display region 130 may involve a general result, such as the average display pixel brightness value DV obtained according to DV = [n / (n + m)] × (maximum pixel brightness value SV). And the R / G / B information in the blurring region 120 may involve a set of multiple gradient results, such as a set of blurring pixel brightness values BV obtained according to BV = (1 - Z) × SV + Z × DV. Z is a variable corresponding to the position of a given blurring pixel unit.

[0162] Specifically, the blurred pixel brightness value BV is a weighted result based on Z, and each weighted result corresponding to each pixel unit in the blurred area 120 is collected. Therefore, all the weighted results become a set of brightness information related to all pixel units in the blurred area 120, and are used to output multiple adjusted pixel units for display purposes.

[0163] After the foregoing adjustment method, a novel display device 100 is provided to optimize the visual presentation quality of the under-display camera device in the presence of the under-display camera area, for example, to minimize the visual presence of the under-display camera area. Figure 3 The upper view of the under-display camera device according to an example of the present invention is shown. Figure 4 The figure shows according to Figure 3 A partial enlarged view of the under-display camera device along a straight line. The display device 100 of the present invention includes a display panel 101, an image sensor 112, a sensor pixel group 113, a display pixel group 123, and a blurred pixel group 133.

[0164] The display device 100 may be a device with a camera disposed under the display panel. The under-display camera device may include a display panel 101 for displaying pictures or images (such as image 103). The under-display camera device may further include other suitable components, such as an input unit (not shown), an output unit (not shown), or a control unit (not shown), but the present invention is not limited thereto.

[0165] The display panel 101 may include multiple functional areas, such as a sensor area 110, a blurred area 120, and a display area 130, but the present invention is not limited thereto. In some embodiments of the present invention, the sensor area 110 may be surrounded by the blurred area 120, and the blurred area 120 may be surrounded by the display area 130. In some embodiments of the present invention, the blurred area 120 may be in the form of a hollow circle 120H. The hollow circle 120H may include an inner concentric circle 121 and an outer concentric circle 122. The inner concentric circle 121 may have a center 111 of the inner concentric circle 121, so the center 111 may also be the center of the outer concentric circle 122.

[0166] The display panel 101 may include an image sensor 112 disposed in the sensor area 110, and a pixel unit occupied by a part of the image sensor 112 may become a pinhole (dot) to allow incident light to pass through and reach the image sensor 112 to form an image. The image sensor 112 may be at least partially disposed in the sensor area 110, or completely disposed in the sensor area 110. The image sensor 112 may form a plurality of dots and may be used as a camera in the sensor area 110 of the under-display camera device 100. Due to the presence of one or more pinholes, one or more sensor pixel units in the sensor area 110 will become one or more invalid sensor pixel units, such as one or more pinholes, because these invalid sensor pixel units cannot emit light. Figure 1 The figure shows pinholes corresponding to the sensor area 110, presented in the form of a visual dot area, corresponding to invalid sensor pixel units.

[0167] The display device 100 has a plurality of pixels or sub-pixels. Different pixels or different sub-pixels in different areas of the display device 100 form different pixel groups. In some embodiments of the present invention, the sensor pixel group 113 may be disposed in the sensor area 110 and adjacent to the blurring area 120. In other words, the sensor pixel group 113 may be disposed at the inner concentric circle 121, that is, adjacent to the boundary line between the sensor area 110 and the blurring area 120. The sensor pixel group 113 may include one or more sensor pixel units.

[0168] Therefore, the sensor area 110 including the image sensor 112 may visually exhibit some effective sensor pixels and some invalid sensor pixels. Effective sensor pixels may refer to sensor pixel units that can emit light of any suitable color. Invalid sensor pixels may refer to sensor pixel units that do not emit light at all. For example, invalid sensor pixels may refer to pixel units occupied by pinholes, and the pinholes represented by the image sensor 112 in the sensor area 110 will invalidate the original function of the sensor pixel units. The set of invalid sensor pixels in the sensor area 110 may unfavorably change the visually predetermined presentation sense of a given image, as Figure 1 shown.

[0169] A sensor pixel group 113 may include one or more sensor pixel units to form a unit. In an embodiment of the present invention, the effective sensor pixels and the invalid sensor pixels in a sensor area 110 may jointly form a pattern or may be regularly arranged. A unit representing the smallest repeating unit in terms of pattern or arrangement, including the effective sensor pixels and the invalid sensor pixels, is represented by a sensor pixel group 113. For example, the sensor pixel group 113 may include n effective sensor pixels and m invalid sensor pixels, where n is an integer not less than 1 and m is an integer not less than 1. In another embodiment of the present invention, Figure 4 The illustrated sensor pixel group 113 may include four sensor sub-pixels, so n + m = 4, but the present invention is not limited thereto. For example, regardless of the colors of these four sensor sub-pixels, the sensor pixel group 113 may include a sensor sub-pixel 114, a sensor sub-pixel 115, a sensor sub-pixel 116, and a sensor sub-pixel 117.

[0170] The effective sensor pixels in the sensor pixel group 113 may have a maximum sensor pixel brightness value SV. The invalid sensor pixels in the sensor pixel group 113 may have a minimum sensor pixel brightness value of 0. The maximum pixel brightness value may represent the maximum gray scale 255 equal to an intensity of 100%. The minimum pixel brightness value may refer to the minimum gray scale 0 equal to an intensity of 0%. The concepts of gray scale or intensity are well known in the art, and thus the details thereof will not be described in further detail. In other words, the brightness value of a sensor pixel unit may be SV or 0, so SV may be equal to the brightness value 100.

[0171] In some embodiments of the present invention, a display pixel group 133 may be disposed in a display area 130 and adjacent to a blurring area 120. In other words, the display pixel group 133 may be disposed at an outer concentric circle 122, that is, adjacent to the boundary line between the display area 130 and the blurring area 120. The display pixel group 133 may include one or more display pixel units. Figure 3 The illustrated each display pixel group 133 may include a plurality of display sub-pixels, but the present invention is not limited thereto.

[0172] Similarly, a display pixel group 133 may include one or more display pixel units to form a unit. The number of display pixel units in one unit is the same as the number of sensor pixel group units in another unit. For example, Figure 4The illustration shows that the display pixel group 133 can include four display sub-pixels to correspond to the four sensor sub-pixels in the sensor pixel group 113, regardless of the color of the sensor sub-pixels. For example, the display pixel group 133 can include display sub-pixel 134, display sub-pixel 135, display sub-pixel 136, and display sub-pixel 137, but the present invention is not limited thereto.

[0173] If the sensor pixel group 113 includes n effective sensor pixels and m invalid sensor pixels, the display pixel brightness value DV of the display pixel unit can be determined to satisfy the following relationship: DV = [n / (n + m)] × (maximum pixel brightness value SV). The display pixel brightness value DV that satisfies the foregoing relationship in the display area 130 can ensure visual brightness consistency with respect to the sensor area 110. Therefore, the display pixel brightness value DV can represent a normal result or a normalized result.

[0174] In some embodiments of the present invention, the blurring pixel group 123 can be disposed in the blurring area 120. In other words, the blurring pixel group 123 can be disposed between the inner concentric circle 121 and the outer concentric circle 122, that is, between the sensor area 110 and the display area 130. A blurring pixel group 123 can include one or more blurring pixel units. Figure 3 The illustration shows that each blurring pixel group 123 can include a plurality of blurring sub-pixels, but the present invention is not limited thereto.

[0175] Similarly, a blurring pixel group 123 can include one or more blurring pixel units to form a unit. The number of blurring pixel units in one unit is the same as the number of sensor pixel units in another unit. For example, Figure 4 The illustration shows that the blurring pixel group 123 can include four blurring sub-pixels to correspond to the four sensor sub-pixels in the sensor pixel group 113, regardless of the color of the sensor sub-pixels. For example, a blurring pixel group 123 can include blurring sub-pixel 124, blurring sub-pixel 125, blurring sub-pixel 126, and blurring sub-pixel 127, but the present invention is not limited thereto.

[0176] In some embodiments of the present invention, there can be a straight line 102 passing through the sensor pixel group 113, the blurring pixel group 123, and the display pixel group 133. In some embodiments of the present invention, the straight line 102 can further pass through the center 111 of the inner concentric circle 121, the sensor pixel group 113, the blurring pixel group 123, and the display pixel group 133. Figure 3As shown in the figure, along the straight line 102, the minimum distance between a pixel group 133 and a sensor pixel group 113 is 1, the minimum distance between a blurred pixel group 123 and a sensor pixel group 113 is Z which is used as a weight value, and the minimum distance between a blurred pixel group 123 and a display pixel group 133 is (1 - Z), but the present invention is not limited thereto. When implementing the method of the present invention, the actual minimum distance between the display pixel group 133 and the sensor pixel group 113 is obtained according to the actual situation at the time of implementation and can be determined by those of ordinary skill in the art as long as this minimum distance is sufficient for implementing the present invention.

[0177] According to the display pixel brightness value DV and the sensor pixel brightness value SV, for example, the illumination of the brightness of each blurred pixel unit in the blurred area 120 can have a specific blurred pixel brightness value BV. The blurred pixel brightness value BV can represent the gamma level of the blurred pixels in the blurred pixel group 123, but the present invention is not limited thereto. For example, the blurred pixel brightness value BV is not greater than the maximum sensor pixel brightness value SV and not less than the corresponding display pixel brightness value DV to satisfy the linear weighting relationship based on Z, SV, and DV: BV = (1 - Z) × SV + Z × DV, but the present invention is not limited thereto.

[0178] Thus, a brightness gradient of pixel units can be formed along the straight line 102 from the sensor pixel group 113 to the display pixel group 133, so that the poor visual presentation feeling of a given image caused by the invalid display pixels in the sensor area 110 can be gradually weakened via the blurred area 120 and converge to the display area 130. In other words, the brightness gradient of pixel units can be used to make the obvious boundary line 11 of the under-screen camera area 10 as shown Figure 1 become blurred, so that the original boundary line 11 may become less obvious visually or even become substantially invisible.

[0179] A blurred pixel group 123 forming a unit is arranged in the blurred area 120 and is located between the sensor pixel group 113 and the display pixel group 133. Each pixel unit in a blurred pixel group 123 has a separate blurred pixel brightness value BV. The respective blurred pixel brightness values BV are calculated to align with the corresponding sensor pixel brightness values SV. A unit can include n + m sub-pixels regardless of the color of the sub-pixels, and the n + m sub-pixels can be arranged to form a pattern or be arranged orderly according to, for example, positions.

[0180] For example, one unit in the sensor pixel group 113 may include n effective sensor pixels and m ineffective sensor pixels, where n is an integer not less than 1, and m is an integer not less than 1. Therefore, one unit may correspondingly include n + m blurring pixels located in the blurring pixel group 123, and may correspondingly include n + m display pixels in the display area 130. Some of the blurring pixels in one unit may exclusively correspond to specific sensor pixels and specific display pixels. For example, the blurring pixels at the first position in one unit may correspond to the sensor pixels at the first position in another unit along the straight line 102 and correspond to the display pixels at the first position in another unit, and the blurring pixels at the second position in one unit may correspond to the sensor pixels at the second position in another unit along the straight line 102, and correspond to the display pixels at the second position in another unit, and so on.

[0181] After step 601, an adjusted image 103 with improved or further optimized visual presentation quality can thus be obtained. Figure 8 The figure shows according to Figure 1 An example of an image 103 with updated R / G / B information after the method of the present invention, which reduces the contour problem. As Figure 8 shown, compared with Figure 1 An image 103 showing better visual presentation quality can minimize the visual effect of black dots. For example, in the presence of an under-screen camera area, after performing the method of the present invention on the display panel 101, it can reduce Figure 8 The contour problem that occurs in the image 103 at the boundary line (basically invisible) between the sensor area (basically invisible), such as the under-screen camera area, and the display area 130, such as a general area.

[0182] The above are only the preferred embodiments of the present invention. All equivalent changes and modifications made according to the claims of the present invention shall fall within the scope of the present invention.
