[0056] Reference will now be made in detail to exemplary embodiments of the present disclosure, examples of which are illustrated in the accompanying drawings. Whenever possible, the same reference numerals are used in the drawings and the description to refer to the same or like parts.

[0057] Figure 1A It is a top view schematically showing a display device according to an embodiment of the present disclosure. Figure 1B for Figure 1A An enlarged schematic diagram of area A of a display device. Figure 1C for Figure 1A For the sake of clarity and convenience of description, Figure 1A Some elements of the display device are omitted from illustration.

[0058] Please refer to Figure 1A , the display device 100 has a display area 101 and a non-display area 102, wherein the display area 101 may include a screen area 101a and a sensing area 101b. In this embodiment, the sensing area 101b is located above the display area 101. For example, area A may be located in the screen area 101a, and area B may be located in the sensing area 101b. The size of the sensing area 101b may be set according to product requirements, but is not limited thereto. In some embodiments, the sensing area 101b may also be located at any position in the display area 101 (not shown).

[0059] In detail, in the present embodiment, the screen area 101a, for example, has high-resolution pixels and a smaller pixel size, and the sensing area 101b, for example, has low-resolution pixels and a larger pixel size, but is not limited thereto. In the present embodiment, since the sensing area 101b has a larger pixel size, the sensor 103 of the display device 100 is disposed in the sensing area 101b to reduce the diffraction effect caused by the metal wiring. In the present embodiment, the sensor 103 is, for example, face recognition under display (FRUD) that can be sensed by infrared rays, but is not limited thereto. In addition, although the shape of the sensor 103 of the present embodiment is shown as a quadrilateral, it is not limited thereto. In some embodiments, the shape of the sensor 103 may also be any polygon (not shown).

[0060] Please refer to Figure 1B and Figure 1C , Figure 1B For example, the image area 101a may be a pixel diagram with high-resolution pixels and a smaller pixel size. Figure 1C For example, the sensing area 101b may have a pixel schematic diagram with low resolution pixels and a larger pixel size. The display device 100 of this embodiment may include a substrate 104, scan lines SL, data lines DL, a pixel matrix 110, and a black matrix layer (black matrix, BM) 120. The substrate 104 may include a rigid substrate, a flexible substrate, or a combination thereof. For example, the material of the substrate 104 may include glass, quartz, sapphire (sapphire), ceramic, polycarbonate (PC), polyimide (PI), polyethyleneterephthalate (PET), other suitable substrate materials, or a combination thereof, but not limited thereto.

[0061] In this embodiment, the scan line SL, the data line DL and the drain electrode SD2 are disposed on the substrate 104. The scan line SL extends along the direction X, the read line DL extends along the direction Y, and the normal direction of the substrate 104 is the direction Z, wherein the directions X, Y and Z are different from each other and are perpendicular to each other.

[0062] In the present embodiment, the pixel matrix 110 may be defined by a plurality of scan lines SL and a plurality of data lines DL, and the pixel matrix 110 includes a plurality of sub-pixels. In the present embodiment, the pixel matrix 110 may include a first sub-pixel 111 and a second sub-pixel 112. For example, the four boundaries of each sub-pixel may be formed by two adjacent scan lines SL and two adjacent data lines DL, and the area (or pixel size) of each sub-pixel may be regarded as the area (or size) of the region surrounded by the two adjacent scan lines SL and the two adjacent data lines DL. In the present embodiment, adjacent means that there are no other identical elements between two identical elements. Wherein, please refer to Figure 1B , the first sub-pixel 111 is located in the screen area 101a with a smaller pixel size and has an area A1. Figure 1C , the second sub-pixel 112 is located in the sensing area 101b with a larger pixel size, and has another area A2. The area A1 of the first sub-pixel 111 is different from the area A2 of the second sub-pixel 112. In the present embodiment, the area A1 of the first sub-pixel 111 is, for example, smaller than the area A2 of the second sub-pixel 112, and the pixel size of the first sub-pixel 111 is, for example, smaller than the pixel size of the second sub-pixel 112, but is not limited thereto. In the present embodiment, the area A1 of the first sub-pixel 111 is, for example, the product of the length L1 of the first sub-pixel 111 along the direction Y and the length L2 of the first sub-pixel 111 along the direction X, and the area A2 of the second sub-pixel 112 is, for example, the product of the length L3 of the second sub-pixel 112 along the direction Y and the length L4 of the second sub-pixel 112 along the direction X. For details, please refer to Figure 1B , the length L1 of the first sub-pixel 111 along the direction Y is the minimum distance between the boundary SL-R of the scan line SL and the boundary SL-R' of another scan line SL, and the length L2 of the first sub-pixel 111 along the direction X is the minimum distance between the boundary DL-R of the data line DL and the boundary DL-R' of another data line DL, but not limited thereto. Among them, the scan line SL also has another boundary SL-L opposite to its boundary SL-R, another scan line SL also has another boundary SL-L' opposite to its boundary SL-R', the data line DL also has another boundary DL-L opposite to its boundary DL-R, and another data line DL also has another boundary DL-L' opposite to its boundary DL-R'.

[0063] In the present embodiment, the black matrix layer 120 is disposed on the substrate 104 and disposed on the scan line SL and the data line DL. The black matrix layer 120 overlaps with the scan line SL in the direction Z (the normal direction of the substrate 104), and the black matrix layer 120 overlaps with the data line DL in the direction Z (the normal direction of the substrate 104). In the present embodiment, the black matrix layer 120 partially overlaps with the first sub-pixel 111 in the direction Z (the normal direction of the substrate 104) to form an overlapping region R1, and the overlapping region R1 has a shielding area AR1. The black matrix layer 120 may also partially overlap with the second sub-pixel 112 in the direction Z (the normal direction of the substrate 104) to form another overlapping region R2, and the overlapping region R2 has a shielding area AR2. Next, since the value of the shielding area AR1 of the overlapping region R1 divided by the area A1 of the first sub-pixel 111 can be approximately equal to the value of the shielding area AR2 of the other overlapping region R2 divided by the area A2 of the second sub-pixel 112, the display device 100 of this embodiment can avoid the problem of display brightness difference or image abnormality caused by the difference in aperture ratio between the second sub-pixel 112 with a large pixel size and the first sub-pixel 111 with a small pixel size. In other words, the ratio of the shielding area AR1 of the black matrix layer 120 in the first sub-pixel 111 to the area A1 of the first sub-pixel 111 can be equal to the ratio of the shielding area AR2 of the black matrix layer 120 in the second sub-pixel 112 to the area A2 of the second sub-pixel 112, and the ratio of the unshielded area of ​​the black matrix layer 120 in the first sub-pixel 111 to the area A1 of the first sub-pixel 111 can also be equal to the ratio of the unshielded area of ​​the black matrix layer 120 in the second sub-pixel 112 to the area A2 of the second sub-pixel 112. That is, the ratio of the opening area exposed by the black matrix layer 120 in the first sub-pixel 111 to the area A1 of the first sub-pixel 111 (i.e., the aperture ratio, AR) can be equal to the ratio of the opening area exposed by the black matrix layer 120 in the second sub-pixel 112 to the area A2 of the second sub-pixel 112. In this way, the display device 100 of this embodiment can have a consistent pixel brightness or improve the display quality. In detail, the method disclosed in this disclosure can reduce the user's perception of the brightness difference of the display area 101 of the display device 100. In this embodiment, "equal" can be defined as when the difference between the two is less than 5%, the two can be regarded as equal.

[0064] Specifically, the black matrix layer 120 includes longitudinal black matrix layers 121 and 122 and transverse black matrix layers 123 and 124, wherein the longitudinal black matrix layers 121 and 122 extend along a direction X, and the transverse black matrix layers 123 and 124 extend along a direction Y. The longitudinal black matrix layers 121 and 122 may overlap or shield the data lines DL, and the transverse black matrix layers 123 and 124 may overlap or shield the scan lines SL. In the present embodiment, the width W1 of the longitudinal black matrix layer 121 may be the same as or different from the width W2 of the longitudinal black matrix layer 122, and the width W3 of the transverse black matrix layer 123 may be the same as or different from the width W4 of the transverse black matrix layer 124, so that the longitudinal black matrix layer 121 and the transverse black matrix layer 123 may partially overlap the first sub-pixel 111 to form an overlapping region R1 in the first sub-pixel 111, and the longitudinal black matrix layer 122 and the transverse black matrix layer 124 may partially overlap the second sub-pixel 112 to form an overlapping region R2 in the second sub-pixel 112, wherein the ratio of the shielding area AR1 of the overlapping region R1 to the area A1 of the first sub-pixel 111 may be equal to the ratio of the shielding area AR2 of the overlapping region R2 to the area A2 of the second sub-pixel 112. That is, the aperture ratio of the first sub-pixel 111 may be equal to the aperture ratio of the second sub-pixel 112. In the present embodiment, the widths W1 and W2 are measured, for example, along the direction X, and the widths W3 and W4 are measured, for example, along the direction Y. Therefore, the area of ​​the first sub-pixel 111 that is not overlapped by the black matrix layer 120 is the first sub-pixel opening area O1, that is, the area surrounded by the edge of the longitudinal black matrix layer 121 and the edge of the transverse black matrix layer 123 is the first sub-pixel opening area O1, and the first sub-pixel opening area O1 has a first sub-pixel opening area A1', and the area surrounded by the edge of the longitudinal black matrix layer 122 and the edge of the transverse black matrix layer 124 is the second sub-pixel opening area O2, and the second sub-pixel opening area O2 has a second sub-pixel opening area A2'. In the present disclosure, the shielding area AR1 of the overlapping area R1 is obtained by deducting the first sub-pixel opening area A1' from the first pixel sub-area A1. Please refer to Figure 1B , when the pixel area A1 of the first sub-pixel 111 is the product of the length L1 of the first sub-pixel 111 along the direction Y and the length L2 of the first sub-pixel 111 along the direction X, and the first sub-pixel opening area A1' is the product of the length L1' of the first sub-pixel opening area O1 along the direction Y and the length L2' of the first sub-pixel opening area O1 along the direction X, wherein the length L1' is the length L1 of the first sub-pixel 111 along the direction Y minus the width W3 of the horizontal black matrix layer 123 along the direction Y, and the length L2' is the length L2 of the first sub-pixel 111 along the direction X minus the width W1 of the vertical black matrix layer 121 along the direction X. The above-mentioned calculation method of the pixel area and the opening area is only for illustration and is not limited to this embodiment method.

[0065] More specifically, in the present embodiment, although the pixel size of the second sub-pixel 112 is larger than the pixel size of the first sub-pixel 111, the width W2 of the longitudinal black matrix layer 122 in the second sub-pixel 112 can be made larger than the width W1 of the longitudinal black matrix layer 121 in the first sub-pixel 111, so that the shielding area AR2 of the longitudinal black matrix layer 122 in the second sub-pixel 112 can be larger than the shielding area AR1 of the longitudinal black matrix layer 121 in the first sub-pixel 111, thereby making the aperture ratio of the second sub-pixel 112 equal to the aperture ratio of the first sub-pixel 111.

[0066] For example, when the resolution of the screen area 101a is 403 ppi (pixels per inch) and the resolution of the sensing area 101b is 134 ppi, the pixel size of the first sub-pixel 111 in the screen area 101a is 21±5 μm×63±5 μm (length L1 along direction Y×length L2 along direction X), and the pixel size of the second sub-pixel 112 in the sensing area 101b is 63±5 μm×189±5 μm (length L3 along direction Y×length L4 along direction X). At this time, when the width W1 of the longitudinal black matrix layer 121 in the first sub-pixel 111 along direction X is 16.85±5 μm, and the width W3 of the transverse black matrix layer 123 along direction Y is 5±5 μm, the aperture ratio of the first sub-pixel 111 is 55.81%. Therefore, in order to make the aperture ratio of the second sub-pixel 112 equal to the aperture ratio of the first sub-pixel 111, the width W2 of the longitudinal black matrix layer 122 in the second sub-pixel 112 along the direction X is increased to 74.4±5μm in this embodiment, and the width W4 of the transverse black matrix layer 124 in the second sub-pixel 112 along the direction Y is maintained at 5±5μm, so that the aperture ratio of the second sub-pixel 112 can be 55.82%. The aperture ratio design can be modified according to product requirements, and the present disclosure is not limited thereto. Through the method provided by the present disclosure, the pixel aperture ratio can be made consistent, and then the pixel brightness can be made consistent, thereby improving the display quality.

[0067] In addition, in the present embodiment, since the material of the black matrix layer 120 may include a material that is permeable to infrared rays, the longitudinal black matrix layer 122 and the transverse black matrix layer 124 in the second sub-pixel 112 will not affect the penetration of infrared rays. That is, the arrangement of the longitudinal black matrix layer 122 and the transverse black matrix layer 124 will not affect the sensor 103 sensing by infrared rays. Therefore, the ratio of the area outside the metal traces (such as the scan line SL and the data line DL, but not limited thereto) in the second sub-pixel 112 to the area A2 of the second sub-pixel 112 can be regarded as the infrared aperture ratio. In the present embodiment, the infrared aperture ratio of the second sub-pixel 112 can be 91.1%. In addition, in the present embodiment, the above-mentioned infrared permeable material method can be to reduce the carbon content in the black matrix layer or use black pigment or other color mixed pigments, but not limited thereto.

[0068] In this embodiment, although the aperture ratio of the second sub-pixel 112 can be equal to the aperture ratio of the first sub-pixel 111 by increasing the width W2 of the longitudinal black matrix layer 122 in the second sub-pixel 112 along the direction X, the invention is not limited thereto. In some embodiments, the width of the transverse black matrix layer in the second sub-pixel can also be increased (e.g. Figure 4-Figure 6 ), or by simultaneously increasing the width of the longitudinal black matrix layer and the width of the transverse black matrix layer in the second sub-pixel (as shown in Figure 7 As shown) the aperture ratio of the second sub-pixel can be equal to the aperture ratio of the first sub-pixel.

[0069] In addition, in this embodiment, although the longitudinal black matrix layer 122 and the transverse black matrix layer 124 in the second sub-pixel 112 are both one line, the present disclosure does not limit the number of the longitudinal black matrix layer 122 and the transverse black matrix layer 124 in the second sub-pixel 112. Therefore, in some embodiments, the number of the longitudinal black matrix layer 122 and the transverse black matrix layer 124 in the second sub-pixel 112 can be increased. Figure 2-Figure 3 ), increasing the number of lateral black matrix layers in the second sub-pixel (as shown Figure 5-Figure 6 ), or simultaneously increase the number of the longitudinal black matrix layer and the transverse black matrix layer in the second sub-pixel (as shown in Figure 8 As shown) the aperture ratio of the second sub-pixel can be equal to the aperture ratio of the first sub-pixel.

[0070] In short, in the display device 100 of the present disclosed embodiment, by making the value of the shielding area AR1 of the overlapping region R1 where the black matrix layer 120 partially overlaps the first sub-pixel 111 divided by the area A1 of the first sub-pixel 111 equal to the value of the shielding area AR2 of the overlapping region R2 where the black matrix layer 120 partially overlaps the second sub-pixel 112 divided by the area A2 of the second sub-pixel 112, the problem of display brightness difference or picture abnormality caused by the difference in aperture ratio between the second sub-pixel 112 with a large pixel size and the first sub-pixel 111 with a small pixel size is avoided, so that the display device 100 of the present embodiment can have the effect of consistent pixel brightness or improved display quality.

[0071] Other embodiments will be listed below for illustration. It must be noted that the following embodiments use the component numbers and some contents of the previous embodiments, wherein the same numbers are used to represent the same or similar components, and the description of the same technical contents is omitted. The description of the omitted parts can be referred to the previous embodiments, and the following embodiments will not be repeated.

[0072] Figure 2 This is a top view schematic diagram of a display device according to another embodiment of the present disclosure. Figure 1C and Figure 2 The display device 100a of this embodiment is substantially similar to Figure 1C The display device 100a of the present embodiment is different from the display device 100a in that, in the top view of the display device 100a of the present embodiment, in the second sub-pixel 112a, the vertical black matrix layer 122a includes a plurality of vertical branches 122a1 and 122a2.

[0073] Specifically, please refer to Figure 2 In this embodiment, Figure 1C The longitudinal black matrix layer 122 is evenly divided into longitudinal branches 122a1 and longitudinal branches 122a2, so that the width W2a of the longitudinal branches 122a1 and the longitudinal branches 122a2 along the direction X is approximately Figure 1C The width of the longitudinal black matrix layer 122 along the direction X is half of the width W2 to reduce visibility. The sum of the widths of the plurality of longitudinal branches 122a1 and 122a2 of the longitudinal black matrix layer 122a in the second sub-pixel 112a of this embodiment is also greater than that in Figure 1B The sum of the widths of the longitudinal black matrix layer 121 along the direction X in the first sub-pixel 111 .

[0085] Figure 7 This is a top view of a display device according to another embodiment of the present disclosure. Figure 1C and Figure 7 The display device 100f of this embodiment is substantially similar to Figure 1C The display device 100 of the present embodiment is different from the display device 100 mainly in that, in the top view of the display device 100f of the present embodiment, the width W4f of the horizontal black matrix layer 124f of the second sub-pixel 112f along the direction Y is increased, and the width W2f of the vertical black matrix layer 122f along the direction X is reduced to still greater than Figure 1B The longitudinal width W1 of the black matrix layer 121 along the direction X.

[0086] Specifically, please refer to Figure 7 In this embodiment, by making the width W4f of the horizontal black matrix layer 124f in the second sub-pixel 112f along the direction Y and the width W2f of the vertical black matrix layer 122f along the direction X both greater than Figure 1B By reducing the width W3 of the horizontal black matrix layer 123 in the first sub-pixel 111 along the direction Y and the width W1 of the vertical black matrix layer 121 along the direction X, the shielding area of ​​the horizontal black matrix layer 124f in the second sub-pixel 112f can be larger than Figure 1B The shielding area of ​​the horizontal black matrix layer 123 in the first sub-pixel 111 is made larger than that of the vertical black matrix layer 122f in the second sub-pixel 112f.

In addition, in this embodiment, the infrared aperture ratio of the second sub-pixel 112f can also be 91.1%.

[0088] Figure 8 This is a top view of a display device according to another embodiment of the present disclosure. Figure 7 and Figure 8 The display device 100g of this embodiment is substantially similar to Figure 7 The display device 100f of the present embodiment is a display device 100g, so the same and similar components of the two embodiments are not repeated here. The display device 100g of the present embodiment is different from the display device 100f mainly in that, in the top view of the display device 100g of the present embodiment, in the second sub-pixel 112g, the horizontal black matrix layer 124g includes a plurality of horizontal branches 124g1, 124g2, 124g3, and the vertical black matrix layer 122g includes a plurality of vertical branches 122g1, 122g2, 122g3.

[0089] Specifically, please refer to Figure 8 In this embodiment, Figure 7 The horizontal black matrix layer 124f is evenly divided into a horizontal branch 124g1, a horizontal branch 124g2 and a horizontal branch 124g3, and Figure 7 The vertical black matrix layer 122f is evenly divided into vertical branches 122g1, 122g2 and 122g3 to reduce visibility. The width W4g of the horizontal branches 124g1, 124g2 and 124g3 along the direction Y is approximately Figure 7The width W4f of the horizontal black matrix layer 124f along the direction Y is one third of the width W4f of the horizontal black matrix layer 124f, and the width W2g of the vertical branches 122g1, 122g2 and 122g3 along the direction X is approximately Figure 7 The longitudinal width W2f of the black matrix layer 122f along the direction X is one third of the width W2f.

[0090] For example, when Figure 1B The width W3 of the transverse black matrix layer 123 in the first sub-pixel 111 along the direction Y is 5±5 μm and the width W1 of the longitudinal black matrix layer 121 along the direction X is 16.85±5 μm, and Figure 7 In the embodiment of the present invention, when the width W4f of the transverse black matrix layer 124f of the second sub-pixel 112f along the direction Y is 15±5μm and the width W2f of the longitudinal black matrix layer 122f along the direction X is 50.55±5μm, the width W4g of the plurality of transverse branches 124g1, 124g2, 124g3 of the transverse black matrix layer 124g of the second sub-pixel 112g along the direction Y is approximately 5±5μm and the width W2g of the plurality of longitudinal branches 122g1, 122g2, 122g3 of the longitudinal black matrix layer 122g along the direction X is approximately 16.85±5μm, so that the sum of the widths (15±5μm) of the transverse branches 124g1, 124g2 and 124g3 along the direction Y in the second sub-pixel 112g is greater than that in the embodiment of the present invention. Figure 1B The sum of the widths of the horizontal black matrix layer 124 in the first sub-pixel 111 along the direction Y (5±5 μm) is made greater than the sum of the widths of the longitudinal branches 122g1, 122g2 and 122g3 in the second sub-pixel 112g along the direction X (50.55±5 μm). Figure 1B The sum of the widths of the vertical black matrix layer 121 in the first sub-pixel 111 along the direction X is (16.85±5 μm). Thus, the aperture ratio of the second sub-pixel 112g of this embodiment can be 55.81%, which is equal to Figure 1B The aperture ratio of the first sub-pixel 111 is 91.1%. In this embodiment, the infrared aperture ratio of the second sub-pixel 112g can also be 91.1%. The resolution (pixels per inch) referred to in the present disclosure can be calculated by the following relationship:

[0091] PPI = √(w^2+h^2) / d (Formula I)

[0092] Wherein, w is the horizontal resolution of the display device screen, h is the vertical resolution of the display device screen, and d is the diagonal length of the display device screen, and the length unit is inches. Then, the pixel size L2 (unit: m) of this case can be obtained by using the following relationship:

[0093] L2=2.54 / PPI×10000 (Relationship II)

[0094] In the display device disclosed herein, the pixel size L2 is, for example, three times of L1, but is not limited thereto. The pixel size design can be changed according to the requirements of the display device.

[0095] In summary, in the display device of the present disclosed embodiment, by making the value of the shielding area of ​​the overlapping region where the black matrix layer partially overlaps with the first sub-pixel divided by the area of ​​the first sub-pixel equal to the value of the shielding area of ​​the overlapping region where the black matrix layer partially overlaps with the second sub-pixel divided by the area of ​​the second sub-pixel, the problem of display brightness difference or picture abnormality caused by the difference in aperture ratio between the second sub-pixel with a large pixel size and the first sub-pixel with a small pixel size can be avoided, thereby making the display device of the present embodiment have the effect of consistent pixel brightness or improved display quality.
