Description

Technical Field

[0002] Capacitive touchscreen technology has revolutionized smartphones and tablets, and is widely used in laptops, desktop monitors, and all-in-one computers. To turn a display into a "touchpad," it's necessary to combine the two distinct functions of display and touch. In the past, touch sensors were integrated into the display through a "layering" process. Recent technology has led to embedded displays that directly integrate the touch sensor into the display. However, touch signal lines located on the pixel array layer can cause problems such as color difference, light leakage in dark conditions, and reduced contrast at different viewing angles. Summary of the Invention

[0039] Reference Figure 1A , Figure 1B as well as Figure 1C The display panel 10 includes a first substrate 100, a pixel array layer PL, a second substrate 200, and a color resist layer 300. The first substrate 100 has a first surface S1. The second substrate 200 has a second surface S2. The pixel array layer PL is disposed on the first surface S1 and includes a plurality of gate lines and a plurality of data lines of a TFT array, as well as a plurality of signal lines TS1, TS2…TSm ,TS m+1 …It should be specifically noted that these signal lines TS1, TS2…TS m ,TS m+1 …These are not the gate lines and data lines of the TFT array. Furthermore, for ease of understanding, these gate lines and data lines of the TFT array are not shown.

[0040] A color resist layer 300 is disposed on the second surface S2 and located above the pixel array layer PL. The display panel 10 can be implemented as an embedded touch panel, with signal lines TS1, TS2…TS m ,TS m+1 …These are touch signal lines, connected between multiple touch sensors SR and controller DR. However, the present invention is not limited thereto; in some embodiments, the display panel 10 is not a touch panel, and the signal lines TS1, TS2…TS… m ,TS m+1 …can be a heating wire used for heating.

[0041] The color resist layer 300 includes a plurality of pixel units PX. These pixel units PX are arranged sequentially along the X direction, and each pixel unit PX includes a first color resist CR1, a second color resist CR2, and a third color resist CR3 arranged sequentially along the X direction, wherein the first color resist CR1, the second color resist CR2, and the third color resist CR3 are of different colors. In this embodiment, the colors of the first color resist CR1, the second color resist CR2, and the third color resist CR3 are red, green, and blue, respectively, but this is not a limitation. In some embodiments, the colors of the first color resist CR1, the second color resist CR2, and the third color resist CR3 are green, blue, and red, respectively. In some embodiments, the colors of the first color resist CR1, the second color resist CR2, and the third color resist CR3 are blue, red, and green, respectively.

[0042] like Figure 1B As shown, each signal line TS1, TS2…TS m ,TS m+1 …Due to limitations in the metal etching manufacturing process, it has a taper. Under these conditions, when ambient light (EL) (white light) is incident on the display panel 10, it will be transmitted through the signal lines TS1, TS2…TS… m ,TS m+1 …After being reflected from the side, light is emitted from the display panel 10 and formed into light of the color that it passes through the color barrier.

[0043] exist Figure 1A , Figure 1B as well as Figure 1C In the embodiment, each signal line TS1, TS2…TS m ,TS m+1…The example is positioned below the black matrix BM at the junction of the first color resistor CR1 and the second color resistor CR2. Signal lines TS1, TS2…TS are not configured below the black matrix BM. m ,TS m+1 …spacers can be configured at these locations, but are not limited to them. Therefore, as Figure 1B As shown, when a user views the display panel 10 from a side angle from the +X direction towards the -X direction, each signal line TS1, TS2…TS m ,TS m+1 …The side facing the +X direction reflects ambient light EL, and the user will see reflected light GR with the color of the second color filter CR2, such as green reflected light GR. Similarly, when the user views the display panel 10 from the -X direction towards the +X direction at a side angle, each signal line TS1, TS2…TS m ,TS m+1 …The side facing the -X direction reflects ambient light EL, and you will see reflected light RR of the color with the first color resist CR1, such as red reflected light RR. These colored reflected lights may cause color difference in the display panel 10 at side viewing angles.

[0044] To fully illustrate the various embodiments of the present invention, other embodiments will be described below. It must be noted that the following embodiments differ from the foregoing embodiments in the configuration of the signal lines, and descriptions of identical technical content are omitted. For explanations of the omitted parts, please refer to the foregoing embodiments. Furthermore, the following embodiments also use the component reference numerals and some content from the foregoing embodiments, employing the same reference numerals to represent the same or similar components.

[0045] Reference Figure 1A as well as Figure 2 In another embodiment of the present invention, the signal lines TS1, TS2…TS of the display panel 10 m ,TS m+1 …these signal lines are sequentially arranged along the X direction below the black matrix BM at the junction of adjacent color resists CR1, CR2, CR3. In this configuration, when a user views the display panel 10 from a side angle from the +X direction towards the -X direction, these signal lines TS1, TS2…TS… m ,TS m+1…The sides facing the +X direction will produce reflected light of colors with the first color resist CR1, the second color resist CR2, the third color resist CR3, and so on, for example, red reflected light, green reflected light, blue reflected light, red reflected light, green reflected light, blue reflected light… Therefore, the above-mentioned colored light will mix to form white reflected light. Similarly, when a user views the display panel 10 from the -X direction towards the +X direction at a side angle, white reflected light will also be seen. It should be noted that, compared to… Figure 1C The display panel shown in this embodiment will not exhibit color difference at side viewing angles due to reflections from the signal lines.

[0046] Reference Figure 1A as well as Figure 3 In a first embodiment of the present invention, the display panel 10 includes a first region R1, a second region R2, and a third region R3 arranged sequentially along the X direction. Each of the first region R1, the second region R2, and the third region R3 has M pixel units along the X direction. Specifically, the first region R1 has pixel units PX1, PX2, PX3…PX along the X direction. M The second region R2 has pixel units PX along the X direction. M+1 PX M+2 PX M+3 …PX 2M The third region R3 has pixel units PX along the X direction. 2M+1 PX 2M+2 PX 2M+3 …PX 3M M is a positive integer.

[0047] The display panel 10 also includes N first signal lines TP1, TP2, TP3…TP N N second signal lines TP N+1 ,TP N+2 , TP N+3 …TP 2N And N third signal lines TP 2N+1 , TP 2N+2 , TP 2N+3 …TP 3N Each of the first signal lines TP1, TP2, TP3…TP N The second signal line TP is configured within the first region R1, and below the boundary between the first color resists CR1 and the second color resists CR2 within the first region R1. N+1 , TP N+2 , TP N+3 …TP 2NThe third color resists CR3 and the first color resists CR1 are configured within the second region R2, and below the boundary between them. Each third signal line TP 2N+1 , TP 2N+2 , TP 2N+3 …TP 3N The second color resistors CR2 and the third color resistors CR3 are configured within the third region R3, and below the boundary between them. N is a positive integer, and N is less than or equal to M.

[0048] In some embodiments, N equals M. That is, a first signal line TP1, TP2, TP3…TP is disposed below the boundary between each first color resist CR1 and second color resist CR2 within the first region R1. N In one of the regions, R2, a second signal line TP is provided at the junction of each third color resistor CR3 and the first color resistor CR1. N+1 , TP N+2 , TP N+3 …TP 2N One of them, and a third signal line TP is provided at the junction of each second color resistor CR2 and the third color resistor CR3 within the third region R3. 2N+1 , TP 2N+2 , TP 2N+3 …TP 3N one of the.

[0049] Accordingly, when a user views the display panel 10 from a side angle from the +X direction towards the -X direction, the first signal lines TP1, TP2, TP3…TP N The sides facing the +X direction will each produce reflected light of the color of the second color resist CR2, for example, green reflected light; these second signal lines TP N+1 , TP N+2 , TP N+3 …TP 2N The sides facing the +X direction will each generate reflected light of the color of the first color resist CR1, for example, red reflected light; these third signal lines TP 2N+1 , TP 2N+2 ,TP 2N+3 …TP 3N The sides facing the +X direction will each produce reflected light of the color of the third color block CR3, such as blue reflected light.

[0050] Similarly, when a user views the display panel 10 from a side angle from the -X direction towards the +X direction, these first signal lines TP1, TP2, TP3…TP NThe sides facing the -X direction will each generate reflected light of the color of the first color filter CR1, for example, red reflected light; these second signal lines TP N+1 , TP N+2 , TP N+3 …TP 2N The sides facing the -X direction will each produce reflected light of the color of the third color resist CR3, for example, blue reflected light; these third signal lines TP 2N+1 , TP 2N+2 ,TP 2N+3 …TP 3N The sides facing the -X direction will each produce reflected light of the color with the second color stop CR2, such as green reflected light.

[0051] In some preferred embodiments, N equals M and is less than or equal to 30. When a user views the display panel 10 from a side angle from the +X direction towards the -X direction, the green reflected light from the first region R1, the red reflected light from the second region R2, and the blue reflected light from the third region R3 mix to form white light. Similarly, when a user views the display panel 10 from a side angle from the -X direction towards the +X direction, the red reflected light from the first region R1, the blue reflected light from the second region R2, and the green reflected light from the third region R3 mix to form white light. Therefore, compared to Figure 1C The display panel shown in this embodiment will not exhibit color difference at side viewing angles due to reflections from the signal lines.

[0052] It should also be noted that the first region R1 of the display panel 10 in this embodiment does not contain the second signal line TP. N+1 ,TP N+2 , TP N+3 …TP 2N and the third signal line TP 2N+1 , TP 2N+2 , TP 2N+3 …TP 3N The first signal lines TP1, TP2, TP3…TP are not present in the second region R2. N and the third signal line TP 2N+1 , TP 2N+2 , TP 2N+3 …TP 3N The third region R3 does not contain the first signal lines TP1, TP2, TP3…TP N and the second signal line TP N+1 , TP N+2 , TP N+3 …TP 2N Compared to Figure 2In the illustrated embodiment, signal lines TS1, TS2…TS are arranged below the black matrix BM at the junction of adjacent color resists CR1, CR2, CR3. m ,TS m+1 …the situation, Figure 3 The signal lines TP1…TP in the illustrated embodiment N , TP N+1 …TP 2N , TP 2N+1 …TP 3N The signal line density is reduced to one-third. This avoids issues such as dark-state light leakage and decreased contrast at the front / side viewing angles caused by excessively high signal line density. In some embodiments, Figure 3 The center (normal viewing angle) contrast of the display panel in the middle is relatively high. Figure 2 The center contrast of the display panel has been improved by 8%.

[0053] In some preferred embodiments, N equals M and is less than or equal to 25. In some even preferred embodiments, N equals M and is less than or equal to 20.

[0054] In some embodiments, N can be less than M. For example, M=20, N=10, and the first signal lines TP1, TP2, TP3…TP are adjacent to each other. N The spacing between them is the same, and the second signal lines TP are adjacent to each other. N+1 , TP N+2 , TP N+3 …TP 2N The spacing between them is the same, and the third signal lines TP are adjacent to each other. 2N+1 , TP 2N+2 , TP 2N+3 …TP 3N The spacing between them is the same. This allows for maintaining no chromatic aberration from a lateral viewing angle and further reduces the distribution density of the signal lines.

[0055] Reference Figure 1A as well as Figure 4 In a second embodiment of the present invention, the display panel 10 includes a plurality of pixel units PX arranged along the X and Y directions, and each pixel unit PX includes a first color resist CR1, a second color resist CR2 and a third color resist CR3 arranged sequentially along the X direction, wherein the first color resist CR1, the second color resist CR2 and the third color resist CR3 are different colors.

[0056] The display panel 10 also includes multiple signal lines TP. i Each signal line TP iThe Y-direction includes multiple first line segments SE1, multiple second line segments SE2, and multiple third line segments SE3. A fourth line segment SE4 exists between the first line segments SE1 and the second line segments SE2, and a fifth line segment SE5 exists between the second line segments SE2 and the third line segments SE3. The fourth line segment SE4 is parallel to the fifth line segment SE5.

[0057] Each first segment SE1 corresponds to the intersection of N first color resistors CR1 and N second color resistors CR2; each second segment SE2 corresponds to the intersection of N second color resistors CR2 and N third color resistors CR3; and each third segment SE3 corresponds to the intersection of N third color resistors CR3 and N first color resistors CR1, where N is a positive integer. Since a first color resistor CR1, a second color resistor CR2, and a third color resistor CR3 have the same width in the Y direction, each first segment SE1, a second segment SE2, and a third segment SE3 will have the same length in the Y direction. Furthermore, each signal line TP... i It has a symmetrical structure relative to the virtual line C1, such as Figure 4 As shown.

[0058] Accordingly, when a user views the display panel 10 from a side angle from the +X direction toward the -X direction, the side of the first line segment SE1 facing the +X direction will produce reflected light of the color of the second color resist CR2, for example, green reflected light; the side of the second line segment SE2 facing the +X direction will produce reflected light of the color of the third color resist CR3, for example, blue reflected light; and the side of the third line segment SE3 facing the +X direction will produce reflected light of the color of the first color resist CR1, for example, red reflected light.

[0059] Similarly, when a user views the display panel 10 from a side angle from the -X direction toward the +X direction, the side of the first line segment SE1 facing the -X direction will produce reflected light of the color of the first color resist CR1, for example, red reflected light; the side of the second line segment SE2 facing the -X direction will produce reflected light of the color of the second color resist CR2, for example, green reflected light; and the side of the third line segment SE3 facing the -X direction will produce reflected light of the color of the third color resist CR3, for example, blue reflected light.

[0060] In some preferred embodiments, N is less than or equal to 25. In some even preferred embodiments, N is less than or equal to 20. Accordingly, when a user views the display panel 10 from a side angle from the +X direction toward the -X direction, the green reflected light from the first line segment SE1, the blue reflected light from the second line segment SE2, and the red reflected light from the third line segment SE3 will mix to form white light. Similarly, when a user views the display panel 10 from a side angle from the -X direction toward the +X direction, the red reflected light from the first line segment SE1, the green reflected light from the second line segment SE2, and the blue reflected light from the third line segment SE3 will mix to form white light. Therefore, compared to Figure 1C The display panel shown in this embodiment will not exhibit color difference at side viewing angles due to reflections from the signal lines.

[0061] Furthermore, compared to Figure 2 Intermediate signal lines TS1, TS2…TS m ,TS m+1 …distribution density, Figure 4 TP signal line i The lower distribution density avoids problems such as light leakage in dark states and decreased contrast at the front / side viewing angles caused by excessively high signal line distribution density.

[0062] Similarly, refer to Figure 4 Each signal line TP i It also includes multiple dummy segments (DL), and each signal line (TP) i Electrical signals on Figure 4 As shown by the arrows, these dumb lines DL have no electrical signal. Since the fourth line SE4 is positioned between two adjacent second color resistors CR2, and the fifth line SE5 is positioned between two adjacent third color resistors CR3, by positioning these dumb lines DL between two adjacent first color resistors CR1, no color difference occurs when the user views the display panel 10 from the +Y direction towards the -Y direction or from the -Y direction towards the +Y direction.

[0063] Reference Figure 1A as well as Figure 5 In a third embodiment of the present invention, the display panel 10 includes a plurality of first signal lines TP1 and a plurality of second signal lines TP2. The color resist layer 300 includes a plurality of first color resists CR1, a plurality of second color resists CR2, and a plurality of third color resists CR3, wherein the first color resists CR1, second color resists CR2, and third color resists CR3 are of different colors. Each first signal line TP1 corresponds to the boundary between two adjacent third color resists CR3, and each second signal line TP2 corresponds to the boundary between two adjacent first color resists CR1. The first signal lines TP1 and the second signal lines TP2 are arranged alternately along the X direction, as shown below. Figure 5 As shown. Furthermore, in the X direction, the area between adjacent first signal lines TP1 and second signal lines TP2 corresponds to multiple second color resists CR2. Accordingly, when a user views the display panel 10 from a side viewpoint from the +X direction towards the -X direction or from the -X direction towards the +X direction, the sides of the first signal lines TP1 will respectively generate reflected light of the color of the third color resist CR3, for example, blue reflected light; the sides of the second signal lines TP2 will respectively generate reflected light of the color of the first color resist CR1, for example, red reflected light. The blue reflected light from the first signal line TP1 and the red reflected light from the second signal line TP2 will mix to form purple light.

[0064] In this embodiment, a first color resist CR1, a second color resist CR2, a third color resist CR3, a third color resist CR3, a second color resist CR2, and a first color resist CR1 are arranged sequentially in the X direction, and the above arrangement is repeated periodically in the X direction. Accordingly, the distance between any two adjacent first signal lines TP1 and second signal lines TP2 is a constant. Therefore, when a user views the display panel 10 from a side view, the purple reflected light will be uniformly distributed.

[0065] Reference Figure 1A as well as Figure 6In the fourth embodiment of the present invention, the display panel 10 includes a plurality of first signal lines TP1, a plurality of second signal lines TP2, and a plurality of third signal lines TP3. The color resist layer 300 includes a first color resist CR1, a plurality of second color resists CR2, and a plurality of third color resists CR3, wherein the first color resist CR1, second color resist CR2, and third color resist CR3 are of different colors. Each first signal line TP1 corresponds to the boundary between two adjacent third color resists CR3, each second signal line TP2 corresponds to the boundary between two adjacent second color resists CR2, and each third signal line TP3 corresponds to the boundary between two adjacent first color resists CR1. The first signal lines TP1, second signal lines TP2, and third signal lines TP3 are arranged sequentially along the X direction, and the arrangement is repeated periodically along the X direction. In the X direction, the area between adjacent first signal lines TP1 and second signal lines TP2 corresponds to a plurality of first color resists CR1, and the area between adjacent second signal lines TP2 and third signal lines TP3 corresponds to a plurality of third color resists CR3. Accordingly, when a user views the display panel 10 from a side angle from the +X direction towards the -X direction or from the -X direction towards the +X direction, the sides of the first signal lines TP1 will each generate reflected light of the color of the third color resist CR3, for example, blue reflected light; the sides of the second signal lines TP2 will each generate reflected light of the color of the second color resist CR2, for example, green reflected light; and the sides of the third signal lines TP3 will each generate reflected light of the color of the first color resist CR1, for example, red reflected light. The blue reflected light from the first signal line TP1, the green reflected light from the second signal line TP2, and the red reflected light from the third signal line TP3 will mix to form white light.

[0066] In this embodiment, a first color resist CR1, a second color resist CR2, a third color resist CR3, a third color resist CR3, a first color resist CR1, a second color resist CR2, a second color resist CR2, a third color resist CR3, and a first color resist CR1 are arranged sequentially in the X direction, and the above arrangement is repeated periodically in the X direction. Accordingly, the distance between adjacent first signal lines TP1 and second signal lines TP2 is equal to the distance between adjacent second signal lines TP2 and third signal lines TP3. Therefore, when a user views the display panel 10 from a side view, the white reflected light will be uniformly distributed.

[0067] In summary, the first to fourth embodiments of the present invention provide multiple special signal line configuration methods, ensuring that reflections from each signal line do not exhibit color difference at side viewing angles and are uniformly distributed. Furthermore, they avoid issues such as light leakage in dark conditions and decreased contrast at both front and side viewing angles.
