Detailed Description
Like reference numerals refer to like elements throughout the specification. It will be understood that when an element such as a layer, film, region, or substrate is referred to as being "on" or "connected to" another element, it can be directly on or connected to the other element or intervening elements may also be present. In contrast, when an element is referred to as being "directly on" or "directly connected to" another element, there are no intervening elements present. As used herein, "connected" may refer to physical and/or electrical connections. Further, "electrically connected" or "coupled" may mean that there are additional elements between the elements.
It will be understood that, although the terms "first," "second," "third," etc. may be used herein to describe various elements, components, regions, layers and/or sections, these elements, components, regions, layers and/or sections should not be limited by these terms. These terms are only used to distinguish one element, component, region, layer or section from another element, component, region, layer or section. Thus, a "first element," "component," "region," "layer" or "portion" discussed below could be termed a second element, component, region, layer or portion without departing from the teachings herein.
The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms, including "at least one", unless the content clearly indicates otherwise. "or" means "and/or". As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items. It will be further understood that the terms "comprises" and/or "comprising," when used in this specification, specify the presence of stated features, regions, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, regions integers, steps, operations, elements, components, and/or groups thereof.
Furthermore, relative terms, such as "lower" or "bottom" and "upper" or "top," may be used herein to describe one element's relationship to another element, as illustrated. It will be understood that relative terms are intended to encompass different orientations of the device in addition to the orientation depicted in the figures. For example, if the device in one of the figures is turned over, elements described as being on the "lower" side of other elements would then be oriented on "upper" sides of the other elements. Thus, the exemplary term "lower" can encompass both an orientation of "lower" and "upper," depending on the particular orientation of the figure. Similarly, if the device in one of the figures is turned over, elements described as "below" or "beneath" other elements would then be oriented "above" the other elements. Thus, the exemplary terms "below" or "beneath" can encompass both an orientation of above and below.
Unless defined otherwise, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and the present invention and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.
Fig. 1 is a schematic diagram of a display device 100 according to an embodiment of the invention. The display device 100 may include a gate driving circuit 110, a source driving circuit 120, and a pixel array 101. The gate driving circuit 110 may generate and provide a plurality of scan signals G1, \8230 \ 8230;, GN to the pixel array 101 to turn on a plurality of switches in the pixel array 101, where N is a natural number. The source driving circuit 120 may generate a plurality of data voltages D1, \8230:, DM, and provide the data voltages D1, \8230 \ 8230;, DM to the pixel array 101, so that the pixel array 101 performs a display operation according to the data voltages D1, \8230;, DM, wherein M is a natural number. Thus, the display device 100 can display an image.
Fig. 2 is a partial schematic diagram of the display device 100 according to the embodiment of the invention. In the present embodiment, the plurality of scan lines are used for providing a plurality of scan signals G1, \8230 \ 8230, and G3, and the scan lines extend along the first direction DR 1. In the present embodiment, a plurality of data lines are used to provide a plurality of data voltages D1, \8230: \, D3 to a plurality of pixel electrodes, and the data lines extend along the second direction DR2. In the present embodiment, the first pixel electrode 10 and the second pixel electrode 20 are disposed between a plurality of scan lines for providing scan signals G1 and G2 and a plurality of data lines for providing data voltages D1 and D2. In other words, the first pixel electrode 10 and the second pixel electrode 20 are disposed between the scan line for providing the scan signals G1 and G2 and the data line for providing the data voltages D1 and D2.
In the present embodiment, the first pixel electrode 10 is substantially in the shape of a right triangle, wherein the first angle P1 of the first pixel electrode 10 is substantially a right angle, and the second angle P2 is smaller than or equal to the third angle P3. The first side (i.e., the side opposite to the first corner P1) of the first pixel electrode 10 is substantially parallel to the third direction DR3, the second side (i.e., the side opposite to the second corner P2) of the first pixel electrode 10 is substantially parallel to the first direction DR1, and the third side (i.e., the side opposite to the third corner P3) of the first pixel electrode 10 is substantially parallel to the second direction DR2. In some embodiments, the first angle P1 may be defined as an angle between the second edge and the third edge of the first pixel electrode 10, the second angle P2 may be defined as an angle between the second edge and the third edge of the first pixel electrode 10, and the third angle P3 may be defined as an angle between the first edge and the third edge of the first pixel electrode 10.
In the present embodiment, the second pixel electrode 20 has a substantially right triangle shape, wherein the first angle P1a of the second pixel electrode 20 is substantially right, and the second angle P2a is smaller than or equal to the third angle P3a. The first side of the second pixel electrode 20 (i.e., the side opposite to the first corner P1 a) is substantially parallel to the third direction DR3, the second side of the second pixel electrode 20 (i.e., the side opposite to the second corner P2 a) is substantially parallel to the first direction DR1, and the third side of the second pixel electrode 20 (i.e., the side opposite to the third corner P3 a) is substantially parallel to the second direction DR2. In some embodiments, the first angle P1a may be defined as an angle between the second edge and the third edge of the second pixel electrode 20, the second angle P2a may be defined as an angle between the second edge and the third edge of the second pixel electrode 20, and the third angle P3a may be defined as an angle between the first edge and the third edge of the second pixel electrode 20. In some embodiments, the angles of the interior corners P1-P3 of the first pixel electrode 10 are substantially equal to the angles of the interior corners P1a-P3a of the second pixel electrode 20.
With the above arrangement, the display device 100 having the triangular pixel electrode can be realized, and the display device 100 can have high resolution (equivalent to dividing a single rectangular pixel electrode into two triangular pixel electrodes). In addition, in different embodiments, two adjacent pixel electrodes (corresponding to the color filters of the same color) may also receive data voltages corresponding to different gray scale values to mix more gray scales. For example, in the case where the first pixel electrode 10 and the second pixel electrode 20 correspond to color filters of the same color, if the first pixel electrode 10 receives a data voltage corresponding to a gray-scale value of 128 and the second pixel electrode 20 receives a data voltage corresponding to a gray-scale value of 129, the first pixel electrode 10 and the second pixel electrode 20 can be mixed to have a gray-scale value substantially equal to 128.5.
In the present embodiment, the first switch SW1 is coupled to a scan line for providing a scan signal G1 and a data line for providing a data voltage D1. In the present embodiment, the first pixel electrode 10 is coupled to a scan line for providing a scan signal G1 and a data line for providing a data voltage D1 through a first switch SW 1. In the present embodiment, the second switch SW2 is coupled to a scan line for providing the scan signal G3 and a data line for providing the data voltage D2. In the present embodiment, the second pixel electrode 20 is coupled to a scan line for providing a scan signal G2 and a data line for providing a data voltage D2 through a second switch SW 2. In one embodiment, the first switch SW1 is turned on in response to the scan signal G1 to provide the data voltage D1 to the first pixel electrode 10. In one embodiment, the second switch SW2 is turned on in response to the scan signal G2 to provide the data voltage D2 to the second pixel electrode 20.
In one embodiment, the display device 100 has a light-shielding layer BM. The light-shielding layer BM is used to shield the data lines, the scan lines, and the switches (e.g., switches SW1 and SW 2). In addition, at least a portion of the light-shielding layer BM is used to shield a signal line (refer to the signal line SL in fig. 6A) disposed between the first pixel electrode 10 and the second pixel electrode 20, and the light-shielding layer BM is used to shield the at least a portion of the signal line substantially parallel to the third direction DR3. In an embodiment, the light shielding layer BM is used to shield the projection range of the at least one portion of the signal line on the substrate SBT (e.g., the substrate STB in fig. 6B) approximately between the projection range of the first pixel electrode 10 on the substrate and the projection range of the second pixel electrode 20 on the substrate.
By using the arrangement in the embodiment of the present disclosure, the shielding range of the light-shielding layer BM can be reduced, and the display device 100 has a larger aperture ratio. For example, referring to fig. 3A to 3C, the pixel electrodes are arranged in a triangle shape at different resolutions, which facilitates to arrange part of the light shielding layers for shielding the switches together, and thus reduces the area of the light shielding layer BM.
In an embodiment, the display device 100 further includes a transparent electrode 50, and a projection range of the transparent electrode 50 on the substrate at least partially overlaps with a projection range of the first pixel electrode 10 on the substrate and a projection range of the second pixel electrode 20 on the substrate.
Referring to fig. 5A, in an embodiment, the third pixel electrode 30 is substantially the same as the second pixel electrode 20, and the angles of three inner corners P1b, P2b, and P3b of the third pixel electrode 30 are respectively substantially equal to the angles of the inner corners P1a-P3a of the second pixel electrode 20. In one embodiment, the third pixel electrode 30 is substantially symmetrical to the second pixel electrode 20. In one embodiment, the switch corresponding to the third pixel electrode 30 is turned on according to the scan signal G3 to provide the data voltage D2 (the voltage value may be different from the voltage value provided to the second pixel electrode 20) to the third pixel electrode 30. In one embodiment, the third pixel electrode 30 is disposed adjacent to one side of the second pixel electrode 20 (i.e., opposite to the angle P2 a) substantially parallel to the first direction DR 1. In one embodiment, the scan lines for transmitting the scan signals G2 and G3 are disposed between the second pixel electrode 20 and the third pixel electrode 30.
In one embodiment, the fourth pixel electrode 40 is substantially the same as the first pixel electrode 10, and the angles of the three inner corners P1c, P2c, P3c of the fourth pixel electrode 40 are respectively substantially equal to the angles of the inner corners P1-P3 of the first pixel electrode 10. In one embodiment, the fourth pixel electrode 40 is substantially symmetrical to the first pixel electrode 10. In one embodiment, the switch corresponding to the fourth pixel electrode 40 is turned on according to the scan signal G4 to provide the data voltage D1 (which may have a voltage value different from the voltage value provided to the first pixel electrode 10) to the fourth pixel electrode 40. In one embodiment, the scan lines for transmitting the scan signals G2 and G3 are disposed between the first pixel electrode 10 and the fourth pixel electrode 40.
In an embodiment, the second angles P2, P2a, P2b, P2c of the first pixel electrode 10, the second pixel electrode 20, the third pixel electrode 30, and the fourth pixel electrode 40 may be between 10 degrees and 45 degrees (including 10 degrees or 45 degrees). For example, referring to fig. 4A, in the case that the single pixel is square and the single pixel is composed of three sub-pixels arranged in parallel (e.g., including a red sub-pixel (labeled R), a green sub-pixel (labeled G), and a blue sub-pixel (labeled B)), the aspect ratio of each sub-pixel is about 1. Under this setting, if the sub-pixel is a triangular sub-pixel (see fig. 4B), the diagonal θ = arctan (1/3) =18.43495 ° of the short side of the sub-pixel. If the existence of the light-shielding layer GLBM is further considered, the diagonal angle θ' of the short side of the sub-pixel will be slightly larger than the diagonal angle θ.
On the other hand, referring to fig. 4C, in the case that the single pixel is square and the single pixel is composed of four sub-pixels (for example, including a red sub-pixel (labeled R), a green sub-pixel (labeled G), a blue sub-pixel (labeled B), and a white sub-pixel (labeled W)), the aspect ratio of each sub-pixel is about 1. Under this setting, if the sub-pixel is a triangular sub-pixel, the diagonal θ = arctan (1/4) =14.036243 ° of the short side of the sub-pixel. Referring again to fig. 4D, where the single pixel is square and the single pixel is composed of four sub-pixels in a matrix (e.g., including a red sub-pixel (labeled R), a green sub-pixel (labeled R), a blue sub-pixel (labeled B), and a white sub-pixel (labeled W)), the aspect ratio of each sub-pixel is about 1. Under this setting, if the sub-pixel is a triangular sub-pixel, the diagonal θ = arctan (1) =45 ° of the short side of the sub-pixel.
It should be noted that the above angles are only examples, the second angles P2 and P2a of the first pixel electrode 10 and the second pixel electrode 20 can be set to various angles according to actual requirements, and the disclosure is not limited to the above embodiments.
Referring to fig. 5A to 5C, in one embodiment, the switches corresponding to the pixel electrodes 10, 20, 30, and 40 may be disposed at substantially the same angle of the inner corners of the pixel electrodes 10, 20, 30, and 40, respectively. For example, in the embodiment corresponding to fig. 5A, the switches corresponding to the pixel electrodes 10, 20, 30, 40 may be disposed substantially at the first corners P1, P1a, P1b, P1c of the pixel electrodes 10, 20, 30, 40, respectively. In the embodiment corresponding to fig. 5B, the switches corresponding to the pixel electrodes 10, 20, 30, 40 may be respectively disposed substantially at the third corners P3, P3a, P3B, P3c of the pixel electrodes 10, 20, 30, 40. In the embodiment corresponding to fig. 5C, the switches corresponding to the pixel electrodes 10, 20, 30, 40 may be disposed substantially at the second corners P2, P2a, P2b, P2C of the pixel electrodes 10, 20, 30, 40, respectively. Therefore, the aperture ratios of different pixel electrodes are approximately the same.
In the embodiment corresponding to fig. 5A-5C, the pixel electrode labeled "R" represents the pixel electrode corresponding to the red color filter, the pixel electrode labeled "G" represents the pixel electrode corresponding to the green color filter, and the pixel electrode labeled "B" represents the pixel electrode corresponding to the blue color filter. In the embodiments corresponding to fig. 5A-5C, the color filters of the same color corresponding to two adjacent pixel electrodes can form a triangle. For example, in the embodiments corresponding to fig. 5A-5C, the green color filters corresponding to the pixel electrodes 20 and 30 may substantially form a triangle.
In different embodiments, the switches corresponding to the pixel electrodes 10, 20, 30, 40 may be disposed substantially at the inner corners of the pixel electrodes 10, 20, 30, 40 with different angles, respectively. For example, when the switch corresponding to the pixel electrode 20 is disposed at the first angle P1a, the switch corresponding to the pixel electrode 30 is disposed at the second angle P2b or the third angle P3b; when the switch corresponding to the pixel electrode 20 is disposed at the second angle P2a, the switch corresponding to the pixel electrode 30 is disposed at the first angle P1b or the third angle P3b; when the switch corresponding to the pixel electrode 20 is disposed at the third angle P3a, the switch corresponding to the pixel electrode 30 is disposed at the first angle P1b or the second angle P2b.
Referring to FIG. 5D, the pixel electrodes 10a-40a are substantially identical to the pixel electrodes 10-40, except that they are left-right opposite. In the embodiment corresponding to fig. 5D, the switch corresponding to the pixel electrode 10a may be disposed at an acute angle of the pixel electrode 10a, the switch corresponding to the pixel electrode 20a may be disposed at a right angle of the pixel electrode 20a, the switch corresponding to the pixel electrode 30a may be disposed at an acute angle of the pixel electrode 30a, and the switch corresponding to the pixel electrode 40a may be disposed at a right angle of the pixel electrode 40 a.
Similarly, in the embodiment corresponding to fig. 5D, the pixel electrode labeled "R" represents the pixel electrode corresponding to the red color filter, the pixel electrode labeled "G" represents the pixel electrode corresponding to the green color filter, and the pixel electrode labeled "B" represents the pixel electrode corresponding to the blue color filter. In the embodiment corresponding to fig. 5D, the color filters of the same color corresponding to two adjacent pixel electrodes substantially form a parallelogram. For example, in the embodiment corresponding to fig. 5D, the green color filters corresponding to the pixel electrodes 20a and 30a may substantially form a parallelogram.
Fig. 6A is a partial schematic diagram of a display device 100 according to an embodiment of the invention. In one embodiment, the display device 100 has a plurality of signal lines SL. In one embodiment, the signal line SL has a first section, a second section, and a third section. Taking the signal line SL partially overlapped with the data lines D2 and D3, respectively, a first segment thereof is parallel to the first direction DR1 and at least partially overlapped with the data line D2, a second segment thereof is parallel to the third direction DR3a (i.e., parallel to the right-angled opposite sides of the pixel electrodes 10a and 20 a), and a third segment thereof is parallel to the first direction DR1 and at least partially overlapped with the data line D3. In some embodiments, the signal line SL may be a touch signal line for transmitting a touch signal. Note that the overlapping or partial overlapping means that the projection ranges of the signal lines and the data lines on the substrate overlap or partially overlap.
Referring further to fig. 6B, in some cases, if the second metal layer (labeled as M2) for implementing the data lines D1-D3 and the third metal layer (labeled as M3) for implementing the signal line SL in the display device 100 are overlapped, crosstalk (cross talk) is easily generated between the second metal layer and the third metal layer, which affects the signal.
In the embodiment, the first and third segments of the signal line SL are respectively overlapped with different data lines, and the second segment of the signal line SL is not overlapped with any data line, so that the crosstalk between the signal line SL and the data lines D1-D3 can be reduced.
