Description

Display device

The present invention relates to a display device, and more particularly to a display device having a non-rectangular display area.

As display technology continues to evolve, the range of applications for displays is no longer limited to rectangular structures such as televisions, monitors, laptop screens, and cell phone screens. In recent years, special applications such as wearable devices, vehicle displays, and display windows have grown rapidly, and their demand for displays has been different. Among them, non-rectangular display structures are the most special. Such non-rectangular displays include circular displays for smart watches, irregular displays for automotive dashboards, and other non-rectangular displays such as hearts, polygons, and the like.

In general, the main disadvantages of current non-rectangular displays include: uneven color of the edges of the display and rough display at the edge of the display. At the edge contour of a non-rectangular display, a complete display pixel (such as a display pixel composed of red sub-pixels, green sub-pixels, and blue sub-pixels) may be asymmetrically edged by non-rectangular displays Cutting, causing the remaining red sub-pixels, green sub-pixels, and blue sub-pixels at the edges of the display area to have different light-emitting areas, such that the non-complete display pixels produce color unevenness, thereby causing color shift And other issues. In addition, when a complete display pixel is asymmetrically cut by the edge of a non-rectangular display, if the remaining area of the pixel is less than a certain ratio (for example, 30%), the remaining pixel area will be too small to be placed. The driving circuit is so unusable that in this case, the outline of the non-rectangular display here becomes unsmooth when displayed, and the stepped rough outline shows a feeling.

SUMMARY OF THE INVENTION A primary object of the present invention is to provide a display device that improves the color unevenness and rough contour at the edge contour of a non-rectangular display area by adjusting the design of the edge display pixels.

To achieve the above object, the present invention provides a display device including a non-rectangular display area, a plurality of standard display pixels, and at least one first edge display pixel. The non-rectangular display area has a non-rectangular outline. The standard display pixels are set in the non-rectangular display area. The first edge display pixel is disposed in the non-rectangular display area and is disposed adjacent to the non-rectangular outline. The first edge display pixel is disposed between the at least one standard display pixel and the non-rectangular outline, and the area of the first edge display pixel is larger than the area of the standard display pixel.

In the present invention, a display pixel asymmetrically cut by a non-rectangular outline can be merged with an adjacent standard display pixel to become an edge display pixel having an area larger than a standard display pixel, and the edge display pixel is non-represented. The rectangular outline is placed next to it, thereby avoiding a display roughness at the outline. In addition, the area ratio of the display area of each edge sub-pixel in the edge display pixel is adjusted to be the same as the ratio of the display area area of each standard sub-pixel in the standard display pixel, thereby improving the color at the edge contour. Uneven problem.

The present invention will be further understood by those of ordinary skill in the art to which the present invention pertains. .

Please refer to Figures 1 to 4. 1 is a schematic view of a display device according to a first embodiment of the present invention, FIG. 2 is a schematic view showing a display device according to a variation of the first embodiment of the present invention, and FIG. 3 is a view showing a first embodiment of the present invention. An enlarged view of the area A, and FIG. 4 is an enlarged schematic view of a partial area of the third figure. For the convenience of description, the drawings of the present invention are only for the purpose of understanding the present invention, and the detailed proportions thereof can be adjusted according to the design requirements. As shown in FIG. 1 , FIG. 3 and FIG. 4 , the present embodiment provides a display device 101 including a non-rectangular display area 11 , a plurality of standard display pixels 20 , and at least one first edge display pixel 30 . The non-rectangular display area 11 has a non-rectangular outline 11C. In this embodiment, the non-rectangular display area 11 can be a circular display area and has a circular outline, but the invention is not limited thereto. In other embodiments of the present invention, the non-rectangular display area 11 may also be other non-rectangular shapes such as a triangle, a diamond, a trapezoid, a polygon of five or more sides, an ellipse, a heart shape, or other regular or irregular non-rectangular shapes. In addition, the display device 101 may further include one or more stacked substrates 10 for forming display pixels or other components (such as touch elements) on the substrate 10, and the substrate 10 may have a similar shape to the non-rectangular display area 11. (as shown in Fig. 1) or having a different shape (such as the display device 101' shown in Fig. 2), that is, the substrate 10 may be a rectangular substrate or a non-rectangular substrate. In addition, the display device 101 of the present embodiment may include a liquid crystal display device, an organic light emitting diode (OLED) display device, an electro-wetting display device, an electronic ink (e-ink) display device, and a plasma (plasma). A display device or field emission (FED) display device, but not limited thereto.

As shown in FIGS. 3 and 4, the standard display pixel 20 and the first edge display pixel 30 are disposed in the non-rectangular display area 11. The standard display pixel 20 is a relatively large number of main display pixels in the display device 101, and all of the standard display pixels 20 or at least a majority of the standard display pixels 20 are not disposed adjacent to the non-rectangular outline 11C. In contrast, the first edge display pixel 30 is disposed adjacent to the non-rectangular outline 11C, and the first edge display pixel 30 is disposed between the at least one standard display pixel 20 and the non-rectangular outline 11C. The area of the first edge display pixel 30 is larger than the area of the standard display pixel 20. It is further explained that each standard display pixel 20 may include a plurality of standard sub-pixels 21 such as a first color standard sub-pixel 21A, a second color standard sub-pixel 21B, and a third color standard sub-pixel 21C, the first edge. The display pixel 30 may include a plurality of first edge sub-pixels 31 such as a first color first edge sub-pixel 31A, a second color first edge sub-pixel 31B, and a third color first edge sub-pixel 31C. The first color, the second color, and the third color may be red, green, and blue, respectively, but are not limited thereto. In other words, the standard display pixel 20 of the present embodiment can be composed of three standard sub-pixels 21 respectively of red, green, and blue to have a full-color display effect, and the first edge display pixel 30 can be three. The first edge sub-pixels 31, which are red, green, and blue, respectively, also have a full-color display effect, but the invention is not limited thereto. In other embodiments of the present invention, a standard display having a full color display effect may also be formed by other different numbers (for example, two or more) and sub-pixels having different color rendering effects (for example, white, yellow, magenta, or cyan). The pixels and edges show the pixels. In addition, in this embodiment, the standard sub-pixel 21 may be a sub-pixel and extend along a first direction Y, and in the standard display pixel 20, the standard sub-pixels 21 are repeatedly arranged along a second direction X. Settings. The first direction Y is substantially orthogonal to the second direction X, but is not limited thereto. The standard display pixel 20 of the embodiment may be a rectangular display pixel, and the first edge display pixel 30 may be a non-rectangular display pixel, but the invention is not limited thereto. In other embodiments of the present invention, when the partial segment non-rectangular outline 11C disposed in close proximity to the first edge display pixel 30 is substantially parallel to the first direction Y or the second direction X, the first edge at this time The display pixel 30 can also be a rectangular display pixel.

In order to avoid that the pixel area remaining by the edge display pixels affected by the non-rectangular outline 11C is too small to be used, and thus the outline becomes unsmooth and rough when displayed, the embodiment can make a difference. The display pixels whose original area is too small in the rectangular outline 11C are merged with the adjacent standard display pixels 20 to become the first edge display pixels 30 having an area larger than the standard display pixels 20. In other words, the first edge display pixel 30 is disposed in close proximity to the non-rectangular outline 11C, and no other standard display pixels 20 are disposed between the first edge display pixel 30 and the non-rectangular outline 11C. For example, the first edge display pixel 30 of the present embodiment can be regarded as an incomplete display pixel disposed in close proximity to the non-rectangular outline 11C and a standard display pixel 20 adjacent in the first direction Y. The length of the first edge display pixel 30 in the first direction Y is greater than the length of the standard display pixel 20 in the first direction Y, but the invention is not limited thereto. In other embodiments of the present invention, the incomplete display pixels disposed adjacent to the non-rectangular outline 11C may be combined with one standard display pixel 20 adjacent in the second direction X as needed to form an area larger than the standard display. The first edge of the pixel 20 displays a pixel 30.

In addition, in order to avoid the problem of color unevenness of the edge display pixels, in the first edge display pixel 30, the display area area ratio of each first edge sub-pixel 31 is preferably equal to each standard of the standard display pixel 20. The ratio of the area of the display area of the pixel 21. The above-mentioned standard display area of the pixel 20 and the area of the first edge display pixel 30 refer to the area of the standard display pixel 20 and the outer edge display area of the pixel 30, and the display area area refers to the standard display picture. The area of the element 20 and the first edge show the area of the area actually displayed in the pixel 30. For example, in the organic light emitting diode display device, the display area of each sub-pixel can be defined by the size of the organic light-emitting material layer and the light-shielding member that may overlap with the organic light-emitting material layer; and in the liquid crystal display device, each sub-pixel The display area of the pixel can be defined by the aperture ratio of the pixel electrode, but is not limited thereto. For example, when the display area area ratio of the first color standard sub-pixel 21A, the second color standard sub-pixel 21B, and the third color standard sub-pixel 21C in the standard display pixel 20 is 1:1:1 The display area ratio of the first edge first edge sub-pixel 31A, the second color first edge sub-pixel 31B, and the third color first edge sub-pixel 31C of the first edge display pixel 30 is also better. It is 1:1:1, thereby avoiding the problem that color unevenness occurs in the first edge display pixel 30, but the present invention is not limited thereto. In other embodiments of the present invention, the first color standard sub-pixel 21A and the second of the standard display pixels 20 may also be made in accordance with color matching needs or other design considerations (eg, different colors of brightness and luminescence lifetime, etc.). The display area of the color standard sub-pixel 21B and the third color standard sub-pixel 21C are not completely the same, and in this case, the first edge displays the first color of the pixel 30, the first edge sub-pixel 31A, the first The display area area ratio of the two-color first edge sub-pixel 31B and the third color first edge sub-pixel 31C is also preferably equal to the ratio of the display area area of each standard sub-pixel 21 in the standard display pixel 20, so the first At least one of the color first edge sub-pixel 31A, the second color first edge sub-pixel 31B, and the third color first edge sub-pixel 31C may also have different size display area areas. For example, when the display area ratio of the first color standard sub-pixel 21A, the second color standard sub-pixel 21B, and the third color standard sub-pixel 21C in the standard display pixel 20 is 1:1:2 The ratio of the display area area of the first edge display first pixel sub-pixel 31A, the second color first edge sub-pixel 31B, and the third color first edge sub-pixel 31C of the first edge display is also compared. Good for 1:1:2. In addition, the display area of the first edge sub-pixel 31 is larger than the display area of the standard sub-pixel 21 corresponding to the same color in the standard display pixel 20, but is not limited thereto.

As shown in FIG. 3 and FIG. 4, the display device 101 of the present embodiment may further include at least one second edge display pixel 40 disposed in the non-rectangular display area 11, and the second edge display pixel 40 and non-rectangular The outlines 11C are arranged adjacent to each other. The second edge display pixel 40 is disposed between the at least one standard display pixel 20 and the non-rectangular outline 11C, and the area of the second edge display pixel 40 is smaller than the area of the standard display pixel 20. The second edge display pixel 40 is disposed in close proximity to the non-rectangular outline 11C, and no other standard display pixels 20 are disposed between the second edge display pixel 40 and the non-rectangular outline 11C. The second edge display pixel 40 may include a plurality of second edge sub-pixels 41 such as a first color second edge sub-pixel 41A, a second color second edge sub-pixel 41B, and a third color second edge sub-pixel 41C. The display area area ratio of each of the second edge sub-pixels 41 in the second edge display pixel 40 is preferably equal to the ratio of the display area area of each standard sub-pixel 21 in the standard display pixel 20, thereby avoiding the second edge. The problem that color unevenness occurs when the pixel 40 is asymmetrically cut by the non-rectangular outline 11C is displayed. For example, when the display area area ratio of the first color standard sub-pixel 21A, the second color standard sub-pixel 21B, and the third color standard sub-pixel 21C in the standard display pixel 20 is 1:1:1 The display area ratio of the first color second edge sub-pixel 41A, the second color second edge sub-pixel 41B, and the third color second edge sub-pixel 41C of the second edge display pixel 40 is also better. It is 1:1:1, thereby avoiding the problem of color unevenness in the second edge display pixel 40, but the invention is not limited thereto. In other embodiments of the present invention, the first color standard sub-pixel 21A, the second color standard sub-pixel 21B, and the third color standard in the standard display pixel 20 may also be made in view of color matching needs or other design considerations. The display area of the pixel 21C is not completely the same, and in this case, the second edge displays the first color second edge sub-pixel 41A of the pixel 40, the second color second edge sub-pixel 41B, and the third The display area area ratio of the color second edge sub-pixel 41C is also preferably equal to the display area area ratio of each standard sub-pixel 21 in the standard display pixel 20, so the first color second edge sub-pixel 41A, the second color At least one of the second edge sub-pixel 41B and the third color second edge sub-pixel 41C may also have different size display area areas. In addition, the display area of the second edge sub-pixel 41 is smaller than the display area of the standard sub-pixel 21 corresponding to the same color in the standard display pixel 20, but is not limited thereto.

When the edge of the design pixel is displayed, if the pixel area of the edge display pixel affected by the non-rectangular contour line 11C is greater than a predetermined percentage of the area of the standard display pixel 20, the edge display pixel is designed to be the first The two edges display pixels 40; in contrast, if the remaining pixel area of the edge display pixel affected by the non-rectangular outline 11C is smaller than a predetermined percentage of the area of the standard display pixel 20, the edge must be displayed on the edge. It merges with an adjacent standard display pixel 20 to become the first edge display pixel 30. The above predetermined percentage may be between 30% and 70% depending on design considerations, but is not limited thereto. For example, as shown in FIG. 5, the area of the third edge display pixel 50 in the display device 100 is less than 30% of the area of the standard display pixel 20 due to the influence of the non-rectangular outline 11C, so When the predetermined percentage is 30%, the third edge display pixel 50 may be merged with the adjacent standard display pixel 20 to become the first edge display pixel 30 shown in FIG. Therefore, when the predetermined percentage is 30%, the area of the first edge display pixel 30 may be less than 130% of the area of the standard display pixel 20, and the area of the second edge display pixel 40 may be greater than or equal to the standard display pixel. 30% of the area of 20. Similarly, when the predetermined percentage is 70%, the area of the first edge display pixel 30 may be less than 170% of the area of the standard display pixel 20, and the area of the second edge display pixel 40 may be greater than or equal to the standard display picture. 70% of the area of the prime 20.

With the arrangement of the first edge display pixel 30 and the second edge display pixel 40 of the present embodiment, when the non-rectangular outline 11C cuts the edge display pixels at different angles, the edge contour of the non-rectangular display area 11 can still be ensured. There are no problems with the display of roughness and uneven color. In addition, the above-mentioned display area may be affected by different structural design factors in different kinds of display devices. For example, in the organic light emitting diode display device, the display area of each subpixel can be defined by the size of the organic light emitting material layer and the light shielding member that may overlap with the organic light emitting material layer; on the other hand, in the liquid crystal display In the device, the display area of each sub-pixel can be defined by a pixel electrode, a common electrode, a color filter, and a possible light-shielding member (for example, a black matrix), but is not limited thereto.

The different embodiments of the present invention are described below, and in order to simplify the description, the following description will be mainly described with respect to the different parts of the embodiments, and the same parts will not be repeated. In addition, the same elements in the embodiments of the present invention are denoted by the same reference numerals to facilitate the comparison between the embodiments.

Please refer to Figures 6 to 8. 6 is an enlarged schematic view of a display device according to a second embodiment of the present invention, and FIG. 7 is a schematic view showing a thin film transistor of a standard sub-pixel in the display device of the embodiment, and FIG. 8 is a view A schematic diagram of a thin film transistor located at a first edge sub-pixel in the display device of the present embodiment. As shown in FIG. 6, the embodiment provides a display device 102. The difference from the first embodiment is that, in this embodiment, the standard sub-pixel 21 can include a standard illumination area 22, and the first edge is The pixel 31 may include a plurality of first edge light-emitting regions 32, and the second edge sub-pixel 41 may include a second edge light-emitting region 42. When the display device 102 is an organic light emitting diode display device, in the first edge subpixel 31, each of the first edge light emitting regions 32 may be an organic light emitting material evaporation region and connected by a trace (not shown). Corresponding anodes (not shown) of the first edge light-emitting regions 32, but not limited thereto. In this embodiment, the total display area of each of the first edge light-emitting regions 32 of the first edge sub-pixel 31 is larger than the display area of the standard light-emitting area 22 of the standard sub-pixel 21, and the second edge-emitting area 42 is The display area is smaller than the display area of the standard illuminating area 22 of the standard sub-pixel 21, but is not limited thereto. It should be noted that when the display device 102 is an organic light emitting diode display device, since the size of the first edge light emitting region 32 and the second edge light emitting region 42 are different from the size of the standard light emitting region 22, the driving film must be electrically charged. The channel width-to-length ratio (W/L) of the crystal is adjusted such that the display brightness of the first edge sub-pixel 31 and the second edge sub-pixel 41 is the same as that of the standard sub-pixel 21.

Further, the brightness of the organic light-emitting region is proportional to the current density, and the current density is substantially equal to the driving current/light-emitting area, and the driving current is proportional to the channel width-to-length ratio of the corresponding driving thin film transistor. Since the total display area of the first edge light-emitting area 32 in the first edge sub-pixel 31 is larger than the display area area of the standard light-emitting area 22 of the standard sub-pixel 21, the driving film in the first edge sub-pixel 31 is electrically The channel width to length ratio of the crystal needs to be larger than the channel width to length ratio of the driving thin film transistor in the standard subpixel 21. The second edge illuminating region 42 of the second edge sub-pixel 41 is smaller than the standard illuminating region 22 of the standard sub-pixel 21, so the channel width-to-length ratio of the driving thin film transistor in the second edge sub-pixel 41 is smaller than the standard. The channel width to length ratio of the driving thin film transistor in the subpixel 21 . For example, as shown in FIGS. 6-8, the display device 102 may further include a plurality of first thin film transistors T1 and a plurality of second thin film transistors T2. The first thin film transistor T1 is disposed in the standard sub-pixel 21, and the second thin film transistor T2 is disposed in the first edge sub-pixel 31. The channel width-to-length ratio of the second thin film transistor T2 is different from that of the first thin film transistor. T1 channel width to length ratio. In the first thin film transistor T1 of the standard sub-pixel 21, the first channel region CH1 between the first source S1 and the first drain D1 has a channel width to length ratio; and at the first edge sub-pixel In the second thin film transistor T2 of 31, the second channel region CH2 between the second source S2 and the second drain D2 has a different channel width to length ratio. In this embodiment, the display area of the first edge sub-pixel 31 is larger than the display area of the standard sub-pixel 21, so that the channel width of the second thin film transistor T2 is better than that of the first thin film transistor T1. The aspect ratio, thereby improving the brightness uniformity between the edge display pixels and the standard display pixels. In this embodiment, the first gate electrode G1 and the second gate G2 of the first thin film transistor T1 and the second thin film transistor T2 are both disposed under the channel region and can be regarded as a bottom gate film. The transistor is, but not limited to, this. In addition, in this embodiment, the channel width to length ratio is changed by adjusting the channel width of the second thin film transistor T2, but the invention is not limited thereto. In other embodiments of the invention, it is also possible to adjust only the channel length or both the channel width and the channel length as desired.

Please refer to Figure 9. Fig. 9 is an enlarged schematic view showing a display device of a third embodiment of the present invention. As shown in FIG. 9, the present embodiment provides a display device 103, which is different from the second embodiment in that each of the first edge sub-pixels 31 of the present embodiment includes only one first edge light-emitting region 32. The display area of the first edge light-emitting area 32 is larger than the area of the display area of the standard light-emitting area 22. In addition, as shown in FIG. 9, the display device 103 includes a plurality of signal lines (eg, gate lines GL or/and data lines DL), a plurality of first thin film transistors T1, a plurality of second thin film transistors T2, and a plurality of A third thin film transistor T3. The first thin film transistor T1 is disposed in the standard sub-pixel 21, the second thin film transistor T2 is disposed in the first edge sub-pixel 31, and the third thin film transistor T3 is disposed in the second edge sub-pixel 41. The data line DL is disposed in the non-rectangular display area 11 and extends along the first direction Y, and the data line DL is coupled to the first source S1 of the first thin film transistor T1 and the second source S2 of the second thin film transistor T2. The third source S3 of the third thin film transistor T3 is connected. The gate line GL is disposed in the non-rectangular display area 11 and extends along the second direction X, and the gate line GL and the first gate G1 of the first thin film transistor T1 and the second gate of the second thin film transistor T2 G2, the third gate G3 of the third thin film transistor T3 is connected. As shown in FIG. 9, the first edge display pixel 30 of the present embodiment has a longer length in the first direction Y, and the second thin film transistor T2 corresponding to the first edge sub-pixel 31 is the same as the first In the figure, the lower gate line GL is connected, so that the signal line connected to the third thin film transistor T3 of the second edge sub-pixel 41 is located in FIG. 9 (this embodiment is the second edge sub-pixel 41). The connected gate line GL) does not show the pixels 30 through the first edge. In other words, at least one signal line connected to the second edge sub-pixel 41 is disposed on a side of the first edge display pixel 30 in the second direction X and extends toward the first edge display pixel 30. And the signal line connected to the second edge sub-pixel 41 does not penetrate the first edge display pixel 30.

In this embodiment, since the area of the second edge display pixel 40 is different from the standard display pixel 20, the channel width of the third thin film transistor T3 is preferably different from the channel width to length ratio of the first thin film transistor T1. Thereby, the brightness uniformity between the second edge display pixel 40 and the standard display pixel 20 is adjusted. For example, in the third thin film transistor T3 of the second edge subpixel 41, the third channel region CH3 between the third source S3 and the third drain D3 has a channel width to length ratio different from The channel width to length ratio of the first channel region CH1 between the first source S1 and the first drain D1, and the area of the second edge subpixel 41 is smaller than the area of the standard subpixel 21 and the second edge is drawn The display area of the second edge light-emitting area 42 in the element 41 is smaller than the display area area of the standard light-emitting area 22 of the standard sub-pixel 21, so that the channel width of the third thin film transistor T3 is preferably smaller than that of the first thin film transistor. T1 channel width to length ratio. In this embodiment, the first gate G1, the second gate G2, and the third gate G3 of the first thin film transistor T1, the second thin film transistor T2, and the third thin film transistor T3 are disposed above the channel region. It can be regarded as a top gate thin film transistor, but is not limited thereto. In addition, in this embodiment, the channel length to length ratio is changed by adjusting the channel length of the thin film transistor, but is not limited thereto.

Please refer to Figure 10. FIG. 10 is an enlarged schematic view showing a display device according to a fourth embodiment of the present invention. As shown in FIG. 10, the present embodiment provides a display device 104, which is different from the second embodiment in that, in the display device 104, the standard sub-pixel 21 may include a standard pixel electrode 23, the first edge. The sub-pixel 31 may include a first edge pixel electrode 33, and the second edge sub-pixel 41 may include a second edge pixel electrode 43. In this embodiment, the first edge pixel electrode 33 is larger than the standard pixel electrode 23, and the second edge pixel electrode 43 is smaller than the standard pixel electrode 23, thereby corresponding to the standard sub-pixel 21, the first edge sub-pixel 31 and the second edge sub-pixel 41 have a relative area of the display area, but are not limited thereto. In addition, it should be noted that when the display device 104 is a liquid crystal display device, in addition to adjusting the size of the pixel electrode in the edge display pixel, the storage capacitor or/and the driving signal size must be adjusted according to the display area. Make sure that the edge display shows the uniformity of the display between the pixels and the standard display pixels.

Please refer to Figure 11. Fig. 11 is an enlarged schematic view showing a display device of a fifth embodiment of the present invention. As shown in FIG. 11, the present embodiment provides a display device 105 which is different from the above-described first embodiment in that the angle of the non-rectangular outline 11C of the partial region is large (can be regarded as a non-rectangular outline 11C and horizontal). The angle between the second directions X) causes the edge display pixels of the partial region to have the necessary number of sub-pixels, which can be merged with a standard display pixel 20 adjacent in the second direction X . In other words, the first edge display pixel 30 is merged by an incomplete display pixel disposed in close proximity to the non-rectangular outline 11C and a standard display pixel 20 adjacent to the aforementioned incomplete display pixel in the second direction X. Therefore, the length of the first edge display pixel 30 in the second direction X is greater than the length of the standard display pixel 20 in the second direction X, but is not limited thereto. In addition, the first edge sub-pixels 31 of the embodiment may be non-rectangular sub-pixels, respectively, and the first edge sub-pixels 31 may still have the same length as the standard sub-pixels 21 in the first direction Y, but Not limited to this. In this embodiment, at least one signal line connected to the second edge sub-pixel 41 (the data line DL connected to the second edge sub-pixel 41 in this embodiment) is disposed on the first edge display pixel 30.
