[0002] LCD panels are usually made on a motherboard. A motherboard contains multiple LCD panels. After the motherboard is made, the LCD panels are cut from the motherboard to form multiple independent LCD panels.
[0003] An LCD panel includes a display area and a non-display area surrounding the display area. The width of the non-display area is the bezel width. To enable the LCD panel to accommodate various bezel width specifications and meet the requirements of different customers, a larger bezel width is usually reserved on the motherboard, and different bezel widths are achieved by controlling the position of the cutting lines during the cutting process.
[0004] However, cutting with a large border width carries the risk of fragment breakage, which greatly reduces the cutting yield. Utility Model Content

[0052] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.
[0053] According to the first aspect of this application, Figures 1A to 4AAs shown, a display panel 1 is provided, including a display area AA and a non-display area NA located on at least one side of the display area AA. The display panel 1 includes a first substrate 20 and a second substrate 30 disposed opposite to each other, a frame adhesive 40 and at least one support portion 50. The frame adhesive 40 is disposed between the first substrate 20 and the second substrate 30 and is located within the non-display area NA. The support portion 50 is disposed between the first substrate 20 and the second substrate 30, and the support portion 50 is located on the side of the frame adhesive 40 away from the display area AA. The support portion 50 includes a first metal pad 51.
[0054] Display panel 1 can be an LCD panel, etc.
[0055] In some embodiments, the first substrate 20 and the second substrate 30 may both be made of glass.
[0056] like Figure 1A As shown, the display panel 1 includes a display area AA and a non-display area NA disposed around the periphery of the display area AA. The display area AA may be provided with multiple sub-pixels (not shown in the figure), and the sub-pixels may include red sub-pixels, green sub-pixels, and blue sub-pixels, thereby realizing color display. The non-display area NA may be provided with a driving circuit, such as a gate driving circuit, which can provide driving signals to the sub-pixels.
[0057] like Figure 1B As shown, when the display panel 1 is a liquid crystal panel, a liquid crystal layer 16 is further disposed between the first substrate 20 and the second substrate 30. The display panel 1 includes pixel electrodes 14 and common electrodes 15. The liquid crystal molecules in the liquid crystal layer 16 are deflected in the electric field formed by the pixel electrodes 14 and the common electrodes 15. The liquid crystal panel is a non-self-emissive panel and requires a backlight module for display. The backlight module is disposed on one side of the liquid crystal panel. Light emitted from the backlight module enters the display panel 1, and the liquid crystal molecules in the liquid crystal layer 16 of the display panel 1 are deflected under the action of the electric field. The transmittance of liquid crystal molecules with different deflection angles is different, thereby controlling the transmittance of the display panel 1 and realizing the brightness control of the displayed image.
[0058] The display panel 1 may include a bonding member 17, which is bonded to the first substrate 20. The bonding member 17 may include one or more of the following: a flip-chip film, a printed circuit board, a flexible printed circuit board, etc.
[0059] like Figure 1AAs shown, the frame adhesive 40 is disposed between the first substrate 20 and the second substrate 30, and is located within the non-display area NA. The frame adhesive 40 prevents leakage of liquid crystal material in the liquid crystal layer 16 and also prevents external impurities such as dust, moisture, and oxygen from entering the liquid crystal panel, affecting the display effect and lifespan of the liquid crystal. Simultaneously, the frame adhesive 40 firmly bonds the first substrate 20 and the second substrate 30 together, maintaining the overall structural stability of the liquid crystal panel. During the cutting of the display panel 1, the frame adhesive 40 supports the first substrate 20 and the second substrate 30, preventing them from breaking due to lack of support during the cutting process.
[0060] The driving circuits in the display panel 1, such as the gate driving circuit, are located inside the frame adhesive 40. This means that no driving circuits are provided in the area surrounding the frame adhesive 40.
[0061] like Figure 1A As shown, to enable the LCD panel 1 to accommodate various bezel widths and meet different customer requirements, a larger bezel width is typically reserved on the motherboard. Different bezel widths are achieved by controlling the position of the cutting lines during the cutting process. During motherboard fabrication, the bezel width is reserved at the position of the second cutting line 12. Depending on the customer's needs, cutting is performed using either the first cutting line 11 or the second cutting line 12 to obtain display panels 1 with different bezel widths. When cutting along the first cutting line 11, a smaller bezel width display panel 1 is obtained. In this case, the frame adhesive 40 can act as a support during cutting, reducing the likelihood of breakage. However, when cutting along the second cutting line 12, a larger bezel width display panel 1 is obtained. In this case, the gap between the second cutting line 12 and the frame adhesive 40 is larger, making it difficult for the frame adhesive 40 to act as a support during the cutting process, leading to a higher risk of breakage of the display panel 1.
[0062] It should be noted that the first cutting line 11 and the second cutting line 12 are virtual lines; the display panel 1 does not contain any physical structure of the first cutting line 11 and the second cutting line 12. When the display panel 1 is cut along the first cutting line 11, the outer contour of the display panel 1 is the position of the first cutting line 11. The structure surrounding the first cutting line 11 is removed and no longer exists on the display panel 1. Figure 1A As shown, when the display panel 1 is cut along the second cutting line 12, the outer contour of the display panel 1 is the position of the second cutting line 12. At this time, the internal structure of the second cutting line 12 will be preserved.
[0063] Since the area surrounding the first cutting line 11 is removed when cutting along the first cutting line 11, in order to ensure that the display panel 1 with both bezel widths can work normally, the binding member 17 in the display panel 1 is located on one side of the frame adhesive 40, and the first cutting line 11 and the second cutting line 12 coincide on this side. Figure 1AThe binding component 17 is located on the upper side of the frame adhesive 40, and the first cutting line 11 and the second cutting line 12 coincide at the upper frame.
[0064] When cutting along the second cutting line 12, which is far from the frame adhesive 40, the first substrate 20 and the second substrate 30 lack support during cutting, making them prone to breakage. To address this, a support portion 50 is provided in the non-display area NA, and the support portion 50 includes a first metal pad 51. When cutting along the second cutting line 12, the support portion 50 can provide support for the first substrate 20 and the second substrate 30, reducing the risk of breakage during cutting.
[0065] like Figures 4A to 4D As shown, the support portion 50 is disposed between the first substrate 20 and the second substrate 30. The support portion 50 may be located on the first substrate 20 or on the second substrate 30. The support portion 50 being located on the first substrate 20 means that the support portion 50 is formed on the first substrate 20 during the manufacturing process. The support portion 50 being located on the second substrate 30 means that the support portion 50 is formed on the second substrate 30 during the manufacturing process.
[0066] In some embodiments, the first substrate 20 may be an array substrate, and the second substrate 30 may be a color filter substrate.
[0067] In some embodiments, the display panel 1 can be a color filter layer 72 on an array substrate (COA) architecture, the first substrate 20 can be an array substrate, and the second substrate 30 can be an opposing substrate.
[0068] like Figure 2 As shown, the support portion 50 is disposed between the first cutting line 11 and the second cutting line 12. The first cutting line 11 is located on the periphery of the frame adhesive 40. That is to say, the support portion 50 is located on the side of the frame adhesive 40 away from the display area AA.
[0069] In some embodiments, such as Figure 1A and Figure 2 As shown, the display area AA can be a rectangular area. Multiple support parts 50 are disposed around the periphery of the display area AA. The multiple support parts 50 can be spaced apart, or the multiple support parts 50 can be connected.
[0070] In some embodiments, the plurality of support portions 50 may be spaced apart. For example, as Figure 2 As shown, each support portion 50 can correspond to one side of the display area AA, and the two support portions 50 corresponding to adjacent display areas AA on both sides are spaced apart. Alternatively, each side of the display area AA can correspond to at least two support portions 50, and the two support portions 50 are spaced apart in the extending direction of the frame adhesive 40.
[0071] In other embodiments, the support portion 50 may be connected and may surround the display area AA.
[0072] The first metal pad 51 is made of metal. For example, the first metal pad 51 can be made of any one of molybdenum (Mo), aluminum (Al), chromium (Cr), gold (Au), titanium (Ti), nickel (Ni), neodymium (Nd), and copper (Cu) or an alloy thereof.
[0073] In some embodiments, please refer to Figures 4A to 4D and Figure 1B The first metal pad 51 can be disposed on the same layer as the metal traces in the driving circuit of the display panel 1, so that the first metal pad 51 and the metal traces can be formed by the same patterning process, simplifying the manufacturing process of the display panel 1. The patterning process includes steps such as photoresist coating, exposure and development, and photoresist removal. The metal traces can be data lines, scan lines, etc. in the display panel 1.
[0074] The driving circuit may include a pixel driving circuit located within the display area AA. The pixel driving circuit includes multiple thin-film transistors 80, each including an active portion 84, a gate 81, a source 82, and a drain 83. The gate 81 is disposed on the same layer as the scan lines of the display panel 1, and the source 82 is disposed on the same layer as the data lines of the display panel 1. The drain 83 is electrically connected to the pixel electrode 14, providing a driving voltage to the pixel electrode 14.
[0075] This means that when data lines, scan lines, etc. are disposed on the first substrate 20, the first metal pad 51 can be disposed on the first substrate 20; when data lines, scan lines, etc. are disposed on the second substrate 30, the first metal pad 51 can be disposed on the second substrate 30. In other words, the first metal pad 51 and the data lines, scan lines, etc. are located on the same substrate.
[0076] Optionally, such as Figure 2 , Figure 3 and Figure 4A As shown, the first metal pad 51 includes a plurality of first metal sub-parts 511, which are located on the same side of the frame adhesive 40 and extend along the extension direction of the frame adhesive 40; and / or, the first metal pad 51 includes a plurality of second metal sub-parts 512, which are located on the same side of the frame adhesive 40 and extend along the extension direction perpendicular to the extension direction of the frame adhesive 40.
[0077] like Figure 1A As shown, the frame adhesive 40 surrounds the display area AA. The same side of the frame adhesive 40 refers to the same side of the frame adhesive 40 that is furthest from the display area AA. That is to say, the same side of the frame adhesive 40 refers to the left side of the frame adhesive 40, or the right side of the frame adhesive 40, or the upper side of the frame adhesive 40, or the lower side of the frame adhesive 40.
[0078] In some embodiments, such as Figure 3 and Figure 4A As shown, the first metal pad 51 includes a plurality of first metal sub-parts 511, which extend along the extending direction of the frame adhesive 40. That is, the first metal sub-parts 511 have the same extending direction as the frame adhesive 40. By setting the extending direction of the first metal sub-parts 511 to be the same as the extending direction of the frame adhesive 40, the first metal sub-parts 511 can provide support over a longer distance in the extending direction of the second cutting line 12.
[0079] It should be understood that, such as Figure 3 As shown, when the first metal sub-part 511 extends in one direction, the size of the first metal sub-part 511 in the extension direction is greater than the size of the first metal sub-part 511 in the direction perpendicular to the extension direction. That is, the long side of the first metal sub-part 511 is located in the extension direction, and the short side is located in the direction perpendicular to the extension direction.
[0080] like Figure 3 As shown, multiple first metal sub-parts 511 on the same side of the frame adhesive 40 extend in the same direction, and two adjacent first metal sub-parts 511 can be arranged in a direction perpendicular to the extension direction of the frame adhesive 40.
[0081] In some embodiments, such as Figure 3 As shown, the first metal pad 51 includes a plurality of second metal sub-parts 512, which are located on the same side of the frame adhesive 40 and extend in a direction perpendicular to the extension of the frame adhesive 40. Adjacent second metal sub-parts 512 are arranged in a direction perpendicular to the extension of the frame adhesive 40.
[0082] By providing multiple first metal sub-parts 511 and / or multiple second metal sub-parts 512 on the same side of the frame adhesive 40, the first substrate 20 and the second substrate 30 can be supported, reducing the risk of breakage when the first substrate 20 and the second substrate 30 are cut along the second cutting line 12.
[0083] Optionally, such as Figure 3 As shown, the first metal pad 51 includes a plurality of first metal sub-parts 511 and a plurality of second metal sub-parts 512. The second metal sub-parts 512 located on the same side of the frame adhesive 40 intersect with the first metal sub-parts 511 to form a grid, thereby improving the support strength of the first metal pad 51 and further reducing the risk of breakage during cutting.
[0084] In some embodiments, the first metal sub-part 511 and the second metal sub-part 512 are disposed on the same layer.
[0085] In some other embodiments, the first metal sub-part 511 and the second metal sub-part 512 are disposed in different layers.
[0086] Optionally, such as Figure 3 As shown, in the first metal pad 51 located on the same side of the frame adhesive 40, the distance s1 between two adjacent first metal sub-parts 511 is smaller than the distance s2 between two adjacent second metal sub-parts 512.
[0087] Two adjacent first metal sub-parts 511 are arranged in a direction perpendicular to the extension direction of the frame adhesive 40. Two adjacent second metal sub-parts 512 are arranged in the extension direction of the frame adhesive 40. The distance s1 between two adjacent first metal sub-parts 511 is smaller than the distance s2 between two adjacent second metal sub-parts 512, that is, the first metal sub-parts 511 are distributed more densely, and the second metal sub-parts 512 are distributed more sparsely.
[0088] Since the extension direction of the second cutting line 12 is the same as the extension direction of the frame adhesive 40, that is, the extension direction of the first metal sub-part 511 is the same as the extension direction of the second cutting line 12, the first metal sub-part 511 is set more densely, which can more effectively support the area near the second cutting line 12 and further reduce the risk of fragmentation during cutting.
[0089] Optionally, such as Figures 4A to 4D As shown, the support portion 50 is disposed on the first substrate 20. The support portion 50 also includes a plurality of second metal pads 52 and / or a plurality of organic material pads 53, the second metal pads 52 and / or organic material pads 53 being located on the side of the first metal pad 51 away from the first substrate 20.
[0090] The support portion 50 is disposed on the first substrate 20, that is, the support portion 50 is fabricated on the first substrate 20. The support portion 50 can be formed by forming a film layer on the first substrate 20 and then using a patterning process on the film layer.
[0091] In some embodiments, such as Figure 4D As shown, the support portion 50 also includes a plurality of second metal pads 52. The second metal pads 52 are disposed in a different layer from the first metal pads 51, and the second metal pads 52 are located on the side of the first metal pads 51 that is away from the first substrate 20. That is to say, in terms of film formation sequence, the first metal pads 51 are formed first, and then the second metal pads 52 are formed.
[0092] Please see Figure 1BThe first metal pad 51 can be disposed on the same layer as a metal trace in the driving circuit of the display panel 1 that is closer to the first substrate 20. For example, the first metal pad 51 can be disposed on the same layer as the gate 81 of the thin-film transistor 80. With the above arrangement, the first metal pad 51 can be formed using the same patterning process as the metal trace in the driving circuit, thereby simplifying the manufacturing process of the display panel 1. The second metal pad 52 can be disposed on the same layer as a metal trace in the driving circuit of the display panel 1 that is relatively far from the first substrate 20. For example, the second metal pad 52 can be disposed on the same layer as the source 82 of the thin-film transistor 80. With the above arrangement, the second metal pad 52 can be formed using the same patterning process as the metal trace in the driving circuit, thereby simplifying the manufacturing process of the display panel 1.
[0093] In some embodiments, the material of the second metal pad 52 may be any one of molybdenum (Mo), aluminum (Al), chromium (Cr), gold (Au), titanium (Ti), nickel (Ni), neodymium (Nd) and copper (Cu) or an alloy thereof.
[0094] In some embodiments, such as Figures 4A to 4C As shown, the support portion 50 also includes multiple organic material pads 53.
[0095] The organic material pad 53 is made of organic material. In the manufacturing process of the display panel 1, the thickness of the organic material is greater than that of the metal traces, which can better fill the gap between the first substrate 20 and the second substrate 30, thereby providing a supporting effect.
[0096] The organic material pad 53 can be disposed in the same layer as the organic film layer in the display panel 1, thereby simplifying the manufacturing process of the display panel 1. Please refer to [link / reference]. Figure 1B The material of the organic material pad 53 can be the same as the material of at least one of the planarization layer 71, color filter layer 72, and support pillar 73 of the display panel 1.
[0097] In some embodiments, the material of the planarization layer 71 may be one of acrylic resin, epoxy resin, and perfluoroalkoxy resin (PFA).
[0098] In some embodiments, the color filter layer 72 includes a red color filter, a green color filter, and a blue color filter, with one color filter corresponding to one sub-pixel. The red sub-pixel corresponds to the red color filter, the green sub-pixel corresponds to the green color filter, and the blue sub-pixel corresponds to the blue color filter.
[0099] When the material of the organic material pad 53 is the same as that of the color filter layer 72, the organic material pad 53 can be one or a combination of red color resist, green color resist, blue color resist, etc.
[0100] In some embodiments, the support pillar 73 is used to maintain the thickness of the liquid crystal cell, i.e., the distance between the first substrate 20 and the second substrate 30. The material of the support pillar 73 can be resin, such as acrylate resin.
[0101] It should be noted that when the material of the organic material pad 53 includes the color filter layer 72, the display panel 1 can be a panel with a COA architecture.
[0102] In some embodiments, such as Figure 1B and Figure 4C As shown, the support portion 50 also includes a plurality of second metal pads 52 and organic material pads 53. The organic material pads 53 are disposed on the side of the second metal pads 52 away from the first substrate 20.
[0103] In some embodiments, the organic material pad 53 comprises a material with red color resist.
[0104] In some embodiments, the organic material pad 53 comprises a material with a green color resist.
[0105] In some embodiments, the organic material pad 53 comprises a blue color resist material.
[0106] In some embodiments, the organic material pad 53 includes the material of the support column 73.
[0107] In some embodiments, the organic material pad 53 includes the material of the flattening layer 71 and the material of the support column 73.
[0108] It should be noted that in some embodiments, the support portion 50 further includes the material of an inorganic film layer 60, which can be continuously disposed with the inorganic film layer 60 in the display area AA. For example, the material of the inorganic film layer 60 can be any one or more of silicon oxide, silicon nitride, or silicon oxynitride. Through the above arrangement, the thickness of the support portion 50 can be further increased, thereby improving the support effect.
[0109] Please see Figure 1B The inorganic film layer 60 can be a stack of one or more of the gate insulating layer 61, passivation layer 62, etc. in the display panel 1. The greater the thickness of the support portion 50, the better the support effect on the first substrate 20 and the second substrate 30. Therefore, the support portion 50 can be configured as a stack of as many materials as possible to improve the support effect of the support portion 50.
[0110] Optionally, such as Figure 3 and Figure 5As shown, multiple second metal pads 52 and / or multiple organic material pads 53 located on the same side of the frame adhesive 40 extend along the extension direction of the frame adhesive 40, and the orthographic projections of the multiple second metal pads 52 and / or multiple organic material pads 53 on the first substrate 20 overlap with the orthographic projection of the first metal sub-part 511 on the first substrate 20.
[0111] Multiple second metal pads 52 and / or multiple organic material pads 53 located on the same side of the frame adhesive 40 extend along the extending direction of the frame adhesive 40. That is to say, the first metal sub-part 511, the second metal pads 52, and / or the organic material pads 53 located on the same side of the frame adhesive 40 all extend along the extending direction of the frame adhesive 40. With the above arrangement, the support column 73 can provide support over a longer distance in the extending direction of the second cutting line 12.
[0112] In some embodiments, such as Figure 3 and Figure 5 As shown, the orthographic projections of the plurality of second metal pads 52 and / or the plurality of organic material pads 53 on the first substrate 20 overlap with the orthographic projection of the first metal sub-part 511 on the first substrate 20. This means that the second metal pads 52 and / or the organic material pads 53 are stacked in the thickness direction of the display panel 1. Through this arrangement, the second metal pads 52 can fix the organic material pads 53, preventing the organic material pads 53 from moving, thereby supporting the area near the second cutting line 12, reducing the risk of breakage, and improving the cutting yield.
[0113] Optionally, such as Figure 5 As shown, in the support portion 50 located on the same side of the frame adhesive 40, the distance s3 between two adjacent second metal pads 52 and / or the distance s4 between two adjacent organic material pads 53 is greater than the distance s1 between two adjacent first metal sub-parts 511.
[0114] like Figure 5 As shown, in the support portion 50 located on the same side of the frame adhesive 40, two adjacent second metal pads 52 are arranged in a direction perpendicular to the extending direction of the frame adhesive 40. Two adjacent organic material pads 53 are arranged in a direction perpendicular to the extending direction of the frame adhesive 40.
[0115] In all the second metal pads 52, the distance s3 between at least some of the two adjacent second metal pads 52 is greater than the distance s1 between two adjacent first metal sub-parts 511. That is to say, the second metal pads 52 are sparsely distributed and the first metal sub-parts 511 are densely distributed.
[0116] like Figure 3 As shown, the distance s4 between two adjacent organic material pads 53 is greater than the distance s1 between two adjacent first metal sub-parts 511. This means that the distribution of organic material pads 53 is sparser and the distribution of first metal sub-parts 511 is denser.
[0117] Optionally, such as Figure 4C and Figure 4D As shown, the orthographic projection of a second metal pad 52 on the first substrate 20 lies within the orthographic projection of a first metal sub-part 511 on the first substrate 20. That is, the area of the orthographic projection of the second metal pad 52 on the substrate is less than or equal to the area of the orthographic projection of the first metal sub-part 511 on the first substrate 20. Through this arrangement, the second metal pad 52 and the first metal sub-part 511 can form a pyramid-like structure, smaller at the top and larger at the bottom, thereby increasing the structural stability of the support portion 50.
[0118] Optionally, such as Figure 4A and Figure 4B As shown, an organic material pad 53 is disposed corresponding to two first metal sub-parts 511, and the organic material pad 53 covers the gap between two adjacent first metal sub-parts 511 and a portion of the first metal sub-parts 511. That is, one organic material pad 53 covers the gap between two adjacent first metal sub-parts 511, one end of one first metal sub-part 511 is near the gap, and the other end of the other first metal sub-part 511 is near the gap. Through this arrangement, the organic material pad 53 and the first metal sub-parts 511 can form a pyramid-like structure, smaller at the top and larger at the bottom, thereby increasing the structural stability of the support portion 50.
[0119] In some embodiments, such as Figure 3 As shown, the length of the organic material pad 53 in the extending direction can be greater than the length of the first metal sub-part 511 in the extending direction. That is, the organic material pad 53 can extend beyond the first metal sub-part 511 near the corner 1a.
[0120] Optionally, such as Figure 2 and Figure 6 As shown, the display panel 1 includes two support portions 50 corresponding to the frame adhesive 40 on the adjacent two sides, and the two support portions 50 are spaced apart at the corner 1a of the display panel 1.
[0121] Corner 1a refers to the connection point between one side bezel and the other side bezel of the display panel 1. An alignment mark (not shown in the figure) is set at corner 1a in the non-display area NA of the display panel 1. In order to avoid the support part 50 affecting the recognition of the alignment mark, the two adjacent support parts 50 are disconnected at corner 1a.
[0122] Optionally, such as Figure 6 As shown, at least two support portions 50 are provided on the side of the frame adhesive 40 away from the display area AA, and one support portion 50 is located on the side of the other support portion 50 away from the frame adhesive 40.
[0123] When the display panel 1 is compatible with more than two bezels, the number of support portions 50 can be greater than two, and one support portion 50 is located on the side of another support portion 50 away from the frame adhesive 40. That is to say, multiple support portions 50 can be arranged in a direction perpendicular to the extending direction of the frame adhesive 40.
[0124] like Figure 6 As shown, when the display panel 1 is compatible with three bezels, the display panel 1 has a first cutting line 11, a second cutting line 12, and a third cutting line 13. The third cutting line 13 is located on the side of the second cutting line 12 away from the display area AA. On the same side of the frame adhesive 40, there can be two support portions 50, one of which is disposed between the first cutting line 11 and the second cutting line 12, and the other support portion 50 is disposed between the second cutting line 12 and the third cutting line 13.
[0125] It should be noted that, in order to avoid the support part 50 being located on the cutting line and thus increasing the cutting difficulty, two adjacent support parts 50 are spaced apart in the extension direction perpendicular to the frame adhesive 40, that is, the support part 50 does not overlap with any cutting line.
[0126] In some embodiments, the display panel 1 can also be compatible with more than three bezels. When the display panel 1 is compatible with more than three bezels, a support portion 50 is provided between two adjacent cut lines, and the plurality of support portions 50 are arranged in a direction perpendicular to the frame adhesive 40.
[0127] According to the second aspect of this application, such as Figure 7 As shown, a display terminal 2 is provided, including the display panel 1 described above.
[0128] In this embodiment, as Figure 7 As shown, the display terminal 2 includes a display panel 1 and a terminal body 3, which are combined into one unit.
[0129] In this embodiment, the display terminal 2 can be any product or component with display function, such as a mobile phone, tablet computer, television, monitor, laptop computer, digital photo frame, or navigator.
