Abstract
The invention discloses a display device. The display device comprises a substrate, a pixel array, a circuit bridging structure, a first wiring area, a second wiring area and a display film layer. The pixel array is located on the substrate. The line bridging structure is positioned at one side of the pixel array. The first wiring area is located between the pixel array and the first side of the wiring bridging structure. The second routing area is located on a second side of the line bridging structure opposite to the first side. The display film layer is located on the pixel array, and an orthographic projection of the display film layer on the substrate is separated from an orthographic projection of the circuit bridging structure on the substrate. By making the line bridging structure avoid the display film layer, the risk of the line bridging structure being eroded by the electrophoretic liquid can be reduced. Through the design of two-section fan-out type wiring, the problem that a display picture is defective due to the fact that a metal material in the circuit bridging structure is corroded by electrophoretic liquid can be avoided.
Description
Technical Field
The present invention relates to a display device, and more particularly, to an electrophoretic display device.
Background
In the market of various consumer electronic products today, small-sized advertisement signs have been applied to electronic paper display devices as display screens. The electronic ink layer of the electronic paper display device is mainly composed of electrophoretic fluid and white, black or color particles doped in the electrophoretic fluid. By applying voltage to the display medium layer, the particles can be driven to move, so that each pixel can display black, white, gray scale or color.
Generally, a Circuit bridge structure is disposed between a pixel array and a fan-out trace of a display device, and the Circuit bridge structure is required to connect a Circuit of the pixel array to an external device, such as an Integrated Circuit (IC), through a contact via. However, microcapsules (microcapsules) or microcups (microcups) in the electronic ink layer may have a risk of rupture resulting in bleeding of the electrophoretic fluid. If the metal material (e.g., ITO) of the contact via contacts the electrophoretic solution, an electrochemical reaction may occur, and the contact via may be corroded, and the edge of the display device may be defective and may not display the image.
Therefore, how to provide a display device capable of solving the above problems is one of the problems that the industry needs to invest in research and development resources to solve.
Disclosure of Invention
The present invention is directed to a display device, which can avoid the problem of the metal material in the circuit bridging structure being eroded by the electrophoretic liquid to cause the display frame to have defects.
In some embodiments, the display device includes a substrate, a pixel array, a line bridging structure, a first routing area, a second routing area, and a display film layer. The pixel array is located on the substrate. The line bridging structure is located at the edge of the pixel array. The first wiring area is located between the pixel array and the first side of the wiring bridging structure. The second routing area is located on a second side of the line bridging structure opposite to the first side. The display film layer is located on the pixel array, and an orthographic projection of the display film layer on the substrate is separated from an orthographic projection of the circuit bridging structure on the substrate.
In some embodiments, an orthographic projection of the display film layer on the substrate partially overlaps with an orthographic projection of the first routing region on the substrate.
In some embodiments, the orthographic projection of the display film layer on the substrate is separated from the orthographic projection of the second routing region on the substrate.
In some embodiments, an orthographic projection of the edge of the display film layer on the substrate is located between the pixel array and the line bridging structure.
In some embodiments, the circuit bridging structure includes a contact via electrically connecting the first wiring region and the second wiring region.
In some embodiments, the circuit bridging structure electrically connects the first wiring region and the second wiring region.
In some embodiments, the display device further includes a connecting pad, wherein the second routing region is located between the connecting pad and the circuit bridging structure.
In some embodiments, the orthographic projection of the connection pad on the substrate is separated from the orthographic projection of the circuit bridging structure on the substrate.
In some embodiments, the orthographic projection of the connection pad on the substrate is separated from the orthographic projection of the display film layer on the substrate.
In some embodiments, the display film has a notch, and the connecting pad is exposed from the notch.
In some embodiments, the display film has a gap, and the line bridging structure is exposed from the gap.
In some embodiments, the display film layer has a notch, and the second routing area is exposed from the notch.
In some embodiments, the number of the line bridging structures is two, and the line bridging structures are respectively located at two adjacent edges of the pixel array, the display device further includes a third routing area, wherein the first routing area and the third routing area are respectively located between the two line bridging structures and two edges of the pixel array, and an orthographic projection of the display film layer on the substrate is separated from an orthographic projection of the two line bridging structures on the substrate.
In some embodiments, the orthographic projections of the two adjacent edges of the display film layer on the substrate are respectively located between the two edges of the pixel array and the two-wire bridging structure.
In some embodiments, the display film layer comprises an electrophoretic material.
In the above embodiments, since the orthographic projection of the display film layer on the substrate is separated from the orthographic projection of the circuit bridging structure on the substrate, the circuit bridging structure can avoid the display film layer. Therefore, when the microcapsule or the microcups of the electrophoretic material in the display film layer are broken to cause the leakage of the electrophoretic liquid, the structural design can reduce the risk that the circuit bridging structure is corroded by the electrophoretic liquid. In other words, by the two-stage fan-out wiring design (i.e., the first wiring region and the second wiring region), the problem of display image defects caused by corrosion of the metal material (e.g., the metal layer contacting the via hole) in the circuit bridging structure by the electrophoretic solution can be avoided.

Detailed Description
In the following description, for purposes of explanation, numerous implementation details are set forth in order to provide a thorough understanding of the various embodiments of the present invention. It should be understood, however, that these implementation details are not to be interpreted as limiting the invention. That is, in some embodiments of the invention, such implementation details are not necessary. In addition, for the sake of simplicity, some conventional structures and elements are shown in the drawings in a simple schematic manner. And the thickness of layers and regions in the drawings may be exaggerated for clarity, and the same reference numerals denote the same elements in the description of the drawings.
Fig. 1 is a top view of a display device 100 according to an embodiment of the invention. Fig. 2 is a partially enlarged view of the display device 100 of fig. 1. Referring to fig. 1 and fig. 2, the display device 100 includes a substrate 110, a pixel array 120, a fan-out routing area 112, and a display film layer 160. The pixel array 120 is located on the substrate 110. The fan-out region 112 is located at a first edge 122 of the pixel array 120 and may be used to electrically connect an Integrated Circuit (IC). The display device 100 may be an electrophoretic display device, such as an Electronic paper (Electronic paper display device). The display film layer 160 contains electrophoretic material, such as microcapsules (Microcapsule) or microcups (Micocup).
As shown in fig. 2, the fan-out wiring area 112 includes a wiring bridge structure 130, a first wiring area 140, and a second wiring area 150. The line bridge structure 130 and the first routing area 140 are located at the first edge 122 of the pixel array 120. The first routing area 140 is located between the pixel array 120 and the first side 132 of the line bridging structure 130. The second routing area 150 is located on a second side 134 of the wire bridge structure 130 opposite to the first side 132.
As shown in fig. 2, the display film layer 160 is disposed on the pixel array 120, and an orthogonal projection of the display film layer 160 on the substrate 110 is separated from an orthogonal projection of the line bridge structure 130 on the substrate 110. An orthographic projection of the display film layer 160 on the substrate 110 is partially overlapped with an orthographic projection of the first wiring region 140 on the substrate 110. The orthographic projection of the display film layer 160 on the substrate 110 is separated from the orthographic projection of the second wiring region 150 on the substrate 110.
As shown in fig. 2, the circuit bridging structure 130 includes a contact via 136, and the contact via 136 can electrically connect the first wiring region 140 and the second wiring region 150. Specifically, the line bridge structure 130 may be, for example, a common electrode (Vcom), an electrostatic discharge Protection Diode (ESD Protection Diode) circuit, or any line bridge device having a contact via. In other words, the film layer 160 is shown without covering the contact via 136.
As shown in fig. 2, the display device 100 further includes a connecting pad 170, wherein the second routing region 150 is located between the connecting pad 170 and the circuit bridging structure 130. The orthographic projection of the connection pad 170 on the substrate 110 is separated from the orthographic projection of the circuit bridging structure 130 on the substrate 110. The orthographic projection of the connection pad 170 on the substrate 110 is also separated from the orthographic projection of the display film layer 160 on the substrate 110.
The film layer 160 is also shown having an edge 162. The edge 162 is located in the fan-out wire-out region 112, and an orthogonal projection of the edge 162 on the substrate 110 is located between the pixel array 120 and the wire bridge structure 130. That is, the orthographic projection of the edge 162 on the substrate 110 overlaps the first routing area 140, but does not overlap the line bridging structure 130 and the second routing area 150.
In the present embodiment, the film 160 is shown with a notch 164, and the notch 164 is defined by the edge 162. As shown in fig. 2, the bonding pads 170, the circuit bridging structures 130 and the second routing areas 150 are exposed from the notches 164. In other words, the display film 160 only covers a portion of the first wiring region 140, and does not cover the circuit bridging structure 130 and the second wiring region 150.
For example, in some embodiments, pixel array 120 includes a plurality of pixel regions. Taking fig. 2 as an example, the display device 100 includes a plurality of data lines in a vertical direction and a plurality of scan lines in a horizontal direction, and the data lines and the scan lines are interlaced and surround a plurality of pixel regions. The longitudinal data lines are directly connected to the first routing area 140 at the first edge 122. The transverse scan lines may be bent from the second edge 124 of the pixel array 120 to the first edge 122 of the pixel array 120 and connected to the first routing area 140 (not shown), and then electrically connected to the corresponding integrated circuit through another connection pad. In other words, as long as the display device 100 passes through the two-segment routing area, the circuit bridging structure 130 is far away from the edge 162 of the display film layer 160, and the orthographic projection of the circuit bridging structure with the contact via on the substrate 110 is separated from the orthographic projection of the display film layer 160 on the substrate 110.
As can be seen from the above description, since the orthographic projection of the edge 162 of the display film layer 160 on the substrate 110 is located between the pixel array 120 and the circuit bridging structure 130, and the orthographic projection of the display film layer 160 on the substrate 110 is separated from the orthographic projection of the circuit bridging structure 130 on the substrate 110, the contact via 136 of the circuit bridging structure 130 can avoid the display film layer 160. As such, when the microcapsules of the electrophoretic material in the display film layer 160 are broken to cause the electrophoretic fluid to leak, the structural design can reduce the risk of the contact via 136 being eroded by the electrophoretic fluid. In other words, by the two-stage fan-out routing design (i.e., the first routing area 140 and the second routing area 150), the line bridging structure 130 is away from the edge 162 of the display film layer 160, so as to avoid the problem that the display device 100 fails to display a complete picture due to the contact via 136 being eroded by the electrophoretic liquid.
Fig. 3 is a top view of a display device 200 according to another embodiment of the invention. Fig. 4 is an enlarged view of the display device 200 of fig. 3. In the present embodiment, the display device 200 includes a substrate 110, a pixel array 120, a fan-out wiring region 112, a fan-out wiring region 114, and a display film layer 160. The pixel array 120 has a first edge 122 and a second edge 124 that are adjacent. The fan-out routing area 112 is located at a first edge 122 of the pixel array 120, and the fan-out routing area 114 is located at a second edge 124 of the pixel array 120.
In the present embodiment, the fan-out routing area 114 has a similar structure to the fan-out routing area 112. For example, as shown in fig. 4, the line bridge structure 230 is located at the second edge 124 of the pixel array 120. The third routing area 240 is located between the pixel array 120 and the routing bridge structure 230. The fourth routing area 250 is located on the other side of the line bridging structure 230. The orthographic projection of the display film layer 160 on the substrate 110 is separated from the orthographic projection of the line bridge structure 230 on the substrate 110.
In the present embodiment, an orthographic projection of the display film layer 160 on the substrate 110 partially overlaps an orthographic projection of the third wire routing area 240 on the substrate 110. The orthographic projection of the display film layer 160 on the substrate 110 is separated from the orthographic projection of the fourth routing area 250 on the substrate 110.
In the present embodiment, the circuit bridging structure 230 also includes a contact via (not shown), and the contact via of the circuit bridging structure 230 can electrically connect the third wiring region 240 and the fourth wiring region 250.
As shown in fig. 4, the display device 100 further includes a connecting pad 270, wherein the third wiring region 240 is located between the connecting pad 270 and the circuit bridging structure 230. The orthographic projection of the connection pad 270 on the substrate 110 is separated from the orthographic projection of the line bridge structure 230 on the substrate 110. The orthographic projection of the connection pad 270 on the substrate 110 is separated from the orthographic projection of the display film layer 160 on the substrate 110.
The display film layer 160 also has an edge 262. The edge 262 is located in the fan-out wire-out region 114, and an orthographic projection of the edge 262 on the substrate 110 is located between the pixel array 120 and the wire bridge structure 230. That is, the orthographic projection of the edge 262 on the substrate 110 overlaps the third routing area 240, but does not overlap the line bridging structure 230 and the fourth routing area 250.
In this embodiment, the display film 160 further has a notch 264, and the notch 264 is defined by the edge 262. As shown in fig. 4, the connecting pad 270, the circuit bridging structure 230 and the fourth wiring region 250 are exposed from the notch 264. In other words, the display film 160 only covers a portion of the third wiring region 240, and does not cover the circuit bridging structure 230 and the fourth wiring region 250.
For example, in some embodiments, the display device 200 includes a plurality of data lines in a vertical direction and a plurality of scan lines in a horizontal direction. The longitudinal data lines are directly connected to the first routing area 140. The plurality of scan lines in the transverse direction directly connect the third routing area 240. The bonding pads 170 and 270 may be connected to corresponding integrated circuits, respectively.
As can be seen from the above description, since the orthographic projection of the edge 162 of the display film layer 160 on the substrate 110 is located between the pixel array 120 and the circuit bridging structure 130, the orthographic projection of the edge 262 of the display film layer 160 on the substrate 110 is located between the pixel array 120 and the circuit bridging structure 230, and the orthographic projection of the display film layer 160 on the substrate 110 is separated from the orthographic projection of the circuit bridging structure 130 and the circuit bridging structure 230 on the substrate 110, the contact through holes of the circuit bridging structure 130 and the circuit bridging structure 230 can avoid the display film layer 160. As such, when the microcapsules of the electrophoretic material in the display film layer 160 are broken to cause the electrophoretic liquid to leak, such a structure design can reduce the risk of the contact via being eroded by the electrophoretic liquid. In other words, by the two-segment fan-out wiring design, the problem that the display device cannot display a complete picture due to the defect caused by the erosion of the contact through hole by the electrophoretic liquid can be avoided.
Although the present invention has been described with reference to the above embodiments, it should be understood that various changes and modifications can be made therein by those skilled in the art without departing from the spirit and scope of the invention.
