Description

Technical Field

[0001] The present invention relates to an integrated circuit chip, and more particularly to an integrated integrated circuit chip for an integrated panel. Background Art

[0002] Figure 1 The following is a diagram showing an existing integrated panel. This panel 10 can be a display panel that integrates touch control. Touch electrodes (not shown) can be formed on pixel units 11, so that the display and touch sensing functions can be realized. The scan lines that display the RGB sub-pixels extend along the X-axis direction and are connected to display scan drive circuits 13L, 13R, wherein the display scan drive circuits 13R, 13L can be independent drive chips or circuits integrated in the panel and receive timing control signals transmitted by an integrated integrated circuit chip 15. Figure 1 The signal lines extending along the Y axis include display data lines 121, which are used to write display data. The three display data lines 121 can be connected to a multiplexer 17, and then connected to the outer lead bonding pad (OLB pad) 151 of the integrated circuit chip 15.

[0003] like Figure 1 As shown, the size of the integrated integrated circuit chip 15 in the X-axis direction is smaller than the display active area 101 of the integrated panel 10. Therefore, the display data lines 121 of the display active area 101 must be wound before they can be connected to the external pins 151 of the integrated integrated circuit chip 15. The size of the area required for winding is limited by the minimum line width and line spacing of the display panel process.

[0004] At Figure 1 On the integrated panel 10, the non-display area from the lower side of the display active area 101 to the lower edge of the integrated panel 10 is defined as a border area 102. The size of this border area 102 is related to the screen-to-body ratio of the display panel. In particular, mobile phone products require a higher screen-to-body ratio to improve the appearance of the product. Therefore, reducing the border area 102 becomes a very important product specification. However, the pin design of the existing integrated integrated circuit chip 15 is to set all the external pins 151 on the side of the integrated integrated circuit chip 15 close to the display active area 101. With this pin design, the border area 102 cannot be reduced because the area required for wire collection is large.

[0005] Therefore, the current design of integrated circuit chips cannot meet the demand for a high screen-to-body ratio of display panels, and needs to be improved. Summary of the invention

[0006] The main purpose of the present invention is to provide an integrated integrated circuit chip to solve the above-mentioned deficiencies in the prior art.

[0007] To achieve the aforementioned objectives, the present invention proposes an integrated integrated circuit chip for an integrated panel, the integrated integrated circuit chip comprising: a first long side; a second long side, opposite to the first long side; a first short side; a second short side, opposite to the first short side; and a surface surrounded by the first long side, the second long side, the first short side and the second short side, wherein at least one row of external pins is arranged on the surface, the at least one row of external pins having a plurality of spaced external pins, and the plurality of external pins are respectively arranged from a surface adjacent to a connection point between the second long side and the first short side and a surface adjacent to a connection point between the second long side and the second short side toward the first long side, gradually contracting to a surface close to the first long side, and then arranged along the first long side, and at least a portion of the plurality of external pins are used to transmit display and fingerprint signals.

[0008] The above summary and the following detailed description are exemplary in nature and are intended to further illustrate the claims of the present invention. Other objects and advantages of the present invention will be described in the subsequent description and drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0061] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the implementation methods of the present invention and are not used to limit the present invention.

[0062] Figure 2AThe integrated panel 20 of one embodiment of the present invention is shown. The integrated panel 20 has an active display area 201 and a non-display border area 202. An integrated integrated circuit chip 70 is disposed in the border area 202. The integrated integrated circuit chip 70 has a first long side 71, a second long side 74 facing the first long side 71, a first short side 72, a second short side 73 facing the first short side 72, and a surface 75, wherein the surface 75 refers to a side of the integrated integrated circuit chip 70 facing the integrated panel 20. The surface 75 is surrounded by the first long side 71, the second long side 74, the first short side 72 and the second short side 73, and a plurality of external pins 61 are disposed on the surface. Display scanning and fingerprint driving circuits 23L and 23R are disposed on the left and right sides of the active display area 201, respectively, to drive the scanning line 203 and the control signals required for fingerprint sensing (see Figure 2B The reset signal FP-reset and the selection signal FP-select) are received, and the timing control signal transmitted by the integrated circuit chip 70 is received.

[0063] Please refer to Figure 2A and 2B is a circuit diagram of an integrated panel 20 . The integrated panel 20 has a fingerprint sensor 26 built into the display panel, so that the RGB sub-pixels and the fingerprint sensor 26 form a pixel unit 21 . In the present embodiment, the plurality of circuit traces 22 extending along the Y axis from the display active region 201 include a display data line 221 and a display data and fingerprint data multiplexing line 223. The display data line 221 is used to write display data, and the display data and fingerprint data multiplexing line 223 uses a time-sharing method to write display data and read fingerprint data. The plurality of circuit traces 22 extend out of the display active region 201 toward the first long side 71 of the integrated integrated circuit chip 70, are arranged in the boundary region 202 through a plurality of multiplexers 27, and are connected to the plurality of external pins 61 toward the first long side 71, the first short side 72, and the second short side 73 of the integrated integrated circuit chip 70. In the present embodiment, every two display data lines 221 and one display data and fingerprint data multiplexing line 223 are connected to a multiplexer 27, and then connected to the external pins 61 of the integrated integrated circuit chip 70.

[0064] like Figure 2BAs shown, since the present embodiment uses the display data and fingerprint data multiplexing line 223 to multiplex the display data and fingerprint data on the same circuit trace 22, the integrated integrated circuit chip 70 includes a corresponding switch 51 to connect the display data and fingerprint data multiplexing line 223 to the display driving circuit 52 and the fingerprint sensing circuit 53 in the integrated integrated circuit chip 70 in a time-sharing manner. In addition, optionally, the present embodiment further includes a common electrode and a touch sensing circuit 54, and the plurality of circuit traces 22 further include a touch sensing line 541. The common electrode and the touch sensing circuit 54 are connected to the common electrode of the integrated panel 20 via the touch sensing line 541 to provide a touch sensing function, wherein the cutting of the common electrode as a touch sensor is known to those skilled in the art, so it will not be repeated here, and the aforementioned touch sensing, display driving and fingerprint reading are performed in a time-sharing manner. In the embodiment of the present invention, the display and the fingerprint sensor may be integrated into the panel, or the display, the fingerprint sensor and the touch sensing may be integrated into the panel. The integrated panel in the embodiment of the present invention may also be referred to as an embedded fingerprint recognition display panel or an under-screen fingerprint recognition display panel.

[0065] At least one external pin row 60 is disposed on the surface 75 of the integrated integrated circuit chip 70. The at least one external pin row 60 may be a single external pin row or a plurality of external pin rows. Figure 2A The embodiment shows that the external pins 61 on the surface 75 of the integrated integrated circuit chip 70 are arranged into two rows of external pin rows 60, each external pin row 60 has a plurality of external pins 61 arranged at intervals, and any two adjacent external pin rows 60 extend while maintaining a distance, and the plurality of external pins 61 of each external pin row 60 are respectively arranged from the surface 75 adjacent to the connection between the second long side 74 and the first short side 72 and the surface 75 adjacent to the connection between the second long side 74 and the second short side 73 toward the first long side 71, gradually shrinking to the surface 75 close to the first long side 71, and then arranged along the first long side 71, and at least a portion of the plurality of external pins 61 are used to transmit display and fingerprint signals, or to transmit display, fingerprint and touch signals.

[0066] The pin configuration of the external pin 61 can effectively utilize the area near the two short sides 72, 73 of the integrated integrated circuit chip 70, and can achieve the maximum overlap between the area required for the circuit trace 22 and the integrated integrated circuit chip 70, thereby effectively reducing the border area 202 and meeting the high screen-to-body ratio requirement of the display panel.

[0067] In addition, although two rows of external pins are used for illustration in the embodiments of the present invention, it is understandable that in some embodiments, there may be a single row of external pins or three or more rows of external pins. As long as the multiple external pins of the external pin row are arranged in accordance with the present invention to extend from one side of the chip to the other side in a gradually contracting and progressive manner, the non-display area can be effectively utilized to achieve effects such as reducing and narrowing the border, and the content disclosed in the embodiments is not limited to the contents disclosed in the embodiments.

[0068] Figure 3A The integrated panel 30 of another embodiment of the present invention is shown. The integrated panel 30 has an active display area 301 and a non-display border area 302. An integrated integrated circuit chip 70 is disposed in the border area 302. The integrated integrated circuit chip 70 has a first long side 71, a second long side 74 facing the first long side 71, a first short side 72, a second short side 73 facing the first short side 72, and a surface 75, wherein the surface 75 refers to a side of the integrated integrated circuit chip 70 facing the integrated panel 30. The surface 75 is surrounded by the first long side 71, the second long side 74, the first short side 72 and the second short side 73, and a plurality of external pins 61 are disposed on the surface. Display scanning and fingerprint driving circuits 33L and 33R are disposed on the left and right sides of the active display area 301, respectively, to drive the scanning line 303 and the control signals required for fingerprint sensing (see Figure 3B The reset signal FP-reset and the selection signal FP-select) are received, and the timing control signal transmitted by the integrated circuit chip 70 is received.

[0069] Please refer to Figure 3A and 3B 3 is a circuit diagram of an integrated panel 30. The integrated panel 30 has a fingerprint sensor 36 built into the display panel, so that the RGB sub-pixels and the fingerprint sensor 36 form a pixel unit 31. In this embodiment, the multiple circuit traces 32 extending along the Y axis of the display active area 301 include a display data line 321 and a display data and fingerprint data multiplexing line 323. The display data line 321 is used to write display data. The display data and fingerprint data multiplexing line 323 uses a time-sharing method to write display data and read fingerprint data. The multiple circuit traces 32 extend out of the display active area 301 toward the first long side 71 of the integrated integrated circuit chip 70, are arranged in the boundary area 302 and are connected to the multiple external pins 61 toward the first long side 71, the first short side 72 and the second short side 73 of the integrated integrated circuit chip 70.

[0070] like Figure 3BAs shown, since the present embodiment uses the display data and fingerprint data multiplexing line 323 to multiplex the display data and fingerprint data on the same circuit trace 32, the integrated integrated circuit chip 70 includes a corresponding switch 51, wherein the display data line 321 for display driving is directly connected to the display driving circuit 52 via the external pin 61, and the display data and fingerprint data multiplexing line 323 is connected to the switch 51, so as to connect the display data and fingerprint data multiplexing line 323 to the display driving circuit 52 in the display stage, and connect the display data and fingerprint data multiplexing line 323 to the fingerprint sensing circuit 53 in the fingerprint reading stage. In addition, optionally, the present embodiment further includes a common electrode and a touch sensing circuit 54, and the plurality of circuit traces 32 further include a touch sensing line 541, and the common electrode and the touch sensing circuit 54 are connected to the common electrode of the integrated panel 30 via the touch sensing line 541 to provide a touch sensing function, wherein the cutting of the common electrode as a touch sensor is known to those skilled in the art, so it will not be repeated here, and the aforementioned touch sensing, display driving and fingerprint reading are performed separately.

[0071] Please refer to Figure 3A As shown, the external pins 61 on the surface 75 of the integrated integrated circuit chip 70 are arranged into a plurality of external pin rows 60. In this embodiment, two external pin rows 60 are shown, each external pin row 60 has a plurality of external pins 61 arranged at intervals, and a distance is maintained between any two adjacent external pin rows 60. The plurality of external pins 61 of each external pin row 60 are arranged from the surface 75 adjacent to the connection between the second long side 74 and the first short side 72 and the surface 75 adjacent to the connection between the second long side 74 and the second short side 73 toward the first long side 71, gradually shrinking to the surface 75 close to the first long side 71, and then arranged along the first long side 71. The plurality of external pins 61 are used to transmit display and fingerprint signals, or to transmit display, fingerprint and touch signals.

[0072] The pin configuration of the external pin 61 can effectively utilize the areas near the two short sides 72, 73 of the integrated integrated circuit chip 70, and can achieve the maximum overlap between the area required for the circuit trace 32 and the integrated integrated circuit chip 70, thereby effectively reducing the border area 302 and meeting the high screen-to-body ratio requirement of the display panel.

[0073] Figure 4AThe integrated panel 40 of another embodiment of the present invention is shown. The integrated panel 40 has an active display area 401 and a non-display border area 402. An integrated integrated circuit chip 70 is disposed in the border area 402. The integrated integrated circuit chip 70 has a first long side 71, a second long side 74 opposite to the first long side 71, a first short side 72, a second short side 73 opposite to the first short side 72, and a surface 75, wherein the surface 75 refers to a side of the integrated integrated circuit chip 70 facing the integrated panel 40. The surface 75 is surrounded by the first long side 71, the second long side 74, the first short side 72 and the second short side 73, and a plurality of external pins 61 are disposed on the surface. Display scanning and fingerprint driving circuits 43L and 43R are disposed on the left and right sides of the active display area 401, respectively, to drive the scanning line 403 and the control signals required for fingerprint sensing (see Figure 4B The reset signal FP-reset and the selection signal FP-select) are received, and the timing control signal transmitted by the integrated circuit chip 70 is received.

[0074] Please refer to Figure 4A and 4B FIG. 4 is a circuit diagram of an integrated panel 40. The integrated panel 40 has a fingerprint sensor 46 built into the display panel, so that the RGB sub-pixels and the fingerprint sensor 46 form a pixel unit 41. In this embodiment, the fingerprint data and the display data do not share lines. The multiple circuit traces 42 extending along the Y axis in the display active area 401 include a display data line 421 and a fingerprint data line 423. The display data line 421 is used to write display data, and the fingerprint data line 423 is used to read fingerprint data. The multiple circuit traces 42 extend out of the display active area 401 toward the first long side 71 of the integrated integrated circuit chip 70, and are arranged in the boundary area 402 through multiple multiplexers 47 and connected to the multiple external pins 61 toward the first long side 71, the first short side 72 and the second short side 73 of the integrated integrated circuit chip 70. In this embodiment, every three display data lines 421 and one fingerprint data line 423 are connected to a multiplexer 47, and then connected to the external pins 61 of the integrated integrated circuit chip 70.

[0075] like Figure 4BThe integrated integrated circuit chip 70 includes a switch 51 to switch the display data line 421 to the display driving circuit 52, and to switch the fingerprint data line 423 to the fingerprint sensing circuit 53. In addition, optionally, the present embodiment further includes a common electrode and a touch sensing circuit 54, and the plurality of circuit traces 42 further include a touch sensing line 541. The common electrode and the touch sensing circuit 54 are connected to the common electrode of the integrated panel 40 via the touch sensing line 541 to provide a touch sensing function, wherein the cutting of the common electrode as a touch sensor is known to those skilled in the art, so it will not be repeated here, and the aforementioned touch sensing, display driving and fingerprint reading are performed simultaneously.

[0076] Please refer to Figure 4A As shown, the external pins 61 on the surface 75 of the integrated integrated circuit chip 70 are arranged into a plurality of external pin rows 60. In this embodiment, two external pin rows 60 are shown, each external pin row 60 has a plurality of external pins 61 arranged at intervals, and a distance is maintained between any two adjacent external pin rows 60. The plurality of external pins 61 of each external pin row 60 are arranged from the surface 75 adjacent to the connection between the second long side 74 and the first short side 72 and the surface 75 adjacent to the connection between the second long side 74 and the second short side 73 toward the first long side 71, gradually shrinking to the surface 75 close to the first long side 71, and then arranged along the first long side 71. The plurality of external pins 61 are used to transmit display and fingerprint signals, or to transmit display, fingerprint and touch signals.

[0077] With the pin configuration of the external pin 61 in the above-mentioned embodiment of the present invention, the area near the two short sides 72, 73 of the integrated integrated circuit chip 70 can be effectively used, and the maximum overlap between the area required for the collection of the circuit trace 42 and the integrated integrated circuit chip 70 can be achieved, thereby effectively reducing the border area 402 and meeting the high screen-to-body ratio requirement of the display panel.

[0078] Figure 5AThe external pin arrangement of an integrated integrated circuit chip according to an embodiment of the present invention is shown. In this embodiment, two external pin rows 60 are arranged on the surface 75 of the integrated integrated circuit chip 70. As shown in the figure, the plurality of external pins 61 of each external pin row 60 are arranged from the surface 75 adjacent to the connection between the second long side 74 and the first short side 72 to the first long side 71 and gradually shrink to the surface 75 close to the first long side 71, so that the arrangement direction of the plurality of external pins 61 and the first short side 72 have a first angle A1; the plurality of external pins 61 of each external pin row 60 are arranged from the surface 75 adjacent to the connection between the second long side 74 and the second short side 73 to the first long side 71 and gradually shrink to the surface 75 close to the first long side 71, so that the arrangement direction of the plurality of external pins 61 and the second short side 73 have a second angle A2. In this embodiment, the first angle A1 is equal to the second angle A2. In other embodiments, the first angle A1 may not be equal to the second angle A2. It can be seen from this that the plurality of external pins 61 of each external pin row 60 are arranged to form an upper base and two sides of an isosceles trapezoid.

[0079] In addition, each external pin 61 is a rectangle, and the length of the rectangle is perpendicular to the second long side 74. The multiple external pins 61 of an external pin row 601 (such as the external pin 611 in the figure) are arranged to be offset from the corresponding multiple external pins 61 of the adjacent external pin row 602 (such as the external pin 612 in the figure), that is, the external pins 611 and the external pins 612 are offset in the Y-axis direction instead of completely overlapping, so as to facilitate the layout and connection of the circuit traces 22, 32, 42.

[0080] Figure 5B The external pin arrangement of the integrated integrated circuit chip of another embodiment of the present invention is shown. This embodiment is similar to Figure 5A The embodiment of the present invention is different in that: the length of the rectangle of each external pin 61 of the external pin row 60 arranged along the first long side 71 is perpendicular to the second long side 74; the length of the rectangle of each external pin 61 of the external pin row 60 (such as the external pin 613 in the figure) arranged from the surface 75 adjacent to the connection between the second long side 74 and the first short side 72 to the first long side 71 and gradually shrinking to the surface 75 close to the first long side 71 is inclined toward the first short side 72 and forms a third angle B1 less than or equal to 90 degrees with the second long side 74; the length of the rectangle of each external pin 61 of the external pin row 60 (such as the external pin 614 in the figure) arranged from the surface 75 adjacent to the connection between the second long side 74 and the second short side 73 to the first long side 71 and gradually shrinking to the surface 75 close to the first long side 71 is inclined toward the second short side 73 and forms a fourth angle B2 less than or equal to 90 degrees with the second long side 74.

[0081] Further, a plurality of third angles B1 formed by the plurality of external pins 61 of the external pin row 60 arranged on the surface 75 adjacent to the connection between the second long side 74 and the first short side 72 and gradually contracting toward the first long side 71 to the surface 75 close to the first long side 71 and the second long side 74 gradually increase until they are equal to 90 degrees (that is, the external pins 61 arranged along the first long side 71 with the length of the rectangle being perpendicular to the second long side 74); similarly, a plurality of fourth angles B2 formed by the plurality of external pins 61 of the external pin row 60 arranged on the surface 75 adjacent to the connection between the second long side 74 and the second short side 73 and gradually contracting toward the first long side 71 to the surface 75 close to the first long side 71 and the second long side 74 gradually increase until they are equal to 90 degrees (that is, the external pins 61 arranged along the first long side 71 with the length of the rectangle being perpendicular to the second long side 74). Thus, the external pins 61 on the left and right sides of the integrated integrated circuit chip 70 are further rotated outwardly in the X-axis direction. Since the circuit traces 22, 32, 42 are also connected to the display active areas 201, 301, 401 by the external pins 61, the angle rotation of the external pins 61 can further reduce the area required for the wire collection. In one embodiment, the gradual increase of the third angle B1 can correspond to the gradual increase of the fourth angle B2.

[0082] Figure 5C The external pin arrangement of the integrated integrated circuit chip of another embodiment of the present invention is shown. This embodiment is similar to Figure 5A The embodiment of the present invention is different in that three external pin rows 60 are disposed on the surface 75 of the integrated integrated circuit chip 70. Therefore, more external pins 61 can be disposed on the surface 75 of the integrated integrated circuit chip 70 to be suitable for applications with a large number of circuit traces 22, 32, 42, such as higher resolution, or applications that integrate display, fingerprint and touch simultaneously, or applications that do not use a multiplexer. Figure 3A In the above embodiments, the two ends of the outer pin row are respectively arranged on the surface adjacent to the connection between the first short side and the first long side and the surface adjacent to the connection between the second short side and the first long side. However, in other embodiments, the two ends of the outer pin row can also be arranged slightly away from the first long side and extend toward the second long side, so that the area near the two short sides can be effectively used to achieve the maximum overlap between the area required for the circuit routing and the integrated integrated circuit chip, thereby effectively reducing and narrowing the boundary area, thereby meeting the demand for a high screen-to-body ratio of the display panel.

[0083] Figure 6 The mobile device of the present invention including an integrated integrated circuit chip is illustrated, wherein the mobile device is, for example, a mobile phone 61. Due to the use of the aforementioned integrated integrated circuit chip 70, the border area 202, 302, 402 can be effectively reduced to meet the demand for a high screen-to-body ratio of the display panel of the mobile device.

[0084] The above embodiments are merely examples for the convenience of explanation. The scope of rights claimed by the present invention shall be based on the claims, and is not limited to the above embodiments.
