FIG. 1E is a schematic cross-sectional view taken along section line A-A' in FIG. 1B.
Referring to fig. 1A to fig. 1E, the touch display panel 100 of the present embodiment includes a substrate 110 (shown in fig. 1E), a touch device 120, a buffer layer 150, and a display device 160. In the present embodiment, the substrate 110 may be a hard substrate or a flexible substrate with visible light transmittance, so that the light L emitted by the display device 160 can pass through. For example, the material of the hard substrate is glass or other hard material, and the flexible substrate material is Polyimide (PI), polycarbonate (PC), polyamide (PA), polyethylene terephthalate (polyethylene terephthalate; PET), polyethylene naphthalate (polyethylene naphthalate; PEN), polyethylene imine (PEI), polyurethane (PU), polydimethylsiloxane (PDMS), a gram pressure polymer is polymethyl methacrylate (PMMA), an ether polymer is polyether sulfone (PES) or polyether ether ketone (PEEK), a polyolefin (polyalkylene), a thin glass or other flexible material, but the present invention is not limited thereto.
The touch device 120 is disposed on the substrate 110. The touch device 120 includes a plurality of first touch lines 130, a plurality of second touch lines 140, and a first insulating layer 121. The first insulating layer 121 is located between the first touch circuit 130 and the second touch circuit 140 to electrically insulate the first touch circuit 130 and the second touch circuit 140 from each other. The first insulating layer 121 may be made of an inorganic material, and includes: silicon oxide (SiO) x ) Silicon nitride (SiN) x ) Silicon oxynitride (SiON), aluminum oxide (AlO) x ) Aluminum oxynitride (AlON) or the like. In other embodiments, the first insulating layer 121 may be made of an organic material, which includes: polyimide (PI), polycarbonate (PC), polyamide (PA), polyethylene terephthalate (polyethylene terephthalate; PET), polyethylene naphthalate (polyethylene naphthalate; PEN), polyethylenimine (PEI), polyurethane (PU), polydimethylsiloxane (PDMS), a pressure-sensitive polymer such as polymethyl methacrylate (PMMA), an ether polymer such as Polyethersulfone (PES) or Polyetheretherketone (PEEK), a polyolefin (polyalkylene) or the like, or other analogues or combinations thereof. In other possible embodiments, the organic material and the inorganic material may be alternately stacked to form the first insulating layer 121.
In the present embodiment, the first touch circuit 130 and the second touch circuit 140 are different conductive films, and the first touch circuit 130 is located between the second touch circuit 140 and the substrate 110. The first touch circuit 130 and the second touch circuit 140 are disposed across each other to form a plurality of sensing arrays. In other words, each sensing array may be a range surrounded by two adjacent first touch lines 130 and two adjacent second touch lines 140. The first touch circuit 130 and the second touch circuit 140 are adapted to sense an electrical change generated by a touch of a user. If a user touches the touch display panel 100, the electrical changes sensed by the first touch circuit 130 and the second touch circuit 140 in the corresponding sensing array can be detected and identified by a controller (not shown) connected to the touch device 120.
The display element 160 is disposed on the substrate 110, and a buffer layer 150 is disposed between the display element 160 and the touch element 120 for separating the touch element 120 and the display element 160. In this embodiment, the buffer layer 150 may be a dielectric layer covering the touch device 120. For example, the buffer layer 150 may be made of an inorganic material, which includes: silicon oxide (SiO) x ) Silicon nitride (SiN) x ) Silicon oxynitride (SiON), aluminum oxide (AlO) x ) Aluminum oxynitride (AlON) or the like. In other embodiments, the buffer layer 150 may be made of an organic material, which includes: polyimide (PI), polycarbonate (PC), polyamide (PA), polyethylene terephthalate (polyethylene terephthalate; PET), polyethylene naphthalate (polyethylene naphthalate; PEN), polyethylenimine (PEI), polyurethane (PU), polydimethylsiloxane (PDMS), a pressure-sensitive polymer such as polymethyl methacrylate (PMMA), an ether polymer such as Polyethersulfone (PES) or Polyetheretherketone (PEEK), a polyolefin (polyalkylene) or the like, or other analogues or combinations thereof. In other possible embodiments, the organic material and the inorganic material may be alternately stacked to form the buffer layer 150.
In this embodiment, the buffer layer 150 has a flat upper surface, for example, so that the display device 160 formed later can be fabricated on the flat upper surface. In addition, the buffer layer 150 may block permeation of oxygen and/or moisture. In detail, when the touch display panel 100 is a flexible touch display panel, the manufacturing of the flexible touch display panel is not only to overcome the manufacturing process problem of manufacturing the touch display panel with the flexible substrate, but also to increase the difficulty of the packaging process of the display element 160 due to the flexible substrate. For example, in a hard touch display panel, the penetration of air can be blocked by the hard substrate, which is beneficial to preventing moisture and oxygen in the air from damaging the display element 160. The barrier capability of the flexible substrate made of the aforementioned flexible material may not meet the gas barrier requirement of the display element 160 during the packaging process. At this time, the buffer layer 150 with the barrier function can prevent air from penetrating the flexible substrate to affect the display element 160. Furthermore, forming the buffer layer 150 between the touch device 120 and the display device 160 can reduce the interference (cross talk) between the display signal and the sensing signal, thereby improving the display and touch quality of the touch display panel 100 according to the embodiment of the invention.
The display element 160 includes a plurality of first display electrodes 161, a plurality of second display electrodes 162, a second insulating layer 164 (shown in fig. 1E), a plurality of light emitting diode dies 163, and a plurality of driving circuits 180. The second display electrode 162 and the first display electrode 161 are disposed across each other, and the second display electrode 162 and the first display electrode 161 are located between the led die 163 and the substrate 110. The second insulating layer 164 is disposed between the first display electrode 161 and the second display electrode 162 to electrically insulate the first display electrode 161 and the second display electrode 162 from each other. The driving circuit 180 may be electrically connected to the second display electrode 162 through the conductive via 166 penetrating the second insulating layer 164. The driving circuit 180 and the second display electrode 162 are the same layer, and the driving circuit 180 and the second display electrode 162 may have different extending directions and may be electrically connected to a driving chip (not shown) located on one side of the touch display panel 100.
In the present embodiment, the material or the forming manner of the second insulating layer 164 may be the same as or similar to that of the first insulating layer 121, but the present invention is not limited thereto. The materials of the first display electrode 161, the second display electrode 162 and the driving circuit 180 may be transparent conductive materials or opaque conductive materials. The transparent conductive material is, for example, indium Tin Oxide (ITO), indium zinc oxide (indium zinc oxide; IZO), or the like, and the opaque conductive material is, for example, a metal.
In the present embodiment, the first touch circuit 130 overlaps the first display electrode 161, and the second touch circuit 140 overlaps the second display electrode 162. The area of the first touch circuit 130 is smaller than or equal to the area of the first display electrode 161, and the area of the second touch circuit 140 is smaller than or equal to the area of the second display electrode 162. The touch device 120 and the display device 160 are integrated in the touch display panel 100, and the influence of the first touch circuit 130 or the second touch circuit 140 of the touch device 120 on the display quality can be reduced, and the space utilization of the touch display panel 100 can be improved in the layout design (layout).
In some embodiments, the first touch circuit 130 may also overlap the second display electrode 162, and the second touch circuit 140 may also overlap the first display electrode 161, where the area of the first touch circuit 130 is smaller than or equal to the area of the second display electrode 162, and the area of the first touch circuit 130 is smaller than or equal to the area of the second display electrode 162.
The display element 160 has a plurality of pixel units PU arranged in an array, and each pixel unit PU is composed of a corresponding first display electrode 161, a second display electrode 162, and a light emitting diode die 163. In the present embodiment, each pixel unit PU includes, for example, three light emitting diode dies 163R, 163G, 163B. The three light emitting diode dies 163R, 163G, 163B may emit light of different colors, but the present invention is not limited thereto. The led die 163 is, for example, a lateral type (lateral type) led die, and is electrically connected to the first display electrode 161 and the second display electrode 162 by flip-chip bonding. Each light emitting diode die 163 in the same pixel unit PU is electrically connected to a corresponding first display electrode 161, and the light emitting diode die 163 in the same pixel unit PU is electrically connected to the same second display electrode 162 through a corresponding conductive via 165.
In the present embodiment, the touch device 120 is disposed between the display device 160 and the substrate 110, and the touch display panel 100 may be a bottom emission (bottom emission) display panel. That is, the light L emitted from the light emitting diode die 163 may pass through the second insulating layer 164, the buffer layer 150, the first insulating layer 121, and the substrate 110 to the outside.
In the present embodiment, the first touch circuit 130 has a plurality of first annular circuits 133, the second touch circuit 140 has a plurality of second annular circuits 143, and the led die 163 is located in the region 133R surrounded by the corresponding first annular circuits 133. The second annular line 143 overlaps the plurality of first annular lines 133, and a width 143W of the second annular line 143 is greater than or equal to a width 133W of the first annular line 133. That is, the front projection of the first loop circuit 133 on the substrate 110 is within the range covered by the front projection of the second loop circuit 143 on the substrate 110. If the first touch circuit 130 is a sensing electrode and the second touch circuit 140 is a driving electrode, the interference of the first display electrode 161 and/or the second display electrode 162 to the first touch circuit 130 can be reduced by the second touch circuit 140. In this way, the interference of the display signal to the sensing signal can be reduced, so as to improve the touch quality of the touch display panel 100 according to the embodiment of the invention.
As shown in fig. 1E, in the present embodiment, the first ring-shaped circuit 133 may not overlap the led die 163. Therefore, the interference of the display signal to the sensing signal can be further reduced, and the touch quality of the touch display panel 100 can be further improved.
In the present embodiment, the width 133W of the first annular line 133 or the width 143W of the second annular line 143 is between 1.1 micrometers (μm) and 11 micrometers, and the width 143W of the second annular line 143 is greater than or equal to the width 133W of the first annular line 133.
In the present embodiment, the width 133RW of the region 133R surrounded by each first annular line 133 is between 5 μm and 100 μm, or the area of the region 133R surrounded by each first annular line 133 is between 25 square μm and 1000 square μm. In an embodiment, the light emitting diode die 163 corresponding to the region 133R surrounded by the first ring-shaped circuit 133 may be a micro light emitting diode (μled) die.
In this embodiment, the touch display panel 100 may further include a packaging layer 191, a reflective layer 192, and a protective layer 193 sequentially covering the display element 160.
