The shield ring may be electrically insulated from the first conductive pattern layer by a crossover, as necessary.
A specific structure of the shield ring of the embodiment of the present disclosure will be described in detail below with reference to fig. 2 to 6.
Fig. 2 is a schematic cross-sectional view illustrating an array substrate including a shield ring according to a first embodiment of the present disclosure.
Referring to fig. 2, the array substrate 100 according to an embodiment of the present disclosure mainly includes a base substrate 101, a gate pattern layer 102 sequentially formed on the base substrate 101, a gate insulating layer 103 covering the gate pattern layer 102, an active pattern layer 104 formed on the gate insulating layer 103, a source electrode layer 105S and a drain electrode layer 105D (i.e., source/drain electrode layers 105S \105D) respectively contacting the active pattern layer 104 and partially covering the gate insulating layer 103, and a planarization layer 106. The array substrate 100 further includes a light emitting display device formed on the planarization layer 106, wherein the light emitting display device includes a cathode layer 109 serving as a touch electrode, an anode layer 107, and an organic light emitting layer 108 disposed between the cathode layer 109 and the anode layer 107, and an encapsulation layer 110. In addition, a pixel defining layer PDL is disposed between the cathode layer 109 and the anode layer 107.
In the embodiment shown in fig. 2, the shielding ring 200 is disposed in the peripheral region of the array substrate 100 and is formed around the cathode 109. Only the shield ring 200 disposed in the left region of the array substrate 100 is shown in the cross-sectional view of fig. 2, as shown in fig. 1.
In the present embodiment, the shield ring 200 is formed in the same layer as the cathode layer 109 and is electrically insulated from the cathode layer 109.
In one embodiment, the shield ring 200 and the cathode layer 109, which are electrically insulated from each other, may be formed by depositing an electrode material layer on the pixel defining layer PDL and the organic light emitting layer 108, and then by performing, for example, a patterning process on the electrode material layer.
If the shield ring 200 meets the external lead of the cathode layer 109 on the same layer, the shield ring 200 may cross over the external lead of the cathode layer 109 by means of a crossover, i.e., the shield ring 200 may cross over by means of other conductive patterns located on different layers (e.g., a gate metal pattern on the gate insulating layer 103, or an anode metal pattern on the planarization layer 106, etc.). Accordingly, the shield ring 200 can be electrically insulated from the cathode layer 109.
Fig. 3 is a schematic cross-sectional view illustrating an array substrate including a shield ring according to a second embodiment of the present disclosure.
Referring to fig. 3, in the present embodiment, an array substrate 100-1 according to the present embodiment has a similar configuration to the array substrate 100 of the first embodiment except that an arrangement of a shield ring 200-1 is different from that of the shield ring 200 of the first embodiment, and the difference therebetween will be mainly described below.
In the present embodiment, the shield ring 200-1 is not formed in the same layer as the cathode layer 109, but is formed in the same layer as the anode layer 107 and is electrically insulated from the anode layer 107. The shield ring 200-1 is formed around the anode layer 107 in the peripheral region of the array substrate 100-1.
Similarly, in one embodiment, the shield ring 200-1 and the anode layer 107 may be formed to be electrically insulated from each other by depositing a layer of electrode material on the planarization layer 106, and then by subjecting the layer of electrode material to, for example, a patterning process.
The shield ring 200-1 may also be electrically isolated from the anode layer 107 by similar bridging, if desired.
In addition, the array substrate may include both the shield ring 200 formed in the same layer as the cathode layer 109 and electrically insulated from the cathode layer 109 and the shield ring 200-1 formed in the same layer as the anode layer 107 and electrically insulated from the anode layer 107. In this case, the shield ring 200 may be electrically connected to the shield ring 200-1 through a via hole formed in the pixel defining layer PDL. Therefore, the interference of the clock signal and the parasitic signal to the touch signal can be better shielded.
Fig. 4 is a schematic cross-sectional view illustrating an array substrate including a shield ring according to a third embodiment of the present disclosure.
Referring to fig. 4, in the present embodiment, an array substrate 100-2 according to the present embodiment has a similar configuration to the array substrate 100 of the first embodiment except that an arrangement of a shield ring 200-2 is different from that of the shield ring 200 of the first embodiment, and the difference therebetween will be mainly described below.

The shield ring 200-2 is formed around the source electrode 105S and the drain electrode 105D in the peripheral region of the array substrate 100-2.
Similarly, in one embodiment, the shield ring 200-2 and the source electrode 105S and the drain electrode 105D may be formed to be electrically insulated from each other by depositing a metal material layer on the gate insulating layer 103 and then by performing, for example, a patterning process on the metal material layer.
The shield ring 200-2 can also be electrically insulated from the source electrode 105S and the drain electrode 105D by a similar bridge connection manner, if necessary.
Fig. 5 is a schematic cross-sectional view illustrating an array substrate including a shield ring according to a fourth embodiment of the present disclosure.
Referring to fig. 5, the array substrate 100-3 according to the present embodiment has a similar configuration to the array substrate 100 of the first embodiment except for a shield ring, and differences therebetween will be mainly described below.

As shown in fig. 5, the shield ring 200 may be electrically connected to the shield ring 200-1 through a via H1 formed in the pixel defining layer PDL, and the shield ring 200-1 may be electrically connected to the shield ring 200-2 through a via H2 formed in the planarization layer 106. Accordingly, the shield ring 200-1, and the shield ring 200-2 are electrically connected.
Further, the formation methods of the shield ring 200, the shield ring 200-1, and the shield ring 200-2 may be similar to those described in the above embodiments, respectively.
Of course, it is understood that the shield ring 200, the shield ring 200-1 and the shield ring 200-2 may not be electrically connected to each other. Alternatively, two of the shield ring 200, the shield ring 200-1, and the shield ring 200-2 are electrically connected. For example, the shield ring 200 is electrically connected to the shield ring 200-1, or the shield ring 200-1 and the shield ring 200-2 are electrically connected.
Fig. 6 is a schematic cross-sectional view illustrating an array substrate including a shield ring according to a fifth embodiment of the present disclosure.
The array substrate 100-4 according to the present embodiment has a similar configuration to the array substrate 100 of the first embodiment except for the shield ring, and the difference therebetween will be mainly described below.
In the present embodiment, the shield ring includes a shield ring 200 formed in the same layer as the cathode layer 109 and electrically insulated from the cathode layer 109, a shield ring 200-1 formed in the same layer as the anode layer 107 and electrically insulated from the anode layer 107, a shield ring 200-2 formed in the same layer as the source electrode 105S and the drain electrode 105D and electrically insulated from the source electrode 105S and the drain electrode 105D, and a shield ring 200-3 formed in the same layer as the gate pattern layer 102 and electrically insulated from the gate pattern layer 102.
As shown in fig. 6, the shield ring 200 may be electrically connected to the shield ring 200-1 through a via H1 formed in the pixel defining layer PDL, the shield ring 200-1 may be electrically connected to the shield ring 200-2 through a via H2 formed in the planarization layer 106, and the shield ring 200-2 may be electrically connected to the shield ring 200-3 through a via H3 formed in the gate insulating layer 103. In this case, the shield ring 200-1, the shield ring 200-2, and the shield ring 200-3 can be electrically connected.
Also, the shield ring 200-1, the shield ring 200-2, and the shield ring 200-3 may not be electrically connected to each other. Alternatively, adjacent two of the shield rings 200, 200-1, 200-2, and 200-3 may be electrically connected.
An array substrate including a shield ring according to some embodiments of the present disclosure is illustrated in fig. 2 to 6, however, according to the present disclosure, the array substrate of the present disclosure is not limited only to the examples shown in fig. 2 to 6.
Fig. 7 is a partial schematic plan view illustrating a shield ring crossing a gate wiring electrically connected to a touch electrode by means of a crossover so as to be electrically insulated from the gate wiring according to an embodiment of the present disclosure.
In fig. 7, the cathode layer 109 of the light emitting display device is connected downward through the hollowed-out region T1 of the pixel defining layer PDL to be electrically connected to the underlying lateral anode metal layer (e.g., ITO/Ag/ITO layer), and then electrically connected to the gate wiring 400 formed on the substrate base plate 101 through the via hole T2 formed in the planarization layer 106 and the via hole T3 formed in the gate insulating layer 103.
In this case, for example, the shield ring 200-3 formed in the same layer as the gate pattern layer 102 and electrically insulated from the gate pattern layer 102 will encounter the gate wiring 400 when making a ring connection, and at this time, in order to achieve electrical insulation from the gate wiring 400, the shield ring 200-3 may be electrically connected in a closed ring by a jumper CL located in a different layer via a via T3 formed in the gate insulating layer 103.
In one embodiment, the jumper line CL may be a part of a source-drain electrode layer (which is electrically insulated from the source electrode 105S and the drain electrode 105D) formed on the gate insulating layer 103, or a part of an anode layer (which is electrically insulated from the anode layer 107) formed on the planarization layer 106. However, in the present disclosure, the type of the jumper line CL is not limited thereto as long as the shield ring can be electrically insulated from the conductive layers of the same layer (e.g., the cathode layer 109, the anode layer 107, the source electrode 105S and the drain electrode 105D, or the gate pattern layer 102, etc.).
In addition, embodiments of the present disclosure also provide an embedded touch display panel including the array substrate described above.
Since the shielding rings are arranged around the corresponding conductive pattern layers in the peripheral region of the array substrate, interference of clock signals and parasitic signals to touch signals can be effectively shielded, and thus touch sensitivity is improved.
