Referring to
The touch control electrode layer 32 includes a plurality of touch control electrodes 22 insulated from each other. The touch control electrodes 22 are electrically connected to a driving circuit 27 by a plurality of touch control lines 24. The touch control lines 24 formed in two adjacent touch control electrodes 22 are electrically connected to each other by at least one bridge 26.
The touch control lines 24 and the touch control electrodes 22 are formed in a same layer. The bridge 26 and the touch control electrodes 22 are formed in different layers
Further, the touch control lines 24 and the touch control electrodes 22 formed in the touch control electrode layer 32 have two advantages: 1. the touch control lines 24 and the touch control electrodes 22 are formed by one light cover process to avoid forming the touch control lines by another process; 2. the touch control lines 24 and the touch control electrodes 22 are directly electrically connected to each other without being electrically connected by other appropriative via holes to simplify process and structure of the array substrate 31.
Because each touch control line 24 is electrically connected to one touch control electrode 22 to transfer signal of the touch control electrode 22 to the driving circuit 27. In order to avoid the touch control lines 24 and the touch control electrodes 22 from being formed in a same layer to electrically connect to each other, the bridges 26 are formed to avoid shorts occurring among the touch control electrodes 22.
A plurality of interspaces 34 is defined in the touch control electrodes 22. Edges of the touch control electrodes 22 are connected. The touch control lines 24 are formed in the interspaces 34 of the touch control electrodes 22.
The touch control lines 24 of each of the touch control electrodes 22 include a first line 241 electrically connected to the touch control electrode 22. The touch control lines 24 of each of the touch control electrodes 22 formed near the driving circuit 27 further include a second line 242 insulating with the touch control electrode 22. The second lines 242 are connected to the first lines 241 corresponding to the second lines 242 by the bridges 26.
By the interspaces 34 of the touch control electrodes 22, the touch control lines 24 and the touch control electrodes 22 can be formed in a same layer. In order to make the touch control electrodes 22 and the touch control lines 24 formed in a same layer and shorts not occurred among the touch control electrodes 22, structures of the touch control electrodes 22 are not limited to the above.
Further, the touch control electrodes 22 include a plurality of touch control ends 22a. The first lines 241 of the touch control lines 24 are electrically connected to the touch control electrodes 22 by the touch control ends 22a. The touch control ends 22a are defined as contacting ends between the touch control electrodes 22 and the touch control lines 24. When the touch control electrodes 22 and the touch control lines 24 are not contacted to each other, the touch control ends 22a do not exist.
In order to insure shorts not occurred among the touch control electrodes 22, each of the touch control electrodes 22 is electrically connected to the touch control lines 24 by n touch control ends 22a, the n is an integer and is greater than or equal to 1. Each of the touch control electrodes 22 is electrically connected to the driving circuit 27 by n touch control lines 24.
One touch control line is defined from one touch control end to the driving circuit. When one touch control electrode 22 is electrically connected to the driving circuit 27 by n touch control lines, the number of the touch control ends 22a of one touch control electrode 22 is n.
The array substrate 31 includes an insulating layer 25. The insulating layer includes a plurality of lead via holes 25a. The lead via holes 25a are electrically connected to the touch control electrodes 22 corresponding to the lead via holes 25. The lead via holes 25a have a changing lines function between the touch control electrodes 22 and the bridge 26.
The insulating layer 25 can be an existing structure of the array structure. The lead via holes 25a can be formed in a patterned process of the insulating layer 25 to avoid other process, so it is easily to change lines by the lead via holes 25a.
The insulating layer 25 is formed between the base substrate 21 and the touch control electrode layer 32. The base substrate includes a plurality of pixel units 33. The pixel units 33 include a plurality of thin film transistors 211. The bridges 26 and gate electrodes 2113 are formed in a same layer. The bridges 26 and the gate electrodes 2113 are formed by one light cover process and without other process to form the bridges 26.
The array substrate 31 includes a display area and a non-display area. The pixel units 33 are defined in the display area of the array substrate 31. The pixel units 33 include data lines and scanning lines formed crosswise and thin film transistors. Each thin film transistor includes a polycrystalline silicon layer, a gate insulating layer, a source and drain electrode and a gate electrode. Because the touch control lines are needed for transferring signals, the bridges 26 are made of metal. The bridges 26 can be made of metal formed in a layer of the gate electrode 2113 and the source and drain electrode 2112 of the thin film transistor.
In one embodiment, referring to
The pixel electrode lines 28 of the array substrate 31 are electrically connected to the source and drain electrodes to receive data signals and to control displays.
Because the touch control structure of the present disclosure is formed on the array substrate 31, the array substrate 31 is an embedded touch control display panel.
The pixel electrode lines 28 are electrically connected to the touch control electrodes 22 by the lead via holes 25a. The touch control lines 22 are not connected between the touch control electrodes 24. When the touch control signals need to be transferred, the bridges 26 can be used for transfer the touch control signals.
The pixel electrode lines 28 which are the bridges 26 are electrically connected to the touch control lines 22 by the lead via holes 25a.
The insulating layer 25 is formed between the base substrate 21 and the touch control electrode layer 32. The base substrate 21 includes a plurality of pixel units 33. The pixel units 33 include a plurality of thin film transistors 211. The bridges 26 and source and drain electrodes 2112 of the thin film transistor 211 are formed in a same layer. The bridges 26 and source and drain electrodes 2112 of the thin film transistor 211 can be formed by a same light cover process to simplify a process for manufacturing the array substrate 31.
The present disclosure also provides a display device. The array substrate 31 is used in the display device. Because a working principle of the display device is similar to a working principle of the array substrate 31, the working principle of the display device makes reference to the working principle of the array substrate.
The beneficial effect of this invention is: an array substrate is provided, touch control electrode lines are changed by public electrode lines to avoid separate preparations of touch control lines, buffer layers, and touch control via holes, to avoid two light cover processes, and to reduce costs and time for manufacturing the array substrate.
