Detailed Description
The technical solutions in the embodiments of the present application will be described clearly and completely with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Referring to the array substrate 100 shown in fig. 1, the array substrate 100 includes a display area 10 and a non-display area 20. A plurality of pixel units 11 are provided in the display area 10. The non-display area 20 is located at the periphery of the display area 10. A plurality of function control points 21 are arranged in the non-display area 20 in series in sequence. The function control point 21 is configured to control the pixel unit 11 and provide a scan signal or a data signal to the pixel unit 11. It is understood that in some embodiments, due to the larger display area 10 or the larger number of pixel units 11 in the display area 10, the display area 10 may be divided into a plurality of pixel regions 101, and the pixel units 11 in each pixel region 101 are controlled by a set of the function control points 21.
Referring to fig. 2, each of the function control points 21 is connected in series through a TFT switch 30. That is, two adjacent function control points 21 are connected in series, and one TFT switch 30 is disposed in a series circuit between two adjacent function control points 21. It will be appreciated that when the number of function control points 21 is "N", there will be a number "N-1" of the TFT switches 30 connecting "N" of the function control points 21 in series. As can be seen from fig. 2, the TFT switches 30 are connected in parallel, and the TFT switches 30 connected in parallel are all connected to the switch control point 31.
With such a circuit structure design, the array substrate 100 can simultaneously turn on or off the TFT switches 30 connected in series between the function control points 21 by controlling the voltage at the switch control points 31. It is understood that when the TFT switches 30 are simultaneously turned on, the function control points 21 are connected in series. On the contrary, when the TFT switches 30 are turned off simultaneously, the function control points 21 are turned off independently. After the prior art array substrate is coated with gold paste to connect the originally independent function control points 21 in series, the series connection state between the function control points 21 is an irreversible state (unless expensive gold paste is cut off). And adopt this application array substrate 100's structure, then pass through switch control point 31 just can realize each series connection/disconnection state between the function control point 21 freely switches, has saved the use of golden glue simultaneously, has not only improved this application array substrate 100's electric compatibility ability, has still reduced manufacturing cost. Further, because bad defects such as glue break, spin coating and the like easily occur in the gold glue coating process, the array substrate 100 further improves the yield because the use of the gold glue is omitted.
It is understood that the TFT switch 30 can be fabricated together with the TFT structures in the pixel units 11 in the display area 10, and no additional process steps are required.
With continued reference to fig. 2, the function control points 21 include a first common electrode control point 211, a color control point 212, and a gate control point 213. Specifically, the number of the color control dots 212 should be at least three, that is, three colors of "RGB" commonly used in the liquid crystal field. Where "R" is a red control point 2121, "G" is a green control point 2122, and "B" is a blue control point 2123. Each of the color control points 212 is connected to a sub-pixel unit of a corresponding color in the display area 10. Taking the red control point 2121 as an example, the pixel unit 11 includes a red sub-pixel unit, and the red control point 2121 is connected to the signal electrodes of all red sub-pixel units in the corresponding pixel region 101.
It is understood that in some liquid crystal panels with more than three sub-pixel units or without "RGB" single arrangement, the color control points 212 can be correspondingly adjusted to more than three or corresponding matching in color. This is not a particular limitation of the present application.
The gate circuit control point 213 specifically includes an ST control point 2131, a CK control point 2132, and a VSS control point 2133, and the gate circuit control point 213 is connected to the scan electrode in the pixel unit 11 in the display area 10 to control the switching operation of the TFT in the pixel unit 11.
Further, a second common electrode control point 22 is disposed in the non-display area 20 of the array substrate 100. The second common electrode control point 22 and the first common electrode control point 211 cooperate to form an electric field between two sets of common electrodes in the liquid crystal panel.
The present application relates to a method for inspecting an array substrate, and the array substrate 100 is described herein. That is, the array substrate 100 is required to have a plurality of pixel units 11 in the display region 10 and a plurality of function control points 21 connected in series in sequence in the non-display region 20. The function control point 21 is configured to control the pixel unit 11 and provide a scan signal or a data signal to the pixel unit 11. The function control points 21 are connected in series through a TFT switch 30, the TFT switches 30 are connected in parallel, and the TFT switches 30 connected in parallel are connected to the switch control point 31. When the array substrate 100 is tested, because the TFT switch 30 exists, the TFT switch 30 needs to be turned off first, and then the structural layer corresponding to each of the functional control points 21 in the array substrate 100 is subjected to a defect check (on/off performance, etc.) and an electrical measurement.
It will be appreciated that turning off the TFT switch 30 can be achieved by powering off the switch control point 31. However, since the switch control point 31 is in the floating state when no voltage is applied, it is generally considered that the voltage of each of the TFT switches 30 connected in parallel at this time is ≈ 0V. The TFT switch 30 in the 0V state is actually in a slightly on state, and a leakage current occurs. For this purpose, the TFT switches 30 are completely turned off, and the functional control points 21 are completely disconnected and independent from each other. A first voltage needs to be applied to the switch control point. The first voltage is typically a low voltage and may take the value "-5V" to ensure that the TFT switch 30 is fully closed. In the electrical measurement, different potentials can be applied to the function control points 21 without mutual interference. It will be appreciated that the application of the potential at this point may be accomplished by way of a needle insertion.
The present application also relates to a liquid crystal panel 300. The liquid crystal panel 300 includes a color substrate 200 and the array substrate 100. Liquid crystal is filled between the color substrate 200 and the array substrate 100. Referring to fig. 3, a first electrical region 201 and a second electrical region 202, which are insulated from each other, are cut out of the color substrate 200 by laser. After the color substrate 200 and the array substrate 100 are aligned, it is required to ensure that the projection of at least one of the function control points 21 on the color substrate 200 is located within the first electrical region 201. While the projections of the switch control point 31 and the second common electrode control point 22 on the color substrate 20 are both located within the second electrical zone 202. The color substrate 200 and the array substrate 100 are electrically connected. Specifically, the function control point 21 projected in the first electrical area 201 is electrically connected to the first electrical area 201, and the second common electrode control point 22 and the switch control point 31 are electrically connected to the second electrical area 202, respectively. It will be appreciated that the electrical connection here may be achieved by gold glue.
Since the conduction between the function control points 21 on the array substrate 100 can be controlled by the switch control points 31, only one function control point 21 is needed to correspond to and electrically connect with the first electrical region 201, and the same voltage can be provided to all the function control points 21 on the array substrate 100. That is, in the liquid crystal panel 300, the electric connection between the array substrate 100 and the color substrate 200 only needs three points for electric connection.
When performing liquid crystal alignment on the liquid crystal panel 300 described in the present application, the following steps are required:
a second voltage is applied to the second electrical region 202 by the second common electrode control point 22 so that the second electrical region 202 is in a potential state of the second voltage, it being understood that the switch control point 31 and the second common electrode control point 22 are both in the same potential state. The switch control points 31 need to be able to open the TFT switches 30 simultaneously in the second voltage state so that the respective function control points 21 are in series. Thus, the second voltage needs to be higher than the turn-on voltage of the TFT switch 30;
by applying a third voltage to the first electrical region 201 via the first common electrode control point 211, the functional control point 21 electrically connected to the first electrical region 201 and to it is brought into a potential state of the third voltage. Due to the serial connection relationship among the function control points 21, the pixel units 11 in the array substrate 100 are all in the potential state of the third voltage;
a voltage difference between the second voltage and the third voltage is set, so that an electric field required for liquid crystal alignment is formed between the common electrode on the color substrate 200 and the common electrode on the array substrate 100, and the liquid crystal panel 300 can perform liquid crystal alignment.
It can be understood that, in an embodiment, the second voltage is set to be 15V, and the third voltage is set to be 0V, so that the liquid crystal alignment operation can be better performed.
In one embodiment, the projections of all the function control points 21 on the color substrate 200 are located within the first electrical area 201, and an operator can freely select the function control points 21 electrically connected with the first electrical area 201 according to different environmental requirements.
It is understood that when a plurality of pixel regions 101 are disposed in the array substrate 100, a plurality of first electrical regions 201 may also be correspondingly disposed on the color substrate 200.
The liquid crystal panel 300 of the present application has the ability to freely control the electrical connection state of the functional control point 21 by using the array substrate 100 of the present application. Meanwhile, the use of gold glue is omitted, so that the manufacturing cost is reduced, and the yield is improved.
The above-described embodiments do not limit the scope of the present invention. Any modification, equivalent replacement, and improvement made within the spirit and principle of the above-described embodiments should be included in the protection scope of the technical solution.
