The application aims at the technical problem that the existing liquid crystal display panel adopting the FFS technology has voltage bias to cause display of residual images, and provides the liquid crystal display panel and the liquid crystal display device to relieve the technical problem.
As shown in fig. 1, an embodiment of the present application provides a liquid crystal display panel, where the liquid crystal display panel 1 includes:
a first substrate 11;
a second substrate 14 disposed opposite to the first substrate 11;
a liquid crystal layer 12 disposed between the first substrate 11 and the second substrate 14;
the liquid crystal display panel 1 includes a display region 161 and a non-display region 162 surrounding the display region 161, at least one of the first substrate 11 and the second substrate 14 is provided with a first electrode 15 and a second electrode 16 on a side close to the liquid crystal layer 12, at least a part of the first electrode 15 and at least a part of the second electrode 16 are respectively provided in the non-display region 162 on different sides of the display region 161 (for example, the first electrode 15 and the second electrode 16 are respectively provided in the non-display region on the left side of the display region 161 and the non-display region on the right side of the display region 161 in fig. 1), and the first electrode 15 and the second electrode 16 form an electric field in a horizontal direction when being energized.
The embodiment of the application provides a liquid crystal display panel, this liquid crystal display panel is through setting up first electrode and second electrode in one side that is close to the liquid crystal layer, make at least partial first electrode and second electrode set up respectively in different non-display areas, and first electrode and second electrode form the electric field of horizontal direction when circular telegram, then the free ion that is located the liquid crystal layer can be under the control of horizontal electric field, move to the first electrode and the second electrode of both sides, make free ion adsorb on first electrode and second electrode, then in the display process, because the free ion of liquid crystal layer is less, reduce the voltage difference that leads to because of ion adsorption, thereby reduce the possibility that shows the afterimage, improve display effect.
As shown in fig. 1, liquid crystal molecules are disposed in the liquid crystal layer 12, and a large number of free ions, specifically including negatively charged ions 121 and positively charged ions 122, exist between the liquid crystal molecules, and when displaying, these ions are attracted to the pixel electrode and the common electrode under the action of the electric fields of the pixel electrode and the common electrode, so that the display screen cannot be normally turned off, and a residual image appears. In the embodiment of the application, the first electrode and the second electrode are arranged to process free ions in the liquid crystal display panel, so that the problem of image retention is solved.
Specifically, fig. 1 shows a state in which the free ions in the liquid crystal display panel are not treated, that is, the first electrode and the second electrode in the liquid crystal display panel are not energized, and fig. 2 shows a state in which the free ions in the liquid crystal display panel are treated, that is, the first electrode and the second electrode in the liquid crystal display panel are energized. As can be seen from a comparison between fig. 1 and fig. 2, after the first electrode 15 and the second electrode 16 are powered on, the negatively charged ions 121 will be moved to the first electrode 15 by the electric field, and the positively charged ions 122 will be moved to the second electrode 16 by the electric field, so that the free ions in the display area are reduced, and the generation of afterimages is avoided when the liquid crystal display panel displays.
Specifically, the above-described embodiment has been described in detail by taking an example in which the potential of the first electrode is higher than the potential of the second electrode, and the following embodiment also describes an example in which the potential of the first electrode is higher than the potential of the second electrode.
Specifically, the electric fields generated by the pixel electrode and the common electrode in the liquid crystal display panel are mainly vertical electric fields, so that free ions generally move along the vertical direction and are kept in the display area, while the first electrode and the second electrode generate horizontal electric fields in the application, so that free particles move to the non-display area and are adsorbed on the first electrode and the second electrode, when the pixel electrode and the common electrode work, even if the vertical electric fields are generated, part of the free ions also move along the longitudinal direction and cannot move to the display area, and the number of the free ions in the display area is reduced.
Specifically, when the liquid crystal display panel displays, the electric fields of the pixel electrode and the common electrode may cause free ions to return to the display area, because the voltage is applied before the liquid crystal display panel is shipped or turned on or off, the free ions are moved to the first electrode and the second electrode of the non-display area, the time of one frame during displaying is short, the free ions cannot be moved to the display area completely, the voltage directions and the sizes of different frames are different, the free ions are further caused to be unable to move to the display area and adsorbed on the pixel electrode and the common electrode, so that the free ions in the display area are reduced on the whole, and the technical problem of residual images of the liquid crystal display panel is improved or even eliminated.
In an embodiment, as shown in fig. 3, the non-display area 162 includes a first non-display area 162a, a second non-display area 162b, a third non-display area 162c and a fourth non-display area 162d located around the display area 161, the first non-display area 162a is disposed opposite to the third non-display area 162c, the second non-display area 162b is disposed opposite to the fourth non-display area 162d, the first electrode is disposed in the first non-display area, and the second electrode is disposed in the third non-display area; or the first electrode is arranged in the second non-display area, and the second electrode is arranged in the fourth non-display area. The first electrode and the second electrode are arranged in the non-display area which is oppositely arranged, so that an electric field in the horizontal direction is formed between the first electrode and the third electrode, and free ions in the display area can move from the display area to the non-display area under the action of the electric field, so that the free ions in the display area are reduced, and the problem of display afterimage is solved.
Specifically, for the non-display areas located around the display area, each non-display area may have an intersection area, and the intersection area may be divided into an area in a certain non-display area or an area in two non-display areas, and the intersection area is taken as an area in a certain non-display area in fig. 3 for example, the first non-display area 162a in fig. 1 includes an intersection area of the first non-display area and the fourth non-display area, and the fourth non-display area 162d does not include an intersection area of the first non-display area and the fourth non-display area.
In one embodiment, as shown in fig. 3, the first electrode 15 is disposed in the first non-display region 162a and extends to the fourth non-display region 162d, and the second electrode 16 is disposed in the second non-display region 162b and extends to the third non-display region 162 c. In order to adsorb free ions in each area of the display area and reduce the number of the free ions in the display area, the first electrode can be arranged in the first non-display area and the fourth non-display area, the second electrode is arranged in the second non-display area and the third non-display area, so that the non-display areas around the display area are provided with electrodes, an electric field formed between the first electrode and the second electrode comprises transverse electric fields in the left-right direction and the up-down direction, the free ions in each area can be adsorbed, the free ions in the display area are reduced, and the problem of display afterimage of the liquid crystal display panel is improved.
Specifically, the above embodiments have been described in detail by taking an example that the first electrode is disposed in the first non-display area and the fourth non-display area, and the second electrode is disposed in the second non-display area and the fourth non-display area, but the embodiments of the present application are not limited thereto, for example, the first electrode and the second electrode may be exchanged with each other, the first electrode may also be disposed in the first non-display area and the second non-display area, and the corresponding second electrode is disposed in the third non-display area and the fourth non-display area.
In one embodiment, as shown in fig. 3, the third non-display region 162c includes a binding region provided with a binding terminal 17, the binding terminal 17 includes a first binding terminal 171 and a second binding terminal 172, the first electrode 15 extends from the fourth non-display region 162d to the third non-display region 162c and is connected to the first binding terminal 171, and the second electrode 16 is connected to the second binding terminal 172. When the first electrode and the second electrode are arranged, the first electrode and the second electrode can be respectively connected to the first binding terminal and the second binding terminal of the binding region, different voltages are input through the first binding terminal and the second binding terminal, so that a voltage difference exists between the first electrode and the second electrode, the first electrode and the second electrode generate an electric field in the horizontal direction, free ions are driven, the number of the free ions in the display region is reduced, and the problem of display image retention of the liquid crystal display panel is solved.
Specifically, fig. 3 shows a first binding terminal and a second binding terminal, but the application does not limit that the driver chips connected to the first binding terminal and the second binding terminal are different, that is, the first binding terminal and the second binding terminal may be different terminals connected to the same driver chip, and the voltages output by the two binding terminals may be different.
Specifically, when signals of the first electrode and the second electrode are input and output, the metal wires of the same film layer as the gate and the source and drain may be used to transmit the signals, and the binding terminal is connected to the first electrode and the second electrode to input and output the signals.
Specifically, in order to facilitate viewing the setting position of each non-display area, specific areas and traces in each non-display area are not shown in fig. 3, and the setting of each non-display area is specifically described as follows.
Specifically, the first non-display area comprises an electrostatic protection circuit, the second non-display area comprises a gate drive circuit and an electrostatic protection circuit, the third non-display area comprises a binding area, a fan-out area and an electrostatic protection circuit, and the fourth non-display area comprises a gate drive circuit and an electrostatic protection circuit.
Specifically, for the arrangement mode of the first electrode and the second electrode, when the first electrode and/or the second electrode are located in the first non-display area, the second non-display area and the fourth non-display area, the first electrode and/or the second electrode may be arranged outside the electrostatic protection circuit and the gate driving circuit, and when the first electrode and/or the second electrode is arranged in the third non-display area, the first electrode and/or the second electrode may be arranged in the fan-out area, thereby avoiding affecting other routing of the liquid crystal display panel.
In one embodiment, as shown in fig. 1, the first electrode 15 is disposed on the first substrate 11, and the second electrode 16 is disposed on the first substrate 11. The first electrode and the second electrode are arranged on the first substrate, so that a curved electric field from the first electrode to the second electrode can be formed by the first electrode and the second electrode, and free ions move to two sides and downwards onto the first electrode and the second electrode under the action of the electric field, so that the free ions in a display area are reduced, and the problem of display residual image of the liquid crystal display panel is solved.
In one embodiment, the first substrate further includes a conductive layer and a pixel electrode layer, the conductive layer is disposed on a side of the pixel electrode layer close to the liquid crystal layer, and the conductive layer includes a first electrode and a second electrode. First electrode and second electrode are formed through setting up the conducting layer, avoid first electrode and second electrode to influence the setting of other retes.
The problem that the thickness of a liquid crystal display panel is increased due to the fact that the film layers where the first electrode and the second electrode are additionally arranged on the first substrate is solved. In one embodiment, the first substrate includes a pixel electrode layer including a pixel electrode and a second electrode disposed to be insulated from the pixel electrode. The second electrode is arranged on the pixel electrode layer, a film layer does not need to be added to form the second electrode, and the thickness of the liquid crystal display panel is reduced.
In one embodiment, the pixel electrode layer further includes a first electrode, and the first electrode is insulated from the pixel electrode; or the pixel electrode includes a first electrode.
Specifically, when the first electrode is arranged, the first electrode can be arranged on the pixel electrode layer, the thickness of the liquid crystal display panel is reduced, different electric signals are respectively input to the first electrode and the second electrode, so that the first electrode and the second electrode generate electric fields in the horizontal direction, free ions in the display area move to the non-display area, the number of the free ions in the display area is reduced, and the problem of display image retention of the liquid crystal display panel is improved.
Specifically, when the first electrode is arranged, the pixel electrode can be multiplexed into the first electrode, the pixel electrode generally outputs an electrical signal higher than that of the common electrode, and the electrical signal of the pixel electrode adopted by the first electrode can form a potential difference with the second electrode, so that the first electrode and the second electrode form an electric field to adsorb free ions, and the first electrode and the second electrode cannot work during display, so that the time-sharing multiplexing of the first electrode and the pixel electrode cannot influence the normal display of the display panel, and the arrangement mode can reduce the thickness of the liquid crystal display panel and reduce the preparation process of the liquid crystal display panel.
The problem that the thickness of a liquid crystal display panel is increased due to the fact that a film layer where a first electrode and a second electrode are additionally arranged on a first substrate is solved. In one embodiment, the first substrate includes a common electrode layer including a common electrode, a first electrode and a second electrode, the first electrode being disposed in insulation with the common electrode, and the second electrode being disposed in insulation with the common electrode. When the first electrode and the second electrode are arranged, the first electrode and the second electrode can be arranged on the common electrode layer, and the thickness of the liquid crystal display panel is reduced.
Specifically, since the common electrode is arranged in a whole layer, in order to enable the electric field formed by the first electrode and the second electrode to cover each area of the display area, the first electrode and the second electrode are arranged in an insulated way from the common electrode, and the free ions are driven to move to the first electrode and the second electrode by the electric field formed by the first electrode and the second electrode, so that the free ions in the display area are reduced, and the problem of display image retention of the liquid crystal display panel is solved.
Specifically, since the first electrode and the second electrode are disposed in the non-display region, even if the first electrode and the second electrode are formed separately in the non-display region, the common electrode does not have an excessive influence on a signal of the common electrode located in the display region, and thus, a display signal during display can be transmitted normally, and a display screen can be displayed normally.
In one embodiment, the first electrode is disposed on the first substrate, and the second electrode is disposed on the second substrate. When the first electrode and the second electrode are arranged, the first electrode and the second electrode can be arranged on two sides of the liquid crystal layer, so that the first electrode and the second electrode form an oblique electric field, free ions in the display area can be driven, the free ions in the display area can move to the non-display area, the free ions in the display area are reduced, and the problem of display residual image of the liquid crystal display panel is solved.
It should be noted that, in the present application, the working time of the first electrode and the second electrode is different from the display time before shipment and before power on/off, so that even if the first electrode and the second electrode are disposed on the same layer as the film layer in the liquid crystal display panel or the multiplexing electrode, the working time is different, and the signal in the normal display will not be affected.
