In the case where the embodiment of the present application range, the first viewing area can also be referred to as the second viewing area, similarly, the second viewing area
The first viewing area can also be referred to as.
In order to clearly illustrate liquid crystal display panel provided by the embodiment of the present application, below to liquid crystal display panel
Structure be illustrated.
In liquid crystal display panel include viewing area and non-display area, non-display area be arranged functional module group, viewing area into
Row image is shown.
Sub-pixel SP, each sub-pixel SP including array arrangement are correspondingly arranged on thin film transistor (TFT) in the display area,
In, array can be divided into line direction and column direction.In order to which the sub-pixel SP of drive array arrangement shows picture, also set in viewing area
It is equipped with data signal line and scan signal line, scan signal line and data signal line are prolonged along the both direction of array respectively
It stretches.
Scan signal line is exemplified below and data signal line is the sub-pixel SP display figure for how controlling array arrangement
As.
It is provided with M row, the sub-pixel SP of N column in viewing area, and is correspondingly arranged on M row, the thin film transistor (TFT) of N column, by M
Rower is denoted as { X1, X2 ... ..., XM }, and N column are labeled as { Y1, Y2 ... ..., YN }, then line a, the sub-pixel SP of B column, just
It can be indicated with (XA, XB), above-mentioned M, N, A, B are positive integers, and 1≤A≤M, 1≤B≤N.
Scan signal line extends along line direction, and the grid of thin film transistor (TFT) corresponding with each sub-pixel SP is electrically connected respectively
It connects, data signal line extends along column direction, respectively the source electrode electrical connection of thin film transistor (TFT) corresponding with each sub-pixel SP.
Thin film transistor (TFT) has ON state and OFF state, and the state of thin film transistor (TFT) is controlled by grid.It is brilliant that grid is similar to film
The switch of body pipe, when high voltage is transmitted to grid by scan signal line, grid is in ON state, produces between source electrode and drain electrode
Raw operating current, the data signal transmission for allowing data signal line to transmit to sub-pixel.When scan signal line stops mentioning to grid
When for high voltage, grid is in OFF state, and the operating current between source electrode and drain electrode disappears, the data of data signal line transmission
Signal can not be transmitted to sub-pixel.
When sub-pixel SP shows image, scan signal line transmits scanning signal, and scanning signal can successively control every a line
The grid of thin film transistor (TFT) become ON state, and only have the thin film transistor (TFT) of a line to be in ON state, such as in synchronization
When the grid of XA row is all ON state, the grid of { X1 ... ..., XA-1, XA+1 ... ..., XM } row is all OFF state.When XA is from X1 mono-
When directly becoming XM, that is, complete the single pass to entire array.
Corresponding with the scanning process of scan signal line, data signal line transmits data-signal, and driving grid is in ON state
Thin film transistor (TFT) work, data-signal is transmitted to corresponding sub-pixel SP by the thin film transistor (TFT) that grid is in ON state,
So that corresponding sub-pixel SP shines.For the thin film transistor (TFT) that do not go together, the data-signal that data signal line issues mutually is strained
Change, so that the sub-pixel SP not gone together issues different light.When scanning signal completes the single pass to entire array,
Different data-signal correspondences has also been transferred to each of entire array thin film transistor (TFT) by data signal line.
Since the vision of human eye is detained, i.e., image seen by person can stop about 1/24s in brain, when scanning signal is corresponding
Scan period be less than 1/24s when, human eye can see the image that the sub-pixel SP in entire array is shown jointly.
It should be noted that backlight module is provided with away from the side of light emission side in liquid crystal display panel, on backlight module
Light source issue same intensity white light, pass through liquid crystal display panel, liquid crystal display panel is shone.
Thin film transistor (TFT) control sub-pixel SP shows that the principle of image is that sub-pixel SP sending is controlled by electric field change
Different light.Specifically, thin film transistor (TFT) includes pixel electrode and public electrode, and electricity is formed between pixel electrode and public electrode
, so that the liquid crystal molecule in the liquid crystal layer of liquid crystal display panel rotates.It is appreciated that different subpixel SP is corresponding thin
The electric field that film transistor is formed is different, therefore the white light of the same intensity of backlight module sending, and it is corresponding to pass through different subpixel SP
Liquid crystal molecule after, the intensity of the corresponding white light of different subpixel SP is different.Further, different subpixel SP corresponds to difference
The colored light-filtering units of color become intensity after the white light after liquid crystal molecule passes through the colored light-filtering units of different colours
Light different, color is different.
Adjacent multiple sub-pixel SP form multiple sub-pixel SP that pixel a PX, each pixel PX include and issue difference
The light of intensity, different colours forms monochromatic light after light mixing, so that entire pixel PX issues the monochromatic light.
For traditional liquid crystal display panel, thin film transistor (TFT) is corresponding with the sub-pixel SP of array distribution, and every a line is thin
The quantity of film transistor is identical.That is, the quantity of the thin film transistor (TFT) of each scan signal line electrical connection is identical, scanning
When the thin film transistor (TFT) that signal driving is not gone together becomes ON state, the quantity for the thin film transistor (TFT) for needing to drive is identical, therefore each
The load of scan signal line is also identical.
When functional module group is arranged in viewing area, need that hollow out function is arranged in the viewing area of liquid crystal display panel
Area, for functional module group to be arranged, partial region around hollow out functional areas and hollow out functional areas does not have sub-pixel SP, does not have yet
There is control sub-pixel SP to show the thin film transistor (TFT) of image.
It is appreciated that by the scan signal line of hollow out functional areas, due to the presence of hollow out functional areas, the film of electrical connection
The load of the negligible amounts of transistor, this partial scan signal line is also smaller.
During scanning entire display panel, since liquid crystal display panel is swept to what each line scan signals line provided
The total voltage for retouching signal is identical, and the thin film transistor (TFT) with negligible amounts is electrically connected, so that the lesser scanning letter of load
For number line, the scanning voltage shared on each thin film transistor (TFT) is larger, so that the work between source electrode and drain electrode
Electric current is larger, and the intensity for the data-signal that sub-pixel SP is received is larger.
For entire liquid crystal display panel, the operating current for the corresponding thin film transistor (TFT) of sub-pixel SP that do not go together is not
Together, lead to the brightness irregularities of sub-pixel SP that do not go together, so that display is uneven.
To solve the above-mentioned problems, the embodiment of the present application proposes a kind of liquid crystal display panel.Fig. 1 is the embodiment of the present application
The structural schematic diagram of provided liquid crystal display panel.Fig. 2 is a kind of enlarged diagram in the region R1 in Fig. 1.Fig. 3 is in Fig. 2
Along a kind of schematic cross-section of dotted line A-A ', it should be noted that illustrate only two datas letter for ease of description, in Fig. 3
Number line and two scan signal lines, data signal line not as the liquid crystal display panel proposed to the embodiment of the present application and sweep

As shown in Figure 1-3, liquid crystal display panel includes viewing area 11 and hollow out functional areas 12, hollow out functional areas 12 are for holding
Receive functional module group, viewing area 11 is arranged around hollow out functional areas 12.
Liquid crystal display panel includes data signal line 131 and scan signal line 132, in viewing area 11, data signal line 131
Setting is extended in a first direction, scan signal line 132 is extended in a second direction.Wherein, first direction and second direction phase
It hands over.Optionally, first direction and second direction are the column direction and line direction in aforementioned array arrangement respectively.
Between hollow out functional areas 12 and viewing area 11, it is provided with First Transition area 13, First Transition area 13 surrounds hollow out
Functional areas 12.In First Transition area 13, data signal line 131 and scan signal line 132 are arranged around hollow out functional areas 12.?
One transition region 13, data signal line 131 the first plane upright projection, with scan signal line 132 in the vertical of the first plane
Projection overlaps on multiple coincidence points.Wherein, the first plane is the plane where liquid crystal display panel light emission side surface.
It should be noted that since data signal line 131 and scan signal line 132 are the signal wires with one fixed width,
Corresponding upright projection is also to have one fixed width.Therefore, the overlapping coincidence point of upright projection is not have in mathematical meaning
There is a point of size, but overlapping region.
As shown in Fig. 2, multiple upright projection coincidence points of data signal line 131 and scan signal line 132 are located at void in figure
In wire frame 133, therefore, in dotted line frame 133, therefore liquid crystal display panel provided by the embodiment of the present application is in dotted line frame 133
Interior setting metal auxiliary electrode 134.
It should be noted that data signal line 131 and scan signal line 132 pass through transmission electricity in liquid crystal display panel
It presses signal to drive thin film transistor (TFT), therefore will form at the projection coincidence point of data signal line 131 and scan signal line 132
Coupled capacitor, it is each since multiple upright projection coincidence points of data signal line 131 and scan signal line 132 are independent a little
Coupled capacitor can be all generated at a coincidence point.
Therefore, in order to increase the coupled capacitor between data signal line 131 and scan signal line 132, at least one coincidence
Point needs to be located at metal auxiliary electrode 134 inside the upright projection of the first plane.
Liquid crystal display panel provided by the embodiment of the present application, including viewing area 11, hollow out functional areas 12 and First Transition
Area 13.The sub-pixel SP of array arrangement is provided in viewing area 11, and by extending respectively along first direction and second direction

Pipe, to drive sub-pixel SP to issue the light of different colours, varying strength.
Hollow out functional areas 12 are not provided with sub-pixel SP, also without corresponding film crystal for accommodating functional module group 410
Pipe, therefore data signal line 131 and scan signal line 132 be in the First Transition area 13 around hollow out functional areas 12, around engraving
Empty functional areas 12 are arranged.
In hollow out functional areas 12 and First Transition area 13, it is not provided with sub-pixel SP, is not also correspondingly arranged the sub- picture of driving
Plain SP luminous thin film transistor (TFT), so that by the scan signal line 132 in First Transition area 13, compared to without First Transition
The scan signal line 132 in area 13 loads the sub- picture positioned at viewing area 11 that is smaller, and then influencing the scan signal line 132 driving
The display effect of plain SP.
In First Transition area 13, data signal line 131 and scan signal line 132 are due to cabling intersection, in crossover location
It will form coupled capacitor, and the generation of coupled capacitor can increase the load of scan signal line 132.In order to increase by First Transition
The load of the scan signal line 132 in area 13 is correspondingly arranged metal auxiliary electrode 13, Lai Zeng great data-signal in First Transition area 13
Coupled capacitor between line 131 and scan signal line 132, to increase the scan signal line 132 by First Transition area 13
Load.So that the load of the scan signal line 132 by First Transition area 13, with the scanning signal without First Transition area 13
The load of line 132 is approximately equal or even equal, to be located at display by what the scan signal line 132 in First Transition area 13 drove
The scanning voltage that thin film transistor (TFT) corresponding to the sub-pixel SP in area 11 is shared, with the scan line without First Transition area 13
The scanning voltage size that thin film transistor (TFT) corresponding to the sub-pixel SP of 132 drivings is shared is approximately equal or even equal, thus
So that the display of sub-pixel SP is uniform, display effect is promoted.
Optionally, the multiple coincidence point is entirely located in the metal auxiliary electrode in the upright projection of first plane
Within.It, can be to each when multiple coincidence points are entirely located in metal auxiliary electrode 134 within the upright projection of the first plane
Coupled capacitor at a coincidence point is all increased, so that the load for being located at the scan signal line 132 in First Transition area is further
Increase.
As shown in figure 3, liquid crystal display panel further includes the first metal layer M1, second metal layer M2 and third metal layer M3,
The first metal layer M1 patterns to form data signal line 131, and second metal layer M2 patterns to form scan signal line 132, third
Metal layer M3 patterns to form metal auxiliary electrode 134.Wherein, second metal layer M2 is located at the first metal layer M1 and third metal
Between layer M3.
The explanation of image displaying principle based on foregoing liquid crystal display panel, it is recognised that array in liquid crystal display panel
The thin film transistor (TFT) of arrangement works, so that corresponding sub-pixel SP shines, thin film transistor (TFT) includes source electrode and drain electrode 111
(the same technique of same material is made, and is all labeled herein with 111), grid 112, semiconductor portion 114.Wherein, source electricity
Pole and drain electrode 111 and data signal line 131 can be patterned by metal layer M1 to be formed, and grid 112 and scan signal line 132 can
