Between pixel openings area 212；
It is located between two sub-pixels open region 21 adjacent on line direction X through area 11.
In the present embodiment, a kind of the first sub-pixel open region 211 of each pixel unit 2 is provided, the second sub-pixel is opened
Mouth region 212, third sub-pixel open region 213 are the arrangement mode how to arrange on odd column and even column respectively, and
It illustrates, through the position that area 11 is arranged, to make the position through area for such pixel arrangement, a pixel unit 2 can be made
Interior includes that at least one penetrates area 11, and this can be made to be reflected into fingerprint identification unit through the more raising of the setting energy in area 11
The transit dose of light on 02, to reinforce the accuracy of identification of fingerprint identification unit 02.
In some optional embodiments, with continued reference to FIG. 3, in the present embodiment, it is located at through area 11 adjacent on line direction X
Two the first sub-pixel open regions 211 between, through being not provided with walking line portion 011 in area 11, adjacent two on line direction X
Two walking line portions 011 are equipped between second sub-pixel open region 212, the upper two adjacent third sub-pixels of line direction X are open
A walking line portion 011 is equipped between area 213；
Or referring to FIG. 4, Fig. 4 is the third structural representation of the display panel 00 of the embodiment of the present invention, through area 11
Or it is located on line direction X between adjacent two the first sub-pixel open regions 211, through being not provided with walking line portion in area 11
Two walking line portions 011, phase on line direction X are equipped on 011, line direction X between two adjacent third sub-pixel open regions 213
A walking line portion 011 is equipped between two adjacent the second sub-pixel open regions 212.
It should be noted that in the present embodiment, for above-mentioned each pixel unit 2 the first sub-pixel open region 211,
Two sub-pixel open regions 212, third sub-pixel open region 213 arrangement mode on odd column and even column respectively, through area
The setting of 11 positions can there are three types of modes, as long as being located at two sub-pixels open region adjacent on line direction X through area 11
Between 21, for example penetrates area 11 and be located between two the first sub-pixel open regions 211 adjacent on line direction X, or penetrate area
11 are located between two the second sub-pixel open regions 212 adjacent on line direction X, or are located at phase on line direction X through area 11
Between two adjacent third sub-pixel open regions 213.The present embodiment selection is located at adjacent two on line direction X through area 11
Between a first sub-pixel open region 211, because being equipped between two third sub-pixel open regions 213 adjacent on line direction X
Two walking line portions 011 are equipped with a walking line portion on line direction X between two adjacent the second sub-pixel open regions 212
011, then corresponding, on line direction X adjacent two between two adjacent third sub-pixel open regions 213, on line direction X
It can be provided with PS column between a second sub-pixel open region 212, therefore in order to avoid the arrangement of PS column, make through the saturating of area 11
Cross that rate is bigger, will transmit through area 11 to be arranged between two the first sub-pixel open regions 211 adjacent on line direction X is preferably to implement
Example.
If the first sub-pixel open region 211 in the present embodiment is defined as glowing, the definition of the second sub-pixel open region 212
For green light, third sub-pixel open region 213 is defined as blue light-emitting, due to for identical light signal strength, feux rouges it
Between, compare between green light, between blue light, fingerprint identification unit 02 receives the optical signal amount between feux rouges between green light most
Greatly, so as to so that the identification of fingerprint identification unit 02 is more sensitive；Therefore there are two types of preferably square through the setting of the position in area 11
Formula, one is transmission areas 11 to be set between two the first sub-pixel open regions 211 adjacent on line direction X between i.e. feux rouges,
Another kind is set between two the second sub-pixel open regions 212 adjacent on line direction X between i.e. green light through area 11, this
What embodiment was chosen is to be located between two the first sub-pixel open regions 211 adjacent on line direction X to carry out example through area 11
Explanation.It should be further noted that since fingerprint identification unit 02 receives the optical signal amount intensity between blue light compared to red
Between light between green light for it is weaker, therefore to avoid being set to two thirds adjacent on line direction X as far as possible through area 11
Between sub-pixel open region 213, therefore the present embodiment is not considered this setting.
And it is located at the setting side between two the first sub-pixel open regions 211 adjacent on line direction X for through area 11
Formula does not change the averag density of touch control electrode 01 in order to not influence the touch-control sensitivity of touch control electrode 01, can be in a picture
To the setting in the walking line portion 011 of metal grill in plain unit 2, there are Fig. 3 and two ways shown in Fig. 4.
It should be noted that the present embodiment has been merely illustrative of the arrangement side of figure 3 above and two kinds of metal grills of Fig. 4
Formula is to illustrate the present embodiment is how can be not provided with metal grill through area 11, and can not change in order to clearer
The averag density of touch control electrode 01, therefore the present embodiment is not limited to walking line portion 011 and the column cabling of such metal grill
The arrangement mode in portion 012, the metal grill arrangement mode of remaining structure, as long as through metal grill and not is not provided in area 11
Change 01 averag density of touch control electrode within the protection scope of the present embodiment.
In some optional embodiments, referring to FIG. 5, Fig. 5 is the structural representation of the display panel 00 of the embodiment of the present invention
The four of figure, in the present embodiment, the length in the walking line portion 011 on odd column is L1,011 length of walking line portion on even column
It is L2, L1 is less than L2；Through first sub-pixel open region 211 side and of the area 11 on the even column between adjacent column
Two sub-pixel open regions, 212 side.
In the present embodiment, it is open for the first sub-pixel open region 211 of above-mentioned each pixel unit 2, the second sub-pixel
Area 212, third sub-pixel open region 213 arrangement mode on odd column and even column respectively illustrate another through area
The set-up mode of 11 positions, and for such position being arranged through area 11, the knot of the touch control electrode 01 of metal mesh structure
Structure, even if the 011 length L2 of walking line portion on the length L1 and even column in the walking line portion 011 on odd column is unequal, and L1
Less than L2, to will transmit through between the two neighboring sub-pixel open region 21 that area 11 is arranged on wider even column；Simultaneously again
In order not to change the averag density of the touch control electrode 01 in each pixel unit 2 and make to include at least one in each pixel unit 2
It is a to penetrate area 11, then it can make to penetrate first sub-pixel open region 211 side of the area 11 on the even column between adjacent column
With 212 side of the second sub-pixel open region.If the first sub-pixel open region 211 in the present embodiment is defined as glowing, second
