Detailed Description
In order to make those skilled in the art better understand the technical solution of the present invention, the technical solution of the present invention is further described in detail below with reference to the accompanying drawings and the detailed description.
Referring to fig. 1, the lcd panel 100 is divided into a peripheral area 100a and an operable area 100b, wherein a GOA circuit (not shown) is disposed in the peripheral area 100 a. The operable area 100b, i.e., the AA area, is within the understanding of those skilled in the art and will not be described herein.
In order to explain a light shielding scheme of the GOA circuit disposed in the peripheral region 100a, the internal structure of the liquid crystal display panel 100 will be explained below.
Referring to fig. 2, wherein fig. 2 is a partial cross-sectional view of the liquid crystal display panel in fig. 1, that is, a cross-sectional view of the surrounding area 100a, in an embodiment of the liquid crystal display panel of the present invention, the liquid crystal display panel 100 includes a lower substrate 110 and an upper substrate 120 which are spaced apart from each other.
In this embodiment, the lower substrate 110 is an array substrate, and the upper substrate 120 is a color filter substrate. A main light shielding structure 130 is disposed on a side of the upper substrate 120 adjacent to the lower substrate 110, and the main light shielding structure 130 is a layered structure made of black light spacer material (i.e., BPS material), that is, the main light shielding structure 130 is a light shielding layer. As can be seen from the above description, when the main light shielding structure 130 shields light to the driving circuit (such as the gate driving circuit of the array substrate, i.e., the GOA circuit) disposed in the peripheral region 100a, there is a problem of light leakage, and therefore, the auxiliary light shielding structure 140 is disposed around the lower substrate 110 for auxiliary light shielding to the driving circuit (not shown) disposed around the lower substrate 110.
The auxiliary light shielding structure 140 includes a first light shielding structure 141 and a second light shielding structure 142, the first light shielding structure 141 is a plurality of metal blocks 1411 disposed at intervals and used for a gate of a thin film transistor, and the second light shielding structure 142 is disposed on a side of the lower substrate 110 close to the upper substrate 120, in this embodiment, the second light shielding structure 142 is disposed corresponding to a gap between the plurality of metal blocks 1411.
Through the implementation of the above embodiment, the auxiliary light shielding structure 140 cooperates with the main light shielding structure 130 to shield light to the driving circuit disposed in the peripheral area 100a, so as to effectively solve the problem of light leakage, and the second light shielding structure 140 corresponds to the gap between the plurality of metal blocks 141, so that the free space between the lower substrate and the upper substrate is increased, and the problem that the sealant is pierced due to the small free space can be avoided.
Specifically, referring to fig. 2, the plurality of metal blocks 1411 arranged at intervals includes a plurality of first metal blocks 1411a arranged at intervals and a plurality of second metal blocks 1411b arranged at intervals, in this embodiment, the length of the first metal block 1411a is greater than or equal to a preset length, and the length of the second metal block 1411b is less than the preset length. The length of the first metal block 1411a is greater than or equal to a predetermined length because the first metal block 1411a is used for gates of a plurality of series-connected thin film transistors, and further, in order to satisfy that the length of the first metal block 1411a is greater than or equal to the predetermined length, the first metal block 1411a is used for gates of at least three series-connected thin film transistors, and in order to satisfy that the length of the second metal block 1411b is less than the predetermined length, the second metal block 1411b is used for gates of a single thin film transistor or two thin film transistors.
Further, since the length of the first metal block 1411a is greater than or equal to the predetermined length, the first metal block 1411a itself has a certain light shielding effect, and the second light shielding structure 142 corresponds to the gap between the plurality of first metal blocks 1411a, so as to effectively increase the free space between the lower substrate 110 and the upper substrate 120. When the plurality of spaced metal blocks 1411 includes a plurality of spaced first metal blocks 1411a, the second light shielding structure 142 is disposed corresponding to a gap between the plurality of first metal blocks 1411a, that is, the second light shielding structure 142 corresponds to only a gap between the first metal blocks 1411 a.
Since the length of the second metal blocks 1411b is less than the predetermined length, the gap between the second metal blocks 1411b may be similar to or the same as the length of the second metal blocks 1411b, and at this time, if the second light shielding structure 142 is disposed corresponding to the gap between the second metal blocks 1411b, the processing difficulty is large, and the increased empty space is small, so that when the plurality of second metal blocks 1411b are continuously spaced, to reduce the processing difficulty, the second light shielding structure 142 is disposed corresponding to the plurality of second metal blocks 1411b that are spaced, that is, the second light shielding structure 142 corresponds to the gap between the second metal blocks 1411b and the second metal blocks 1411 b.
Further, in the present embodiment, the second light shielding structure 142 includes a plurality of first color blocking blocks 1421 respectively disposed above the gaps between the plurality of first metal blocks 1411a and at least one first color blocking block 1421 continuously disposed above the plurality of second metal blocks 1411b disposed at intervals, and a second color blocking block 1422 correspondingly disposed on the first color blocking block 1421. When the plurality of second metal blocks 1411b are continuously spaced, in order to reduce the difficulty in processing and manufacturing, the first color blocking blocks 1421 corresponding to the gaps between the second metal blocks 1411b are continuously disposed, that is, one second color blocking block 1421 corresponds to the plurality of first metal blocks disposed at intervals and the gaps therebetween, and accordingly, the lengths of the plurality of first color blocking blocks 1421 are different from each other. It can be seen that the second light shielding structure 142 includes a plurality of first metal blocks 1411a and corresponding second metal blocks 1411b, a plurality of first color blocking blocks 1421 are in one-to-one correspondence with gaps between the plurality of first metal blocks 1411a and the plurality of second metal blocks 1411b arranged at intervals, and meanwhile, a plurality of second color blocking blocks 1422 are in one-to-one correspondence with the plurality of first color blocking blocks 1421. The second color block 1422 is disposed on the first color block 1421, that is, the second light shielding structure 142 adopts a color-resistor stacking manner, and the size, such as the length, of the first color block 1421 and the second color block 1422 is determined by the gap between the first metal blocks 1411a and the second metal blocks 1411b disposed at intervals.
