The following describes the technical solutions of the present application and how to solve the above technical problems with specific embodiments.
First, the strength Mura failures are explained: the gravity Mura defect is a phenomenon that the color of the lower edge of the liquid crystal display panel is uneven when the liquid crystal display panel is in a working state, and is generally caused by the liquid crystal sinking under the action of gravity and high temperature when the liquid crystal amount is too much.
Referring to fig. 1 to 3, an embodiment of the present application provides a liquid crystal display panel, including: the liquid crystal display panel comprises an array substrate 100 and a color film substrate 200 which are arranged in an opposite box mode, and a liquid crystal layer 300 is arranged between the array substrate 100 and the color film substrate 200.
The liquid crystal layer 300 is disposed with a liquid crystal 310 and a plurality of main spacers 320, and two ends of the main spacers 320 are respectively connected to the array substrate 100 and the color film substrate 200. The liquid crystal layer 300 is divided into a first liquid crystal region 340 and a second liquid crystal region 350; in the operating state of the liquid crystal display panel, the first liquid crystal region 340 is located above the second liquid crystal region 350.
For convenience of description, the main spacers located in the first liquid crystal region 340 are named first main spacers 320, and the main spacers located in the second liquid crystal region 350 are named second main spacers 321.
In any plane of the liquid crystal layer 300 parallel to the array substrate 100, the cross-sectional dimensions of the first main spacers 320 in the first liquid crystal region 340 are all larger than the cross-sectional dimensions of the first main spacers 320 in the second liquid crystal region 350.
In the liquid crystal display panel provided by this embodiment, the cross-sectional dimension of the first main spacer 320 in the first liquid crystal region 340 is designed to be larger than the cross-sectional dimension of the second main spacer 321 in the second liquid crystal region 350, so that the compression amount of the first main spacer 320 in the first liquid crystal region 340 is smaller than the compression amount of the second main spacer 321 in the second liquid crystal region 350, thereby effectively preventing the liquid crystal 310 in the first liquid crystal region 340 from flowing down to the second liquid crystal region 350, and further improving the gravity Mura defect. In this embodiment, the array substrate 100 and the color filter substrate 200 are arranged in a pair to form a liquid crystal cell structure. A liquid crystal layer 300 is disposed between the liquid array substrate 100 and the color film substrate 200, and liquid crystal in the liquid crystal layer 300 is sealed by the sealant 400 to prevent leakage. The liquid crystal layer 300 is further provided with a plurality of first main spacers 320, the liquid crystal layer 300 and the first main spacers 320 jointly support to form a space between the color film substrate 200 and the array substrate 100, and the periphery of the space is sealed by the frame sealing glue 400.
For convenience of description, the liquid crystal layer 300 is divided into a first liquid crystal region 340 and a second liquid crystal region 350. Specifically, in the working state of the liquid crystal display panel, the first liquid crystal region 340 is located above the second liquid crystal region 350, the upper side includes a right upper side and an oblique upper side in the embodiment, and the liquid crystal in the upper first liquid crystal region 340 will flow to the second liquid crystal region 350 under the action of gravity. It should be noted that the operating state of the liquid crystal display panel includes a product test state and an end use state. Taking the lcd television as an example, the lcd television is hung on a wall or supported by a bracket when in use, and the operating state of the lcd television is considered as the present state.
In this embodiment, one end of the first main spacer 320 is connected to the color film layer 210 of the color film substrate 200, and the other end is connected to the tft device 110 of the array substrate 100. The first main spacer 320 is in a columnar structure, and the cross-sectional dimension of the first main spacer 320 decreases gradually from the color film substrate 200 to the array substrate 100. Based on this, in the present embodiment, in the plane where any one (any one) of the liquid crystal layers 300 is parallel to the array substrate 100, the cross-sectional size of the first main spacers 320 in the first liquid crystal region 340 is set to be larger than the cross-sectional size of the first main spacers 320 in the second liquid crystal region 350, so that the size of the first main spacers 320 in the first liquid crystal region 340 is larger than the size of the second main spacers 321 in the second liquid crystal region 350 as a whole, thereby reducing the compression amount of the first main spacers 320 in the first liquid crystal region 340.
In some embodiments, with reference to fig. 2, the liquid crystal layer 300 is parallel to the vertical direction in the working state of the liquid crystal display panel, i.e. the liquid crystal display panel is arranged in the vertical direction in the working state, which is convenient for the user to use and watch.
In some embodiments, on the basis that the size of the plurality of first main spacers 320 in the first liquid crystal region 340 is larger than the size of the plurality of first main spacers 320 in the second liquid crystal region 350, in order to facilitate the fabrication of the first main spacers 320, the size of the plurality of first main spacers 320 in the first liquid crystal region 340 may be designed to be the same, as shown in fig. 3, that is, the cross-sectional size of the plurality of first main spacers 320 in the first liquid crystal region 340 is the same in any plane of the liquid crystal layer 300 parallel to the array substrate 100.
In addition, with reference to fig. 3, only the first main spacers 320 in the second liquid crystal region 350 may be designed to have the same size, that is, the cross-sectional sizes of the first main spacers 320 in the second liquid crystal region 350 are the same in any plane of the liquid crystal layer 300 parallel to the array substrate 100.
In some embodiments, with continued reference to fig. 3, the first main spacers 320 in the first liquid crystal region 340 may be uniformly sized, and the first main spacers 320 in the second liquid crystal region 350 may be uniformly sized, that is, the cross-sectional sizes of the first main spacers 320 in the first liquid crystal region 340 are the same, and the cross-sectional sizes of the first main spacers 320 in the second liquid crystal region 350 are the same, in any plane of the liquid crystal layer 300 parallel to the array substrate 100.
In the liquid crystal display panel provided by this embodiment, the sizes of the first main spacers 320 in at least a partial region of the liquid crystal layer 300 may be set to be the same, which is beneficial to manufacturing the first main spacers 320, thereby improving the manufacturing efficiency of the liquid crystal display panel.
In some embodiments, in order to better suppress the flow of the liquid crystal, as shown in fig. 4 and 5, the cross-sectional size of the first main spacers 320 in the liquid crystal layer 300 gradually increases along the second liquid crystal region 350 toward the first liquid crystal region 340 in a plane parallel to the array substrate 100 in any one of the liquid crystal layers 300. For example: based on the cross-sectional dimension of the first main spacers 320 at the lower edge (which may be one or several rows) of the liquid crystal display panel, the cross-sectional dimension of the first main spacers 320 in each row or several rows gradually increases according to a certain proportionality coefficient along the direction from the second liquid crystal region 350 to the first liquid crystal region 340, and the specific proportionality coefficient may depend on the resolution of the liquid crystal display panel.
On the basis of the above embodiments, with continued reference to fig. 4 and 5, the number of the first main spacers 320 located in the first liquid crystal region 340 is greater than the number of the second main spacers 321 located in the second liquid crystal region 350.
In this embodiment, the number of the first main spacers 320 in the first liquid crystal region 340 is set to be greater than the number of the second main spacers 321 in the second liquid crystal region 350, that is, the density of the first main spacers 320 in the first liquid crystal region 340 is generally greater than the density of the second main spacers 321 in the second liquid crystal region 350, so that the compression amount of the first main spacers 320 in the first liquid crystal region 340 is smaller than the compression amount of the second main spacers 321 in the second liquid crystal region 350, thereby further inhibiting the liquid crystal 310 in the first liquid crystal region 340 from flowing down to the second liquid crystal region 350, and further improving the gravity Mura defect.
In some embodiments, with continued reference to fig. 4 and 5, in order to improve the supporting effect between the array substrate 100 and the color filter substrate 200, a plurality of first main spacers 320 located in the first liquid crystal region 340 may be uniformly distributed in the first liquid crystal region 340.
In some embodiments, the plurality of first main spacers 320 located in the second liquid crystal region 350 are uniformly distributed in the second liquid crystal region 350.
In some embodiments, the plurality of first main spacers 320 located in the first liquid crystal region 340 are uniformly distributed in the first liquid crystal region 340, while the plurality of first main spacers 320 located in the second liquid crystal region 350 are uniformly distributed in the second liquid crystal region 350.
In some embodiments, in order to better suppress the liquid crystal flow, with reference to fig. 4 and 5, the arrangement density of the plurality of first main spacers 320 in the second liquid crystal display region gradually increases along the direction of the second liquid crystal region 350 toward the first liquid crystal region 340. Meanwhile, the arrangement density of the plurality of first main spacers 320 in the first liquid crystal region 340 gradually increases along the direction from the second liquid crystal region 350 to the first liquid crystal region 340. For example: based on the density (number) of the first main spacers 320 at the lower edge (which may be several lines or a preset area) of the liquid crystal display panel, the density of the first main spacers 320 in each several lines or each preset area is gradually increased according to a certain proportionality coefficient along the direction from the second liquid crystal area 350 to the first liquid crystal area 340, and the specific proportionality coefficient may be determined according to the resolution of the liquid crystal display panel.
In some embodiments, as shown in fig. 6, the liquid crystal layer 300 of the liquid crystal display panel further includes a plurality of auxiliary spacers to serve as auxiliary supports when the liquid crystal display panel is pressed. One end of the auxiliary spacer is connected to the color film substrate 200, and a buffer space is left between the other end of the auxiliary spacer and the array substrate 100, so that a step difference exists between the auxiliary spacer and the first main spacer 320.
For convenience of description, the auxiliary spacers in the first liquid crystal layer are named as first auxiliary spacers 330, and the auxiliary spacers in the second liquid crystal region are named as second auxiliary spacers 331.
One end of the first main spacer 320, which is close to the array substrate 100, is connected to the metal trace or the thin film transistor device 110 of the array substrate 100; one end of each of the first auxiliary spacers 330 located in the first liquid crystal region 340, close to the array substrate 100, is opposite to a metal trace of the array substrate 100 or a thin film transistor device 110(TFT), that is, one end of each of the first main spacers 320 and the first auxiliary spacers 330, close to the array substrate 100, faces the metal trace (e.g., a gate line) of the array substrate 100 or the thin film transistor device (TFT)110, where the TFT is located in a crossing and enclosing region of the gate line and the data line.
Specifically, only the first auxiliary spacer 330 of the first liquid crystal region 340 faces the TFT device unit or the metal trace of the array substrate 100, and the second auxiliary spacer 331 of the second liquid crystal region 350 faces the region outside the TFT device unit or the metal trace of the array substrate 100, that is, the buffer distance between the first auxiliary spacer 330 of the first liquid crystal region 340 and the array substrate 100 is smaller than the buffer distance between the second auxiliary spacer 331 of the second liquid crystal region 350 and the array substrate 100, so that the compression amount of the first main spacer 320 of the first liquid crystal region 340 is smaller than the compression amount of the second main spacer 321 of the second liquid crystal region 350, and the liquid crystal 310 in the first liquid crystal region 340 is further inhibited from flowing down to the second liquid crystal region 350, thereby improving the gravity Mura defect.
Alternatively, since the number of the first auxiliary spacers 330 is much greater than the number of the first main spacers 320, one first main spacer 320 may be disposed every certain number of the first auxiliary spacers 330, and so on.
On the basis of the foregoing embodiments, as shown in fig. 7, one ends of the first auxiliary spacers 330 located in the first liquid crystal region 340 and the second liquid crystal region 350, which are close to the array substrate 100, are both disposed opposite to the metal traces of the array substrate 100 or the thin film transistor devices 110; the length of the first auxiliary spacers 330 positioned in the first liquid crystal region 340 is greater than the length of the second auxiliary spacers 331 positioned in the second liquid crystal region 350.
In this embodiment, the second auxiliary spacers 331 of the first liquid crystal region 340 and the second liquid crystal region 350 both correspond to TFT device cells or metal traces of the array substrate 100, by adjusting the lengths of the first auxiliary spacers 330 of the different liquid crystal regions such that the length of the first auxiliary spacer 330 positioned in the first liquid crystal region 340 is greater than the length of the second auxiliary spacer 331 positioned in the second liquid crystal region 350, that is, the buffer pitch between the first auxiliary spacer 330 of the first liquid crystal region 340 and the array substrate 100 is smaller than the buffer pitch between the second auxiliary spacer 331 of the second liquid crystal region 350 and the array substrate 100, the compression amount of the first main spacer 320 in the first liquid crystal region 340 is smaller than the compression amount of the second main spacer 321 in the second liquid crystal region 350, so that the liquid crystal 310 in the first liquid crystal region 340 is further inhibited from flowing down to the second liquid crystal region 350, and the gravity Mura defect is improved.
In some embodiments, with reference to fig. 4, the projection areas of the first liquid crystal region 340 and the second liquid crystal region 350 on the array substrate 100 or the color filter substrate 200 are equal. Specifically, in order to facilitate the fabrication of spacers, the liquid crystal layer 300 may be equally divided into the first and second liquid crystal regions 340 and 350, and then the first main spacers 320 of corresponding sizes and numbers and the first auxiliary spacers 330 of corresponding sizes are arranged at positions corresponding to the first and second liquid crystal regions 340 and 350.
