As shown in fig. 2, the present invention provides a liquid crystal display panel, where the liquid crystal display panel 100 includes an array substrate 11, a liquid crystal layer 51, and a color filter substrate 21. A gate electrode layer 12 is arranged on the array substrate 11; the color film substrate 21 and the array substrate 11 are enclosed to form a liquid crystal box; the color filter substrate 21 is provided with a light-shielding layer 22 corresponding to the gate layer 12, and the length of the gate layer 12 is smaller than the length of the projection of the light-shielding layer 22 on the array substrate 11. The liquid crystal layer 51 is positioned in the liquid crystal box; the light shielding layer 22 has a normal working state and a deformation and dislocation state, and when the light shielding layer 22 is in the normal working state or the deformation and dislocation state, the projection of the light shielding layer 22 on the array substrate 11 covers the gate layer 12.
It should be noted that, in the conventional liquid crystal display panel in this embodiment, as shown in the figure, the length of the projection of the light shielding layer on the array substrate is the same as or greater than the length of the gate layer by 0-1 μm, the gate layer is wider and is easy to affect the inversion of the liquid crystal, in a dark state, the gate layer on the array substrate has a certain voltage, and the common electrode on the color film substrate has a certain voltage, so that an electric field is formed between the gate layer and the color film substrate, and part of the liquid crystal between the array substrate and the color film substrate is inverted and can pass light; when the liquid crystal display panel is pressed and the shading layer on the color film substrate is displaced by 1-4 microns, the display panel has the problem of pressing white clusters in a dark state; the invention provides a liquid crystal display panel 100, wherein the length of a grid layer 12 is smaller than that of a shading layer 22, when the shading layer 22 is displaced when a color film substrate 21 is pressed, the projection of the shading layer 22 on an array substrate 11 can also cover the grid layer 12, so that an electric field is generated between the grid layer 12 and a common electrode under the coverage of the shading layer 22, and light transmitted by reversed liquid crystal only irradiates on the shading layer 22 and cannot penetrate through the color film substrate 21 to irradiate out, thereby preventing the occurrence of a dark state pressing white cluster problem.
Specifically, the traditional method is used for solving the problem of pressing white clusters in a dark state by increasing the length of an original shading layer; however, increasing the length of the original light-shielding layer will decrease the aperture ratio and transmittance of the liquid crystal display panel; the invention reduces the length of the original gate layer, and the gate layer of the liquid crystal display panel 100 for transmitting voltage is mostly concentrated on the thin film transistor, so the length of the gate layer on the array substrate is reduced, and the whole liquid crystal display panel 100 is not influenced. The liquid crystal display panel 100 comprises an array substrate 11 and a color film substrate 21, the array substrate 11 and the color film substrate 21 form a liquid crystal box in a pair, and liquid crystal is arranged between the array substrate 11 and the color film substrate 21; the gate layer 12 is arranged on the array substrate 11, and the light-shielding layer 22 is arranged on the color film substrate 21 corresponding to the gate layer 12; the length of the gate layer 12 is smaller than the length of the projection of the light shielding layer 22 on the array substrate 11; that is, the length of the original gate layer on the array substrate 11 is reduced, so that the length of the light-shielding layer 22 is greater than that of the gate layer 12, and when an electric field is generated between the gate layer 12 and the common electrode on the color filter substrate 21, the inverted liquid crystal is also covered by the light-shielding layer 22 after being displaced, and light can only irradiate the light-shielding layer 22 through the inverted liquid crystal; thereby preventing the occurrence of the problem of pressing white balls in a dark state.
In an embodiment of the present application, as shown in fig. 5 and 7, a shielding layer 24 is disposed on one side or both sides of the light shielding layer 22, and when the light shielding layer 22 is in a normal operating state or a deformed and dislocated state, projections of the light shielding layer 22 and the shielding layer 24 on the array substrate 11 cover the gate layer 12.
In this embodiment, after the conventional liquid crystal display panel is mounted, the light-shielding layer of the liquid crystal display panel is arranged corresponding to the gate layer, and the gate layer and the common electrode on the color film substrate generate a voltage, so that the liquid crystal between the gate layer and the light-shielding layer is turned over; when the liquid crystal display panel is pressed by an external force, the color film substrate moves towards the lower side of the liquid crystal display panel, light can be transmitted out from the upper side of the shading layer, and the phenomenon of white cluster pressing of the liquid crystal display panel in a dark state is caused. The shading layer 22 has an up-down direction when in application, the shielding layers 24 are arranged on the upper side of the shading layer 22 or the upper side and the lower side of the shading layer 22, and the light transmitting through the inverted liquid crystal is shielded by the shielding layers 24, so that the light is prevented from transmitting out from one side of the shading layer 24 when the shading layer 22 on the color film substrate 21 is dislocated; thereby preventing the problem of pressing the white cluster in a dark state from occurring.
Specifically, a liquid crystal cell is formed by the pair of the array substrate 11 and the color film substrate 21, the gate layer 12 is arranged on the side of the array substrate 11 facing the color film substrate 21, and the light-shielding layer 22 is arranged on the side of the color film substrate 21 facing the array substrate 11; after the color film substrate 21 and the array substrate 11 are assembled, the light shielding layer 22 projects on the array substrate 11 to cover the liquid crystal between the gate layer 12 and the color film substrate 21, when the liquid crystal display panel 100 is pressed by an external force, the color film substrate 21 drives the light shielding layer 22 to move downwards, the projection of the light shielding layer 22 on the array substrate 11 is also displaced, so that the light shielding layer 22 cannot completely cover the liquid crystal between the gate layer 12 and the color film substrate 21, the shielding layer 24 is arranged on the upper side of the light shielding layer 22, when the light shielding layer 22 deviates, the light shielding layer 22 and the shielding layer 24 can cover the turned liquid crystal between the gate layer 12 and the color film substrate 21, when the liquid crystal between the gate layer 12 and the color film substrate 21 is turned, the light penetrating through the liquid crystal cannot be transmitted to the outside of the color film substrate 21, and the phenomenon of pressing white clusters in a dark state is prevented.
In an implementation manner, the shielding layers 24 are disposed on both the upper and lower sides of the light shielding layer 22, and the shielding layers 24 are disposed on both the upper and lower sides of the light shielding layer 22, so that the shielding layers 24 can block light transmitted through the liquid crystal from passing through the color filter substrate 21 no matter the color filter substrate 21 moves upward or downward, thereby preventing the white cluster from being pressed in a dark state.
In one practical form, the shielding layer 24 is provided integrally with the light shielding layer 22.
In an embodiment of the present application, when the light-shielding layer 22 is in a normal state, a length of an end portion of the shielding layer 24 far from the light-shielding layer 22 projected on the array substrate 11 to an end portion of the gate layer 12 corresponding thereto ranges from 1 to 4 micrometers.
It should be noted that, in this embodiment, a general lcd tv is vertical and has a vertical direction when in application, and when the liquid crystal glass is pressed, the color filter substrate moves downward by 0 to 4 micrometers due to the influence of gravity, so that the light shielding layer moves toward the printed circuit board, so that when the liquid crystal display panel 100 is pressed, the color filter substrate 21 drives the light shielding layer 22 to move downward, a gap occurs at an upper side of the light shielding layer 22 corresponding to an inverted liquid crystal position, and light can irradiate the outer side of the liquid crystal display panel 100 through the gap. When the light-shielding layer 22 is in a normal state, the shielding layer 24 is arranged on the light-shielding layer 22, so that the length of the projection of the end part of the shielding layer 24 far away from the light-shielding layer 22 on the array substrate 11 to the end part of the gate layer 12 corresponding to the end part is in a range of 1 to 4 micrometers; when the light shielding layer 22 is dislocated by 0-4 microns, the shielding layer 24 moves along with the light shielding layer 22, and the length distance from the end part of the shielding layer 24 far away from the light shielding layer 22 to the end part of the gate electrode layer 12 is 1-4 microns, so that the shielding layer 24 can shield the liquid crystal at the position where the liquid crystal is turned over, and light cannot penetrate out of the color film substrate 21. In the dark state, light is prevented from being transmitted out of the liquid crystal display panel 100; the occurrence of the problem of the white ball pressed in the dark state is prevented.
In an embodiment of the present application, as shown in fig. 2 and 4, a common electrode 13 is disposed on the array substrate 11 on one side of the gate layer 12, and a length of a projection of the light shielding layer 22 on the array substrate 11 and a side of the common electrode 13 close to the gate layer 12 overlap each other ranges from 1 to 4 micrometers.
It should be noted that, in this embodiment, since the common electrode 13 on the array substrate 11 and the common electrode on the color filter substrate 21 cannot generate an electric field, the liquid crystal between the array substrate 11 and the color filter substrate 21 cannot be turned over, and the liquid crystal has a certain effect of inhibiting turning over (a certain repulsive force is provided between the same electrodes), the length of the gate layer 12 at the upper side is shortened by 1 to 4 micrometers, the common electrode 13 at the corresponding upper side is increased by 1 to 4 micrometers toward the gate layer 12, and then the length of the projection of the light shielding layer 22 on the array substrate 11 and the length of the common electrode 13 coinciding with the side of the gate layer 12 are 1 to 4 micrometers; when the light shielding layer 22 is dislocated, the liquid crystal corresponding to the dislocated position of the light shielding layer 22 is ensured not to be overturned, and light is prevented from transmitting out of the color film substrate 21 from the dislocated position of the light shielding layer 22.
In an embodiment of the present application, the deformed and dislocated state is that the light shielding layer 22 moves 0 to 4 microns to one side.
In this embodiment, the light-shielding layer 22 is likely to be deformed or displaced in the vertical direction during use of the liquid crystal display panel 100.
In an embodiment of the present application, when the light-shielding layer 22 is in a normal state, a length of a projection of an end of the gate layer from a corresponding end of the light-shielding layer 22 on the array substrate 11 ranges from 1 to 4 micrometers.
In this embodiment, in order to prevent the light shielding layer 22 from being misaligned, light can be transmitted through the liquid crystal display panel 100; the lengths of the two sides of the gate layer 12 are respectively reduced by 1 to 4 micrometers, so that the range of the turned liquid crystal is reduced, and the light shielding layer 22 can still shield the turned liquid crystal when dislocation occurs; when the liquid crystal display panel 100 is in a dark state, the light-shielding layers 22 are displaced by pressing on the liquid crystal display panel 100, the projections of the displaced light-shielding layers 22 on the array substrate 11 can still cover the gate layers 12, and the inverted liquid crystal affected by the gate layers 12 is also completely covered by the displaced light-shielding layers 22, so that light transmitted through the inverted liquid crystal can only be irradiated on the displaced light-shielding layers 22 and cannot be irradiated through the color filter substrate 21. The gate layer 12 is obtained by shortening the two sides of the original gate layer by 1 to 4 micrometers, that is, the lengths of the upper end part and the lower end part from the two projected ends of the light shielding layer 22 on the array substrate 11 are any length value of 1 to 4 micrometers.
In an embodiment of the present application, the array substrate 11 is provided with the common electrodes 13 on two sides of the gate layer 12, respectively, and a length of a projection of the light shielding layer 22 on the array substrate 11 and a side of the common electrode 13 close to the gate layer 12 coincide with each other ranges from 1 to 4 micrometers.
In this embodiment, when the liquid crystal display panel 100 is stressed, the color film substrate 21 moves by an external force, which is about 0 to 4 micrometers, and the light-shielding layer 22 moves by the same distance; therefore, the invention shortens the length of the original gate layer by 1 to 4 micrometers to obtain the gate layer 12 by increasing the length of the common electrode 13, and increases the length of the original common electrode by 1 to 4 micrometers towards the gate layer 12 to obtain the common electrode 13. When the light shielding layer 22 moves in the dark state, the liquid crystal corresponding to the increased length of the common electrode 13 does not turn over, and light does not penetrate through the liquid crystal, thereby preventing the occurrence of white clusters in the dark state.
In an embodiment of the present application, as shown in fig. 2, the liquid crystal display panel 100 includes a transparent conductive film 41, and the transparent conductive film 41 is disposed on the color film substrate 21.
In this embodiment, the transparent conductive film 41 is a transparent conductive oxide, and the transparent conductive film 41 provided on the color filter substrate 21 may be used as a common electrode and is located on the side of the color filter substrate 21 facing the array substrate 11.
In an embodiment of the present application, as shown in fig. 2, a black matrix 23 is disposed on the color filter substrate 21, one end of the black matrix 23 is disposed on the light-shielding layer 22, and the other end of the black matrix is abutted to the array substrate 11.
In the present embodiment, one end of the black matrix 23 is disposed on the light-shielding layer 22, and when the color filter substrate 21 and the array substrate 11 are combined, the other end of the black matrix 23 abuts against the array substrate 11 to maintain the height of the liquid crystal cell and protect the liquid crystal from being squeezed. The black matrix 23 is columnar, and the bottom (the side with the larger bottom surface) of the black matrix 23 is provided on the light-shielding layer 22; the top of the black matrix 23 abuts on the array substrate 11; the liquid crystal is disposed in the space between the color filter substrate 21 and the array substrate 11 supported by the black matrix 23.
The invention also provides a liquid crystal display, which comprises a shell and a liquid crystal display panel 100, wherein the liquid crystal display panel 100 is arranged in the shell.
In this embodiment, the lcd panel 100 is disposed in the housing to form an lcd, and is used to display a certain electronic document on the lcd through a specific transmission device, and then reflect the electronic document to the display tool of human eyes.
Specifically, as shown in fig. 1, a driving circuit 31 is provided on the lower side of the liquid crystal display panel 100 to supply power to the liquid crystal display panel 100.

A gate electrode layer 12 is arranged on the array substrate 11; the color film substrate 21 is arranged on the array substrate 11 to form a liquid crystal box; the color filter substrate 21 is provided with a light-shielding layer 22 corresponding to the gate layer 12. When the light shielding layer 22 moves downward by 0 to 4 micrometers in the deformed dislocation state, reducing the length of the upper side of the gate layer 12 by 1 to 4 micrometers, that is, when the light shielding layer 22 is in a normal state, the length of the upper end part of the gate layer 12 is smaller than the length of the projection of the light shielding layer 22 on the array substrate 11 by 1 to 4 micrometers; the array substrate 11 is provided with a common electrode 13 on the upper side of the gate layer 12, and the projection of the light shielding layer 22 on the array substrate 11 is 1 to 4 micrometers in length, which is overlapped with one side of the common electrode 13 close to the gate layer 12. The length of the gate layer 12 at the upper side is shortened by 1 to 4 micrometers, the length of the common electrode 13 corresponding to the upper side is increased by 1 to 4 micrometers to the gate layer 12, and further the length of the projection of the light shielding layer 22 on the array substrate 11 and the overlapping length of the common electrode 13 at the side close to the gate layer 12 are 1 to 4 micrometers; when the light shielding layer 22 is dislocated, the liquid crystal corresponding to the dislocated position of the light shielding layer 22 is ensured not to be overturned, and light is prevented from transmitting out of the color film substrate 21 from the dislocated position of the light shielding layer 22.
The present invention proposes a second embodiment:
as shown in fig. 2, the present invention provides a liquid crystal display panel, wherein a common liquid crystal television is vertical and has a vertical direction in application, and the liquid crystal display panel 100 includes an array substrate 11 and a color filter substrate 21. A gate electrode layer 12 is arranged on the array substrate 11; the color film substrate 21 is arranged on the array substrate 11 to form a liquid crystal box; the color filter substrate 21 is provided with a light-shielding layer 22 corresponding to the gate layer 12. The deformed misalignment state is when the light shielding layer 22 moves upward or downward by 0 to 4 μm. Reducing the lengths of the upper side and the lower side of the original gate layer by 1 to 4 micrometers respectively, wherein the length range of the projection of the upper end part on the array substrate 11 away from the upper end of the light shielding layer 22 is 1 to 4 micrometers when the light shielding layer 22 is in a normal state; the range of the projection length of the lower end part from the lower end of the light shielding layer 22 on the array substrate 11 is 1 to 4 micrometers. By shortening the lengths of the two sides of the gate layer 12 by 1 to 4 micrometers respectively and further reducing the range of the overturned liquid crystal, the overturned liquid crystal can still be shielded when the light shielding layer 22 is in deformation dislocation; when the liquid crystal display panel 100 is in a dark state, the light-shielding layers 22 are displaced by pressing on the liquid crystal display panel 100, the projections of the displaced light-shielding layers 22 on the array substrate 11 can still cover the gate layers 12, and the inverted liquid crystal affected by the gate layers 12 is also completely covered by the displaced light-shielding layers 22, so that light transmitted through the inverted liquid crystal can only be irradiated onto the displaced light-shielding layers 22 and cannot be irradiated through the color filter substrate 21. The gate layer 12 is obtained by shortening the two sides of the original gate layer by 1 to 4 micrometers, that is, the lengths of the upper and lower sides of the gate layer 12 are both smaller than the length of the projection of the light shielding layer 22 on the array substrate 11 by 1 to 4 micrometers.

The present invention proposes a fourth embodiment:
as shown in fig. 7, when the liquid crystal display panel is in a dark state, a voltage is generated between the conventional gate layer and the common electrode on the color film substrate, so that the liquid crystal between the gate layer and the light-shielding layer is inverted, and light can be transmitted to the light-shielding layer through the inverted liquid crystal; when the liquid crystal display panel is subjected to external force, the color film substrate looses, the color film substrate is easy to move up and down, the shading layer can move along with the color film substrate in the up-and-down moving process, if the movement distance of the shading layer in the up-and-down direction is too large, the problem of light leakage can occur, light can be transmitted out from the upper side or the lower side of the shading layer, and the phenomenon of white cluster pressing in a dark state of the liquid crystal display panel is caused. As shown, the present invention provides a liquid crystal display panel, where the liquid crystal display panel 100 has an up-down direction when applied, and the liquid crystal display panel 100 includes an array substrate 11, a color film substrate 21, and two shielding layers 24; a gate electrode layer 12 is arranged on the array substrate 11; the color film substrate 21 and the array substrate 11 are enclosed to form a liquid crystal box; the color film substrate 21 is provided with a light-shielding layer 22 corresponding to the gate layer 12; the two shielding layers 24 are respectively arranged at the upper and lower sides of the light shielding layer 22; the shielding layer 24 is arranged on the upper side of the light shielding layer 22, so that the problem of white cluster pressing in a dark state can be prevented, a screen is subjected to certain pressure in the use process of the liquid crystal display panel, and the phenomenon of light leakage caused by the movement of the color film substrate 21 can be avoided; even if the color filter substrate 21 reciprocates in the up and down direction, light leakage does not occur.
