The disclosure is further described in detail below with reference to the drawings and detailed description. It should be noted that the technical features of the embodiments of the present disclosure described below may be combined with each other as long as they do not collide with each other. The embodiments described below by referring to the drawings are exemplary and intended for the purpose of explaining the present disclosure and are not to be construed as limiting the present disclosure.

Example 1

As shown in fig. 1, the embodiment of the present disclosure provides a pixel structure 211 that can be used in a liquid crystal display panel 2. The pixel structure 211 may include a driving switch T1, a storage capacitor C, and a leakage switch T2.

The storage capacitor C may include a common electrode 2110 and a pixel electrode 2111 disposed opposite to each other, and it is understood that the common electrode 2110 is disposed in an insulating manner with respect to the pixel electrode 2111. The common electrode 2110 may be connected to a common signal terminal Acom, which may supply a common voltage to the common electrode 2110, and the common voltage supplied by the common signal terminal Acom during one frame period may be constant, for example, constant 0V, but is not limited thereto, and may be 1V, 5V, etc., as the case may be.

The control end of the driving switch tube T1 may be connected to the scan line 212, the first end of the driving switch tube T1 may be connected to the data line 213, and the second end of the driving switch tube T1 may be connected to the pixel electrode 2111, where the scan line 212 may be fed with a scan signal to control the driving switch tube T1 to be turned on, that is: the first end and the second end of the driving switch tube T1 are controlled to be in a conducting state, the first driving voltage carried on the data line 213 is sequentially charged into the pixel electrode 2111 through the first end and the second end of the driving switch tube T1, which can be also understood as charging into the storage capacitor C, because the charging of the pixel electrode 2111 can be completed in a short time, the duration of the charging conducting signal is very short, usually in a few microseconds to tens of microseconds, and then the scanning line 212 can be turned on with a turn-off signal to control the driving switch tube T1 to be turned off, and the first driving voltage on the data line 213 is charged completely, at this time, the voltage at the pixel electrode 2111 is the first driving voltage for driving the liquid crystal molecules to deflect, in other words, the pixel electrode 2111 is used for charging the first driving voltage provided by the data line 213 at the beginning of one frame period.

The control end and the first end of the leakage switch tube T2 may be connected to the pixel electrode 2111, the second end of the leakage switch tube T2 is connected to the common signal end Acom, and when the charging of the first driving voltage on the data line 213 is completed, the voltage at the pixel electrode 2111 is the first driving voltage, so that the voltage at the control end and the first end of the leakage switch tube T2 is also the first driving voltage, and the control end of the leakage switch tube T2 may respond to the first driving voltage to make the first end and the second end of the leakage switch tube T2 in a conducting state, that is: the leakage switch tube T2 is controlled to be turned on, at this time, the leakage switch tube T2 is in a leakage state, the leakage switch tube T2 can gradually reduce the voltage at the pixel electrode 2111 from the first driving voltage to the second driving voltage at the end of one frame period, at this time, the voltage at the control end of the leakage switch tube T2 can be the second driving voltage, and the leakage switch tube T2 can be turned off in response to the second driving voltage, that is: the control end of the leakage switch T2 may respond to the second driving voltage, so that the first end and the second end of the leakage switch T2 are in an off state, so as to ensure stability of the pixel structure 211.

In this embodiment, a leakage path is generated by disposing a leakage switching tube T2 on the pixel structure 211 to gradually decrease the first driving voltage charged into the pixel electrode 2111 by the data line 213 to the second driving voltage, so that when the voltage of the common electrode layer on the side of the liquid crystal molecules far from the pixel electrode 2111 is unchanged, in a frame period, since the first driving voltage on the pixel electrode 2111 gradually decreases to the second driving voltage, the liquid crystal molecules corresponding to the pixel electrode 2111 will deflect at different angles under different driving voltages, so that more than two kinds of liquid crystal molecules with different inclination angles can be obtained at different viewing angles to obtain more optical compensation in corresponding directions, namely: the display device obtains corresponding compensation under more different visual angles, realizes the display effect of wide visual angles and low color cast, simultaneously, the number of the switching tubes used by the pixel structure 211 is less, the layout area of the switching tubes in the liquid crystal display panel 2 is reduced, the light transmission area of the liquid crystal display panel 2 is increased, thereby improving the aperture ratio of the pixels, reducing the brightness and energy consumption of the backlight module and saving the production cost.

One frame period refers to the time between the rising edges (or falling edges) of the scan signals adjacent to the scan line 212.

For example, the driving switch transistor T1 and the leakage switch transistor T2 may be thin film transistors, for example, the driving switch transistor T1 and the leakage switch transistor T2 are both N-type thin film transistors, the scanning signal introduced into the scanning line 212 may be a high potential scanning voltage, the closing signal introduced into the scanning line 212 may be a low potential scanning voltage, the first driving voltage may be a high potential data voltage, and the second driving voltage may be a low potential data voltage, but the driving switch transistor T1 may be a P-type thin film transistor, the leakage switch transistor T2 may be an N-type thin film transistor, and so on, as the case may be.

In this embodiment, the pixel electrode 2111 may include a plurality of display domains (not shown) arranged according to a rule, and the display domains may have stripe electrodes arranged obliquely, where the oblique directions of the stripe electrodes of at least two display domains are different, so that the liquid crystal molecules corresponding to the pixel electrode 2111 have more tilt angles in the display process, and compensation in the corresponding directions can be obtained when the liquid crystal display panel 2 is viewed from different angles, thereby improving the viewing angle and facilitating the realization of the wide viewing angle display mode.

It should be noted that, the stripe electrodes in the display domain may be formed by patterning the pixel electrode 2111, or patterning an insulating layer under the pixel electrode 2111, where the protrusions and the depressions are staggered, and the pixel electrode 2111 is covered by the whole surface, so that the pixel electrode 2111 forms a plurality of stripe electrodes with different inclined settings by using the staggered protrusions and depressions of the insulating layer under the pixel electrode 2111.

For example, the pixel electrode 2111 may have four display domains arranged in an array in the row direction and the column direction, that is, the pixel structure 211 may have a 4-domain structure, wherein the inclination directions of the stripe electrodes arranged in the two display domains are different in the row direction and the inclination directions of the stripe electrodes arranged in the two display domains are different in the column direction, so that the compensation in the corresponding direction can be obtained when the liquid crystal display panel 2 is viewed from more different angles, and the pixel structure 211 may have the advantages of being insensitive to the line/space (line/space) of the pixel electrode 2111, and reducing the manufacturing difficulty of the pixel electrode 2111.

The whole strip electrodes of the four display domains can be regarded as being distributed in an X shape, and the whole pixel electrode 2111 can be regarded as being in a shape like a Chinese character 'mi', so that the design and processing difficulty of the pixel electrode 2111 are reduced.

It should be understood that the display domains in the pixel electrode 2111 may be four display domains, or may be two display domains, six display domains, eight display domains, or other numbers of display domains.

Further, in order to secure the display effect, the absolute value of the ratio of the second driving voltage to the first driving voltage should be at least 40% or more, and if the display effect of the wide viewing angle is to be achieved, the absolute value of the ratio of the second driving voltage to the first driving voltage should be also 70% or more.

Taking the pixel structure 211 as a 4-domain structure as an example, when the absolute value of the ratio of the second driving voltage to the first driving voltage is greater than or equal to 70%, the pixel structure 211 can achieve the display effect of the related art 8-domain structure, but compared with the related art 8-domain structure, the circuit design is simplified, and the number of switching transistors is specifically reduced, for example: in the related art, the 8 domain structure generally includes 3 switching tubes, and the pixel structure 211 of the present embodiment includes only 2 switching tubes, so the layout area of the switching tubes in the lcd panel 2 can be reduced by designing the embodiment in this way, so that the light transmission area of the lcd panel 2 is increased, and the pixel aperture ratio can be improved, so that the brightness and energy consumption of the backlight module can be reduced, and the production cost can be saved.

It should be appreciated that the present embodiment actually defines the size of the leakage driving transistor by defining the ratio of the first driving voltage and the second driving voltage, and the smaller the absolute value of the ratio of the second driving voltage to the first driving voltage is as the width-to-length ratio of the transistor is larger.

The present embodiment provides an array substrate 21, where the array substrate 21 includes a substrate 210, and scan lines 212, data lines 213 and pixel structures 211 mentioned in the first embodiment formed on the substrate 210, the scan lines 212 may be regarded as extending in the row direction as a whole, and the data lines 213 may be regarded as extending in the column direction as a whole.

The structure of the array substrate 21 according to the embodiment of the present disclosure will be described in detail with reference to fig. 2 and 3.

The substrate 210 may be a glass substrate, but not limited thereto, and may be a substrate made of other materials, such as PI material, etc.

Taking the driving switching transistor T1 and the leakage switching transistor T2 as the bottom gate thin film transistor as an example, a first electrode layer, a first insulating layer 214, an active layer, a second electrode layer, a second insulating layer 215, and a third electrode layer may be sequentially formed on the substrate 210.

When the first electrode layer is made of a metal or alloy material, the common electrode 2110 may be designed in a wire frame shape in order to secure light transmission performance.

The active layer may include a first active portion 218 and a second active portion 219, where the first active portion 218 is disposed opposite to the first gate 216, and the second active portion 219 is disposed opposite to the second gate 217, and the first active portion 218 and the second active portion 219 may be disconnected from each other or may be connected together, as the case may be.

The second electrode layer may include a data line 213 and first, second and third electrode parts 220, 221 and 222 disconnected from each other, the first electrode part 220 including a first end of the driving switching tube T1 and being interconnected with the first active part 218 and the data line 213, the second electrode part 221 including a second end of the driving switching tube T1 and a first end of the leakage switching tube T2 and being interconnected with the first and second active parts 218 and 219, the third electrode part 222 including a second end of the leakage switching tube T2 and being interconnected with the second active part 219, and the third electrode part 222 also being interconnected with the common electrode 2110 through at least a first via structure 223 penetrating the first insulating layer 214, that is, the second end of the leakage switching tube T2 may be connected with the peripheral common signal terminal Acom through the common electrode 2110 to simplify the design.

For example, the second electrode layer may be made of metal or alloy materials, such as molybdenum, aluminum, titanium, etc., to ensure good electrical conductivity, but is not limited thereto, and may be made of other materials with good electrical conductivity.

The third electrode layer may include at least the pixel electrode 2111, the pixel electrode 2111 is interconnected with the second electrode portion 221 through the second via structure 224 penetrating the second insulating layer 215, and the pixel electrode 2111 is also connected with the second gate electrode 217 through the third via structure 225 penetrating the second insulating layer 215 and the first insulating layer 214.

Wherein, when the common electrode 2110 is designed in a wire frame shape, an edge of the pixel electrode 2111 may overlap with the wire frame of the common electrode 2110 in a direction perpendicular to the substrate 210 to form the storage capacitance C.

It will be appreciated that the orthographic projection of the display domains of the pixel electrodes 2111 on the substrate 210 is located within the wire frame of the common electrode 2110.

Further, the third electrode layer may be made of ITO (indium tin oxide) material to improve light transmittance, but is not limited thereto, and may be made of other transparent conductive materials.

For example, the third electrode layer may further include a transfer electrode 226 disconnected from the pixel electrode 2111, the first via structure 223 may further include a first transfer hole 2230 penetrating the second insulating layer 215 and a second transfer hole 2231 penetrating the second insulating layer 215 and the first insulating layer 214, the first transfer hole 2230 and the second transfer hole 2231 may be spaced apart from each other, the transfer electrode 226 may be connected to the third electrode part 222 through the first transfer hole 2230, and the transfer electrode 226 may be connected to the common electrode 2110 through the second transfer hole 2231.

Illustratively, the orthographic projection of the third via structure 225 on the substrate 210 is located in the orthographic projection of the second active portion 219 and the second electrode portion 221 on the substrate 210, and the third via structure 225 penetrates the second active portion 219 and the second electrode portion 221 and is insulated from the second active portion 219 and the second electrode portion 221 by the second insulating layer 215, so that the design can avoid the third via structure 225 occupying an additional panel space, and thus the aperture ratio can be improved.

It should be noted that the driving switch tube T1 and the leakage switch tube T2 in the embodiments of the present disclosure are not limited to the bottom gate type mentioned above, but may be a top gate type, which is not specifically described herein.

The lcd panel 2 of this embodiment can be in a PVA (Patterned Vertical Alignment) wide viewing angle mode, in which the long axes of the liquid crystal molecules 23 are perpendicular to the substrate 210 when no voltage is applied, and each pixel structure 211 is formed by a plurality of such vertically aligned liquid crystal molecules 23, and when a voltage is applied to the liquid crystal molecules 23, the liquid crystal molecules 23 are tilted in different directions, so that compensation in the corresponding directions can be obtained when viewing the panel from different angles, and the viewing angle is improved. The PSVA technology is to add a specific substance RM into the liquid crystal, and after the specific UV (ultraviolet) light is irradiated, the liquid crystal molecules 23 form a certain pretilt angle and are orderly arranged, so as to realize a wide viewing angle display mode similar to PVA, but without newly placing a bump structure or ITO scribe lines on the upper and lower substrates.
