Rather, these embodiments are provided so that this disclosure will be thorough and complete.
It will be understood that when an element is referred to as being "connected" to another element, it can be directly connected to the other element and be integral therewith, or intervening elements may also be present. The terms "mounted," "one end," "the other end," and the like are used herein for illustrative purposes only.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
The embodiment of the invention provides a display panel, which comprises a substrate, scanning lines, first data lines and second data lines, wherein the first data lines are perpendicular to the scanning lines, the second data lines are perpendicular to the scanning lines, and the first data lines and the second data lines are arranged in parallel at intervals; the scanning lines, the first type data lines and the second type data lines are staggered to form a plurality of pixel regions which are arranged in an array shape, and a plurality of active array switches which are arranged in an array shape are arranged on the substrate corresponding to the pixel regions; a plurality of pixel units are correspondingly arranged along the extending direction of the first type of data lines, wherein one part of the pixel units comprise at least one active array switch, and the other part of the pixel units comprise at least two active array switches; each active array switch of one of the two adjacent pixel units in the extending direction of the data line is connected with the first type of data line, and each active array switch of the other pixel unit is connected with the second type of data line; when the pixel units corresponding to the scanning lines are started, the starting time is the starting time, the data polarity loaded by each first-type data line at two adjacent starting times is opposite, and the data polarity loaded by each second-type data line at two adjacent starting times is opposite; and at the same starting time, the loaded data polarities of the first type data lines and the second type data lines are opposite.
The substrate is a substrate with an epitaxial layer, and plays a role in supporting and fixing in the production and manufacturing processes of the substrate. The active array switch is a transistor disposed in each pixel region for driving the pixel electrode. For example, the active array switch may be a thin film transistor or the like. The scanning lines, the first-type data lines and the second-type data lines may be staggered to form a plurality of pixel regions arranged in an array, as shown in fig. 1, where two adjacent data lines and two adjacent scanning lines surround each other to form a region. The turn-on time refers to a time when a gate driving signal is applied to a certain row of scan lines, and driving each active array switch connected to the scan lines to switch the first type data line and the second type data line means that the data polarities applied to the first type data line and the second type data line are opposite at the same turn-on time, for example, at the same turn-on time, the data polarity applied to the first type data line is positive, and at this time, the data polarity applied to the second type data line is negative, it should be noted that the data polarity of the first type data line (the second type data line) is not limited to be a fixed state, and at two adjacent turn-on times, the polarity of the first type data line (the second type data line) is inverted.
Specifically, the plurality of scanning lines are respectively arranged in a manner of crossing with the first type data lines and the second type data lines, and the scanning lines cross and surround the active array switches in the plurality of pixel regions. The active array switches are sequentially arranged along the extension direction of the scanning line, and the active array switches are also sequentially arranged along the extension direction of the first type of data line, namely the active array switches are arranged in an array shape. The active array switches arranged on the substrate are grouped into different pixel units, one part of the pixel units comprise at least one active array switch, the other part of the pixel units comprise at least two active array switches, and the pixel units arranged along the extension direction of the first-class data lines are alternately connected to the adjacent first-class data lines and the second-class data lines.
At this time, if the polarity of the data loaded on the first type data line is positive and the polarity of the data loaded on the second type data line is negative at a turn-on time, the polarities of the pixel units in each column arranged along the extending direction of the first type data line are correspondingly positive and negative, and the active array switches in the pixel units in each column are loaded to the deflection voltages of the corresponding liquid crystal molecules to be positive or negative under the driving of the data with the corresponding polarities. The pixels corresponding to the active array switches arranged along the extension direction of the first-class data line are displayed at intervals of positive and negative polarities, so that high-quality display image quality can be ensured in a column inversion driving mode, the output voltage range of the pixel electrode can be reduced, power consumption is reduced, and cost is saved.
In an exemplary technique, the pixel arrangement shown in fig. 2 is often adopted, and if the display quality is ensured under the pixel setting rule, for example, the polarity of the target is arranged to be "+ - - - - - + …" when displaying for each pixel corresponding to the data line D1, the data line D1 needs to carry the data signal shown in fig. 3, so that the polarities of other adjacent data lines D2 and D3 are arranged as shown in fig. 2 when displaying for each pixel on the panel at the turn-on time (i.e., the scan lines G1 to Gm are correspondingly turned on), so as to ensure the display quality. At the next turn-on time, taking the data signal of the data line D1 as an example, it needs to be inverted to "- ++++ - …", which consumes more power.
Fig. 1 is taken as an example to better illustrate the working principle of the display panel provided by the embodiment of the invention. Taking the first type data line D1 'and the second type data line D2' adjacent thereto as an example, pixel cells (pixel cells P1, P3, and P4) arranged two by two along the extending direction of the first type data line are respectively connected to the adjacent first type data line D1 '(pixel cell P1 and pixel cell P4) and second type data line D2' (pixel cell P3), if the first type data line D1 'is loaded with data with positive data polarity and the second type data line D2' is loaded with data with negative data polarity (as shown in fig. 4) at a turn-on time, the display polarity of the pixel region corresponding to the row of active array switches between the first type data line D1 'and the second type data line D2' is sequentially "+ - - - - - + + …" from top to bottom as shown in fig. 1. Under the column inversion driving mode, the energy consumption can be greatly reduced on the premise of ensuring the pixel display polarity requirement under high image quality.
In one embodiment, as shown in fig. 1, the number of active array switches in each pixel unit adjacent to each other in the extending direction of the scan line is equal, and each active array switch in one of two pixel units adjacent to each other in the extending direction of the scan line is connected to the first type data line, and each active array switch in the other pixel unit is connected to the second type data line.
Two adjacent pixel units along the extension direction of the scanning line are respectively connected with the first type data line and the second type data line, so that the polarities of the data loaded by the pixel units along the extension direction of the scanning line are opposite, and the display polarities are opposite. For example, as in the pixel cell P1 and the pixel cell P2 in fig. 1, if the polarity of the data applied to the pixel cell P1 connected to the first data line D1 'is positive and the polarity of the data applied to the pixel cell P2 connected to the second data line D2' is negative at a turn-on time, the display polarities of the active array switches in P1 and P2 are opposite at the turn-on time, so that the display effect at a large viewing angle is improved. And two adjacent data lines are adopted to load data signals with different data polarities, so that the anti-interference performance in the data loading process can be improved, and the display image quality and the display stability can be improved.
In one embodiment, the number of active array switches connected with the first type data line in four adjacent pixel units along the extension direction of the first type data line is the same as the number of active array switches connected with the second type data line.
In order to ensure the display effect under a large viewing angle and avoid color cast display under the large viewing angle, in the display panel provided by the embodiment of the invention, in four adjacent pixel units along the extending direction of a first row of data lines, the number of active array switches of a first type of data lines is the same as that of active array switches connected to a second type of data lines, so as to ensure a pixel block formed by the four pixel units, when the display is started, the positive polarity and the negative polarity of the pixel display can be mutually offset, the color cast problem of the display panel during the display is effectively improved, and the display image quality under the large viewing angle is improved.
For example, as shown in fig. 5, the arrangement of the active array switch in fig. 5 is taken as an example, where "1" denotes an active array switch connected to a first type of data line of the data lines adjacent to the left and right sides thereof, and "2" denotes an active array switch connected to a second type of data line of the two data lines adjacent to the left and right sides thereof. If the polarity of the data loaded on the first-type data lines D1 ', D3', D5 ', D7', D9 'and D11' is "+" and the polarity of the data loaded on the second-type data lines D2 ', D4', D6 ', D8', D10 'and D12' corresponding to the first-type data lines is "-" at an on time, the display polarities of the pixel regions corresponding to the data lines are arranged as shown in fig. 6. Similarly, at the next turn-on time, after the polarity of each data line is inverted, the display polarity arrangement of the pixel region corresponding to each data line is changed to that shown in fig. 7.
In one embodiment, the number of active array switches in the pixel unit along the extending direction of the first type data line is sequentially cycled according to 1, 4 and 1. With this pixel cell arrangement, it is possible to realize the display with the reverse pixel display polarity mounting method of 1+4 as shown in fig. 6 and 7 in the column inversion driving method.
In one embodiment, the display panel further includes a color filter disposed corresponding to the substrate, the color filter includes a red color filter, a green color filter, and a blue color filter disposed corresponding to each pixel region, the color filters along the extension direction of the scan lines are cyclically arranged according to the sequence of the red color filter, the green color filter, and the blue color filter, and the color filters along the extension direction of the first type data lines are cyclically arranged according to the sequence of the red color filter, the green color filter, and the green color filter.
In order to further improve the display image quality of the display panel, the display effect under a large viewing angle is improved. The display panel provided by the embodiment of the invention also comprises a color filter plate arranged corresponding to the substrate, wherein the corresponding relation is that one color resistance on the color filter plate corresponds to one pixel area on the substrate, and the two color resistances are in one-to-one correspondence. After the color filter plate and the substrate are arranged correspondingly, when each pixel area on the substrate displays, the color filter plate can display the color which is the same as the color resistance color corresponding to the pixel area. The color resistors on the color filter plate are sequentially and circularly arranged according to the color sequence of red, green and blue along the extending direction of the scanning line, and each row of color resistors are arranged according to the color sequence of red, blue and green along the extending direction of the first type of data line. By adopting the color resistance arrangement mode, the color cast under a large visual angle can be reduced, and the pixel display quality is improved.
In one embodiment, the active array switch includes a gate and a pixel electrode, the pixel electrode is connected to the data line, and the gate is connected to the scan line. The gate of each active array switch is connected to the corresponding scan line, and the pixel electrode of each active array switch is connected to the corresponding first-type data line or second-type data line according to the rule in the above embodiment. When the scanning lines load the gate opening signals, the corresponding active array switches are opened, at the moment, the pixel electrodes of the opened active array switches receive the data signals transmitted by the first-type data lines or the second-type data lines, and voltage difference is formed between the pixel electrodes and the common electrode to drive liquid crystal to deflect, so that display is realized. The common electrode is a port on the display panel for providing a common voltage for display.
In one embodiment, the active array switch adopts a column inversion driving mode, and the display panel further comprises a data driving unit; at two adjacent starting moments, the data driving unit is respectively used for providing a first gray scale voltage and a second gray scale voltage for the pixel electrode of the active array switch; the polarity of the first gray scale voltage relative to the common voltage is opposite to that of the second gray scale voltage relative to the common voltage; the common voltage is a voltage loaded on the common electrode of the pixel corresponding to the active array switch.
In one embodiment, the pixel region is divided into a main pixel region and a sub-pixel region which are arranged at intervals, a first type of gray scale voltage is loaded on a pixel electrode of an active array switch corresponding to the main pixel region, a second type of gray scale voltage is loaded on a pixel electrode of an active array switch corresponding to the sub-pixel region, and the first type of gray scale voltage is larger than the corresponding second type of gray scale voltage.
One main pixel region may correspond to one unit pixel, and one sub-pixel region may correspond to one unit pixel. One main pixel region may correspond to one sub-pixel, and one sub-pixel region may correspond to one sub-pixel.
With the active matrix switch arrangement provided in the above embodiment, if the data signals shown in fig. 8 are adopted, the display polarity arrangement shown in fig. 9 is provided, and it is easy to observe that, in a pixel block composed of a certain unit pixel, for example, each unit pixel composed of three rows of sub-pixels between the data lines D1 '-D4', specifically, the RGB unit pixel 1 shown in fig. 10 (RGB unit pixel 1 refers to a pixel unit including sequentially arranged red sub-pixel, green sub-pixel and blue sub-pixel), wherein the pixel areas in fig. 9 and 10 correspond to each other in sequence, and for 12 RGB unit pixels 1 located in the main pixel area in fig. 10, the display polarities of each RGB unit pixel 1 are + -, + -, and- + -, so that the polarities of the red sub-pixels exactly cancel each other, the display polarity of the green sub-pixel also exactly cancels out, and similarly, the display polarity of the blue sub-pixel also exactly cancels out. Similarly, for the 12 adjacent GBR unit pixels 3 in the main pixel region 11 in fig. 10, the display polarities of the GBR unit pixels 3 are- + -, + - +, + -, respectively, so that the display polarities of the sub-pixels of each color just cancel each other out; for 12 BRG unit pixels 2 located in the main pixel region, the display polarities of the BRG unit pixels 2 are- + -, - + -, + -and+ - + -, respectively, so the display polarities of the sub-pixels of each color can be exactly offset, and no color shift is generated, and the display panel has good display effect. The sub-pixel region 12 in fig. 10 also meets the above-mentioned polarity cancellation phenomenon, and the display effect at a large viewing angle can be improved.
Similarly, as shown in fig. 11, when the column of sub-pixels between the first data line D1 'and the second data line D2' is used as an object, it is easy to know that, for 12 adjacent sub-pixels located in the main pixel region 110, the display polarities corresponding to the red sub-pixels are sequentially + → + → - → -, so that the polarities can just cancel each other; similarly, the display polarities of the green sub-pixels are sequentially- → + → + → + → -, so that the polarities just cancel each other out, and for the blue sub-pixels, the display polarities are sequentially- → - → + → +, and the polarities just cancel each other out. The polarity cancellation rule described above is also satisfied for the sub-pixel region 120 in fig. 11.
The display panel provided by the embodiment of the invention can support two driving modes of carrying out main and sub-pixel area division by taking the unit pixel as a unit and carrying out main and sub-pixel area division by taking the sub-pixel as a unit, and no matter which main and sub-pixel area division rule is adopted, the display panel has no color cast when displaying.
In one embodiment, the active array switch is a thin film transistor.
A display device includes a control part 100 and the display panel 200. As shown in fig. 12, in the display device according to the embodiment of the invention, the control unit 100 sends the driving signal to the display panel 200, and the gate is turned on through the scan line on the display panel 200. And then, a column inversion driving mode is adopted, the data signals for display are transmitted through the first type data lines and the second type data lines, and the pixel regions corresponding to the active array switches on the control substrate 220 are displayed in a positive and negative display polarity interval mode when displaying, so that the electric energy is saved, and the loss is reduced.
