Detailed Description
For better understanding of the objects, technical solutions and technical effects of the present invention, the present invention will be further explained with reference to the accompanying drawings and examples. Meanwhile, the following described examples are only for explaining the present invention, and are not intended to limit the present invention.
The embodiment of the invention provides a display panel:
fig. 2 is a schematic structural diagram of a display panel, and as shown in fig. 2, the display panel is applied to a display system having a half-source driving module, and includes:
the display device comprises a display array, a display unit and a control unit, wherein the display array comprises a plurality of first pixel columns D1 and second pixel columns D2 which are sequentially and alternately arranged, and the first pixel columns D1 and the second pixel columns D2 respectively comprise a plurality of pixels which are sequentially arranged in the column direction; the first pixel column D1 and the second pixel column D2 are paired and receive corresponding driving signals from the half-source driving module in a time-sharing manner;
the first pixel column D1 and the second pixel column D2 are respectively configured with different optical path differences, so that the respective pixels of the paired first pixel column D1 and second pixel column D2 have the same brightness when receiving different time-sharing portions of the same driving signal.
The pixel corresponding to the first pixel row D1 is A1, and the pixel corresponding to the second pixel row D2 is B1. The half-source driving signal of the display panel drives one of the first pixel row D1 or the second pixel row D2 first, and then drives the other row. When the positive and negative polarities of the driving signals are switched, the pixel array driven firstly does not reach the due potential, and the pixel array driven later can approach the ideal potential. If the pixel A1 in the first pixel column D1 is driven first, the potential of the pixel A1 in the first pixel column D1 is lower, the display luminance of the pixel A1 in the first pixel column D1 is lower than the display luminance of the pixel B1 in the second pixel column D2, and the display luminance of the first pixel column D1 is lower than the display luminance of the second pixel column D2 as a whole; if the pixel B1 in the second pixel column D2 is driven first, the potential of the pixel B1 in the second pixel column D2 is low, the display luminance of the pixel B1 in the second pixel column D2 is lower than the display luminance of the pixel A1 in the first pixel column D1, and the display luminance of the second pixel column D2 is lower than the display luminance of the first pixel column D1 as a whole. That is, the difference in the electric potentials of the pixels in the first pixel column D1 and the second pixel column D2 causes the difference in the display luminance of the first pixel column D1 and the second pixel column D2.
The first pixel column D1 and the second pixel column D2 are respectively configured with different optical path differences, that is, an absolute value of a difference between the optical path differences of the first pixel column D1 and the second pixel column D2 is greater than zero, and the absolute value of the difference exists, so that when the pixels of the first pixel column D1 and the second pixel column D2 receive different time-sharing portions of the same driving signal, a display luminance difference caused by the difference between the optical path differences can be compensated for, and the display luminance difference between the first pixel column D1 and the second pixel column D2 caused by the potential difference can be compensated.
In one embodiment, the first pixel column D1 and the second pixel column D2 are respectively configured with different pixel angles, so that an absolute value of an angle difference between the pixel angle of each pixel unit in the first pixel column D1 and 45 ° is different from an absolute value of an angle difference between the pixel angle of each pixel unit in the second pixel column D2 and 45 °, so that the first pixel column D1 and the second pixel column D2 respectively have different optical path differences. The pixel included angle is an included angle formed by a main electrode and a branch electrode in the pixel electrode.
Fig. 3 is a schematic diagram of pixel included angles, as shown in fig. 3, the pixel electrode uses an ITO transparent electrode as a Trunk electrode (Trunk) and a branch electrode (filt), when the ITO transparent electrode is driven by a proper driving voltage, the liquid crystal molecules nearby will generate a certain tilt angle along with the direction of the branch electrode, i.e. the pixel included angle, which is also the included angle between the Trunk electrode and the branch electrode, as shown in fig. 4
And (4) an angle.
The pixel included angle is in the range of 0-90 degrees, the corresponding pixel optical path difference is in normal distribution, namely when the pixel included angle is equal to 45 degrees, the corresponding optical path difference is the largest. Based on this, the optical path difference of the first pixel row D1 is greater than the optical path difference of the second pixel row D2, that is, the absolute value a of the angular difference between the pixel angle of the first pixel row D1 and 45 ° is smaller than the absolute value B of the angular difference between the pixel angle of the second pixel row D2 and 45 °, that is, a < B. Correspondingly, when B > a, the optical path difference of the second pixel row D2 is greater than the optical path difference of the first pixel row D1.
In one embodiment, the display panel comprises a liquid crystal display panel.
In one embodiment, the first pixel column D1 and the odd columns, and the second pixel column D2 is the even column; the optical path difference of the first pixel column D1 is greater than the optical path difference of the second pixel column D2.
In the liquid crystal display panel, different time-sharing parts of the half-source driving signals sequentially drive odd-numbered columns and even-numbered columns, wherein, as shown in fig. 2, different time-sharing parts of the same driving signal are driving signals corresponding to Pixel1 and Pixel2, namely different time-sharing parts of the same driving signal. When the first Pixel column D1 is an odd column, the driving signal corresponding to the first Pixel column D1 is a driving signal corresponding to Pixel 1; when the second Pixel column D2 is an even column, the driving signal corresponding to the second Pixel column D2 is the driving signal corresponding to the Pixel 2.
The potential of the driving signal corresponding to Pixel1 does not reach the potential of the driving signal corresponding to Pixel2, and therefore the display luminance of the first Pixel column D1 is lower than the display luminance of the second Pixel column D2. Therefore, the optical path difference of the first pixel row D1 is greater than the optical path difference of the second pixel row D2, and the larger optical path difference can improve the display brightness of the first pixel row D1 to compensate for the display brightness difference with the second pixel row D2 caused by the lower electric potential.
In one embodiment, an absolute value of an angle difference between an included pixel angle of each pixel unit in the first pixel column D1 and an included pixel angle of each pixel unit in the second pixel column D2 is greater than 2 ° and less than 5 °.
The absolute value of the angle difference between the pixel angle of each pixel unit in the first pixel row D1 and the pixel angle of each pixel unit in the second pixel row D2 is greater than 2 ° and less than 5 °, even if the difference between the optical path differences of the first pixel row D1 and the second pixel row D2 is limited within a specific range, so as to effectively eliminate the display brightness difference between the first pixel row D1 and the second pixel row D2, thereby improving the display quality of the display panel.
In one embodiment, the pixel included angle of each pixel unit in the first pixel column D1 is greater than 30 ° and less than 60 °, and the pixel included angle of each pixel unit in the second pixel column D2 is greater than 60 ° and less than 65 °.
Under the premise that the pixel included angle of each pixel unit in the first pixel row D1 is greater than 30 ° and less than 60 °, and the pixel included angle of each pixel unit in the second pixel row D2 is greater than 60 ° and less than 65 °, the following conditions should be satisfied: the absolute value of the angle difference between the pixel angle of each pixel unit in the first pixel row D1 and the pixel angle of each pixel unit in the second pixel row D2 is greater than 2 ° and less than 5 °. So as to effectively eliminate the display brightness difference between the first pixel row D1 and the second pixel row D2, thereby improving the display quality of the display panel.
In the display panel, the pixel units in the first pixel column D1 and the pixel units in the second pixel column D2 with different optical path differences are provided, so that the first pixel column D1 and the second pixel column D2 present the same brightness when receiving different time-sharing portions of the same driving signal. Therefore, under the driving of the actual driving signal, the display brightness difference between the first pixel row D1 and the second pixel row D2 is eliminated to eliminate the vertical bright and dark lines, so as to improve the display quality of the display.
The embodiment of the invention also provides a manufacturing method of the liquid crystal display panel, which comprises the following steps:
