Fig. 5 and fig. 6 are partial schematic views of a pixel electrode according to a preferred embodiment of the invention. Here, fig. 5 and fig. 6 are the same views, and only the differences are labeled with reference numerals to describe the features of the pixel electrode in detail. As shown in fig. 5 and 6, the pixel electrode of the present embodiment includes: a first finger 51 having a first inner edge 511 and a third outer edge 512 on a side opposite to the first inner edge 511; a second finger 52 having a second inner edge 521 and a first outer edge 522 on a side opposite to the second inner edge 521, the second inner edge 521 being located between the first inner edge 511 and the first outer edge 522; a contact portion 53 electrically connected to the pixel switch 3123 (shown in fig. 4) through a contact hole 3124a, and the contact portion 53 is further disposed in the contact hole 3124a to electrically connect to the drain 3123d (shown in fig. 4) of the pixel switch 3123; a first bending part 54 located between the first finger 51 and the contact part 53 and connecting the first finger 51 and the contact part 53, the first bending part 54 having a third inner edge 541 and a fourth outer edge 542 at a side opposite to the third inner edge 541; and a second bending portion 55 located between the second finger portion 52 and the contact portion 53 and connecting the second finger portion 52 and the contact portion 53, the second bending portion 55 has a fourth inner edge 551 and a second outer edge 552 on a side opposite to the fourth inner edge 551, and the fourth inner edge 551 is located between the third inner edge 541 and the second outer edge 552.
As shown in fig. 5, in the pixel electrode of the display panel of the present embodiment, a first included angle θ 1 is formed between the extension line of the first inner edge 511 and the third inner edge 541, a second included angle θ 2 is formed between the extension line of the first outer edge 522 and the second outer edge 552, and the first included angle θ 1 is smaller than the second included angle θ 2. In addition, as shown in fig. 6, the third inner edge 541 and a straight line parallel to a first direction X have a first acute angle θ a, the second outer edge 552 and the straight line have a second acute angle θ b, the first direction X is substantially parallel to an extending direction of a gate line 3121 (shown in fig. 3), and the first acute angle θ a is greater than the second acute angle θ b. By designing the first included angle θ 1 to be smaller than the second included angle θ 2 or/and the first acute angle θ a to be larger than the second acute angle θ b, the second outer edge 552 is closer to the third inner edge 541, so that the dark fringes generated by the display panel in the bright state can be closer to the area adjacent to the contact portion 53, and the liquid crystal efficiency in the area can be improved. Wherein, the difference between the first included angle theta 1 and the second included angle theta 2 can be between 1 and 10 degrees; the difference between the first acute angle thetaa and the second acute angle thetab may be between 1 and 10 degrees. Herein, the phrase "the first direction is substantially parallel to a gate line extending direction" means that an angle between the first direction and the gate line extending direction is 0 to 5 degrees, and preferably 0 degree; the terms "first acute angle" and "second acute angle" refer to an included angle between 0 and 90 degrees.
In addition, as shown in fig. 5, in the pixel electrode of the display panel of the embodiment, the second finger portion 52 has a first width W1 in the first direction X, the second bending portion 55 has a second width W2 in the first direction X, and the first width W1 is greater than the second width W2. Similarly, the first width W1 is designed to be larger than the second width W2, so that the width of the second bending portion 55 near the contact portion 53 can be reduced, thereby further reducing the dark fringes generated when the display panel is in a bright state.
Furthermore, as shown in fig. 5, in the pixel electrode of the display panel of the present embodiment, a finger gap 57 is formed between the first inner edge 511 and the second inner edge 521, a bending gap 56 is formed between the third inner edge 541 and the fourth inner edge 551, and the bending gap 56 is located between the finger gap 57 and the contact portion 53 and connects the finger gap 57 and the contact portion 53. The second bending portion 55 has a first length L1 in a second direction Y, the bending portion gap 56 has a second length L2 in the second direction Y, the second direction Y is substantially perpendicular to an extending direction of a gate line 3121 (as shown in fig. 3), and the first length L1 is substantially equal to the second length L2. Herein, the phrase "the second direction is substantially perpendicular to an extending direction of the gate line" means that an included angle between the second direction and the extending direction of the gate line is 85 to 90 degrees, and preferably 90 degrees; in addition, the phrase "the first length is substantially equal to the second length" means that the variation between the first length and the second length is 0 to 5%.
In addition, as shown in fig. 5, in the pixel electrode of the display panel of the present embodiment, the finger gap 57 has a third width W3 in the first direction X, the bent portion gap 56 has a fourth width W4 in the first direction X, and the third width W3 is smaller than the fourth width W4. Similarly, the third width W3 is designed to be smaller than the fourth width W4, so that the width of the second bending portion 55 near the contact portion 53 can be reduced, thereby further reducing the dark fringes generated when the display panel is in a bright state.
As shown in fig. 6, in the pixel electrode of the display panel of the present embodiment, the first outer edge 522 to the third outer edge 512 have a first distance D1 in the first direction X, the contact portion 53 has a fifth width W5 in the first direction X, and the first distance D1 is smaller than the fifth width W5. In addition, the second to fourth outer edges 552 to 542 have a second distance D2 in the first direction X, and the second distance D2 is smaller than the fifth width W5. For the purpose of high pixel density, the size of a single pixel region must be reduced; however, the contact hole 3124a cannot be simultaneously reduced. Therefore, in order to avoid the dark fringes caused by the irregular tilting direction of the liquid crystal between the contact portion 53 and the second bending portion 55, the first distance D1 and the second distance D2 are respectively designed to be smaller than the fifth width W5, so that the dark fringes of the display panel in the bright state are closer to the area adjacent to the contact portion 53, and the liquid crystal efficiency of the area is further improved.
Furthermore, as shown in fig. 6, in the pixel electrode of the display panel of the present embodiment, the first distance D1 is also designed to be greater than the second distance D2; therefore, the width of the second bending portion 55 near the contact portion 53 can be reduced, so as to further reduce the dark fringes generated when the display panel is in a bright state.
In order to verify that the display panel manufactured by the foregoing embodiment of the invention indeed has better liquid crystal efficiency, the display panel shown in fig. 2 is used for testing, and the liquid crystal efficiency when the first included angle θ 1 and the second included angle θ 2 in the pixel electrode have different differences as shown in fig. 5 is compared. Here, the "liquid crystal efficiency" refers to the emission intensity per unit area.
When a voltage of 0 to 8V is applied to the display panel shown in fig. 2, under the condition that the first included angle θ 1 is equal to the second included angle θ 2 (the difference between the first included angle θ 1 and the second included angle θ 2 is 0 degrees), and the first included angle θ 1 is smaller than the second included angle θ 2, and the differences between the first included angle θ 1 and the second included angle θ 2 are 2, 3, 4, and 5 degrees, respectively, the liquid crystal efficiency of the pixel electrode in the area shown in fig. 5 is as shown in fig. 7. Particularly, when the difference between the first included angle θ 1 and the second included angle θ 2 is 0 degrees, the liquid crystal efficiency of the pixel electrode in the region shown in fig. 5 is 0.048643%; when the difference between the first included angle θ 1 and the second included angle θ 2 is 5 degrees, the liquid crystal efficiency of the pixel electrode in the region shown in fig. 5 is 0.051924%; after calculation, compared with the case that the difference between the first included angle θ 1 and the second included angle θ 2 is 0 degree, when the difference between the first included angle θ 1 and the second included angle θ 2 is 5 degrees, the gain of the liquid crystal efficiency can reach 6.75%. This result shows that when the width of the second bending portion 55 (as shown in fig. 5) is reduced to make the first included angle θ 1 smaller than the second included angle θ 2, that is, the second outer edge 552 is closer to the first bending portion 54, the liquid crystal efficiency in this area can be significantly improved.
Here, the dark fringe pattern of the part of the pixel electrode shown in fig. 5 in the bright state is further simulated; the result is shown in fig. 8, which is a simulation result diagram of the display panel shown in fig. 2, comparing that the first included angle θ 1 in the pixel electrode shown in fig. 5 is equal to the second included angle θ 2 (the difference between the first included angle θ 1 and the second included angle θ 2 is 0 degrees), and the first included angle θ 1 is smaller than the second included angle θ 2, and the difference between the first included angle θ 1 and the second included angle θ 2 is 5 degrees in the bright state.
As shown in fig. 8, compared to the case that the first included angle θ 1 is equal to the second included angle θ 2, when the first included angle θ 1 is smaller than the second included angle θ 2 and the difference between the first included angle θ 1 and the second included angle θ 2 is 5 degrees, on the same reference line, the reference line is the first direction X substantially parallel to the extending direction of a gate line 3121 (as shown in fig. 3), the dark fringe width in the bright state can be significantly reduced (as shown by arrows), and the stability of the liquid crystal molecules in this region is improved.
In summary, in the embodiment, by designing the first included angle to be smaller than the second included angle, the second outer edge of the second bending portion is closer to the fourth inner edge and the third inner edge of the first bending portion, so that the dark stripes generated by the display panel in the bright state can be reduced, and the dark stripes can be closer to the area adjacent to the contact portion, thereby improving the liquid crystal efficiency in the area.
In the foregoing embodiments of the present invention, the terms "width", "distance" and "length" refer to "minimum width", "shortest distance" and "shortest length" between two edges, respectively; the term "angle" refers to the "maximum angle" between the two edges, the extension thereof, and/or the reference line.
In the foregoing embodiments of the present invention, the pixel electrode includes two finger portions and a bending portion as an example; however, in other embodiments of the present invention, the pixel electrode may include more than three finger portions and bending portions, as long as the finger portion and the bending portion (the rightmost finger portion and the bending portion in the view of fig. 3) farthest from the tft unit in the same pixel have the above-mentioned features.
In addition, in the embodiments of the present invention, the display panel with a horizontal alignment is taken as an example; however, in other embodiments of the present invention, the display panel is a vertically aligned liquid crystal display panel.
Furthermore, the display panel manufactured by the foregoing embodiments of the invention can also be used in combination with a touch panel known in the art as a touch display device. Meanwhile, the display panel or the touch display device manufactured in the foregoing embodiment of the invention may be applied to any electronic device that needs a display screen and is known in the art, such as a display, a mobile phone, a notebook computer, a video camera, a music player, a mobile navigation device, a television, and the like.
