## Background
BACKGROUND OF THE DISCLOSURE
1. Field of the Disclosure
The present disclosure generally relates to a display panel and a pixel array thereof, and more particularly, to a display panel and a pixel array with a half source driver (HSD) structure including connecting portions of data lines which penetrate through sub-pixels.
2. Description of the Prior Art
With the improvement in liquid crystal display (LCD) technique, liquid crystal display has been prevalently used in electronic products such as flat panel TVs, laptop PCs, and mobile phones. The driving method of a conventional liquid crystal display utilizes source drivers and gate drivers to drive pixels in a display panel, and the cost of the source driver is higher than that of the gate driver. In order to reduce the number of the source drivers used in the liquid crystal display, a display panel with a half source driver (HSD) structure has been developed. For the same number of pixels, the half source driver structure has half number of the data lines of the source drivers and doubled number of the gate lines of the gate drivers, so as to reduce the manufacturing cost. In a pixel array of a conventional display panel with the half source driver structure, the data line is electrically connected with the active switching element of the corresponding pixel. Therefore, the circuit layout area between two adjoining gate lines of two adjoining pixel rows cannot be reduced, and the open ratio of the pixel cannot be effectively enhanced.

DETAILED DESCRIPTION
To provide a better understanding of the present disclosure to the skilled persons in the technology of the present disclosure, preferred embodiments will be detailed as follows. The preferred embodiments of the present disclosure are illustrated in the accompanying drawings with numbered elements to elaborate the contents and effects to be achieved.
Please refer to FIG. 1 and FIG. 2. FIG. 1 is a schematic diagram illustrating a pixel array according to a first embodiment of the present disclosure, and FIG. 2 is a schematic diagram illustrating a cross-sectional view of the pixel array taken along a line A-A′ in FIG. 1. As shown in FIG. 1 and FIG. 2, a pixel array 102 of this embodiment is disposed on an array substrate 100. The pixel array 102 includes a plurality of pixel rows 104, and each of the pixel rows 104 includes a first gate line 106, a second gate line 108, a plurality of sub-pixels 110 and a plurality of data lines 112. The first gate line 106 and the second gate line 108 are arranged alternately along a first direction D1 in sequence. The sub-pixels 110 are disposed between the first gate line 106 and the second gate line 108 and arranged along a second direction D2, wherein a portion of the sub-pixels 110 are electrically connected with the first gate line 106, and the other portion of the sub-pixels 110 are electrically connected with the second gate line 108. In this embodiment, the first direction D1 is the longitudinal direction in FIG. 1, and the second direction D2 is the lateral direction in FIG. 1, but not limited thereto.
Each of the data lines 112 includes a main portion 114, a branch portion 116 and a connecting portion 118. The main portions 114 of the data lines 112 are arranged along the second direction D2 in sequence, and the main portions 114 of the data lines 112 intersect the first gate line 106 and the second gate line 108. Specifically, the main portions 114 of the data lines 112 partially overlap the first gate line 106 and the second gate line 108 in the vertical projection direction Z. The branch portions 116 and the main portions 114 of the data lines 112 are arranged alternately along the second direction D2, and each of the sub-pixels 110 is disposed between any two of the main portion 114 and the branch portion 116 adjoining to each other. The connecting portion 118 of each of the data lines 112 is disposed between the first gate line 106 and the second gate line 108, the connecting portion 118 of each of the data lines 112 is electrically connected with the main portion 114 and the branch portion 116, and the connecting portion 118 of each of the data lines 112 penetrates through the sub-pixel 110 disposed between the main portion 114 and the branch portion 116 along the second direction D2. Thus, the main portion 114, the branch portion 116 and the connecting portion 118 of each of the data lines 112 may form an H-shaped structure, but not limited thereto. In this embodiment, the connecting portion 118 of each of the data lines 112, the first gate line 106 and the second gate line 108 in each of the pixel rows 104 may be parallel to one another, and the main portion 114 and the branch portion 116 of each of the data lines 112 in each of the pixel rows 104 may be parallel to each other, but not limited thereto. In addition, the branch portions 116 of the data lines 112 in each of the pixel rows 104 are disposed between the first gate line 106 and the second gate line 108 of the same pixel row 104. The pixel array 102 of this embodiment is a pixel array with a half source driver structure, and therefore a portion of the sub-pixels share the same data lines, so as to reduce the number of the data lines in the pixel array. What's more, in the pixel array 102 of this embodiment, the connecting portion 118 of each of the data lines 112 is electrically connected with the branch portion 116 and the main portion 114 and penetrates through the sub-pixel 110. Therefore, the branch portions 116 of the data lines 112 in the pixel array 102 of this embodiment can be electrically connected with the active switching elements 136 of two adjoining sub-pixels 110 without requiring the circuit layout area between the first gate line 106 of one of the pixel rows 104 and the second gate line 108 of another one of the pixel rows 104 adjoining thereto. Accordingly, the circuit layout area between the first gate line 106 of one of the pixel rows 104 and the second gate line 108 of another one of the pixel rows 104 adjoining thereto can be effectively reduced for enhancing the open ratio of the display panel. It is noteworthy that the efficiency of the liquid crystal in the region located in the middle of each of the sub-pixels 110 of the pixel array 102 is lower than other regions in each of the sub-pixels 110, and the connecting portion 118 of each of the data lines 112 of this embodiment can block the region in each of the sub-pixels 110 where the efficiency of the liquid crystal is low for further enhancing the total efficiency of the display panel.
In the pixel array 102 of this embodiment, the main portion 114 and the branch portion 116 of each of the data lines 112 are both V-shaped (non-straight) electrodes, rotated by 90 degrees in clockwise, but not limited thereto. In a variant embodiment, the main portion 114 and the branch portion 116 of each of the data lines 112 may be straight electrodes extending along the same direction (such as the first direction D1). It is noteworthy that the pixel rows 104 of this embodiment can include a first pixel row 132 and a second pixel row 134. The connecting portions 118 of the data lines 112 of the first pixel row 132 penetrate even-numbered sub-pixels 110 of the first pixel row 132, and the connecting portions 118 of the data lines 112 of the second pixel row 134 penetrate odd-numbered sub-pixels 110 of the second pixel row 134, but not limited thereto. In a variant embodiment, the connecting portions 118 of the data lines 112 of the first pixel row 132 may penetrate odd-numbered sub-pixels 110 of the first pixel row 132, and the connecting portions 118 of the data lines 112 of the second pixel row 134 may penetrate even-numbered sub-pixels 110 of the second pixel row 134.

In addition, the branch portion 116 of each of the data lines 112 is electrically connected with the source electrodes 144 of the active switching elements 136 of two sub-pixels 110 which are adjoining to the branch portion 116 in the second direction D2. For example, an end of the branch portion 116 of each of the data lines 112 may be electrically connected with the source electrode 144 of the active switching element 136 of one of the sub-pixels 110 which is adjoining to the branch portion 116, and the other end of the branch portion 116 of each of the data lines 112 may be electrically connected with the source electrode 144 of the active switching element 136 of the other one of the sub-pixels 110 which is adjoining to the branch portion 116, but not limited thereto.

In addition, the sub-pixels 110 may include sub-pixels providing light with different colors which may be mixed to present a full color display effect. The sub-pixels 110 may include red sub-pixels, green sub-pixels and blue sub-pixels for instance, and red sub-pixels, green sub-pixels and blue sub-pixels may be arranged in stripe, but not limited thereto. For example, in each of the pixel rows 104, (6n−5)th and (6n−2)th numbered sub-pixels 110 may be blue sub-pixels, (6n−4)th and (6n−1)th numbered sub-pixels 110 may be red sub-pixels and (6n−3)th and (6n)th numbered sub-pixels 110 may be green sub-pixels, and therefore light with different colors provided by the sub-pixels 110 may be mixed to present a full color display effect, but not limited thereto. In a variant embodiment, in each of the pixel rows 104, (6n−5)th and (6n−2)th numbered sub-pixels 110 may be red sub-pixels, (6n−4)th and (6n−1)th numbered sub-pixels 110 may be green sub-pixels and (6n−3)th and (6n)th numbered sub-pixels 110 may be blue sub-pixels. It is noteworthy that the driving method of the column inversion may be employed to the pixel array 102 of this embodiment, but not limited thereto.

The passivation layer 150 is disposed on the drain electrode 142, the source electrode 144, the channel layer 148 and the gate insulating layer 146. The passivation layer 150 may be a single-layered structure or a multi-layered structure. In this embodiment, the passivation layer 150 may be a double-layered structure. For example, a first passivation layer 152 and a second passivation layer 154 may stack in sequence to form the passivation layer 150 of this embodiment.

The pixel array 102 of this embodiment includes the passivation layer 150 which the thickness of the passivation layer 150 is about 2 micrometers, and therefore the parasitic capacitance between the data line 112 and the pixel electrode 138 can be effectively reduced. Furthermore, the pixel electrode 138 can be disposed to overlap the data line 112 in the vertical projection direction Z, the influence brought by the parasitic capacitance between the data line 112 and the pixel electrode 138 can be reduced, and the open ratio of the display panel can be effectively enhanced.
