Problems solved by technology

However, due to the increase in the size of the display panel and the increase in the signal transmission frequency, the crosstalk effect is enhanced, so the distance d2 must be increased accordingly.
Similarly, the distance d1 of the scanning line 1 must also be increased, which further leads to a decrease in the aperture ratio and affects the brightness performance

Embodiment 1

[0058] Please refer to Figure 2A, which is a schematic diagram of a pixel structure according to Embodiment 1 of the present invention. The pixel structure 100 includes scan lines 110 , data lines 120 , thin film transistors 130 , pixel electrodes 140 and storage capacitors 150 . The thin film transistor 130 is disposed on the scan line 110, and a part of the scan line 110 is used as the gate 130e of the thin film transistor 130 to control its switching. The data line 120 is coupled to the source 130a of the thin film transistor 130. When an appropriate voltage is applied to the scanning line 110, the signal can be transmitted through the channel layer 130b, and output from the drain 130c to the pixel electrode 140 through the contact hole 130d. The storage capacitor 150 is coupled to the pixel electrode 140 through the contact hole 150 a for maintaining the voltage of the pixel electrode 140 .

Embodiment 2

[0080] Please refer to Figure 7A , which is a schematic diagram of a pixel structure in Embodiment 2 of the present invention. The main difference between the pixel structure 200 and the pixel structure 100 of the first embodiment lies in the types of the contact holes in the scan line 210 and the data line 220, and the rest of the elements are the same as those of the first embodiment, and their labels will continue to be used and will not be repeated. The link is off.

[0081] Please refer to Figure 7B , which shows Figure 7A The cross-sectional view of the middle scan line along the section line EE'. The first scanning insulating layer 213 and the second scanning insulating layer 217 respectively have a first contact hole 210a and a second contact hole 210b, and the third scanning metal layer 218 is respectively connected to the first contact hole 210a and the second contact hole 210b. One end of the scanning metal layer 112 and the second scanning metal layer 116 . ...

Description

technical field [0001] The present invention relates to a pixel structure and its manufacturing method, and in particular to a pixel structure capable of increasing aperture ratio and its manufacturing method. Background technique [0002] With the demand of the market, the size of the display panel is continuously increasing, and the data transmission frequency is increased in response to the high image quality, resulting in more obvious loss of signal transmission, resulting in uneven brightness of the picture (uniformity). In order to improve this problem, the cross-sectional area of ​​the signal line must be increased to reduce signal attenuation. Please refer to Figure 1A , which is a schematic diagram of a pixel structure of a conventional liquid crystal display device. The pixel structure 10 mainly includes a scan line 1 , a data line 2 , a thin film transistor 3 , a pixel electrode 4 and a storage capacitor 5 . The thin film transistor 3 is disposed on the scannin...
