Embodiment 1
[0047] by image 3 The connection block 300 is partly located between the first drain 321 and the second drain 322 as an example, for clearer reference to the image 3 TFT and figure 1 Aperture ratios of TFT sub-pixel units are compared, such as Figure 5 shown, to include image 3 TFT and figure 1 The schematic diagram of the structure of the gate and the connection block (the black dotted line part), so that the aperture ratio between the two can be compared more clearly.
[0048] to combine figure 1 and image 3 ,Such as Figure 5 shown, assuming image 3 In the first subsection 311 and the third subsection 313 compared to figure 1 The lengthened distance is H, the second subsection 312 is compared to figure 1 The shortened distance is H, compared to figure 1 Medium TFT, image 3 The size of the reduced and increased parts of the middle channel width W is equal, that is, figure 1 and image 3 In comparison, the channel width W of the two is the same; then when ...
Embodiment 2
[0053] by Figure 4 The connection blocks 300 are all located between the first drain 321 and the second drain 321, and the upper edge of the connection block 300 is flush with the upper edges of the first drain 321 and the second drain 322, for a clearer alignment include Figure 4 TFT and figure 1 Aperture ratios of TFT sub-pixel units are compared, such as Figure 6 shown, to include Figure 4 TFT and figure 1 The schematic diagram of the gate and the connection block (the black dotted line part), so that the aperture ratio between the two can be compared more clearly.
[0054] to combine figure 1 and Figure 4 ,Such as Figure 6 As shown, in the case where the upper edge of the connection block 300 is flush with the upper edges of the first drain 321 and the second drain 322, without considering the lateral connection connecting the two sub-parts 301 in the connection block 300 in the prior art When the gap h between the sub-section 302 and the gate 10 (refer to f...
