Problems solved by technology

However, the wiring method in the prior art often forms a large free space above the floating channel at the outlet end of the IC, which in turn increases the wiring space, and the resistance difference between the various lines is relatively large, which easily leads to a split screen phenomenon.

Embodiment Construction

[0025] In the following detailed description, reference is made to the accompanying drawings, which form a part hereof, and which show by way of illustration specific embodiments in which the invention may be practiced.

[0026] figure 1 The arrangement of fan-out lines for connecting IC terminal 1 and display terminal 2 in the prior art is shown. Such as figure 1 As shown in FIG. 1 , the channel in the middle section of the outlet end at IC terminal 1 is left unused, thereby forming a dummy section. Taking the wiring requirement of 15.6FHD as an example, the number of channels of IC terminal 1 is 1200, but the number of channels actually used is 960. Therefore, the 240 channels in the center of the IC are actually unused, forming a floating section above these channels.

[0027] In view of the above situation, the traditional wiring method is the wiring form of the channel 11 at the outermost end of the IC (the basic line type of the channel has two sections, that is, sect...

Abstract

The invention relates to a fan-out line structure, a display apparatus comprising the same, and a fan-out line wiring method. The fan-out line structure provided by the embodiments of the invention is used for signal connection between a first function area and a second function area, an intermediate-section channel at a channel wire outlet end of the first function area is a suspended channel, in the fan-out line structure, a wire from an effective signal channel closes to the suspended channel, of the first function area to the second function area extends to a center normal area of the suspended channel and then extends in the center normal area along the direction of a center normal. The fan-out line structure can reduce wiring space and reduces signal delay differences between wires.

Description

technical field [0001] The present invention relates to the field of display technology, and in particular to a fan-out line structure, a display device including the fan-out line structure, a display device including the same, and a fan-out line wiring method. Background technique [0002] Fan-out routing is an important part of circuit board design, especially TFT-LCD panel design. However, the difference in resistance between each line in the fan-out line will cause inconsistency in signal delay, which can easily cause split-screen phenomena or vertical and horizontal blocks in TFT-LCD panels. And when the number of channels at the IC end is not equal to the number of channels in the display area, that is, when the number of channels in the display area is less than the number of channels of the IC used, in order to make the wiring space in the horizontal direction more sufficient, the channels on both sides of the IC are often used, that is, the middle The extra channel...
