Embodiment Construction

[0054] Such as Figure 5 As shown, the driving circuit 32 of the liquid crystal display panel according to the present invention includes a thin film transistor substrate 33, two driver IC chips 34 and 36 arranged on the thin film transistor substrate 33, a current supply source 42, and a wire group 40, for To connect the driver IC chips 34 and 36 to the current supply source 42 in parallel.

[0055] The wire group 40 is composed of a plurality of wire segments, and the shape of each wire segment is not particularly limited, as long as it can be arranged on the substrate and meets the required resistance value, so that each parallel driver IC chip can obtain approximately the same voltage input value. . Such as Figure 5 As shown, the wire set 40 is composed of a main wire 38 and two branch wires 39a and 39b. One end of the main line 38 is connected to the current supply source 42 , and the branch lines 39 a and 39 b respectively connect the other end of the main line 38 to...

Abstract

The LCD panel drive circuit includes a substrate with multiple driver IC chips, a current supply power, and a first wire group to paralleled connect the IC chips with power with same resistance value and then same input voltage. This invention can avoid uneven block color in the figure.

Description

technical field [0001] The present invention relates to a driving circuit of a liquid crystal display panel, in particular to a driving circuit that enables each driver IC chip (driver IC chip for short) to obtain a same input voltage. Background technique [0002] TFT-LCD panels mainly use matrix-arranged TFTs to drive liquid crystal pixels with appropriate capacitors, transfer pads and other electronic components to produce rich and bright graphics. Generally speaking, a thin film transistor liquid crystal display panel includes an upper substrate with a color filter, a lower substrate, and a liquid crystal material filled between the upper substrate and the lower substrate. There are a plurality of scan or gate lines and signal lines (data or signal lines) perpendicular to each other on the lower substrate, and at least one thin film transistor is arranged at the intersection of each of the scan lines and each of the signal lines, It is used as a switch device for a pixe...
