Embodiment Construction

[0031] figure 1 is a block diagram showing a gate driver 160 according to an exemplary embodiment of the present invention. refer to figure 1 , the gate driver 160 includes a circuit part CS and a line part LS adjacent to the circuit part CS.

[0032] This circuit part CS comprises first to last (1st to (n+1), denoted by subscripts) driver stages SRC connected in cascade to each other 1 to SRC n+1 , used to sequentially output the 1st to nth gate signal OUT 1 to OUT n , where 'n' is an even number.

[0033] The first to (n+1) driver stage SRC 1 to SRC n+1 Each of them includes: a first clock terminal CK1, a second clock terminal CK2, a first input terminal IN1, a second input terminal IN2, a cut-off (ground) voltage terminal V1, a reset terminal RE, a carry terminal CR and an output terminal OUT .

[0034] Apply the first clock signal CKV to the odd driver stage SRC 1 、SRC 3 ,...,SRC n+1 The first clock terminal CK1. The second clock signal CKVB having a different...

Abstract

In a driving unit (for example, a gate driving unit) and a flat panel display device having the driving unit, a circuit portion of the driving unit includes a plurality of driving stages cascaded with each other and outputs a (gate) driver based on a plurality of control signals. signals (multiple gate drive signals). The line part includes: a first signal line and a second signal line, where each signal line transmits a control signal from the outside; and a first connection line connecting the first signal line to the driver stage; and connecting the first signal line to the driver stage. The second signal line is connected to the second connection line of the driver stage. The second signal line is provided on a different (metallized) layer than the first signal line and the first and second connection lines. Therefore, failure of the drive unit due to corrosion can be prevented.

Description

technical field [0001] The present invention relates to a drive unit and a display device with the drive unit, in particular to a drive unit capable of preventing failure and a display device with the drive unit. Background technique [0002] Generally, a display device (for example, a liquid crystal display) includes: a display panel having a plurality of gate lines and a plurality of data lines; a gate driver disposed along one side of the display panel for The gate lines output gate driver signal(s); and a data driver placed on top of the display panel for outputting the data driver signal(s) to the data lines. [0003] A gate and data driver having a "built-in" structure is a chip mounted on a display panel substrate or an integrated circuit formed on the display panel substrate. When a display device has a built-in gate driver, the driver-related circuitry of the display device is advantageously reduced in size. [0004] The gate driver includes: a shift register comp...
