According to an aspect of the present disclosure, there is provided a gate driver and a method of repairing the same. The gate driver can include a plurality of driving stages cascade connected, at least one repairing stage disposed between the plurality of driving stages, and a plurality of repair lines connected to the at least one repair stage. The plurality of repair lines overlap with a plurality of lines connected to the plurality of driving stages. The repairing stage can replace a defective driving stage of the gate driver.

Gate driver and method of repairing the same

A flexible display device and a method for manufacturing a flexible display device are provided. A flexible display device includes: a support substrate having a first thickness and including a first material, the support substrate further including first and second main faces opposite to each other, a buffer substrate on the first main face of the support substrate, the buffer substrate having a second thickness smaller than the first thickness, and the buffer substrate including a second material more flexible than the first material, a thin-film transistor array on the buffer substrate, such that the buffer substrate is between the thin-film transistor array and the support substrate, and a sealing substrate fixed above the thin-film transistor array, the thin-film transistor array being between the buffer substrate and the sealing substrate.

Flexible display device and method for manufacturing the device

An organic light emitting display includes a display panel, which includes a plurality of pixels and displays an image, and a data driving circuit differently outputting a compensation voltage depending on a sensing value based on a driving current. Each of the plurality of pixels includes an organic light emitting diode, a driving thin film transistor (TFT) having a double gate structure including a main gate electrode and a sub-gate electrode, a switching TFT applying a data voltage determining the driving current to the main gate electrode of the driving TFT, and a compensation TFT applying the compensation voltage for compensating for a shift amount of a threshold voltage of the driving TFT to the sub-gate electrode of the driving TFT.

Organic light emitting display

Discussed is an organic light-emitting display panel including: an active area corresponding to an image display region; and a non-active area corresponding to a region outside of the active area, wherein the active area includes a plurality of signal lines arranged in an array, wherein the non-active area includes a pad region to which a source driver IC is mounted, and a switching structure, wherein the pad region includes a plurality of pads arranged in correspondence with the array of the signal lines, and wherein the switching structure includes: a common reference voltage pad-connection terminal connected to a common reference voltage pad of the display panel; a plurality of reference voltage line-connection terminals connected to a plurality of reference voltage lines of the display panel; and a switching circuit to switch connections between the common reference voltage pad-connection terminal and the plurality of reference voltage line-connection terminals.
