Embodiments of the present disclosure relate to a transparent touch display device, and more particularly, to a transparent display device including a touch electrode having a low reflection structure. The touch electrode having the low reflection structure may include a mesh type sensor metal formed a plurality of openings, a sensor transmission layer on the sensor metal, and a sensor auxiliary metal on the sensor transmission layer. Part of the incident light incident on the upper surface of the sensor auxiliary metal is reflected from the upper surface of the sensor auxiliary metal, and another part of the incident light incident on the upper surface of the sensor auxiliary metal is reflected from the upper surface of the sensor metal after passing through the sensor auxiliary metal and the sensor transmission layer.

Transparent touch display device

An organic light emitting display device and a fabrication method comprising a touch electrode layer including touch electrodes and touch lines on an upper substrate which are directly formed on the upper substrate to secure a large distance between the touch electrodes and cathode as well as minimize a distance between the upper and lower substrates, thereby widening the viewing angle of an image while reducing a parasitic capacitance.

Organic light emitting display device and fabricating method using the same

A display device is set forth that comprises a display panel having a plurality of pixels arranged in a matrix. A data driver supplies pixel drive signals to data lines that are connected to drive the individual pixels of at least one row of pixels with corresponding pixel drive signals. The display device also includes a gate driver that supplies gate drive signals to the gate lines of the matrix. Each gate line may be connected to concurrently drive at least one row of pixels with a respective gate drive signal. The gate driver may comprise a sequence of shift registers that are connected in cascade with one another and two or more phase clocks that are connected to drive the sequence of shift registers. The shift registers of the gate driver may be interconnected with one another so that a shift register to which a given phase clock is applied is reset using an output signal from a next occurring shift register in the sequence of shift registers that is also connected to the given phase clock.

Gate driver having a plurality of shift registers, driving method thereof and display device having the same

A gate driver includes a plurality of shift registers connected in cascade to each other and driven by a plurality of multiphase clocks, respectively, wherein the next shift register to which one of the plurality of multiphase clocks is applied is reset using an output signal outputted from the previous shift register in response to the one of the plurality of multiphase clocks.
