A touch panel and a peripheral circuit thereof are provided. Each bonding pad of the peripheral circuit includes a first conductive layer, a first protective layer, a second conductive layer, and a second protective layer sequentially arranged on a substrate from bottom to top. A covered area of the second conductive layer provided by the second protective layer is increased to cover a portion of the second conductive layer located above a junction area between the first protective layer and a terminal part of the first conductive layer, thereby increasing the reliability of the bonding pads.

Touch panel and peripheral circuit thereof

The present invention discloses an OLED driving device, including a first switch transistor, a first transistor, a second switch transistor, a storage capacitor and a second transistor. The first switch transistor is used to receive a data signal, and output the data signal by the control of a first scan signal. The first transistor is used to compensate the effect of the threshold voltage of the second transistor. The second switch transistor is used to receive a voltage signal, and output the voltage signal by the control of a second scan signal. The storage capacitor is used to store a data voltage. The second transistor is electrically connected to the second switch transistor through the storage capacitor. The present invention can efficiently release the charges from the storage capacitor, enhance display effect, and change the input voltage level for adapting different operating voltages of integrate circuits.

Organic light emitting diode driving device

A shift register apparatus and a method thereof are provided. The technique manner submitted by the present invention utilizes two NMOS transistors for pulling down the voltage level of the scan signals output by the shift registers within the shift register apparatus to the low level gate voltage, wherein one of the NMOS transistors is controlled by a control unit, and the other NMOS transistor is controlled by a clock signal or the inverted clock signal provided to the shift registers. Therefore, shifting amount of the threshold voltage of those NMOS transistors can trend to be flat, and the reliability of those NMOS transistors can be promoted. In addition, since only one control unit is needed to dispose in each shift register so that the layout area of whole shift register apparatus can be reduced, and the panel with narrow frame size also can be achieved by the present invention.

Shift register apparatus and method thereof

A shift register, a driving circuit and a display device using the same are disclosed. The shift register includes a 1and a 2rectifying elements and 1&#x2dc;4transistors. 1source/drains of the 1&#x2dc;3transistors receive a common voltage respectively. The gates of the 1and 3transistors and a 2source/drain of the 2transistor are coupled to a 2terminal of the 2rectifying element. The gates of the 2and 4transistors and a 2source/drain of the 1transistor are coupled to a 2terminal of the 1rectifying element. A 1source/drain of the 4transistor is coupled to a 2source/drain of the 3transistor. The 1terminals of the 1and 2rectifying elements respectively receive input signals and a 1clock signal. A 2source/drain of the 4transistor receives a 2clock signal.
