  • Patent number: 10580374
    Abstract: A co-gate electrode between pixels structure includes a first pixel and a second pixel. The first pixel has a first control switch is electrically connected to a main control switch. The main control switch selectively receives an external voltage and then transmits the external voltage to the first control switch. The first control switch selectively receives the external voltage, lest the external voltage transmitted to the first pixel to charge or discharge establish a voltage drop. The second pixel has a second control switch, which is electrically connected to the main control switch to selectively receive the external voltage transmitted by the main control switch, lest the external voltage that is transmitted to the second pixel to charge or discharge establish a voltage drop. The present invention is used for a panel with pixels of small area and high resolution.

  • Patent number: 9064474
    Abstract: An n-stage driving module with a common control node according to the present invention is revealed. The n-stage driving module comprises a plurality of output units, a forward input unit and a reverse input unit. The output units are all coupled to a control node to share the control node. The output units output forward scanning signals sequentially according to the charge of the control node when the control node is charged by the forward input unit. The output units output reverse scanning signals sequentially according to the charge of the control node when the control node is charged by the reverse input unit. Thus, the present invention is provided to output forward or reverse scanning signals from the output units by sharing the control node so as to decrease the circuit area in the n-stage driving module.

    Abstract: The invention provides a bidirectional scanning driving circuit, which comprises N stages of driving modules. Driving module comprises an output unit, a forward input unit, and a reverse input unit. For the n-th stage driving module, the forward input unit receives a first input voltage and a front forward scan signal of any of the driving modules lower than or equal to (n?2)th stage for charging or discharging a control node of the output unit. The reverse input unit receives a second input voltage and a back reverse scan signal of any of the driving modules higher than or equal to (n+2)th stage for charging or discharging the control node of the output unit. When the forward input unit is charging the output unit, the output unit outputs a forward scan signal; when the reverse input unit is charging the output unit, the output unit outputs a reverse scan signal.
