Title:
DISPLAY DEVICE DRIVING CIRCUIT AND DISPLAY DEVICE
Document Type and Number:
Japanese Patent JP2016118663
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a gate line partial driving circuit technology enabling a stable operation by making voltage application stress uniform during partial driving.SOLUTION: The display device driving circuit includes a plurality of stages of shift registers (10), and a plurality of stages of gate driver parts (30), can perform partial driving of a plurality of gate lines, and further includes a plurality of stages of Q node driver parts (40). In each of the plurality of stages of Q node drivers, when it is determined that the gage driver part is not activated in partial driving because the output of the shift register is in an "H" state and the QD mode of the gate driver part is in an "L" state at a given stage, a clock activated during a period not affecting the displaying of the given stage is used, and the gate driver determined not to have been activated is activated during a period not affecting the displaying.SELECTED DRAWING: Figure 5
