Title:
表示パネルの駆動装置
Document Type and Number:
Japanese Patent JP5064696
Kind Code:
B2
Abstract:
A driver for a display panel in which a plurality of light-emitting elements are arranged in a matrix, prevents false emission and/or destruction of the light-emitting elements from being caused when reset control is performed when scanning row lines included in the display panel. A cathode driver includes a plurality of groups composed of a timing circuit and transistors that correspond to a plurality of cathode lines, respectively. Each of the timing circuits controls the timing for switching on the transistors, so that the potentials of all the cathode lines excluding the cathode line that is the target to be scanned are slowly changed from the ground potential to the power supply potential after the reset period elapses.
