Display device

摘要

A display device includes a plurality of common lines, a plurality of driving lines, a plurality of light emitting elements, a source driver, a sink driver, discharge devices, discharge limiting devices, and rectifying devices. The discharge devices are connected to the common lines and configured to lower voltage at the connected common lines. The discharge limiting devices are connected to the common lines and to the discharge devices, and apply a limitation so that the voltage at the connected common lines is not lowered below a prescribed value by the discharge devices. The rectifying devices are connected between the discharge devices and the discharge limiting devices, and the common lines, and pass a current from the common lines toward the discharge devices and the discharge limiting devices but do not pass a current from the discharge devices and the discharge limiting devices toward the common lines.

1. A display device comprising:
a plurality of common lines; a plurality of driving lines; a plurality of light emitting elements connected to the plurality of common lines and the plurality of driving lines; a source driver configured to apply voltage by time division to the plurality of common lines; a sink driver configured to draw a current from one or more driving lines among the plurality of driving lines to turn on one or more light emitting elements; at least one discharge device connected to the common lines, the at least one discharge device being configured to lower voltage at a respective common line when voltage is not applied to the respective common line by the source driver; at least one discharge limiting device connected to the common lines and to the at least one discharge device, the at least one discharge limiting device being configured to apply a limitation so that the voltage at the respective common line is not lowered below a prescribed value by the at least one discharge device when voltage is not applied to the respective common line by the source driver; and rectifying devices connected between the at least one discharge device and the at least one discharge limiting device, and the common lines, and which pass a current from the common lines toward the at least one discharge device and the at least one discharge limiting device but do not pass a current from the at least one discharge device and the at least one discharge limiting device toward the common lines.
