Abstract
Official abstract text for this publication.
An OLED display device is provided. The OLED display device includes a first transistor connected to a data line and a first node; a second transistor connected to the first node and a second node; a third transistor connected to a reference voltage terminal and a third node; a fourth transistor connected to an initialization voltage terminal and the second node; a fifth transistor connected to the reference voltage terminal and the second node; a driving transistor; and an OLED connected to a low-level power supply voltage terminal and the second node. The driving transistor has a source connected to the second node, a gate connected to the third node, and a drain connected to a high-level power supply voltage terminal.
First claim
Opening claim text (preview).
The invention claimed is: 1. An organic light emitting diode (OLED) display device, comprising: a first transistor directly connected to a data line and a first node, configured to transfer a data voltage from the data line to the first node; a second transistor directly connected to the first node and a second node, wherein the first node is directly connected to the first transistor; a third transistor directly connected to a reference voltage terminal and a third node, conf…
