    Abstract: The present disclosure provides an emission driving circuit, which includes: a first node control module configured to provide an input signal or a high level signal to a first node based on a first clock signal and a second clock signal, to control a level at the first node; a second node control module configured to control a level at a second node based on the level at the first node, the first clock signal, the second clock signal, a first low level signal and the high level signal; and an output control module configured to control an output terminal to output high or low level based on level at the first node, level at the second node, the high level signal and a second low level signal. A low level of the first low level signal is different from a low level of the second low level signal.

    Abstract: A display panel has a display area and a non-display area surrounding the display area. The display area has a first side and a second side opposite to the first side, and includes: a hollow area having first and second edges; and first to third display areas. The display panel includes: a driving chip arranged in the non-display area closer to the first side than to the second side; first data lines arranged in the first display area; second data lines arranged in the second display area; and third data lines arranged in the third display area. The first edge is closer to the driving chip than the second edge. At least one or more of the first data lines is connected to corresponding one or more of the second data lines through a switch unit.

    Abstract: The present disclosure provides a shift register. The shift register includes: a first node control module for controlling level at the first node; a second node control module for controlling level at a second node; and an output control module for controlling the output terminal to output high or low level. The first node control module includes an input unit configured to write the input signal into the third node and a protection unit configured to control a level at a fourth node based on a level at the third node and control writing of the level at the fourth node into the first node based on the second clock signal. The technical solution of the present disclosure can prevent the transistor for providing the third node with inputting signal from being broken down.

    Abstract: The present disclosure provides an aromatic heterocyclic compound having property of thermally activated delayed fluorescence (TADF). The aromatic heterocyclic compound has a structure represented by Formula (I), in which X1 and X2 each is S, O, Se, or C; D is an electron donor, A is an electron acceptor; m is a number of the electron donor D, and the m electron donors D are the same or different; n is a number of the electron acceptor, and the n electron acceptors are the same or different; and m and n are 1 or 2. The aromatic heterocyclic compound provides a high luminescence efficiency. Organic light-emitting display devices including such aromatic heterocyclic compound have improved luminescence efficiency, lower cost and longer service life by using the aromatic heterocyclic compound as a light-emitting material, a host material, or a guest material.
