Abstract

The invention discloses a display panel and a display device. Through the setting of the signal bus, signals can be respectively provided for the first signal line in the first display area and the second signal line in the second display area, so as to ensure the first display area and the second display area can normally display images; and, by increasing the width of the signal bus, the voltage drop can be reduced when transmitting signals, so as to reduce the voltage transmitted to the first signal line and the second signal line as much as possible. Signal difference, thereby reducing the display difference between the first display area and the second display area, thereby improving the uniformity of the display picture.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] Organic Light Emitting Diode (OLED) display is a self-luminous display, and has the characteristics of thinness, high chromaticity, wide viewing angle and fast response speed, and has great development prospects in the field of display technology. With the development of technology, OLED displays are gradually developing in the direction of narrow borders, high screen-to-body ratio and thinner to meet the needs of users. However, as the frame becomes narrower and the screen-to-body ratio gradually increases, the number of pixel units in the display area increases significantly. Correspondingly, the length of signal lines for transmitting signals also increases significantly, resulting in signal The voltage drop of the line increases significantly, which causes the display uniformity of the entire display panel ...
