Abstract: A display device provided includes a display panel, a first backlight module, a second backlight module, a light sensor, and a viewing angle adjusting component. The first backlight module includes an optical element, and the viewing angle adjusting component is disposed corresponding to a display sensing area. When the optical element is in a fog state, the viewing angle adjusting component reduces an exit angle of backlight. When the optical element is in a transparent state, external light enters the light sensor through the viewing angle adjusting component and the first backlight module, which improves uniformity of backlight viewing angle.

Abstract: A display panel and a display device are provided. The display panel and display device include gate driver on array (GOA) units in a first column, GOA units in a second column, and signal input lines. By adjusting a positional relationship between the signal input line and the GOA units in the first column and the GOA unit in the second column, the GOA units in the first column and the GOA units in the second column may share the signal input line, so as to save a set of signal input lines and reduce a width of the frame area.
