Abstract: An all-plastic self-locking pump includes a pump body extending into a bottle, provided with a pump chamber and connected with a bottle locking cover, a suction assembly is arranged in the pump chamber, a check valve is arranged at a lower end of the pump chamber. A button is connected to an upper end of the suction assembly, a self-locking cover is arranged on the pump chamber, a plastic annular part is arranged in the pump chamber above the check valve, and an opening is formed in a side face of the plastic annular part. A locking mechanism is arranged between the button and the self-locking cover, and after the button is rotated to an unlocking position from a locking position, the button can be pressed to enable liquid in the bottle to be sprayed out of an outlet of the button.

Abstract: A display panel includes a plurality of pixel units arranged in an array and a plurality of data lines. The pixel units in two adjacent rows in two adjacent columns form a grayscale combined pixel. The grayscale combined pixel comprises three sub-pixels corresponding to the high grayscale and nine sub-pixels corresponding to the low grayscale.

Abstract: A display panel and a display device are disclosed. The display panel includes a substrate, a plurality of data line groups located on the substrate and adjacently arranged in order, a plurality of gate line groups located on the substrate and adjacently arranged in order, and a plurality of pixel electrode array units. The pixel electrode array units include a first pixel electrode, a second pixel electrode, and a third pixel electrode. The display panel improves arrangement of the pixel electrode array units, which effectively reduces graininess on a display screen and improves viewing angles of the display screen.
