Four-side curved screen and spraying process thereof

The invention belongs to the field of electronic equipment, and particularly discloses a four-side curved screen and a spraying process thereof. The four-side curved screen comprises a four-side curved plate, the four-side curved plate comprises a straight panel and a peripheral panel, and the peripheral panel is arranged at the edge of the straight panel; first photoresist layers are arranged atfour corners of the bottom surface of the straight panel; and second photoresist layers are arranged at the four corners of the outer surface of the peripheral panel, and the first photoresist layersare connected with the second photoresist layers. According to the spraying exposure process, the glass panel of the display area is evenly coated with the photoresist through the high-precision spraygun of a rotary angle spraying machine, plasma cleaning is adopted, the adhesion firmness degree between the photoresist and the glass panel is increased, then the exposure machine is used for exposure, and patterns are formed
