The invention discloses a method of controlling display of a display screen. The method includes: setting a first arc assisting line and a second arc assisting line at a position close to the edge ofthe display screen, wherein the first arc assisting line and the second arc assisting line are arranged at an interval and divide the display screen into a complete display area, a non-display area and a transitional display area, and multiple transitional pixel units are included in the transitional display screen; setting pixel aperture ratio of the transitional pixel units in the transitional display area to be greater than 0 and smaller than that of the pixel units in the complete display area. By setting brightness of the pixel units of the transitional display area to be gradually improved through the method, sawtooth feeling at the edge of the screen can be well smoothened and improved, so that visual effect is optimized. The invention further provides the display screen set by themethod and a terminal comprising the display screen.
