Abstract: An LED display screen and a manufacturing method therefor. The method comprises: presetting a temporary jig consisting of a first substrate (1) having a plurality of placement grooves, and a cover plate (3), and alternately placing R, G, and B-color LEDs in the placement grooves (2) by means of placement groove inlets (4); attaching a side cover to the temporary jig, and replacing the cover plate with an LED substrate and attaching the LEDs to the LED substrate; removing the first substrate and the side cover and sealing the LED substrate, and connecting a circuit board to the LED substrate, so as to obtain the LED display screen.

Abstract: Disclosed is a television color cast adjustment method, including: dividing a television display screen into a plurality of areas according to a predetermined manner; determining an adjustment coefficient of red light and an adjustment coefficient of blue light in each area according to a position of each area relative to a light bar for the television display screen; adjusting initial image in each area according to the adjustment coefficients of red light and blue light thereof, and displaying the adjusted image in each area on the television display screen. Disclosed is also a television color cast adjustment apparatus. The present disclosure may solve the problem that the color cast appears on television display screens which is caused by the glass light guide plate, thus the viewing effect of TVs is improved.
