An optimization design of irradiance array is proposed for the direct‐lit LED backlight. A rectangular irradiance distribution is generated by each LED lens unit, and the desired backlight is obtained by arraying the irradiance distribution. Compared with the traditional methods, the efficiency is significantly enhanced and the number of the units is dramatically reduced.
