Looking ahead to 2019, WitsView expects a high possibility of the mass production of products with Mini LED backlighting. The processing costs of display units may increase by 20% to 100% depending on the number of Mini LED used.
According to Julian Lee, the Assistant Research Manager of WitsView, the number of Mini LED used in a display unit is decided by the thickness of the display and the luminance of the backlight unit. On one hand, the optical distance in the backlight unit is bound to be reduced to meet the market demand for thinner consumer electronic devices.
On the other hand, the number of Mini LED needed for a single product remains high in order to maintain the high standard of optical performance. With decreasing the number of Mini LED used to be a possible way of cost reduction while keeping the products thinner, the manufactures may turn to increase beam angle as a solution. Current beam angle of Mini LED is around 120 to 140 degrees, and the epitaxy manufactures have been working on increasing the angle to 140 to 160 degrees.
