Abstract— In the past years, the thermal management of the LEDs in an LCD TV with an LED backlight has evolved to cater to steadily increasing power densities in ever thinner product enclosures. In the lighting and computer industry, solutions to comparable thermal challenges are based on the use of large‐finned heat sinks. In the thin form factor of a modern TV set, this is not feasible, and the only large surface areas available for cooling are located on the front and the back of the TV set. The role of the in‐plane spreading has not been addressed thus far. The scope of the present work is to clarify the thermal significance of heat spreading in the in‐plane direction in the set, especially in relation to cost down through the use of less LED packages at equal total light output.
