Abstract: An organic light-emitting device includes an anode electrode and a cathode electrode that are arranged facing each other; a light-emitting layer arranged between the anode electrode and the cathode electrode; and a hole transport layer arranged between the anode electrode and the light-emitting layer, contacting the light-emitting layer. The light-emitting layer includes a first host material and a second host material. An energy difference ΔE1 between a HOMO energy level of the first host material and a HOMO energy level 13H of the hole transport layer 14aH is less than an energy difference ΔE2 between a HOMO energy level 14bH of the second host material and the HOMO energy level 13H of the hole transport layer. The difference between the HOMO energy level 13H of the hole transport layer and the HOMO energy level 14aH of the first host material is 0.37 eV or less.

Abstract: Disclosed is a method of controlling a backlight for of a display panel. The backlight includes backlight blocks. The display panel includes display region blocks opposite to the backlight blocks in one-to-one correspondence. The method determines, for each of the backlight blocks, a luminance value demanded from each of pixels in display region blocks including a display region block opposite to the backlight block and one or more display region blocks adjacent to the opposite display region block to the backlight block based on a luminance value of the pixel and a weight determined depending on a relation of a location of the pixel and a location of the backlight block. The method determines, for each of the backlight blocks, a highest value among the demanded luminance values for the backlight block to be a luminance value for the backlight block.
