Abstract

The invention discloses an organic light-emitting device with an adjustable light-emitting color and a display device having the same. The organic light-emitting device with an adjustable light-emitting color includes, from bottom to top, a hole injection layer, a hole transport layer, a light emitting layer, an electron transport layer, an electron injection layer, and a cathode in this order. The light emitting layer includes a first light emitting layer, a second light emitting layer, and a buffer layer provided between the first light emitting layer and the second light emitting layer. The first light emitting layer is disposed adjacent to the hole transport layer. The second light emitting layer is disposed adjacent to the electron transport layer. The first light emitting layer andthe second light emitting layer are made of materials emiting light of different colors, respectively. According to the organic light-emitting device with an adjustable light-emitting color of the present invention, the organic light-emitting device can emit light of different colors under different driving voltages, reduces the amount of metal masks used, and achieves a high-resolution organic light-emitting device and an organic light-emitting diode display.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an organic light-emitting device with adjustable luminous color and a display device with the same. Background technique [0002] AMLCD (abbreviation for ActiveMatrixLiquid Crystal Display, liquid crystal display, its structure is to place a liquid crystal cell in two parallel glass substrates, set a TFT (thin film transistor) on the lower glass substrate, and set a color filter on the upper glass substrate, through the TFT The signals and voltages on the screen are changed to control the rotation direction of the liquid crystal molecules, so as to control whether the polarized light of each pixel point is emitted or not to achieve the display purpose). , is a solid thin-film light-emitting device formed by stacking organic light-emitting semiconductors. It belongs to a current-type organic light-emitting device that emits light through the injection and recombination of carrier...
