  • Patent number: 12210243
    Abstract: A quantum dot integrated board, a method for preparing a quantum dot integrated board, and a display apparatus including a quantum dot integrated board. The quantum dot integrated board includes a first optical transition layer, a first quantum dot layer, a second optical transition layer, and a second quantum dot layer, which are sequentially arranged. The refractive indexes of the layers meet: tfirst optical transition layer<tfirst quantum dot layer, tsecond optical transition layer<tfirst quantum dot layer, tsecond optical transition layer<tsecond quantum dot layer; and the first quantum dot layer includes a red quantum dot material, and the second quantum dot layer includes a green quantum dot material. Therefore, a brightness enhancement structure is better used, the utilization rate of light is increased, and the output of blue light is reduced while the brightness value of a quantum dot board material is increased.
