Abstract

The invention relates to a display device comprising a backlight source, a control back panel, a display layer, a quantum dot color film and a photosensor array. Since the quantum dot film layer unitcan generate light with different wavelengths under excitation to correspond to colors of different pixel units, the control of the color effect s realized and the utilization rate of the light sourceis increased. Besides, the quantum dot film layer unit includes a nanoporous frame and the quantum dots arranged at the nanoporous frame; the arrangement of the quantum dots and the sizes of the quantum dots can be adjusted and controlled in an order by the nanoporous frame, so that the quantum dots are arranged uniformly and stably in order; and thus the arrangement of the luminescence spectrumand colors as well as the color uniformity can be regulated and the color gamut can be widened, so that the good color display effect is realized. Therefore, on the basis of combination of the photosensor array and the quantum dot film layer, the sensing images with the high quality and rich colors can be obtained and the user experience can be improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display device. Background technique [0002] With the continuous development of display technology, people have higher and higher requirements for display quality and color effects of display devices. Display devices usually utilize color filters to achieve full-color effects. An exemplary color filter is generally composed of a glass substrate, a black matrix, and a color layer. Usually, an LED (Light Emitting Diode, white light emitting diode) backlight source is used to cooperate with the color filter to form a color display. However, this color display mode has a low light source utilization rate, and the display has a narrow color gamut. [0003] Therefore, the exemplary color filter has the problems of low light source utilization and narrow color gamut of the display. Contents of the invention [0004] Based on this, it is necessary to provide a display de...
