Display substrate, display panel and display device

Abstract

The invention provides a display substrate, a display panel and a display device. The display substrate comprises a first substrate base plate and a filter layer, wherein the filter layer is arranged on the first substrate base plate, and comprises a red light unit, a green light unit and a blue light transmission unit; the red light unit comprises a red quantum dot material which is used for sending out red light under excitation of blue light; the green light unit comprises a green quantum dot material which is used for sending out green light under excitation of blue light; and the quantum dot material which is not covered by the blue light transmission unit is used for transmitting the blue light. According to the display substrate, the existing red light filter and green light filter are replaced with the quantum dot materials capable of generating red light or green light through blue light excitation; the existing blue light filter is removed; the quantum dot material which is not covered by the blue light transmission unit is used for transmitting the blue light, so that the utilization rate of a light source can be increased; meanwhile, colored light with relatively high purity is obtained; and high color range and low power consumption of color display are achieved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display substrate, a display panel and a display device. Background technique [0002] Please refer to figure 1 , figure 1 It is a structural schematic diagram of an existing WOLED (white light organic light emitting diode) display panel. The WOLED display panel includes: a first substrate 10 and a second substrate 20 oppositely arranged, and the first substrate 10 includes: a first base substrate 11 and a second substrate 20. The color filter layer 12 arranged on the base substrate, the color filter layer 12 includes a red filter R, a green filter G and a blue filter B, and the second substrate 20 includes: a second base substrate 21 and a white light emitting diode 22 disposed on the second base substrate 21 . [0003] In the course of actual research, it is found that the existing display mode that uses white light-emitting diodes to cooperate with common color f...
