Abstract

The invention provides a display, comprising a red light emitting unit, a green light emitting unit, and a blue light emitting unit, the red light emitting layer of the red light emitting unit is an organic metal halide perovskite material emitting red light, and the green light emitting unit The green light-emitting layer is an organic metal halide perovskite material that emits green light, and the blue light-emitting layer of the blue light-emitting unit is an organic blue light-emitting material other than the organic metal halide perovskite material, that is, the red light-emitting unit and the green light-emitting unit The light-emitting units all adopt the PeLED structure, and the blue-light emitting unit adopts the OLED structure. Except for the materials of the light-emitting layer, the materials of the red light-emitting unit, the green light-emitting unit, and the other structural layers of the blue light-emitting unit are the same, and can be produced in the same process. The preparation is completed, saving process time and production cost; because the price of the organic metal halide perovskite material of the red and green light-emitting layers is relatively low and the light color purity is high, the production cost of the display is further reduced and the color of the display is improved. saturation.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display. Background technique [0002] OLED (Organic Light-Emitting Diode, organic light-emitting diode) display, also known as organic electroluminescent display, due to its simple preparation process, low cost, low power consumption, high luminous brightness, wide range of operating temperature, light and thin volume, and fast response Fast, easy to realize color display and large-screen display, easy to realize matching with integrated circuit driver, easy to realize flexible display, so it has broad application prospects. [0003] According to the driving method, OLED can be divided into two categories: passive matrix OLED (Passive Matrix OLED, PMOLED) and active matrix OLED (Active Matrix OLED, AMOLED), namely direct addressing and thin film transistor matrix addressing. Among them, AMOLED has pixels arranged in an array, belongs to the active display type, has h...
