Problems solved by technology

However, the charge generation layer has a strong electrical conductivity, which will cause the charges in the charge generation layer to be transmitted laterally, and the aging of the organic material in the pixel region will further lead to the lateral transfer of charges. Therefore, when the display panel displays a monochrome picture (ie When a solid-color picture, such as a red picture, a green picture or a blue picture), the charge transmitted laterally to the adjacent OLED will cause the adjacent OLED pixel to light up, resulting in poor crosstalk, making the monochrome display unsaturated, reducing the color gamut, etc., affecting The display performance of the OLED display panel

Abstract

The invention discloses a display panel, a preparation method thereof, a driving control method, and a display device. The display panel includes a driving substrate, a first electrode arranged on the driving substrate and located in the pixel area, and a pixel defining layer arranged on the first electrode and defining the pixel area, and the display panel also includes an electrode arranged on the pixel area. The light emitting structure layer on the pixel defining layer, the second electrode disposed on the light emitting structure layer, and the magnetic field disposed in at least one of the pixel regions, the direction of the magnetic field forms a certain angle with the plane where the driving substrate is located . In the display panel, when the charges in the light-emitting structure layer are transported laterally, the magnetic field will generate a Lorentz force on the charges, changing the direction of movement of the charges, causing the charges to perform a spiral motion, greatly increasing the travel of the charges, and limiting the lateral transfer of the charges. , reducing the brightness of adjacent pixels, avoiding bad crosstalk, and improving the display quality of the display panel.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display panel, a manufacturing method thereof, a driving control method, and a display device. Background technique [0002] The organic light emitting diode display panel (Organic Light Emitting Diode, OLED) has the characteristics of all solid state, self-illumination, high contrast ratio, wide viewing angle, etc., and is a next-generation flat panel display panel after the liquid crystal display panel. [0003] Large-size OLED display panels generally use a combination of white OLED and color film to generate red, green and blue light. White light OLEDs usually use stacked 2-layer or 3-layer sub-light-emitting layers to generate white light, and charge generation layers (CGL) are used to connect adjacent sub-light-emitting layers to reduce the voltage of white light OLED devices. The charge generation layer needs to be made of a material with strong conductivity. At presen...
