Abstract

An embodiment of the present application provides a display panel, which is characterized in that the display panel comprises a first substrate and a plurality of light emitting units arranged on oneside of the first substrate, the light emitting units comprising light emitting diodes; a second substrate, and a plurality of driving circuits disposed on a side of the second substrate close to thelight emitting unit; each of the driving circuits being used for driving each of the light emitting units; and a light conversion layer including light conversion units of at least three colors, eachof the light conversion units being disposed in correspondence with each of the light emitting units. The present application can realize large-area transfer preparation of the display panel at one time, and has low alignment requirement and high yield.

Description

【Technical field】 [0001] The present invention relates to the field of display technology, in particular to a display panel and a display device. 【Background technique】 [0002] With the development of display technology, consumers have higher and higher requirements for the display effect of the display screen. One of the important indicators is the pixel density. A measure of pixel density is pixels per inch (PPI). However, the existing methods for preparing high-PPI display panels all have their own shortcomings. Micro-LED has extremely low production efficiency and poor yield due to problems such as mass transfer and alignment bonding. OLED is limited by the evaporation process, it is difficult to achieve high PPI, and the stability during organic light emission is poor, and the life of the display panel is short. The design of white light OLED + color film substrate has poor device stability, high power consumption and short life. At present, there is no product on...
