BOE announced that with “R & D and industrialization of high-resolution flexible flexible flexible AMOLED display technology for mobile applications”, it won the grand prize of Beijing Science and Technology Progress Award in 2019. BOE said that the folding screen mobile phone is a representative application of flexible AMOLED technology, but at present, there are only a few manufacturers in the world that can actually mass produce folding mobile phones. One of the key points is that folding display screen, as an important core device, has high requirements for bending resistance, high-resolution design and process integration. < / P > < p > this time, BOE has broken through the limitation that only thinner integrated structure can realize small radius folding. It has designed multi-layer structure of AMOLED products with external folding, and has realized 200000 times of bending under the condition of curvature radius of 5mm. < / P > < p > it is also introduced that in the field of flexible display, BOE adopts a new type of ggrb sub-pixel layout with independent intellectual property rights. The number of green sub-pixels is twice that of red and blue sub-pixels. The arrangement can achieve a larger proportion of luminous materials in sub-pixels with the same spacing, which can effectively avoid the problem of screen burning.
