摘要： An organic electroluminescence display panel, a manufacturing method, a color shift reducing method, and a display device are provided. The display panel includes a flat surface portion and a curved surface portion. The hole transport layer of the display panel includes a common hole transport layer and hole transport units. The common hole transport layer is distributed in the flat surface portion and the curved surface portion. The hole transport units are disposed on the common hole transport layer and are in one-to-one relationship with sub-pixels of the two portions; the hole transport layer of the sub-pixel of at least one color has different thickness in the two portions; and the thickness of the hole transport layer of the sub-pixel is the sum of the thickness of the common hole transport layer in sub-pixel and the thickness of the hole transport unit of the sub-pixel.

摘要： The present disclosure relates to a display substrate, a display device, and a control method thereof. The display substrate includes a plurality of pixels, each of which includes a first sub-pixel, a second sub-pixel, a third sub-pixel, and a fourth sub-pixel. The first sub-pixel, the second sub-pixel, and the third sub-pixel have different light emission colors. The fourth sub-pixel has the same light emission color as the first sub-pixel. The first sub-pixel, the second sub-pixel, the third sub-pixel, and the fourth sub-pixel all emit light, in a case where an ambient temperature is less than a first threshold. The second sub-pixel and the third sub-pixel both emit light, and one of the fourth sub-pixel and the first sub-pixel emits light, in a case where the ambient temperature is greater than or equal to the first threshold.
