Description
technical field [0001] The invention relates to the field of manufacturing curved displays, in particular to a method for manufacturing a curved organic light emitting diode display device and a panel. Background technique [0002] Conventional curved OLED display panels are generally formed by bending a flat OLED display panel. [0003] During the bending process of a flat OLED display panel, devices in the OLED display panel are stretched or squeezed. [0004] The structural strength of the curved organic light emitting diode display panel will be reduced due to the bending operation. At this time, the devices in the curved organic light emitting diode display panel are prone to bursting, and even the curved organic light emitting diode display panel cannot normal display. Contents of the invention [0005] The object of the present invention is to provide a curved organic light emitting diode display device and a method for manufacturing a panel, which can improve the...
