Description

technical field [0001] The present invention relates to a display and its manufacturing method, in particular to an organic light emitting diode display and its manufacturing method. Background technique [0002] With the rapid advancement of display technology, semiconductor component technology, which is the core of the display device, has also been greatly improved. For existing display devices, Organic Light Emitting Diode (OLED) is a current-type light-emitting device, because of its characteristics of self-luminescence, fast response, wide viewing angle and the ability to be fabricated on flexible substrates. And it is increasingly being used in the field of high-performance display. In addition, OLED displays have many advantages such as bright colors, high contrast, low power consumption, and flexibility, and have become a hot spot for development and investment in the display field. With the maturity of the OLED display manufacturing process, OLED displays are mor...
