Organic light-emitting diode (oled) display panel, electronic device and manufacturing method

A manufacturing method for the OLED display panel, comprising:

• sequentially forming a first electrode, a light-emitting layer, a first function layer, and a second electrode, the light-emitting layer including a host material of the light-emitting layer and a guest material of the light-emitting layer;
• or
• sequentially forming a second electrode, a first function layer, a light-emitting layer, and a first electrode, wherein:
• the first function layer includes at least a first-type blocking layer disposed adjacent to the light-emitting layer, a first guest material is doped into a host material of the first function layer, and a ratio of a second-type carrier mobility of the host material over a second-type carrier mobility of the first guest material is greater than or equal to about 10;
• the first-type is a hole-type and the second-type is an electron-type, and
• TB>TC and TA>TC, such that triplet state excitons of the light-emitting layer is prevented from being transmitted through the first-type blocking layer, where TB is a triplet state energy level of a host material of the first-type blocking layer, TC is a triplet state energy level of a host material of the light-emitting layer, TA is a triplet state energy level of a first guest material of the first-type blocking layer.
