More Information
Summary:The invention discloses an OLED (Organic Light Emitting Diode) phototherapy display screen. The display screen comprises a backboard driving circuit, a cathode layer, a packaging layer, a first sub-light-emitting unit, a second sub-light-emitting unit, a third sub-light-emitting unit, a fourth sub-light-emitting unit and a charge generation layer. The first light-emitting sub-unit, the second light-emitting sub-unit, the third light-emitting sub-unit and the fourth light-emitting sub-unit respectively emit light with peak wavelengths of 700-1400 nm, 600-700 nm, 500-600 nm and 400-500 nm; the first sub light-emitting unit is arranged on the backboard driving circuit; the second, third and fourth sub-light-emitting units are arranged in parallel and are arranged on the first sub-light-emitting unit; a charge generation layer is arranged between the first light-emitting sub-unit and the second, third and fourth light-emitting sub-units; the effective light-emitting area of the first light-emitting sub-unit compr
