Abstract
The present invention provides an OLED color display device, comprising a substrate (), an anode (), a thin film transistor array (), a Hole Injection Layer (), a Hole Transport Layer (), a light emitting layer (), an Electron Transport Layer (), a cathode (), a package cover plate (), a color conversion layer () and a seal frame (); the light emitting layer () comprises a first light emitting layer () and the second light emitting layer (), and both the first light emitting layer () and the second light emitting layer () are manufactured by host material doped with guest material, and the guest material comprises luminescent material and electron transport material; the first light emitting layer () is a blue light emitting layer, and the second light emitting layer () is a red, green lights commonly emitting layer, a yellow light emitting layer or a green light emitting layer; lights emitted by the first light emitting layer () and the second light emitting layer () synthesize white light or blue, green light possessing higher energy efficiency and luminescence efficiency. The power consumption is low.
