The embodiment of the present invention has the beneficial effect that: by being provided with three kinds of photochromic luminous subelements of difference at display base plate 10, base plate for packaging 13 is provided with the monochromatic color blocking 4 corresponding with the 3rd of display base plate 10 the luminous subelement 33, the short single color light emitting devices of working life is replaced with the 3rd luminous subelement 33, the monochromatic color blocking 4 utilizing the single color light emitting devices same color short with working life coordinates the 3rd luminous subelement, thus obtaining the monochromatic light of the single color light emitting devices same color short with working life, the working life of the OLED display panel that improve.
The embodiment of the present invention provides a kind of display device, including the display panels that provides of above-described embodiment or the OLED display panel that provides of above-described embodiment.
The embodiment of the present invention has the beneficial effect that: with the single color light emitting devices that the 3rd luminous subelement replacement working life is short, the monochromatic color blocking utilizing the single color light emitting devices same color short with working life coordinates the 3rd luminous subelement, thus obtaining the monochromatic light of the single color light emitting devices same color short with working life, the working life of the display floater that improve.
Obviously, the present invention can be carried out various change and modification without deviating from the spirit and scope of the present invention by those skilled in the art.So, if these amendments of the present invention and modification belong within the scope of the claims in the present invention and equivalent technologies thereof, then the present invention is also intended to comprise these change and modification.
