Display panel with phosphorescent and fluorescent pixels

Abstract

A display panel comprises a plurality of arranged pixels of organic EL devices, each having a pair of electrodes and a luminescent layer containing an organic EL material and sandwiched between the electrodes. The plurality of arranged pixels include fluorescent pixels of organic EL devices formed by mainly using a fluorescent material and phosphorescent pixels of organic EL devices formed by mainly using a phosphorescent material. A display apparatus comprises a controller for controlling the display panel, including correcting the difference between the electroluminescent characteristics of the fluorescent pixels and those of the phosphorescent pixels.

What is claimed is: 
     
       1. A display apparatus comprising:
 (a) a display panel comprising a plurality of pixels of organic electroluminescent devices and a plurality of data lines for supplying video signals to each of the plurality of pixels, the plurality of pixels including fluorescent pixels and phosphorescent pixels which are arranged along the plurality of data lines, each of the plurality of pixels including:
 an organic electroluminescent device, 
 a first transistor which supplies a current to the organic electroluminescent device, 
 a second transistor which is electrically connected to a gate electrode of the first transistor and electrically connected to one of the data lines, and 
 a hold capacitance which is electrically connected to the gate electrode of the first transistor for holding a voltage corresponding to a supplied video signal; and 
 
 (b) a controller display control section which corrects the video signals and supplies the corrected video signals to the plurality of pixels through the data lines, a signal supplied to the fluorescent pixels being different from a signal supplied to the phosphorescent pixels such that a difference of efficiency of electroluminescence between the fluorescent pixels and the phosphorescent pixels is compensated. 
 
     
     
       2. A display apparatus comprising:
 (a) a display panel comprising a plurality of pixels of organic electroluminescent devices, the plurality of pixels including fluorescent pixels and phosphorescent pixels; and 
 (b) a controller display control section which supplies signals to the plurality of pixels, a signal supplied to the fluorescent pixels being different from a signal supplied to the phosphorescent pixels, 
 wherein a timing of falling edge of the signal supplied to the phosphorescent pixels being is earlier than that of the signal supplied to the fluorescent pixels. 
 
     
     
       3. The display apparatus according to claim 1, wherein the data signals are supplied from the display control section to the plurality of pixels via a latch.
