AB  - We use a mixed host, 2,6-bis[3-(carbazol-9-yl)phenyl]pyridine blended with 20 wt 
      % tris(4-carbazoyl-9-ylphenyl)amine, to lower the hole-injection barrier, along 
      with the bipolar and high-photoluminescence-quantum-yield (Phi(p)= 84%), blue 
      thermally activated delay fluorescence (TADF) material of 
      9,9-dimethyl-9,10-dihydroacridine-2,4,6-triphenyl-1,3,5-triazine (DMAC-TRZ) as a 
      blue dopant to compose the emission layer for the fabrication of a TADF blue 
      organic-light-emitting diode (BOLED). The device is highly efficient with the 
      following performance parameters: maximum brightness (B(max)) = 57586 cd/m(2), 
      maximum current efficiency (CE(max)) = 35.3 cd/A, maximum power efficiency 
      (PE(max)) = 21.4 lm/W, maximum external quantum efficiency (EQE(max)) = 14.1%, 
      and CIE coordinates (0.18, 0.42). This device has the best performance recorded 
      among the reported solution-processed TADF BOLEDs and has a low efficiency 
      roll-off: at brightness values of 1000 and 5000 cd/m(2), its CEs are close, being 
      35.1 and 30.1 cd/A, respectively. Upon further doping of the red phosphor 
      Ir(dpm)PQ(2) (emission peak lambda(max) = 595 nm) into the blue emission layer, we 
      obtained a TADF-phosphor hybrid white organic-light-emitting diode (T-P hybrid 
      WOLED) with high performance: B(max) = 43594 cd/m(2), CE(max) = 28.8 cd/A, 
      PE(max) = 18.1 lm/W, and CIE coordinates (0.38, 0.44). This B(max) = 43594 
      cd/m(2) is better than that of the vacuum-deposited WOLED with a blue TADF 
      emitter, 10000 cd/m(2). This is also the first report on a T-P hybrid WOLED with 
      a solution-processed emitting layer.
