A Complete Exciton Diffusion Model Including Both Singlet and Triplet behavior Couple with Poisson and Drift-Diffusion Solver
Jun-Yu Huang;Kung-Chi Hsu;Chia-Hsun Chen;Tien-Lung Chiu;Jiun-Haw Lee;Yuh-Renn Wu
In this work, we developed a complete exciton diffusion model to help researchers to understand and analyze exciton behavior in organic light-emitting diodes (OLEDs), especially triplet-triplet fusion and thermally activated delayed fluorescence OLEDs. This exciton diffusion model considers both singlet and triplet exciton to simulate OLEDs performance successfully, which includes singlet-singlet quenching, triplet-triplet quenching, triplet-singlet annihilation, triplet-triplet annihilation.

Defect Inspection System of Direct-Light Backlight and Human Visual Judge System of Just Noticeable Difference
Si Min Chou
We have considered the problem that the backlight image will cause serious LED brightness's unevenness in the insufficient light mixing distance. Experimental results have shown that the proposed method can successively detect and locate defects in a direct-light backlight, achieve the purpose of high-speed development process and efficient products management.

Using Hopkin’s equation to simulate optical lithography
Snow H. Tseng;Ta-Wei Hsiao
We presented a numerical result for computation lithography patterns using Hopkins’s equation. We investigated the lithography patterns under different sources wavelength and numerical apertures. We observed that the line width of the pattern increases as the numerical aperture NA changes from 1.56 to 1.2 due to the diffraction effect.

Reduced Viewing Distance of LED Displays by Increasing Effective Emitting Area of LED through Light Diffuser Films
Chi-Cheng Lung;Li-Yin Chen
In this work, the minimum required viewing distance of a large-size LEDs with pixel pitch of 4 mm was reduced by covering optical diffusers. The light passed through the diffuser from LED was re-distributed evenly to hide the LED hot spot and increase the effective emitting area. The minimum required viewing distance decreased from 11.4 m to < 5 m with the high effective emission area, but also caused some side effects which may downgraded image quality. We used MTF calculated by the LSF to compare the evaluate image quality.
