“…Secondly, some impurity particles in the flexible OLED PI substrate will also affect the TFT characteristics. Finally, the TFT current is mainly concentrated on the device surface, considering the influence of TFT edge effect is also the direction of PBTS improvement (6).…”

There is a bad performance in the image quality of AMOLED display, which is the graininess and the non‐uniformity brought by the graininess. This phenomenon is called Sandy Mura in this paper. After systematic research and analysis, Sandy Mura is divided into three types. These three types of Sandy Mura interfere with each other in observation and judgment, making adverse improvement extremely difficult. In this study, the main elements for several Sandy mura types were experimentally verified, and their distinct mechanisms and models were developed. According to the models, the improvement plan was proposed. After a series of improvements, Sandy mura was finally effectively improved.

“…Most TFTs are made of hydrogenated amorphous silicon (a-Si: H) as the primary material because its energy level is smaller than that of single-crystal silicon. With progress in manufacturing, the TFT resolution tends to be high-definition [ 3 , 4 ] at a comprehensive view illumination coupled to the ultra-high definition and beyond. Thus, the electrode pixel in TFT approaches a smaller and smaller dimension.…”

Light Emitted Diode on Detecting Thin-Film Transistor through Line-Scan Photosensor

This paper explores the effectiveness of the white, red, green, and blue light emitted diodes (LEDs) light sources to detect the third layer of the electrode pixel and the fourth layer of the via-hole passivation on thin-film transistors. The time-delay-integration charge-coupled device and a reflective spectrometer were implemented in this experiment. The optical conditions are the same, as each light source and the digital image’s binary method also recognize the sharpness and contrast in the task. Consequently, the white and the blue LED light sources can be candidates for the light source for the optical inspection, especially for monochromic blue LED’s outperformance among the light sources. The blue LED demonstrates the high spatial resolution and short wavelength’s greater energy to trigger the photosensor. Additionally, the metal material has shown a tremendous responsibility in the photosensor with 150 Dn/nj/cm2 over the sensibility. The mercury 198Hg-pencil discharge lamp emits the stable spectral wavelength to significantly calibrate the spectrometer’s measurement.
