This paper presents a full-HD autostereoscopic display with a wide viewing zone based on time-division multiplexing slanted parallax barrier with subpixel-based slit control. A slanted directional diffuser placed between the barrier panel and the image panel suppresses moir_ by mixing light from RGB subpixels. By constituting the parallax barrier along with this slanted diffusion line, control of the barrier by subpixel unit is enabled. By introducing subpixel-based phase shift and slit width control to time-division quadruplexing parallax barrier, viewing zone free from crosstalk is enlarged notably. Theoretical viewing zone is calculated and compared with the experimental results using a prototype hardware. The overall crosstalk of the prototype is also measured to confirm the effectiveness of the proposed method.

The aim of this study was to determine the relationships between free testosterone (FT) level and parameters including laboratory data and data from questionnaires and to determine symptoms leading to the detection of late onset hypogonadism (LOH). We retrospectively reviewed medical records of patients in whom serum FT was measured in our hospital. Aging Male Symptoms (AMS) score, self-rating depression scale (SDS) and frequency scale for the symptoms of gastroesophageal reflux disease (FSSG) score were used for questionnaires. A total of 205 patients were included in the analysis (55.2 ± 15.6 years of age, mean ± SD). Among them, 119 patients (58.0%) had an FT level of less than 8.5 pg/mL, which fulfills the diagnostic criterion of LOH syndrome according to the clinical practice manual for LOH in Japan. It was revealed that FSSG score was inversely correlated to serum FT levels (r = –0.3395, p < 0.001), although SDS and AMS scales did not show significant correlations to FT levels. Our study revealed a high prevalence of LOH syndrome among patients in whom the majority complained of general symptoms. Although GERD symptoms are generally not considered to be typical symptoms of LOH, our study indicates that those symptoms might be clues for the detection of LOH.
