49.2: Reduction of LCTV Backlight Power and Enhancement of Gray Scale Capability by Using an Adaptive Dimming Technique

SID Symposium Digest of Technical Papers (2003)

Tomokazu Shiga S. Mikoshiba

Abstract An adaptive dimming technique is introduced for reducing the backlight power consumption in LCTVs. With the technique, the backlight luminance is adjusted according to the input TV signal. For example, when the original input signal is small, the backlight luminance is reduced and the signal is increased so that the perceived luminance is equal to that before the signal processing. From a simulation, backlight power reduction to 1/3 can be expected for APL 25% image. The gray scale capability at low luminance levels is also enhanced.

Alternating Administration of Osimertinib for Leptomeningitis and Docetaxel Plus Ramucirumab for Lung Adenocarcinoma Resistant to Epidermal Growth Factor Receptor Tyrosine Kinase Inhibitors: A Case Report

Internal Medicine (2024)

Hidenori Tomizawa Atsuto Mouri S. Mikoshiba Kasumi Tsukamoto Yukiko Abe

Traditionally, leptomeningitis (LM) has been considered untreatable and terminal, but the development of epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs) has significantly improved the prognosis of patients with EGFR mutations. However, non-LM lesions occasionally progress or recur, even when the LM is successfully controlled with EGFR-TKIs, and treatment of such cases remains unclear. We herein report a patient with advanced non-small-cell lung cancer (NSCLC) who was treated with an EGFR-TKI for LM and cytotoxic chemotherapy for EGFR-TKI-resistant pulmonary lesions. The patient survived for almost four years after the diagnosis of LM, suggesting that this treatment may be beneficial in advanced NSCLC with EGFR-TKI-sensitive LM and EGFR-TKI-resistant extracranial lesions.

34.1: High‐Luminance and High‐Efficacy Electric‐Field‐Coupled Discharge Lamp for 18‐in. Diagonal LCD Backlighting

SID Symposium Digest of Technical Papers (1999)

K. Hashimoto Y. Ikeda Tomokazu Shiga K. Igarashi S. Mikoshiba

Abstract A flat lamp is developed for an 18‐in.‐diagonal LCD backlighting, using 8 electric‐field‐coupled discharge tubes. All the tubes can be driven with a single inverter circuit. Luminance, efficacy, and input power are 3500cd/m 2 , 34 lm/W, and 35W when the lamp is driven at 5.24MHz and 790V.

A flat gas-discharge panel TV with good color saturation

IEEE Transactions on Electron Devices (1975)

M. Fukushima Seiichi Murayama T. Kaji S. Mikoshiba

A flat 8-in diagonal gas-discharge color-TV has been fabricated and operated at 5 fL in white with a luminous efficiency of 0.05 lm/W. The contrast ratio was measured at better than 300:1, owing to the special configuration of the discharge cell, and also the careful adjustment of gas loading conditions. The CIE chromaticity coordinates for red, green, and blue (R,G,B) exhibited in the panel were, respectively, (0.56,0.31), (0.22,0.68), and (0,17,0.14)-- reasonably good values considering those of NTSC. The electrical and optical properties of the panel as well as the techniques for real-time TV picture display are discussed.

Control of repetitive electrical discharges by means of an external electrode

Journal of Applied Physics (1992)

F. L. Curzon R. W. Cobb S. Mikoshiba

It is shown that the amplitude of flattopped pulses needed to maintain repetitive interelectrode discharges in a discharge tube can be reduced by applying a similarly shaped voltage pulse of opposite polarity to an external metal sheet coplanar with the cathode of the discharge tube. An explanation of the effect, based on the relative timing and amplitude of the various voltage pulses applied to the discharge system, is advanced. It is also shown how the effect may be of significance in controlling gas discharge display panels.

A virtual pixel technique for doubling the PDP resolution of moving images

Journal of the Society for Information Display (2002)

Tomokazu Shiga S. Mikoshiba K. Kariya

Abstract— A virtual pixel technique increases the resolution of spatially discrete pixilated display devices when the eye moves relative to the screen. By using this technique, an effective PDP resolution can be doubled for moving images. For instance, 1280‐horizontal‐pixel data can be displayed on a VGA PDP having only 640 horizontal pixels. The positions and sizes of the virtual pixels are controlled by choosing light‐emission timings and durations of the actual pixels as their images move across the retina.

26.3: Evaluation of Motional Artifacts on PDPs Appearing with Arbitrary Motion of Observation Points

SID Symposium Digest of Technical Papers (2000)

K. Sawa Tomokazu Shiga S. Mikoshiba T. Ohe Koki Toda

Abstract An evaluation technique is introduced for artifacts appearing on PDP images when the eye of an observer does not follow the motion of the images. The motional artifacts are serious especially when the eye moves arbitrarily. Dividing the light‐emission periods of sub‐fields into smaller blocks, and adding equalizing pulses to the original signal are effective in reducing the disturbances.
