TL;DR: In this paper, a display device including a diffraction grating from which a diffracted light of the zeroth order and an order having different color light components emerge to establish color separation is described.
Patent
El display device
TL;DR: In this article, a thin-film EL display device incorporates a MOS active matrix and a Zener diode for the purpose of protecting the device from a high voltage, which has a breakdown voltage characteristic corresponding to a difference between a luminous voltage and a non-luminous voltage of an EL display element.
Patent
Apparatus for controlling data voltage of liquid crystal display unit to achieve multiple gray-scale
TL;DR: In this paper, a data voltage controlling apparatus is provided to achieve digital multiple gray-scale levels with little flickering in a driving device of an active matrix type liquid crystal display unit.
