This paper describes a novel method for image contrast enhancement by controlling gamma curve in AMLCD. The key idea is to automatically manipulate gamma voltage in accordance with the image data distribution. This method is applied to 17″ SXGA LCD monitor module. The contrast ratio and the brightness are enhanced by about 3 times and 1.7 times, respectively, by using the proposed method.

Endoplasmic reticulum (ER) has a unique redox environment, which plays critical roles in the organelle's function and in its pathological responses such as ER stress. In this work, we introduce an ER-targeting fluorogenic reactive oxygen species (ROS) chemosensor (ER-Flu) from copper(I)-catalyzed alkyne-azide cycloaddition of 3-propargyl ester of 2 0 ,7 0-dichlorodihydrofluorescein diacetate and N 3-glibenclamide, which were adopted as a fluorogenic ROS sensing module and an ER-targeting module, respectively. Thereby, a series of confocal microscopic experiments of ER-Flu demonstrated that the sensor localizes in ER of the live cells and that ROS are elevated in the cells by ER stress inducers such as thapsigargin, brefeldin A, and tunicamycin.
