Abstract: In a backlight assembly and a liquid crystal display apparatus, a plurality of lamps disposed in a receiving space of the backlight assembly is spaced apart from each other by various intervals between the lamps depending upon positions at which the lamps are disposed. Each of the lamps may also have an external electrode having a different area from each other or due to the positions at which the lamps are disposed. Furthermore, each of the lamps may have a different amount of discharge gas injected thereinto due to the positions at which the lamps are disposed. Accordingly, the liquid crystal display apparatus may provide a uniform brightness, and prevent deterioration of display quality thereof.

Abstract: Provided is a method for analyzing the performance of an OLED through activation in-situ. The method includes placing the OLED in an in-situ chamber, driving the OLED, and analyzing a dark spot and/or thermal degradation of the OLED, such that performance of the OLED can be analyzed while driving the OLED in-situ, separated from the external environment.
