A modular laboratory cabinet assembly consists of a pair of identical housing end units arranged in an inverted spaced apart relations to each other, and at least a pair of identical base housing modules arranged in an inverted side by side relations to each other and interposed between the housing end units. The camera enhancement case includes a housing having a front wall and four sidewalls sized for receipt of a cellular telephone. The circuit can also include driving line switches selectively connecting the power sources to the driving lines, channel switches selectively connecting the sensing channels to the sensing lines, and a bypass line allowing the driving line to be connected to the sensing line by operation of the channel switches. A nozzle orifice is formed by electrical discharge machining from the lower side of the base material. Further, the transmission rate of the liquid crystal panel and the light intensity of the backlight module may be relatively lowered down, which also reduces the costs. The bit-line and the bit-line bar are configured to carry complementary bit-line signals.
