A display includes a backlight portion having at least one broad spectrum emitter and at least one narrow spectrum emitter, a liquid crystal panel for displaying an image by spatial light modulation, and control electronics configured to receive input image data and output control signals to both the backlight portion and liquid crystal panel. After engine startup until the catalyst is activated, the NOx in the exhaust gas is adsorbed at the NOx adsorbent. The RF duplexer may also include a BAWR receiving filter unit including an input end to receive the balance signal from the dual-output port, and an output end used for dual output. An th transmittal timestamp and an nth transmittal timestamp are determined. The respective phases have an average minor-axis size of 40 nm to 2 \u03bcm.
