Abstract

A liquid crystal display includes inverters, a cover, a liquid crystal display panel, and a backlight. The inverters mechanically couple a cover which supports a liquid crystal display panel and a backlight. Each of the inverters is spaced apart from a substantial heat generating electrode region. The inverters are configured to supply power to the backlight. One method of assembling a liquid crystal display includes positioning the inverters; disposing a reflecting sheet below the inverters; electrically coupling the inverters to a light source; mechanically coupling the inverters to the cover; and disposing a plurality of electrodes above the inverters such that the inverters and portions of the electrodes do not lie in a common vertical plane.

Claims (39)
