Abstract: In various embodiments, a laser emitter such as a diode bar is cooled during operation via jets of cooling fluid formed by ports in a cooler on which the laser emitter is positioned. The jets strike an impingement surface of the cooler that is thermally coupled to the laser emitter but prevents direct contact between the cooling fluid and the laser emitter itself.

Abstract: A display may have a thin-film transistor (TFT) layer and a color filter layer. The TFT layer may have a first substrate, a first black masking layer, a planarization layer, and a layer of TFT circuitry on the planarization layer. The color filter layer may have a second substrate and a second black masking layer on the second substrate. A portion of the inactive area may serve as a logo area for displaying desired information to the user. A reflective structure may be formed on the bottom surface of the planarization layer, on the bottom surface of the first substrate, on the bottom surface of the second substrate, or on the upper surface of the first substrate in the logo area. In another embodiment, the logo area may be backlit by transmitting light through one or more openings in the first and second black masking layers in the logo area.
