Abstract:

A liquid crystal display may have main column spacers and subspacer column spacers. The column spacers may have cross shapes formed from overlapping perpendicular rectangular column spacer portions respectively located on a color filter layer and a thin-film transistor layer. The column spacers may have a hybrid configuration in which some of the rectangular portions on the thin-film transistor layer extend vertically and some extend horizontally. Column spacers may be formed from planarization layer material, may be formed from locally thickened portions of a planarization layer, and may have circular shapes.

International Classification:

H04S 7/00
H04S 1/00

Abstract:

A mobile device with orientation aware audio mapping capability is disclosed. The mobile device has an aux speaker, a loud speaker, a sensor for device orientation detection, and a processor (or processors) coupled to the sensor and the speakers. Depending on the device orientation, the processor sends a mapped audio output to the speakers. The mapped audio output may be a mono audio signal or a stereo audio signal. The stereo audio output signal may be a stereo audio output signal with a balanced or biased audio power distribution between the aux speaker and the loud speaker.

Abstract:

A display may have a color filter layer and a thin-film transistor layer. A layer of liquid crystal material may be located between the color filter layer and the thin-film transistor layer. Column spacers may be formed on the color filter layer to maintain a desired gap between the color filter and thin-film transistor layers. Support pads may be used to support the column spacers. The column spacers and support pads may have comparable thicknesses. Different column spacers may be located at different portions of the support pads to allow the support pad size to be reduced while ensuring adequate support.
