A liquid crystal display module including a liquid crystal display having a plurality of liquid crystal cells, a plurality of switches and a common connection, each liquid crystal cell being connected between a respective switch and a common connection. The common connection includes strips, each extending in a first direction and the strips being arranged side-by-side in a second direction. The liquid crystal cells are arranged in rows, each row being along and connected to a strip. The liquid crystal display has gate lines, each gate line operating a respective plurality of the switches. For dot inversion, each gate operates switches connected to respective liquid crystal cells of two adjacent rows. For each row, a first set of alternate liquid crystal cells are connected to respective switches operated by a respective gate line and a second set of interspersed liquid crystal cells are connected to respective switches operated by another respective gate line.

Liquid crystal display module

An ambient light detection device for use with a liquid crystal display having an array of liquid crystal cells, each liquid cell having at least one transistor for selectively connecting that liquid crystal cell to a signal line and each transistor having a gate connected to a gate line and having a gate supply line selectively connectable to the gate line for turning off the gates. The device includes a current measuring circuit configured to measure the current flowing in the gate supply line as a result of gate leakage current in the gates to which the gate supply line is connected and a controller connected to the measuring circuit and configured to calculate, from the measured current, the level of ambient light reaching the gates.

Ambient light detection device

A differential oscillator circuit, including an oscillator having a first side and a second side and bias circuitry for applying a bias voltage to the first and second sides of the oscillator wherein the bias circuitry is arranged such that, upon start-up, the bias voltage is not applied to the second side of the oscillator until after the first side of the oscillator by a delay period.

Differential oscillator having two sides, an integrated circuit including the differential oscillator, a mobile telephone including the differential oscillator, and method of operating the differential oscillator

A method of receiving and demodulating a plurality of digital signals transmitted with different respective carrier frequencies and a digital receiver for receiving and demodulating a plurality of digital signals transmitted with different respective carrier frequencies wherein the carrier frequency signals are down converted to respective base-band signals and digitized and a common demodulator is provided to demodulate the respective digitized base-band signals in a time division manner.
