A method of arranging components in an integrated circuit includes providing two or more circuit cells of a first type and providing two or more circuit cells of a second type. The circuit cells of the first type are configured to operate in conjunction with the circuit cells of the second type. The method further includes arranging the circuit cells of the first and second types in an alternating pattern such that each circuit cell of the first type is adjacent to at least one circuit cell of the second type. The alternating pattern may be an array of rows and columns and may include a repeating pattern of one first type cell and one second type cell in each of the columns. The alternating pattern may include a repeating pattern of one cell of the first type and two cells of the second type in each of the columns.

Voltage reference and current source mixing method for video DAC

A method of driving a pixel array includes providing a ramp signal to one or more columns of the pixel array. For each cycle of the ramp signal, the method further includes providing a first row driving signal to at least a first row of the pixel array and a second row driving signal to a second row of the pixel array. A pixel array driver may include a ramp signal generator configured to produce a ramp signal, a first amplifier configured to receive the ramp signal and produce a first amplified ramp signal, and a second amplifier configured to receive the ramp signal and produce a second amplified ramp signal. The first amplified ramp signal may be electrically connected to a first set of pixels of a pixel array, and the second amplified ramp signal may be electrically connected to a second set of pixels of the pixel array.

Two rows driving method for micro display device

A unit pixel driver circuit includes a capacitor configured to store a voltage corresponding to a desired pixel brightness and a control block. The control block may include a first, second third and fourth transistors, all of which are connected together, both in parallel and in series. The control block controls, based on the voltage stored in the capacitor, the amount of current flowing through a pixel LED. The first transistor, second transistor, third transistor and fourth transistor all share a common gate geometry size.
