摘要： A semiconductor device with reduced power consumption and a display device including the semiconductor are provided. The semiconductor device generates a bias voltage that is to be supplied to a buffer amplifier. When the display device displays a still image, a data signal for updating the image need not be supplied from the buffer amplifier to a pixel array in the next frame; therefore, the circuit is configured so that the buffer amplifier is brought into a standby state (temporarily stopped). Specifically, input of a reference current from a BGR circuit to the semiconductor is stopped and a bias voltage is applied from the semiconductor device to the buffer amplifier to temporarily stop the operation of the buffer amplifier.

摘要： This disclosure provides systems, methods, and apparatus for providing pixel circuits for controlling the state of operation of light modulators in a display device. The state of operation of the light modulator is controlled by the pixel circuit based on a data voltage stored in a data storage element of the pixel circuit. The pixel circuit includes a compensation capacitor, which is used to inject charge into the data storage element. In some implementations, this injection of charge boosts the voltage across the data storage capacitor thereby improving the reliability of the pixel circuit.

摘要： A brightness compensation system and method of providing brightness uniformity in an active-matrix organic light-emitting diode (OLED) flat-panel display. The brightness compensation system of the present invention includes a system controller, a timing generator, a test brightness generator, a pixel address generator, a video formatter, a first and second multiplexer, a memory device, a pixel adjust device, a level shifter and driver, a current sensor, an analog-to-digital converter, a DC power supply, and an active-matrix OLED display under test. The brightness compensation system and method of the present invention subjects an active-matrix OLED display to a testing operation that alternately tests every pixel, detects its output current, which is an indicator of light output level, for a given input voltage, saves the output current value in memory, then applies a corrective voltage to each pixel, so that each pixel has the same light ouput (output current) as its neighboring pixel.

摘要： A display matrix is provided for forming a composite image from a series of sub-images. In general, the display matrix includes a plurality of display elements, each display element including a pixel, and a display circuit electrically connected to the pixel. An illumination source illuminates each of the pixels. Logic controls the intensity of each pixel utilizing a digitally controlled waveform for controlling a duration of time that illumination is allowed to pass through liquid crystal of the display elements. A method for driving a digital display is also provided. Each of a plurality of pixel timers is set with an intensity value, where the pixel timers are associated with pixels of a display. The pixels of the display are set to a first state. Each of the timers is initiated. Illumination is applied to the display. Each of the pixels is switched to a second state upon expiration of the timer. The process is repeated for a predetermined number of times for generating an image. A method for producing a grayscale image on a digital display is also provided according to an embodiment of the present invention. Intensity values for each of the pixels are stored in pixel memories that are each associated with the individual pixels of a display. Each of the pixels is set to a first state. A first intensity level is broadcast to the pixels. The first intensity level is analyzed with the intensity values stored in the pixel memories. The pixels whose associated intensity value matches the first intensity level are switched to a second state. Illumination is applied to the display. A predetermined amount of time is allowed to transpire. A next intensity value is broadcasted to the pixels. The next intensity level is analyzed with the intensity values stored in the pixel memories. The pixels whose associated intensity value matches the next intensity level are switched to the second state. The final two steps of the process are repeated for each level of desired intensity.

The differential amplifier includes a Kth-power of 2 pieces of differential pairs each driven by an individually received tail current, and a tail current control circuit that individually supplies the tail current to the Kth-power of 2 pieces of the differential pairs. The tail current control circuit sets a current ratio of the tail current flowing through of two respective differential pairs among the Kth-power of 2 pieces of the differential pairs to be larger than a current ratio of the tail current flowing through other respective differential pairs excluding the two differential pairs.
