摘要： An electro-optical device includes a plurality of digital scanning lines, a digital signal line, and a plurality of pixel circuits. Each of the pixel circuits includes a light emitting element and a digital driving circuit. The digital driving circuit performs digital driving to turn the light emitting element ON-state or OFF-state based on a grayscale value. The digital driving circuit keeps the light emitting element ON-state by supplying a drive current to the light emitting element, in a period in which an enable signal is active, of a grayscale display period having a length corresponding to the grayscale value. The control line driving circuit sets a period in which the enable signal is active. A ratio, with respect to the grayscale display period, of an ON-state period in which the light emitting element is ON-state changes in accordance with the period in which the enable signal is active.

摘要： The electro-optical device includes a plurality of digital scanning lines, a plurality of analog scanning lines, a digital signal line, an analog signal line, and a plurality of pixel circuits. Each of the pixel circuits includes a light emitting element, a digital driving circuit, and an analog driving circuit. The digital driving circuit performs digital driving in which a drive current is supplied to the light emitting element in a period of a length corresponding to a grayscale value. The analog driving circuit performs analog current setting in which a current value of the drive current is set based on an analog data voltage. In a period in which the pixel circuit connected to an s-th digital scanning line and an s-th analog scanning line performs the analog current setting, the pixel circuit connected to a t-th digital scanning line and a t-th analog scanning line performs the digital driving.

The second transistor is disposed between the data line and an input of a first inverter. The third transistor is disposed between an output terminal of a second inverter and the input of the first inverter. When the second transistor turns from an OFF-state to an ON-state, the third transistor is not in an ON-state.

摘要： In a magnetic field measurement apparatus, a light source irradiates a gas cell with linearly polarized light serving as pump light and probe light in a Z axis direction, and a magnetic field generator applies, to the gas cell, a magnetic field Ax which is a time function f(t) having the amplitude A0 taking n fixed values fi (where i=1, . . . , and n), and a magnetic field Ay which is a time function g(t) having the amplitude A0 taking m fixed values gj (where j=1, . . . , and m) in each of X axis and Y axis directions. A calculation controller calculates a magnetic field C (Cx, Cy, Cz) of a measurement region using the X axis and Y axis components Ax and Ay of an artificial magnetic field A, and a spin polarization degree Mx corresponding to a measurement value W− from a magnetic sensor.
