An active phased array, including multiple antennas, multiple phase shifters, and multiple filters, is provided. The phase shifters are individually coupled to a corresponding one of the antennas. The filters are commonly coupled to a signal feeding line and individually coupled to a corresponding one of the phase shifters. Each filter includes a filter capacitor and a filter resistor. The filter capacitor is coupled between a first node and a second node and has a capacitance. The filter resistor is coupled between the second node and a third node and has a resistance. The first node is coupled to one of the signal feeding line, the second node is coupled to a corresponding one of the phase shifters, the third node is coupled to the ground, and at least one of the capacitance and the resistance is adjustable.

Active phased array

An optical sensing circuit includes a capacitor, and a light sensing unit, a compensation unit, and a switching element coupled to the capacitor. The light sensing unit includes a first light sensing transistor for sensing a first color. The compensation unit includes a second light sensing transistor for sensing a second color. The spectra of the second color and the first color do not overlap each other. When the light illuminates, the light sensing unit generates a first current and the compensation unit generates a second current. The second current reduces the magnitude of the charging or discharging current when the capacitor is charged or discharged by the first current. When the switching element turned on, the voltage of the capacitor is read to determine the color of the light. The voltage level of the gate of the first or second light sensing transistor is adjustable.

Optical sensing circuit and method for determining light color by using the same

A display apparatus includes a display panel, a light guide plate, at least one light source and at least one reflective body. The light guide plate is disposed below the display panel. The light guide plate has a light-incident surface, a light-emitting surface, a rear surface, a plurality of concave microstructures and a plurality of reflective bodies. The rear surface is located farther away from the display panel than the light-emitting surface is. The light-incident surface is connected to the light-emitting surface and the rear surface. The concave microstructures are located on the rear surface. The reflective bodies are respectively located in the concave microstructures. The light source is disposed opposite to the light-incident surface.

Display apparatus

A display panel including a plurality of unit regions is provided. The unit regions are arranged along a first direction and a second direction to form a plurality of columns and a plurality of rows. Each of the unit regions of the display panel includes a plurality of first color sub-pixels, a plurality of second color sub-pixels, and a plurality of third color sub-pixels. In any of the rows, a first pitch between any one of the first color sub-pixels and a next of the first color sub-pixels has at least four kinds of distances.
