    Abstract: An optical module includes a mirror unit including a mirror holder and a mirror on the mirror holder, the mirror holding including a first plate; a center guide supporting the mirror unit; and an actuator configured to rotate the mirror unit about a rotation axis. The actuator includes a first actuator at the first plate and second and third actuators at second and third plates, respectively, and spaced from each other in a direction parallel to the rotation axis, and the first actuator is configured to be acted upon by the second and third actuators to rotate the mirror unit about the rotation axis.

    Abstract: A display apparatus includes a display region and a peripheral region adjacent to the display region. The display apparatus further includes a first flexible substrate (FFS), a driving circuit (DC), a conductive pattern (CP), a conductive line, a light-emitting device, and a support substrate. The FFS includes a first surface and a second surface opposite the first surface. The second surface includes, in the peripheral region, a cavity extending into the FFS. The DC is on the first surface and includes at least one transistor. The CP is in the cavity and is partially exposed by the cavity. The conductive line electrically connects the CP to the DC. The light-emitting device is in the display region and is electrically connected to the DC. The support substrate is on the second surface. In a view normal to the second surface, the support substrate is spaced apart from the CP.

    Abstract: A laser crystallizing apparatus includes a first light source unit configured to emit a first input light having a linearly polarized laser beam shape. A second light source unit is configured to emit a second input light having a linearly polarized laser beam shape. A polarization optical system is configured to rotate the first input light and/or the second input light at a predetermined rotation angle. An optical system is configured to convert the first input light and the second input light, which pass through the polarization optical system, into an output light. A target substrate is seated on a stage and output light is directed onto the target substrate. A monitoring unit is configured to receive the first input light or the second input light from the polarization optical system and measure a laser beam quality thereof.
