Abstract: A piezo scanner apparatus is provided to prevent stress concentration during a repeated driving of an actuator, thereby ensuring stable driving. A piezo scanner apparatus(100) comprises a rotor(110), a piezo-electric actuator(120), an elastic member(130) and a base(140). One or more reflecting members(101) are mounted on the rotor. A friction member(121) is positioned in a front end of the piezo-electric actuator. The friction member contacts the rotor. The piezo-electric actuator provides external force for rotating the rotor. The external force is generated by bending and elastic deformation of the piezo-electric actuator when power is applied. The elastic member provides elastic force for pressurizing the piezo-electric actuator towards the rotor in order to maintain a contacting state between the rotor and the friction member. The base comprises axis supporting parts(141a,141b), an actuator arrangement part(142) and an insertion fixation part(143). A rotation shaft(111a) of the rotor is pivotally assembled in the axis supporting part. The piezo-electric actuator is arranged in the actuator arrangement part. The elastic member is fixed to the insertion fixation part.

Abstract: A method for compensating for a physical variation of an optical modulator and a display device are provided to maintain constant brightness of the display device by compensating for a driving voltage according to a deflection variation of a micro mirror. An optical modulator(320) changes brightness in an inlet beam according to a driving signal and outputs a modulation beam. A driving circuit(325) generates the driving signal according to an image control signal and applies the driving signal to the optical modulator. A scanner(330) scans the modulated beam on a screen. A photo detector(350) detects the modulated beam from the optical modulator. A measuring unit(360) measures the brightness of the modulated beam. A controller(370) receives an image signal and applies an LUT(Look-Up Table) on the image signal to convert the image signal to the image control signal, which is supplied to the driving circuit. The controller measures a physical variation of the optical modulator from the brightness of the modulated beam from the LUT and updates the LUT. When the variation exceeds a threshold value, the controller provides an updated driving voltage range signal to the driving circuit.

Abstract: A keystone compensating method and a display device are provided to save calculation resources in a calculation process by performing keystone compensation through a simple calculation, and also save a memory by performing keystone compensation only with a buffer which stores 4-pixel information. An image controller receives an image signal(S910). The image controller sequentially stores pixel data in a buffer memory for keystone correction(S920). Coordinates of a correction pixel and correction pixel data are calculated using three consecutive pixel data among pixel data stored in four pixel buffers of a buffer memory(S930). Keystone correction is completed on all the pixels of a particular row by repeatedly performing the immediately previous process(S940). A corrected image signal with a corrected keystone is obtained with respect to the entire two-dimensional image by repeatedly performing the immediately previous process(S950).
