Abstract: A method includes receiving a wafer, measuring a surface topography of the wafer; calculating a topographical variation based on the surface topography measurement performing a single-zone alignment compensation when the topographical variation is less than a predetermined value or performing a multi-zone alignment compensation when the topographical variation is greater than the predetermined value; and performing a wafer alignment according to the single-zone alignment compensation or the multi-zone alignment compensation.

Abstract: A backlight module includes a supporting plate, a light source module, and an optical modulation film. The light source module includes a plurality of light sources disposed on a supporting surface of the supporting plate. The optical modulation film is disposed above the light source module and has a plurality of light emitting holes. Light from the light source module is distributed by the optical modulation film and emitted via light emitting holes at different positions. The optical modulation film has a periphery area and a central area. An average perpendicular distance between the periphery area and the supporting surface is different from an average perpendicular distance between the central area and the supporting surface.

Abstract: The present invention provides a backlight module with optical control film, comprising a light source module and an optical control film. The backlight module comprises at least one block corresponding to at least one light source. The projection position of the light source on the block is surrounded by first light emitting holes. The first light emitting hole of the optical control film has a first opening on a surface toward the light source module and a second opening on the other surface away from the light source module. The position of distal end of the first opening relative to the light projection position is further away from the light projection position than the position of distal end of the second opening thereof relative to the light projection position in the direction parallel to the optical control film.

Abstract: A portable electronic apparatus and a control method thereof are provided. The portable electronic apparatus comprises a display, a first system and a second system. The first system and the second system comprise a first processor and a second processor, respectively. The first processor executes a first operating system to generate a first operating system image, while the second processor executes a second operating system to display a second operating system image on the display. The first processor and the second processor respectively execute a first remote desktop program and a second remote desktop program to set up network communication protocol. When the display wants to display the first operating system image, the first operating system image is displayed on the display via the network communication protocol.

Abstract: A method and an apparatus for measuring a depth of field (DOF) are disclosed. The DOF measuring method includes the following steps. Firstly, an image is captured in each of a plurality of focus scales respectively, wherein each image respectively includes an image region corresponding to the same image area. Next, one of the image regions is selected as the best DOF region. Then, a DOF value corresponding to the focus scale corresponding to the best DOF image region is determined according to a lookup table.

Abstract: The present invention discloses an automatic white balance control system, an automatic white balance module, and a method thereof. The automatic white balance (AWB) control system calculates a distance value from a coordinate related to the image to a reference point in a color space coordinate system for each image. If the median or mean of the distance values is greater than a threshold value, an automatic white balance operation will be performed. The system dynamically adjusts the threshold value to prevent a blinking caused by the automatic white balance. The white balance module selects an image block of a higher image sharpness to perform a gain adjustment to prevent a monochromatic block from misjudging a white balance gain.

Abstract: A direct-type backlight module and a lamp holder thereof are disclosed. The lamp holder includes a plurality of lamp seats, and a plurality of connecting arms each connected with at least one adjacent lamp seat. Each lamp seat has a retaining portion for retaining a corresponding lamp therein. Each connecting arm has a bendable portion that can be bent along a horizontal direction so as to adjust a distance between adjacent lamp seats. Therefore, the lamp holder of the present invention has a capability to retain several lamp groups spaced at different intervals for different LCD types or with lamp assembly tolerances, and thereby achieves a higher convenience in the LCD assembly.

Abstract: A back light unit adapted to provide light to a liquid crystal display panel includes a housing, at least a light generator, and an optical filter. The light generator is disposed inside the housing for generating white light beams. The optical filter is disposed in an optical path of the white light beams between the light generator and the liquid crystal display panel for filtering the white light beams within a particular wavelength range of visible light. The hue of the white light beams before and after passing through the optical filter are the same.
