Abstract: An optical measurement apparatus includes a color analyzing device and an abutting member. The color analyzing device includes a light collecting portion, a body and a connecting portion. The light collecting portion is configured to face to a device under test (DUT) and collect a light emitted from the DUT. The body is configured to measure and analyze the light. The connecting portion connects between the body and the light collecting portion along an axis. The abutting member is tubular and extends along the axis. The abutting member has a first rim and a second rim opposite to the first rim along the axis. The connecting portion penetrates through the first rim and connects with an inner wall of the abutting member. The second rim defines a first abutting surface inclined by a measurement angle relative to the axis and configured to abut against the DUT.

Abstract: A processing method for a plurality of image sources, for a display device includes inputting a plurality of image sources; detecting the plurality of image sources according to metadata of the a plurality of image sources to determine electro-optical transfer function (EOTF) corresponding to the a plurality of image sources; and dynamically applying different EOTFs on corresponding image sources.

Abstract: A method for adjusting frame brightness is provided. First, an image data in YUV format is received. Next, a dimming curve is determined according to an overall average pixel level value of the image data and a number distribution of pixel level values. Then, the image data is divided into a plurality of blocks, and a block average pixel level value of pixels in each of the blocks is calculated. Thereafter, the block average pixel level values are substituted into the dimming curve to obtain a plurality of block brightness values. Afterward, the image data is outputted and backlight sources corresponding to each of the blocks are driven to provide the block brightness values to each of the blocks for displaying a frame.

Abstract: A color adjusting method for a display is provided. The color adjusting method includes establishing a primary color adjusting mode in an on-screen-display (OSD) menu of the display, wherein the primary color adjusting mode at least has one of red, green and blue color adjusting mode items; providing a standard test video signal to the display so as to make that the display displays a standard test pattern; and when one of the red, green, blue color adjusting mode items under the primary color adjusting mode is turned on, attenuating (green and blue)/(red and blue)/(red and green) components in the standard test pattern, so as to make that the display only displays one of the red, green, blue components in the standard test pattern, and thus adjusting one of the red, green, blue colors by users.

Abstract: A method for increasing a frame contrast ratio is suitable for a liquid crystal display (LCD) having a direct-type light emitting diode (LED) backlight module. The method includes establishing a local dimming demo mode in an on-screen-display (OSD) menu of the LCD, so as to determine to turn on or turn off a local dimming control function. Besides, according to this method, when the local dimming demo mode is turned on, the local dimming control function is continuously and repeatedly turned on or turned off in the direct-type LED backlight module in a time-division manner based on image contents in the whole frame of the LCD, so as to increase the frame contrast ratio of the LCD.

Abstract: A multimode integrated modulation circuit for controlling the fan rotating speed mainly includes a voltage regulating circuit, an integrated modulation circuit and a fan motor driving circuit. The voltage regulating circuit is used to receive an external voltage signal and regulate the external voltage signal to a suitable range of workable voltage and then a first output voltage is generated. The integrated modulation circuit that is electrically connected with the voltage regulating circuit is used to receive a PWM signal with a duty cycle and a second output voltage is accordingly generated depending on the product of the duty cycle of PWM signal and the first output voltage. The fan motor driving circuit is used to receive the second output voltage and decide the fan motor rotating speed depending on the second output voltage. Therefore, the present invention substantially adopts low-price circuit elements to integrate voltage regulating mode and PWM mode for controlling the fan rotating speed.

Abstract: A circuit for generating a linear current control signal and method thereof is provided so that the error between the input voltage and the linear current remains constant. The circuit of the invention comprises a resistor, an operational amplifier and a MOSFET, which forms an ideal linear relationship between an input voltage and an output current. The operational amplifier generates a gate-controlled voltage when a reference voltage and an input voltage are inputted thereto. The gate voltage turns on the MOSFET so that a linear current control signal is outputted from the source of the MOSFET.
