Besides, an electronic device includes a frame, a housing, and the above panel assembly, and the housing and the panel assembly are installed in the frame.

Abstract: A light-emitting universal serial bus socket is provided. The structure comprises a housing, an electrical connection board, and a light-emitting unit. The electrical connection board is disposed in the housing. The electrical connection board is a light-guiding structure. In addition, the light-emitting unit is disposed on one side of the electrical connection board. The light-emitting unit emits light, which passes through the electrical connection board and light up. The universal serial bus socket according to the present invention has the light-emitting effect, which facilitates identifying plugs in nocturnal applications as well as enriching creativity.

Abstract: An electronic device holder is revealed. The electronic device holder includes a main body, an adjustment member, a fixing part and at least one stopper. The main body consists of a supporting part and a blocking part. An electronic device is arranged at the blocking part while the supporting part holds the electronic device and the stopper is against the electronic device. One end of the adjustment member is fixed on the supporting part and the other end thereof is attached to the fixing part. An angle between the supporting part and the blocking part is adjusted by the adjustment member and the fixing part. Thus the mounting angle of the electronic device meets users' needs. The angle between the supporting part and the blocking part is changed along with the position of the adjustment member attached to the fixing part.

Abstract: The present invention provides an all-in-one converter structure, which has a plurality of plugs each having a different type of connector. A user can choose an appropriate connector from the plurality of plugs. The plurality of plugs are connected with each other via at least a flexible connecting member. Thereby, no loss problem of plug will occur. In addition, the flexible connecting member are more damage-resistant than rigid connecting members.

Abstract: The present invention provides a composite charging cradle for charging rechargeable batteries of several different specifications to solve the problem of confusion between the specifications of rechargeable batteries. The charging cradle includes a cradle body and a circuit board disposed in the cradle body. The cradle body has a plurality of insertion slots for inserting rechargeable batteries of different specifications therein, and each of the insertion slots is provided therein with at least one set of terminals for outputting power; the circuit board is disposed in the foregoing cradle body, including a plurality of power input ports of different specifications exposed out of the cradle body, and an integrated unit for integrating all the foregoing power input ports; the integrated unit is electrically connected with each set of terminals such that rechargeable batteries and plug adapters of several different specifications can be charged according to the present invention.

Abstract: A color management system for display device includes a color management controller, a color sensor, and an advance function module configured to implement a process (a) or a process (b) applied to multiple PWM signals generated from the color management controller. Process (a) includes the steps of using a reset signal generated by and synchronized with an image signal, and a counter with special bit length and counting frequency to generate a reference signal synchronized with the image signal, and using the reference signal to synchronize the PWM signals with the image signal as output. Process (b) includes the steps of using a reset signal with special frequency and a counter with special bit length and counting frequency to generate multiple synchronized reference signals with respective different phases, and generating multiple synchronized PWM signals with respective different phases as output by the use of the reference signals.

Abstract: A liquid crystal display includes a scaler module, a field-programmable gate array (FPGA) module, a buffer, a backlight module and a LCD module. The FPGA module includes a regional peak detector, a backlight control unit and a pixel value control unit. The regional peak detector is configured for detecting a maximum pixel value of each image region of each image. The backlight control unit is configured for selectively adjusting the backlight brightness of one or more image regions of each image. The pixel value control unit is configured for adjusting pixel values of the one or more image regions of each image by shifting binary pixel values to compensate for the influence of backlight adjustment. A method for adjusting backlight brightness of a liquid crystal display is also provided.
