Abstract: A backlight dimming method for backlighting an LCD panel having a variable refresh rate with an LED module, the variable refresh rate having a maximum refresh rate, the LED module having at least one LED sub-zone, the LED sub-zone including a plurality of LEDs, and the method including: using a controller to generate a secondary synchronizing signal having a frequency higher than the maximum refresh rate; and using the controller to update dimming values for the at least one LED sub-zone at one or more pulses of the secondary synchronizing signal with current dimming data after the controller has received the current dimming data from a scaler.

Abstract: A computer apparatus includes a first cover, a second cover, a motherboard, an expansion device and a detach assisting assembly. The second cover is detachably disposed on the first cove, and has an accommodation space and an opening. The motherboard is disposed between the first and second covers. The expansion device disposed in the accommodation space and connected to the motherboard is drawable from the accommodation space through the opening. The detach assisting assembly disposed in the accommodation space includes a slidable member and a rotatable member. The slidable member is slidable relative to the second cover for rotating the rotatable member to drive the first pressing part to press a side of the expansion device away from the opening, and thereby at least a part of the expansion device protrudes from the accommodation space through the opening.

Abstract: An electronic device with a support includes a main body and a support arm. The support arm includes a fixed component and a support component. The support component comprises a pivot end and a leaning end. The support component pivots relative to the fixed component, such that the support arm has a first usage state and a second usage state. When in the first usage state, an acute angle is formed between the support component and the fixed component, and the leaning end of the support component and a bottom edge of the main body both support the main body. When in the second usage state, an obtuse angle is formed between the support component and the fixed component, and the leaning end of the support component is assembled with a seat which is for supporting the main body.

Abstract: The disclosure provides a fixation structure, for accommodating and fixing a storage module, including an accommodating housing. The accommodating housing includes a fixed housing and a movable housing. The fixed housing includes a bottom frame and a side frame. The side frame stands on three adjacent sides of the bottom frame to form an opening therebetween. The movable housing is detachably installed on the bottom frame to close the opening and forms an accommodation room with the fixed housing. The storage module is located in the accommodation room. The fixed housing and the movable housing are made of metal.
