A multi-winding high step-up DC-DC converter includes a three-winding transformer to transform a low DC voltage to a high DC voltage; a power switch to control the energy flux of the primary winding of the three-winding transformer based on turning on/off the power switch; a first diode to control the current of the first secondary winding of the three-winding transformer; a second diode to control the current of the second secondary winding of the three-winding transformer; and a third diode to control the current of the primary winding. When the DC-DC converter is in the first operation state, the switch and the second diode are in on state, and the first and the third diodes are in off state. When the DC-DC converter is in the second operation state, the switch and the second diode are in off state, and the first and the third diodes are in on state.

The invention provides an antiglare film. A resin layer is disposed on a substrate. Micro-aggregates are distributed in an interior and over a surface of the resin layer. Each of the micro aggregates has a size of 0.1-3 μm and is formed by aggregating aggregated nano-particles. The micro-aggregates distributing over the surface result in a surface roughness of the resin layer. The weight ratio of the resin layer to the micro-aggregates is 1:0.1-0.7.

The invention relates to a lamp frequency control system for a display and method for controlling the lamp frequency. The lamp frequency control system comprises a driving control device and a lamp frequency control device. The driving control device has a driving mode selector for selecting a driving mode from at least two driving modes. According to the selected driving mode, the driving mode selector outputs at least one corresponding frequency control signal. According to the corresponding frequency control signal, the lamp frequency control device obtains at least one corresponding lamp frequency. According to the various driving mode, the lamp frequency control system of the invention obtains the corresponding lamp frequency. That is, the lamp frequency can be adjusted to match the driving mode. Therefore, the lamp frequency can be adjusted at a frequency section without the water flow interference. The lamp frequency control system of the invention can resolve the water flow interference.
