摘要： A laser projection apparatus includes a reflecting unit, a reflecting diffuser, a first lens array having a length and a width, a condensing lens having first and second lens portions and first and second center axes, a laser set emitting a first color light, an imaging module, and a projection lens. The reflecting unit reflects the first color light to the first lens portion. The reflecting diffuser reflects the first color light to travel along a light-exit axis of the second lens portion. The first lens array is disposed on the light-exit axis. The length along the first center axis and the width along the second center axis are less than or equal to one half of a diameter of the condensing lens and the diameter, respectively. The imaging module is disposed on the light-exit axis. The imaging module and the projection lens receive the first color light sequentially.

摘要： A light source module includes a casing, a first light source disposed in the casing to emit a first light, a first semi-transparent and semi-reflective mirror disposed in the casing and located on an optical path of the first light, and a heat dissipation member disposed in the casing and located on a second axis of the first semi-transparent and semi-reflective mirror. A first part of the first light passes through the first semi-transparent and semi-reflective mirror or is reflected by the first semi-transparent and semi-reflective mirror and then travels along a first axis. A second part of the first light is reflected by the first semi-transparent and semi-reflective mirror or passes through the first semi-transparent and semi-reflective mirror and then travels along a second axis. The first part is more than the second part. The second part of the first light is directed to the heat dissipation member.

摘要： A frame correction method includes the following steps. Firstly, a correction frame is projected, wherein the correction frame has a number of original-boundary contour points. Then, in the first boundary contour adjustment, in response to a position adjustment of the first contour-adjusted one of the original-boundary contour points, correspondingly adjust the position of at least one symmetrical one of the original-boundary contour points, wherein at least one symmetrical one and the first contour-adjusted one are symmetrically disposed. Then, in response to the position adjustment of the first contour-adjusted one, a number of first new boundary contour points and a number of first open correction points are added.

摘要： A projection apparatus and an overheating protection method thereof are provided. An initial stable temperature corresponding to an initial accumulated usage time during an initial usage period is obtained by using a temperature sensor in the projection apparatus. At least one stable temperature respectively corresponding to at least one accumulated usage time is obtained by using the temperature sensor in the projection apparatus. An estimated time corresponding to a target temperature is estimated according to the initial accumulated usage time, the initial stable temperature, the at least one stable temperature, and the at least one accumulated usage time. A temperature protection operation of the projection apparatus is executed in response to a current accumulated usage time of the projection apparatus exceeding the estimated time.

摘要： An electronic device includes a body and a heat dissipation module. The body includes a display, and the display has a display surface. The heat dissipation module is disposed on the display. The heat dissipation module includes a casing and at least one first fan. The casing has a first opening. The first opening faces the display surface. The first fan is disposed in the casing, and the first fan includes an air inlet portion and an air outlet portion. The air outlet portion faces the first opening, wherein an airflow generated by the first fan flows out of the casing from the air outlet portion via the first opening to flow to the display surface. An ambient air outside the casing flows into the air inlet portion of the first fan via the first opening.

摘要： A camera assembly adaptable to a display device is provided. The camera assembly comprises a fixed base, a lifting component, an elastic element and a camera module. The fixed base is disposed in the display device and fixed with the display device. The lifting component is movably connected to the fixed base. The elastic element is connected with the lifting component and the fixed base respectively. The camera module is pivotally connected to the lifting component. The elastic element provides elastic force to drive the lifting component to raise the camera module so that the camera module is exposed from the display device, and the camera module pivots relative to the lifting component to tilt the display device.
