Problems solved by technology

If it is started at an ambient temperature lower than its normal specification, it will cause some abnormal functions or actions, and if it is an electronic component that is abnormal when it is started at such a low temperature, even if the ambient temperature has risen to the electronic component specification within the temperature, it still will not return to normal operation

Embodiment Construction

[0023] Please refer to FIG. 1 , which shows a schematic diagram of applying the technology of the present invention to a display device. For convenience of description, only components related to the present invention are shown in the figure, and other components in the display device not related to the present invention are not shown. As mentioned above, the display device used in the present invention often has a small number of key parts that are not suitable for starting at low temperature. If the key parts are abnormal after starting at low temperature, even if the ambient temperature has risen When the minimum operating temperature within the specification of the component is exceeded, the component still cannot resume normal operation, resulting in abnormal function of the overall display device.

[0024] To solve the problem of starting at low temperature, the display device applying the present invention includes a heating unit 10 , a temperature detection unit 20 , a...

Abstract

A display device that can start in low temperature is disclosed, the heating element in the display device or the external heating element is used to increase the ambient temperature in the display device, when the temperature in the display device reaches the starting temperature of the display device, and the display device can be started in low temperature.

Description

technical field [0001] The invention relates to a display system, in particular to a projection display system which can be started at low temperature. Background technique [0002] With the prosperity of globalized international trade, the products produced by human beings are no longer limited to the transactions in the adjacent areas of origin. On the contrary, through the trend of product internationalization, high-quality and low-cost products are more globally competitive and circulated. However, the local conditions, customs, and geographical climates are different around the world. Therefore, in order to make the products more in line with the differences of various places, it is necessary to adjust the products to varying degrees. Among them, one of the more important considerations is the impact of climate, because climates around the world are completely different, with different cold, hot, dry and wet, and different climate environments often affect the function...
