在投影质量的测试中,虽然参测产品的价格区间跨度较大,但在色彩表现和文字投射质量方面的差距并不大,它们都完全可以满足日常办公或教学演示中的投影需求。亮度和对比度方面的差距成为了影响投影质量成绩的主要原因。特别是在对比度方面,即便是同价位段的产品之间也有较大的差距,这主要是因为不同的投影机对暗部亮度的控制能力差异造成的。
In the projection quality test, although the parameterized product has a large price range, the difference between the color performance and the quality of the text projection is not big, and they all can fully meet the projection demand in the daily office or teaching demonstration. The difference in brightness and contrast has been the main reason for the impact on projection quality. Especially in the contrast, even with the price segment of the product there is a big gap between, mainly due to the different projector on the darkness of the control ability of the difference caused.
