Search Symbol (Half-width)	Description of Search Symbols
Space	"AND" indicates the intertwining of key terms used in a search
Double Quotation Marks ("") ( " " )	Double quotation marks indicate the beginning and end of a phrase, and the search will only include terms that appear in the same order of those within the quotations. Example: "image process" ： " image process "
?	Indicates a variable letter. Entering two ? will indicate two variable letters, and so on. Example: "Appl?", search results will yield apple, apply… e , appl y … ( (often used to English word searches) )
*	Indicates an unlimited number of variable letters to follow, from 1~n. Example: Enter "appl*", search results will yield apple, apples, apply, applied, application…(often used in English word searches) e , appl es , appl y , appl ied , appl ication … ( (often used to English word searches) )
AND、OR、NOT	Boolean logic combinations of key words is a skill used to expand or refine search parameters. (1) AND (1) AND: Refines search parameters (2) OR (2) OR: Expands search parameters (3) NOT: Excludes irrelevant parameters

DOI stands for Digital Object Identifier （ D igital O bject I dentifier ） ,
and is the unique identifier for objects on the internet. It can be used to create persistent link and to cite articles.

Using DOI as a persistent link

To create a persistent link 「 https://doi.org/ 」 before a DOI.
For instance, if the DOI of an article is 10.5297/ser.1201.002 , you can link persistently to the article by entering the following link in your browser: https://doi.org/ 10.5297/ser.1201.002 。
The DOI link will always direct you to the most updated article page no matter how the publisher changes the document's position, avoiding errors when engaging in important research.

Cite a document with DOI

When citing a document with a DOI, the DOI permanent URL should always be presented (if using APA or Chicago format, present https://doi.org/DOI number). If using a citation format that does not specify DOI, the DOI permanent URL should still be presented as a priority.

DOIs allow accurate citations, improve academic contents connections, and allow users to gain better experience across different platforms. Currently, there are more than 70 million DOIs registered for academic contents. If you want to understand more about DOI, please visit airiti DOI Registration （ doi.airiti.com ）。

Parallel Abstract 〈TOP〉

With the progress of science and technology of the times, the projection display is no matter at commercial meeting, home theater or larger use; all have certain taking rate of market. But the traditional projector has some defects which are life-time and color. So we propose a novel projection light source of display in this paper, has long life-time, color, high efficiency and high performance of uniformity in the projection display. In the microfabrication the times, that will be an advantage.
We introduced and compared the four types of projector and regard as our design in the digital micro-mirror device type of the projector, this is called DLP. We design the illumination system with new light source which is built in digital micro-mirror device projection display of TIR prism type and compare the traditional lamp light source and laser light source system with the same projector structure in this paper. Our system has 73.55% of the system efficiency, 99.3% of the ANSI Uniformity and 131% of the NTSC area (under CIE1931 system). We have loss in the &Eacute;tendue matched but that based on convention structure of projector. If we reduce the size of projector in the future, that defect will be reformed.
