1. Hsu, Wei-Tsung. A New Design of Light Guide Plate on the Elimination of Dark Region Phenomenon for Backlight Module.

Degree: Master, Mechanical and Electro-Mechanical Engineering, 2008, NSYSU

Liquid crystal display (LCD) has been widely used as an important human interface with typical portable devices such as notebook-type computers, digital camera and cell phones, etc. The LCD panel does not emit light spontaneously, and thus it needs a surface backlight source. The function of light guide plate (LGP) was to guide light from a light source and radiates it homogeneously from all over its output surface. In this thesis, the research object was focused on this optical component. This thesis mainly concludes two major parts. The first part focused on the design of cold fluorescent lamp (CCFL) light source LGP. If the bottom structure of the LGP in a backlight module was made up of V-Cut micro-structures, then conventionally, the shape and spacing between any two adjacent columns of micro-structure should be designed specifically in order to obtain a more uniform illuminance distribution. It was required to apply complicated mathematics and cost a lot of time to design. In this study, a simplified bottom structure of the LGP was proposed. The considered bottom structure of the LGP was proposed to be made up of same shape high energy V-Cut micro-structures, and the spacing between any two adjacent columns of the micro-structure was also the same. The design parameters were determined by using optimization technique. Also, the LCD design time could be reduced. In order to eliminate the dark region phenomenon caused by the proposed simplified bottom structure of the LGP, a simple new type of edge structure of the LGP was proposed also. The proposed simplified LGP design concepy has many merits, such as only three design parameters needed, manufacturing easily, the design time can be reduced, and can prevent the consumption of light source energy between the gaps of CCFL and LGP. The proposed design concept was applied on the design of 7 inches, 15 inches and 20 inches of backlight module (BLM). Through the numerical simulation by utilizing commercial software Light Tools, it can be shown that more than 80% of uniformity can be easily obtained. The second part focused on traditional dot pattern bottom structures. As the same concept mentioned in the first part, the proposed dot pattern was made up of same geometrival shape of dots, and the spacing between any two adjacent columns of the dots was also the same. The design parameters were determined by using optimization technique. The proposed design concept of the dot patten distribution can be applied on the design of LGP with either LED or CCFL light source. Also, the dark phenomenon did not occur, and so the corresponding edge structure did not need either. The proposed design concept was applied on the design of 7 inches, 15 inches and 20 inches of BLM with CCFL light source and on the design of 7 inches of BLM with LED light sources. The optical simulation results showed that about 90% of uniformity can be easily obtained.

2. Tasi, Yao-Wei. The Structural Design of The Prism Sheet in LCD Back Light Module.

Degree: Master, Mechanical and Electro-Mechanical Engineering, 2005, NSYSU

The manufacturing technology of LCD is becoming skillful gradually and begins to popularize in recent years, and its relevant component is developed vigorously accordingly. In the numerous key components of LCD, back light module(BLM) is easiest to make, but its cost accounted is very high in specific gravity, so it attracts large quantities of manufacturers to plunge into the relevant studies. However, so far, most of studies concentrate on the light guide plate and the diffuser sheet, there are seldom researches corresponding to the brightness enhancement of the back light module while is relating to the prism sheet(brightness enhancement film, BEF). Therefore, this thesis will focus on the constructing of the optical module of the prism sheet and the effects of the prism sheetâs structure parameter on the brightness enhancement. By utilizing optics simulation software ASAP to build and construct out the prism sheet optics module, one can analyze and discuss the effect of the variation of its structure parameter, such as prismatic degree(θ), prismatic structure(t), polyester substrate(T) and the refract rate of bottom sill on the brightness enhancement. It can be found from the result of simulation, relative to other structure parameter, the changing of the prismatic degree(θ) influence the brightness enhancement the most, and have the best result on 104 degree.

3. Li, Yi-Feng. Stress Analysis of Specimen and Machine of Friction Stir Welding.

Degree: Master, Mechanical and Electro-Mechanical Engineering, 2005, NSYSU

FSW is a new welding technology developed in 1991, but up till now, the study on FSW is mainly focus on the residual stress, micro-structure and thermal effect of specimen etc. However, the stresses of the machine platform have not discussed yet. This research of the stresses of the machine, and the results can be used to design the machine platform of the FSW for micro specimen in the future. The governing equilibrium equation of machine platform under the load was set up in the beginning. Then the equation was solved by using the MATLAB software. The main influence ranges of deflections of the specimen and of the machine platform was obtained and discussed.
