隨著液晶顯示器的發展，傳統的陰極射線管顯示器逐漸被液晶顯示器所取
代。近年來，消費者對於聲光效果的要求越來越高，液晶顯示器的解析度及電視尺寸等規格也隨著越來越高，再加上3C 產品朝向輕量與薄厚度的發展趨勢，面板本身的散熱空間受到限縮，同時提高解析度也使液晶顯示器驅動晶片的工作溫度跟著提高。在上述的二個因素之下，如何降低液晶顯示器驅動晶片的工作溫度是相當關鍵的一環。
目前降低液晶顯示器驅動晶片工作溫度的其中一項解決方案是在液晶顯
示器驅動晶片上貼一片鋁箔散熱片。本論文將評估其它高熱傳導係數材質的散熱片，例如銅箔及人造石墨的散熱效益，藉以取代鋁箔散熱片。實驗方面是將鋁箔、銅箔及人造石墨這三種材質各分成六種不同尺寸，以直流通電的方式使液晶顯示器驅動晶片溫度上升，再分別測量貼合前後的溫度差異以計算散熱效益。而此次實驗結果可以得到這三種材料的散熱效益的差異，同時也藉由EXCEL取得的回歸方程式，有助於未來在評估散熱片尺寸及選擇散熱材料時可以提供有效的參考。

With the development of liquid crystal displays, cathode ray tube displays are gradually being replaced by liquid crystal displays. In recent years, users have become more and more demanding of sound and light effects. The resolutions of LCD and TV sizes have also become higher and higher. In addition, 3C products are trending towards lighter weight and thinner thickness. The heat dissipation space is limited, and at the same time, increasing the
resolution also increases the operating temperature of the LCD driver IC. Under the two factors mentioned above, how to reduce the operating temperature of the LCD driver IC is a key factor.
One of the solutions to reduce the operating temperature of the LCD driver IC is to attach an aluminum foil heat sink on the LCD driver IC. This thesis will evaluate the heat release performance of other high heat conductivity materials such as copper foil and artificial graphite to replace aluminum foil heat sinks. In the experiment, three materials, aluminum foil, copper foil and artificial graphite, were divided into six different sizes, and the temperature of the LCD driver IC was raised by DC current. Then, the temperature difference before and after attachment was measured to calculate the heat release performance.
The results of this experiment can get the difference in heat release performance of these three materials. At the same time, the regression equation obtained by EXCEL can help to provide an effective reference when evaluating the size of the heat sink and selecting the material in the future.
