Description

面板顯示裝置Panel display device

本發明係有關於一種面板顯示裝置,特別是一種框架分別由不同材料所製成之面板顯示裝置。The present invention relates to a panel display device, and more particularly to a panel display device in which frames are respectively made of different materials.

自液晶顯示器(Liquid Crystal Display)成為目前平面顯示器之主流後,其厚度之減少(薄型化)、整體重量之減輕(輕量化)以及整體製造成本之減低一直是製造廠商努力改進的問題,其中輕量化之目標主要係針對於使用元件數量的減少或是個別使用元件重量的減輕。一種可同時減輕使用元件重量及兼顧功能性之方法係為減少非功能性材料之使用。Since Liquid Crystal Display has become the mainstream of flat-panel displays, the reduction in thickness (thinning), the reduction in overall weight (lightweight), and the reduction in overall manufacturing costs have been problems that manufacturers have been trying to improve. The goal of quantification is primarily to reduce the number of components used or to reduce the weight of individual components. One method that can simultaneously reduce the weight of the components used and the functionality at the same time is to reduce the use of non-functional materials.

對於液晶顯示器來說,裝設於顯示面板之框架包含最多非功能性材料,也因此業界液晶顯示器之輕量化通常從顯示面板之框架用料之減少所開始。然而原本設置於框架上之鎖孔將因框架用料之減少而被取消,也因此液晶顯示器所包含元件之間的接合關係亦將受到影響。由此可見,輕量化之瓶頸係為如何在減少使用元件數量及減輕使用元件重量之同時,並兼顧顯示器成品或元件之功能。In the case of a liquid crystal display, the frame mounted on the display panel contains the most non-functional materials, and therefore the weight reduction of the liquid crystal display in the industry generally begins with the reduction of the frame material of the display panel. However, the keyhole originally provided on the frame will be eliminated due to the reduction of the frame material, and thus the joint relationship between the components included in the liquid crystal display will also be affected. It can be seen that the bottleneck of lightweighting is how to reduce the number of components used and reduce the weight of the components, while taking into account the functions of the finished products or components of the display.

此外,顯示面板之框架所使用的材料價格也將影響液晶顯示器之製造成本。而且不同製造材料亦具有其特有之防火係數、剛性及結構強度等特性。因此根據製造材料之特性及價格來有效率地製造框架,將是減少液晶顯示器製造成本之重要課題之一。In addition, the price of the materials used in the frame of the display panel will also affect the manufacturing cost of the liquid crystal display. Moreover, different manufacturing materials also have their unique characteristics of fire resistance, rigidity and structural strength. Therefore, efficient manufacturing of the frame according to the characteristics and price of the manufactured material will be one of the important issues for reducing the manufacturing cost of the liquid crystal display.

本發明目的之一為提供一種面板顯示裝置,因減少使用零件數量而具有較輕之整體重量。One of the objects of the present invention is to provide a panel display device having a lighter overall weight by reducing the number of parts used.

本發明之另一目的為提供一種面板顯示裝置,具有較低之整體厚度。Another object of the present invention is to provide a panel display device having a lower overall thickness.
