Description
本發明係提供一種顯示器,尤指一種不需縮減框體尺寸便能具有寬闊可視區的顯示器。 The present invention provides a display, and more particularly a display having a wide viewing area without reducing the size of the frame.
顯示設備(例如電腦螢幕與手機螢幕)具有超薄邊框的外觀特徵是提高消費者購買慾望的因素之一。顯示影像佔顯示設備之表面積的比例越大,邊框佔顯示設備之表面積的比例會相應縮小。雖然超薄邊框的顯示器具有較佳市場競爭力,但是顯示設備的顯示區範圍相當於顯示模組之光學元件(例如偏光片)的大小,框體的尺寸則取決於結構設計、產品組裝和安全強度等因素難以無限制地縮小收窄,故如何克服框體的尺寸侷限,設計出更窄邊框或無邊框的顯示設備便為相關機構產業的重要發展目標。 The appearance of display devices (such as computer screens and mobile screens) with ultra-thin bezels is one of the factors that increase consumer desire to buy. The greater the ratio of the displayed image to the surface area of the display device, the smaller the ratio of the border to the surface area of the display device. Although the display of the ultra-thin bezel has better market competitiveness, the display area of the display device is equivalent to the size of the optical components (such as polarizers) of the display module, and the size of the frame depends on the structural design, product assembly and safety. Factors such as strength are difficult to narrow and narrow indefinitely. Therefore, how to overcome the size limitation of the frame and design a display device with a narrower border or no border is an important development goal of the relevant institution industry.
本發明係提供一種不需縮減框體尺寸便能具有寬闊可視區的顯示器,以解決上述之問題。 The present invention provides a display having a wide viewing area without reducing the size of the frame to solve the above problems.
本發明之申請專利範圍係揭露一種具有寬闊可視區的顯示器,其包含有一框體、一顯示模組以及一面板模組。該顯示模組設置在該框體內,該面板模組設置在該框體上且覆蓋該顯示模組。該面板模組具有一可視區與該顯示模組重疊。該面板模組包含一透光玻璃、一承載薄膜以及一微透鏡組合。該承載薄膜設置在該透光玻璃與該顯示模組之間。該微透鏡組合位於該 可視區內,且設置在該顯示模組與該透光玻璃間。該微透鏡組合具有發散光線的光學特性。 The patent application scope of the present invention discloses a display having a wide viewing area, which comprises a frame body, a display module and a panel module. The display module is disposed in the frame, and the panel module is disposed on the frame and covers the display module. The panel module has a visible area overlapping the display module. The panel module comprises a light transmissive glass, a carrier film and a microlens combination. The carrier film is disposed between the light transmissive glass and the display module. The microlens combination is located at the In the visible area, and disposed between the display module and the transparent glass. The microlens assembly has optical properties of divergent light.
本發明的顯示器不必改變框體尺寸,而是利用設置在顯示模組與透光玻璃之間的微透鏡組合去折射光線,藉此將顯示模組輸出的影像放大到可視區的範圍,提供窄邊框的視覺效果。微透鏡組合可設置在承載薄膜或透光玻璃上,依其設置位置及透鏡單元的指向變化可相應包含多個平凸透鏡單元或平凹透鏡單元。微透鏡組合之作用在於匯聚來自顯示模組的影像光線,進而將影像光線發散以將其經由透光玻璃射出,讓面板模組能夠具有將顯示區之影像放大為可視區之尺寸的視覺效果。 The display of the present invention does not need to change the size of the frame, but uses a combination of microlenses disposed between the display module and the light transmissive glass to refract light, thereby magnifying the image output by the display module to a range of the visible area, providing a narrow The visual effect of the border. The microlens assembly may be disposed on the carrier film or the light transmissive glass, and may include a plurality of plano-convex lens units or plano-concave lens units according to the position of the lens and the change in the orientation of the lens unit. The purpose of the microlens assembly is to converge the image light from the display module, thereby diverging the image light to emit it through the light transmissive glass, so that the panel module can have the visual effect of enlarging the image of the display area to the size of the visible area.
微透鏡組合係由透明材質組成,例如氧化銦錫(Indium tin oxide,ITO)或其它透明材料,以印刷、壓印或蝕刻方式直接形成或貼合在承載薄膜或透光玻璃,故使用微透鏡組合產生放大影像不會增加顯示器的組裝步驟。相較先前技術,本發明的顯示器具有體積輕巧和組裝容易的優點,能形成寬闊可視區而造成窄邊框的視覺效果,不需物理性地收窄邊框尺寸去破壞顯示器的結構強度。 The microlens assembly is composed of a transparent material, such as indium tin oxide (ITO) or other transparent material, which is directly formed or bonded to the carrier film or the light transmissive glass by printing, imprinting or etching, so the microlens is used. Combining to produce an enlarged image does not increase the assembly steps of the display. Compared with the prior art, the display of the present invention has the advantages of compact size and easy assembly, can form a wide viewing area and cause a visual effect of a narrow bezel, and does not need to physically narrow the frame size to damage the structural strength of the display.

The panel module 16 has a light transmissive glass 20, a carrier film 22, and a microlens assembly 24. The microlens assembly 24 is capable of magnifying the image of the display area Rd to conform to the size of the viewable area Rv of the panel module 16. The display area Rd has the same range as the display module 14, and the visible area Rv is larger than the display area Rd to overlap the frame 12. Therefore, the display 10 can still have a thin border without changing the size of the frame 12. Visual effects.
承載薄膜22與微透鏡組合24皆設置在透光玻璃20與顯示模組14之間。承載薄膜22通常利用光學膠貼合於透光玻璃20。微透鏡組合24位於可視區Rv內,並具有發散光線的光學特性。承載薄膜22和微透鏡組合24的相對位置及微透鏡組合24的光學元件可根據不同實施態樣而有對應變化。舉例來說,微透鏡組合24由平凹透鏡單元組成時,其係設置在承載薄膜22且面向顯示模組14、或設置在透光玻璃20且面向承載薄膜22;微透鏡組合24由平凸透鏡組成時,則是設置在承載薄膜22且面向透光玻璃20,然不限於此。 Both the carrier film 22 and the microlens assembly 24 are disposed between the light transmissive glass 20 and the display module 14. The carrier film 22 is typically bonded to the light transmissive glass 20 using an optical adhesive. The microlens assembly 24 is located within the viewing zone Rv and has the optical properties of diverging light. The relative positions of the carrier film 22 and the microlens assembly 24 and the optical elements of the microlens assembly 24 may vary correspondingly depending on the implementation. For example, when the microlens assembly 24 is composed of a plano-concave lens unit, it is disposed on the carrier film 22 and faces the display module 14, or is disposed on the light transmissive glass 20 and faces the carrier film 22; the microlens assembly 24 is composed of a plano-convex lens.

The sub-display area R2 may have a frame shape and is disposed around the periphery of the main display area R1, that is, the position of the sub-display area R2 is between the main display area R1 and the frame 12. The microlens assembly 24 is preferably disposed in the sub display region R2 for refracting light passing through the boundary of the display region Rd (for example, the sub display region R2) to display the display region Rd. The image is enlarged to the extent of the visible area Rv. However, the arrangement area of the microlens assembly 24 is not limited to the foregoing embodiment, and for example, a part of the microlens assembly 24 can also be disposed in the main display area R1. Any technique that can refract light through a combination of microlenses to magnify an image belongs to the design of the present invention, and therefore, other embodiments will not be separately illustrated.
