Description
本發明涉及一種顯示裝置,尤指一種允許外在物展示其中的顯示裝置。The present invention relates to a display device, and in particular, to a display device that allows external objects to be displayed therein.
查,顯示裝置領域以透明顯示結構實施者眾,如CN 105940441B、CN 103576357B、CN 106133587B、TW I610116及US 9753341B所揭,但現有顯示裝置普遍僅能單純提供透明顯示結構顯示功能,而未有可同時提供展示功能者。According to the investigation, there are many implementations of transparent display structures in the field of display devices, such as those disclosed in CN 105940441B, CN 103576357B, CN 106133587B, TW I610116 and US 9753341B. However, existing display devices generally can only provide transparent display structure display functions without any Those who also provide display functions.
目前顯示裝置普遍以層疊式結構實施,即背光模組、顯示結構與偏光結構之間為依序緊密設置,致使習用結構無法提供外在物設置,亦無法提供展示功能。當習用顯示裝置供外在物設置其中時,將拉長背光模組與顯示結構之間的距離,致使習用顯示裝置的光線穿透率不足,而無法明顯的展示出外在物。此外,現有顯示裝置搭配鏡面效果實施者,顯示裝置受限於高亮度與高穿透率,使得鏡面效果受打折;反之,如為維持鏡面效果,則影響顯示裝置的亮度。At present, display devices are generally implemented in a stacked structure, that is, the backlight module, display structure and polarizing structure are closely arranged in sequence. As a result, the conventional structure cannot provide external object settings and cannot provide display functions. When external objects are placed in a conventional display device, the distance between the backlight module and the display structure will be lengthened, resulting in insufficient light transmittance of the conventional display device and the inability to clearly display the external objects. In addition, for existing display devices equipped with mirror effects, the display devices are limited by high brightness and high transmittance, which compromises the mirror effect; conversely, maintaining the mirror effect affects the brightness of the display device.
US 2013107160A雖公開提供外在物設置其中,並可作為外在物展示器的技術,惟US 2013107160A為避免前述光線穿透率不足的缺陷,同時亦為避免背光模組投射的光線被外在物遮蔽的問題,因此US 2013107160A需額外對外在物設置光源。另外,US 2013107160A未公開顯示裝置存在鏡面效果,或是提出改善顯示裝置無法提升穿透率並保留鏡面效果的問題。Although US 2013107160A discloses the technology of placing external objects in it and using it as a display device for external objects, US 2013107160A avoids the aforementioned defect of insufficient light transmittance and also prevents the light projected by the backlight module from being blocked by external objects. There is a problem of shielding, so US 2013107160A requires an additional light source for external objects. In addition, US 2013107160A does not disclose that the display device has a mirror effect, or raises the issue that improving the display device cannot increase the transmittance and retain the mirror effect.
本發明的主要目的,在於解決習用顯示裝置如提供外在物設置時,將降低光線穿透率的問題。The main purpose of the present invention is to solve the problem that conventional display devices will reduce the light transmittance when provided with external objects.
本發明的另一目的,在於解決習用顯示裝置無法提升穿透率並保留鏡面效果。Another object of the present invention is to solve the problem that conventional display devices cannot improve the transmittance and retain the mirror effect.
為達上述目的,本發明提供本發明提供一種允許外在物展示其中的顯示裝置,包含一成形有一空間的本體,一設於該空間的背光模組,及一設於該空間的顯示模組,該背光模組具有一投光面,該顯示模組與該背光模組以一間距分離設置,該間距的長度足令至少一外在物位在其中,該顯示模組包含一透明顯示結構,一設於該透明顯示結構面向該投光面一側的第一光學膜,以及一設於該透明顯示結構遠離該投光面一側的第二光學膜,該第一光學膜允許該背光模組直接投射的光線及被該本體反射的光線通過,該第二光學膜允許來自該透明顯示結構的光線通過,並反射該本體外的一環境光。To achieve the above object, the present invention provides a display device that allows external objects to be displayed, including a body formed with a space, a backlight module disposed in the space, and a display module disposed in the space. , the backlight module has a light projection surface, the display module and the backlight module are separated by a distance, the distance is long enough to allow at least one external object level to be located therein, the display module includes a transparent display structure , a first optical film provided on the side of the transparent display structure facing the light projection surface, and a second optical film provided on the side of the transparent display structure away from the light projection surface, the first optical film allows the backlight The light directly projected by the module and the light reflected by the body pass through. The second optical film allows the light from the transparent display structure to pass through and reflects an ambient light outside the body.

本發明詳細說明及技術內容,茲配合圖式說明如下:The detailed description and technical content of the present invention are described as follows with reference to the drawings:
請參閱圖1至圖5,本發明提供一種顯示裝置100,該顯示裝置100允許至少一外在物200展示其中,並可提升穿透率與反射率。該顯示裝置100包含一本體10,一背光模組20,及一顯示模組30,該本體10作為該顯示裝置100的外殼,並成形一空間11,該空間11提供該背光模組20與該顯示模組30設置其中。該背光模組20具有一投光面21,該投光面21於該背光模組20啟動時可向外投射一背光光線22,該顯示模組30位於該背光模組20一側,且與該背光模組20以一間距31分離設置。其中,本文所述的分離設置,非為該顯示裝置100於結構分解時所產生的距離,而是該顯示模組30不與該背光模組20緊鄰設置,當該顯示裝置100組裝完成時,該顯示模組30即與該背光模組20存在該間距31。Referring to FIGS. 1 to 5 , the present invention provides a
承上,該顯示裝置100為提供展示功能,該間距31被設計用以提供該外在物200設置,該間距31的長度需足令該外在物200位在其中,即該間距31的長度必須是大於或是等於該外在物200的長度,以容納該外在物200。又,該顯示模組30包含一透明顯示結構32,一第一光學膜33及一第二光學膜34,該透明顯示結構32決定該顯示模組30的工作,該透明顯示結構32可基於導電狀態改變光線的偏振方向。以該透明顯示結構32採液晶顯示舉例說明,該透明顯示結構32包含二間隔設置的透明電極,以及一位於該二透明電極之間的液晶分子層,該液晶分子層內含複數液晶分子,該些液晶分子於該二透明電極導通時,該些液晶分子受外加電場影響,改變原本的排列方式,並進而改變光線的偏振方向。反之,該二透明電極停止被導通時,該些液晶分子恢復原本的排列方式,而無法改變光線的偏振方向。需了解到,本發明該透明顯示結構32不以前述實施例為限制,舉凡可決定該顯示裝置100的工作狀態者均應屬本發明範疇。In order to provide the display function, the
承上,該第一光學膜33位於該顯示模組30面向該投光面21的一側,該第一光學膜33提供偏振功能。更詳細地,該第一光學膜33接受由該背光模組20而來的該背光光線22,並具有一第一偏光軸332,該第一光學膜33接受該背光光線22中偏振方向與該第一偏光軸332相同者(如標號221)通過,並拒絕該背光光線22中偏振方向與該第一偏光軸332不同者通過(如標號222)。舉例來說,假設該第一偏光軸332為垂直向時,該背光光線22中垂直偏振方向者可通過該第一光學膜33,該背光光線22中其餘偏振方向者則未能通過該第一光學膜33。此外,該第一光學膜33亦接受被該本體10反射的一反射光線12,該反射光線12可以是由該背光光線22轉變而成,當該背光光線22朝該顯示模組30方向行進時,該背光光線22的部分可能被該第一光學膜33阻擋而反射,也可能被該外在物200反射,該背光光線22中被反射者反射至該本體10上並被打散,當該背光光線22中被反射者再次成為非偏振光,且再次被該本體10反射時,該背光光線22即轉變為該反射光線12。由前述可知,該反射光線12中偏振方向與該第一光學膜33相同者(如標號121)可穿透該第一光學膜33,其餘者則無法,該反射光線12中未能穿透該第一光學膜33者將再次反射至該本體10,並於被打散後再次被反射至該第一光學膜33,以此循環。承此,本發明該第一光學膜33除了單純接受由該背光模組20而來的該背光光線22外,更回收該背光光線22中未能穿透該第一光學膜33者(如標號222)與該背光光線22中被該外在物200反射者,以此提升該背光模組20的出光效率,達到增亮效果。Following the above, the first
而該第二光學膜34位於該顯示模組30遠離該投光面21一側,該第二光學膜34與該第一光學膜33相對,該第二光學膜34亦提供偏振功能。具體來說,該第二光學膜34接受由該顯示模組30而來的光線通過,此光線可以是基於該顯示模組30自身所產生,也可以是該顯示模組30接受來自於該第一光學膜33的一偏振光線331轉變而成。須注意的是,本發明所述該偏振光線331指的是由該第一光學膜33而來的光線,包含該背光光線22中偏振方向與該第一偏光軸332相同者(如標號221),以及該反射光線12中偏振方向與該第一光學膜33相同者(如標號121)的至少其一。一實施例中,該第二光學膜34具有一與該第一偏光軸332垂直的第二偏光軸341,當該顯示模組30的光線是由該偏振光線331轉變而成時,該第二光學膜34在該顯示模組30未通電前,阻止由該第一光學膜33而來的該偏振光線331通過,而當該顯示模組30通電時,由於該偏振光線331的偏振方向被改變,使得該偏振光線331得以穿透該第二光學膜34。又,該第二光學膜34於接受該本體10外的一環境光400後,該第二光學膜34更可反射該本體10的該環境光400,藉此令該顯示裝置100產生鏡面效果。於一實施例中,該第二光學膜34的光線穿透率為80%,環境光反射率至少60%。The second
承上,現就該顯示裝置100的實施進行說明。假設初始時該背光模組20產生該背光光線22,但該透明顯示結構32未通電,此時該背光光線22朝該顯示模組30方向行進,該背光光線22的部分被該外在物200阻擋,進而反射至該本體10,而該背光光線22的其餘部分未被該外在物200阻擋,直接朝該第一光學膜33方向行進。該第一光學膜33接受該背光光線22中偏振方向與該第一偏光軸332相同者(如標號221),及該反射光線12中偏振方向與該第一偏光軸332相同者(如標號121)通過,並令該背光光線22中偏振方向與該第一偏光軸332相同者(如標號221),及該反射光線12中偏振方向與該第一偏光軸332相同者(如標號121)轉變為該偏振光線331。於此當下,由於該透明顯示結構32未通電,該偏振光線331未能改變偏振方向,而無法通過該第二光學膜34,使得該顯示裝置100呈現黑屏,而無法展示出該外在物200。於同一時間,該第二光學膜34於該顯示裝置100呈黑屏時,該第二光學膜34仍可反射該環境光400,並維持至少60%的反射率,就如圖5所示。其中,圖5所繪在於描述該顯示裝置100於未通電時的鏡面功能,即此圖中的人像為使用者於該顯示裝置100上顯示的鏡面成像。Following the above, the implementation of the
承上,一旦該透明顯示結構32通電後,該偏振光線331的偏振方向得以被改變,並得以通過該第二光學膜34,使該顯示裝置100呈現亮屏,並可展示出該外在物200,就如圖4所繪。其中,圖4的該顯示裝置100可展示出該外在物200,並以太陽圖像與方塊圖案等表示該透明顯示結構32顯示的資訊。須了解到,本文圖4雖未繪示該顯示裝置100的鏡面功能,但該顯示裝置100於通電後,該第二光學膜34亦維持反射該環境光400的功能,並提供該顯示裝置100鏡面效果。Following the above, once the
由上述可知,本發明該顯示裝置100不以緊密層疊結構實施,該顯示模組30與該背光模組20之間存在該間距31,以令該外在物200得以設置其中。同時,本發明該第一光學膜33可允許該背光模組20直接投射的光線通過外,更可回收被反射的光線,藉此達到增亮效果,而該第二光學膜34更具備反射該環境光400的功能,藉此令本發明產生鏡面效果。本發明改善習用顯示裝置在提升穿透率時必須犧牲反射率,或是增加反射率時必須降低穿透率的問題。From the above, it can be seen that the
承上,請參閱圖6與圖7,一實施例中,該本體10具有複數內壁13,該些內壁13與該顯示模組30共同界定出該空間11,該些內壁13為達到反射效果,該些內壁13至少其中之一亦可設有一反射層131,該反射層131反射由該外在物200或該第一光學膜33而來的光線,舉例來說,該反射層131可以是白漆塗層或是鏡面塗層。除前述之外,本發明更可以於該些內壁13均設有該反射層131,藉此以提升該本體10的反射能力。再者,本發明為避免該背光光線22無法具體提供該外在物200展示照明,該背光模組20與該顯示模組30之間的該間距31小於等於35公分。Continuing with the above, please refer to Figures 6 and 7. In one embodiment, the
再另一方面,請參閱圖8,一實施例中,該顯示裝置100更可具有觸控功能,該顯示模組30包含一觸控面板40,該觸控面板40設於該顯示模組30遠離該背光模組20一側,該觸控面板40可以是基於量子穿隧、電容、電阻等方式提供觸控,透過使用者點觸該觸控面板40,而產生訊號上變化,藉此達到控制目的。進一步地,於本實施例中,該第二光學膜34被設於該透明顯示結構32與該觸控面板40之間。On the other hand, please refer to FIG. 8 . In one embodiment, the
綜上述僅為本發明的一較佳實施例而已,當不能以此限定本發明實施範圍,即凡依本發明申請專利範圍所作的均等變化與修飾,皆應仍屬本發明專利涵蓋範圍。In summary, the above is only a preferred embodiment of the present invention, and it should not be used to limit the scope of the present invention. That is, all equivalent changes and modifications made based on the patent scope of the present invention should still fall within the scope of the patent of the present invention.
