Description
本揭露實施例是有關於一種顯示裝置,且特別是有關於一種具有整合式膠框的顯示裝置。
光學膠,例如光學透明樹脂(optical clear resin,OCR),是設計用於透明光學元件黏結的特種黏結劑。光學膠可填充面板與透明蓋板之間的空隙,以提高顯示器的對比。與傳統採用空氣間隙的方法相比,光學膠可抑制外部光照與背光等導致的光散射情況,並適用於觸控螢幕、大尺寸玻璃基板或其它軟硬板之間的貼合與組裝。
在習知顯示裝置的灌膠操作中,需要設置外掛式框件作為灌膠用的框體,然後才能將光學膠(例如光學透明樹脂)注入外掛式框件與蓋板所形成的空間內。然而,習知的外掛式框件有其應用上的限制,例如無法應用於不含前鐵框的液晶面板(open cell),因為此種液晶面板無前鐵框可黏貼外掛式框件,其本身全周亦無足夠空間黏貼外掛式框件。此外,外掛式框件的材料需求以及它與液晶顯示模組(liquid crystal display module,LCM)的組裝程序亦是液晶顯示裝置之製程的負擔。
本揭露之目的在於提出一種顯示裝置,藉由將灌膠用框體與背光模組之膠框整合為整合式膠框,而能簡化製程並提升產品競爭力。
根據本揭露之上述目的,提出一種顯示裝置包含面板、背光模組、蓋板、整合式膠框以及光學膠。面板設於背光模組之上。蓋板設於面板之上,且面板位於蓋板與背光模組之間。整合式膠框包含第一容置部、第二容置部及膠體限制部。第二容置部接合於第一容置部與膠體限制部之間,且第一容置部、第二容置部與膠體限制部之組合呈一體成型結構。第一容置部係容置背光模組之至少一部分,第二容置部係容置面板,膠體限制部係接合於第二容置部與蓋板之間,而與蓋板及面板共同定義出容置空間。光學膠設置於容置空間內。
在一些實施例中,面板包含顯示面板、觸控顯示面板、或觸控面板與顯示面板相互貼合。
在一些實施例中,蓋板為平板結構或曲形板結構。
在一些實施例中,膠體限制部為環形結構。
在一些實施例中,蓋板鄰近膠體限制部之一側具有第一斜面,且膠體限制部鄰近蓋板之一側具有第二斜面,其中第一斜面與第二斜面之形狀彼此匹配。
在一些實施例中,蓋板與膠體限制部之間設有連結元件連結蓋板與膠體限制部。
在一些實施例中,面板與第二容置部之間設有連結元件連結面板與第二容置部。
在一些實施例中,膠體限制部具有至少一肋條補強結構,肋條補強結構位於膠體限制部之內側並接觸光學膠。
在一些實施例中,膠體限制部具有至少一肋條補強結構,肋條補強結構位於膠體限制部之外側。
綜上所述,本揭露實施例之顯示裝置藉由將灌膠用框件的3D特徵整合至背光模組之膠框而成為整合式膠框,因而能藉由單一膠框同時達到灌膠用框件與背光模組膠框的功能,即容置背光模組、容置面板並且與蓋板連結而形成光學膠的容置空間。因此,本揭露實施例之顯示裝置可減少灌膠用框件之材料需求,並可減少一道灌膠用框件與液晶顯示模組的接合程序。此外,本揭露實施例之整合式膠框更可應用於無前鐵框之顯示面板。因此,本揭露實施例之顯示裝置能簡化製程並提升產品競爭力。
為讓本揭露的上述特徵和優點能更明顯易懂,下文特舉實施例,並配合所附圖式作詳細說明如下。
以下仔細討論本揭露的實施例。然而,可以理解的是,實施例提供許多可應用的概念,其可實施於各式各樣的特定內容中。所討論與揭示的實施例僅供說明,並非用以限定本揭露之範圍。本揭露的所有實施例揭露多種不同特徵,但這些特徵可依需求而單獨實施或結合實施。另外,關於本文中所使用之「第一」、「第二」、…等,並非特別指次序或順位的意思,其僅為了區別以相同技術用語描述的元件或操作。此外,本揭露所敘述之二元件之間的空間關係不僅適用於圖式所繪示之方位,亦適用於圖式所未呈現之方位,例如倒置之方位。此外,本揭露所稱二個部件的「連接」、「耦接」、「電性連接」或之類用語並非僅限制於此二者為直接的連接、耦接、或電性連接,亦可視需求而包含間接的連接、耦接、或電性連接。
圖1為本揭露實施例之一種顯示裝置1的剖面側視示意圖。本揭露實施例不限制顯示裝置1之種類,顯示裝置1可為平面顯示裝置或曲面顯示裝置,或者為2D顯示裝置或3D顯示裝置等。
如圖1所示,顯示裝置1包含面板11、背光模組12、蓋板13、整合式膠框14以及光學膠15。面板11設於背光模組12之上。面板11例如但不限於液晶顯示面板,本實施例之面板11以包含無前鐵框的顯示面板為例。在其他實施例中,面板11的構造可依需求而調整,例如面板11可包含顯示面板、或觸控顯示面板、或觸控面板(膜)與顯示面板相互貼合之面板。上述之觸控顯示面板是指顯示面板具有觸控結構。
背光模組12可為直下式或側光式背光模組,於此是以側光式背光模組為例。在本實施例中,背光模組12例如包含光源121、導光板122、反射片123及光學膜組124。光源121鄰設於導光板122之一側面,以從導光板122之側面朝導光板122發射光線。光源121可為點光源、線光源或面光源。舉例而言,光源121可包含發光二極體或其他電致發光(electroluminescence,EL)元件。反射片123設置於導光板122之底部,以將射向導光板122之底部的光線反射至光學膜組124。光學膜組124位於導光板122之上並位於導光板122與面板11之間,並可改善光線的光學性質或使光線的光學性質符合需求。光學膜組124可例如包含擴散膜、增亮膜、微透鏡光學膜等。透過光學膜組124的光線進入面板11而形成影像。上述背光模組12所包含的部件僅為舉例說明,在其他實施例中可依需求而增設、替換或省略部件。
蓋板13設於面板11之上,且面板11位於蓋板13與背光模組12之間。蓋板13可保護面板11,使其不受外界環境汙染與外力衝擊。光學膠15可填充於蓋板13與面板11之間的空間,以提升顯示裝置1的光學性質。光學膠15可例如為光學透明樹脂。蓋板13可為平板結構或曲形板結構,於此是以曲形板結構為例。
本揭露實施例之整合式膠框14具有第一容置部141、第二容置部142及膠體限制部143,其中第二容置部142接合於第一容置部141與膠體限制部143之間,且第一容置部141、第二容置部142與膠體限制部143之組合呈一體成型結構。第一容置部141係容置背光模組12之至少一部分,於此係以至少容置導光板122、反射片123及光學膜組124為例。第二容置部142係容置面板11。在本實施例中,整合式膠框14可例如具有階梯結構,以利第一容置部141與第二容置部142分別承載背光模組12與面板11。膠體限制部143係接合於第二容置部142與蓋板13之間,而與蓋板13及面板11共同定義出容置空間17。光學膠15設置於容置空間17內。膠體限制部143為環形結構,以與蓋板13及面板11共同形成密閉的容置空間17。
膠體限制部143與蓋板13可有多種連接方式。以直接連接來說,膠體限制部143與蓋板13可相互卡設而連接;以間接連接來說,可藉由連結元件連接於膠體限制部143與蓋板13之間,連接元件可為雙面膠或卡設結構。在本實施例中,蓋板13鄰近膠體限制部143之一側具有第一斜面13a,且膠體限制部143鄰近蓋板13之一側具有第二斜面143a,其中第一斜面13a與第二斜面143a之形狀彼此匹配,例如形狀互補。由於第一斜面13a與第二斜面143a之形狀彼此匹配,因此第一斜面13a與第二斜面143a可對應接合,有利於膠體限制部143與蓋板13之間的連接。
另外,顯示裝置1可更包含背板16,背板16與整合式膠框14連接。在本實施例中,光源121(包含發光元件及電路板)可設置於背板16上並固定於背板16。另外,背板16抵靠並固定反射片123。
圖2為本揭露實施例之另一顯示裝置2的示意圖。如圖2所示,顯示裝置2包含面板21、背光模組22、蓋板23、整合式膠框24以及光學膠25。整合式膠框24包含第一容置部241、第二容置部242及膠體限制部243。光學膠25設置於膠體限制部243、蓋板23與面板21所形成之容置空間內。上述構件之技術特徵可參照圖1所示之實施例,於此不再贅述。
另外,在本實施例中,面板21與第二容置部242之間設有連結元件C1連結面板21與整合式膠框24,其中連結元件C1可例如為雙面膠。此外,蓋板23與膠體限制部243之間設有連結元件C2連結該蓋板23與整合式膠框24,其中連結元件C2可例如為雙面膠。在本實施例中,膠體限制部243鄰近蓋板23之一側為平面,且連結元件C2之形狀例如為楔形,以便於連接蓋板23與整合式膠框24之膠體限制部243,亦即連結元件C2鄰近膠體限制部243之一側為平面,而鄰近蓋板23之一側為斜面。
圖3為本揭露實施例之整合式膠框之膠體限制部343的示意圖,膠體限制部343可包含圖1之膠體限制部143及/或圖2之膠體限制部243的技術特徵。如圖3所示,膠體限制部343靠近蓋板之一側具有多個3D特徵以匹配蓋板之形狀而能達到二者之較為緊密的連接,3D特徵例如包含平面部343a、凹陷部343b及/或凸起部343c。另外,膠體限制部343可更具有至少一肋條補強結構343d,肋條補強結構343d可位於膠體限制部343之內側或外側,於此是以位於外側為例。在本實施例中,肋條補強結構343d係以位於凸起部343c為例。肋條補強結構343d可增強整體的結構強度。
圖4為本揭露實施例之另一肋條補強結構443d的示意圖,如圖4所示,肋條補強結構443d位於整合式膠框44之膠體限制部443之內側,並因此接觸光學膠45。肋條補強結構443d除了增強整體結構強度之外,光學膠45流入肋條補強結構443d中,可增加光學膠45與膠體限制部443之間的接觸面積,藉此可增加光學膠45與膠體限制部443之間的連結強度,進一步增加整體的結構強度,更可降低光學膠45與膠體限制部443之間剝離的可能性。注入的光學膠45可能會產生氣泡B,當產生氣泡B時,氣泡B會躲藏於肋條補強結構443d中,因而可避免影響顯示裝置的顯示效果。氣泡B可包含灌膠氣泡及/或環側氣泡。
由以上說明可知,本揭露實施例之顯示裝置藉由將灌膠用框件的3D特徵整合至背光模組之膠框而成為整合式膠框,因而能藉由單一膠框同時達到灌膠用框件與背光模組膠框的功能,即容置背光模組、容置面板並且與蓋板連結而形成光學膠的容置空間。因此,本揭露實施例之顯示裝置可減少灌膠用框件之材料需求,並可減少一道灌膠用框件與液晶顯示模組的接合程序。此外,本揭露實施例之整合式膠框更可應用於無前鐵框之顯示面板。因此,本揭露實施例之顯示裝置能簡化製程並提升產品競爭力。
以上概述了數個實施例的特徵,因此熟習此技藝者可以更了解本揭露的態樣。熟習此技藝者應了解到,其可輕易地把本揭露當作基礎來設計或修改其他的製程與結構,藉此實現和在此所介紹的這些實施例相同的目標及/或達到相同的優點。熟習此技藝者也應可明白,這些等效的建構並未脫離本揭露的精神與範圍,並且他們可以在不脫離本揭露精神與範圍的前提下做各種的改變、替換與變動。
