Abstract
Description
本發明涉及觸控顯示領域,尤其涉及一種顯示裝置及一種觸控顯示裝置。 The present invention relates to the field of touch display, in particular to a display device and a touch display device.
全貼合(Direct Bonding)是對一種貼合工藝的簡稱,是將觸控面板與顯示面板(通常為液晶顯示面板)直接貼合在一起,最終形成觸控顯示模組的過程。採用上述全貼合方式相較於採用傳統的框貼(Air Bond)方式使得觸控顯示模組的結構具有更良好的光學特性,畫面清晰。習知之車載式的顯示模組通常具有一外保護框,該外保護框導致對貼合時的膠體有特定的尺寸要求,故在採用全貼合方式時,常利用液態光學膠實現貼合,然,液態光學膠的注入量不易控制,注入液態膠過量時,一方面其從注入口溢出需要進行清理,另一方面不利於氣泡的排出。 Direct bonding is an abbreviation for a bonding process, which is a process of directly bonding a touch panel and a display panel (usually a liquid crystal display panel) together to form a touch display module. Compared with the traditional air bond method, the above-mentioned full bonding method enables the structure of the touch display module to have better optical characteristics and a clear picture. Conventional vehicle-mounted display modules usually have an outer protective frame. The outer protective frame causes specific size requirements for the glue when bonding. Therefore, when the full bonding method is adopted, liquid optical glue is often used to achieve bonding. However, the injection amount of the liquid optical glue is not easy to control. When the liquid glue is injected excessively, on the one hand, it overflows from the injection port and needs to be cleaned, on the other hand, it is not conducive to the discharge of bubbles.

本實施例提供的顯示裝置,適用於車載的小屏幕顯示裝置。請參閱圖1,本實施例提供的顯示裝置10,顯示模組12以及層疊在顯示模組12上的蓋板11。蓋板11上遠離顯示模組12的表面111作為顯示面,用戶借由該表面111觀看顯示模組12顯示的圖像。本實施例中,顯示模組12為液晶顯示模組,於其他實施例中,顯示模組12亦可為自發光顯示模組或有機發光顯示模組等,本發明不對此作限制。
The display device provided in this embodiment is suitable for a small screen display device in a vehicle. Please refer to FIG. 1, the
請參閱圖2,本實施例提供的顯示裝置10還包括第一貼合部13及第二貼合部14。第一貼合部13與第二貼合部14皆位於蓋板11與顯示模組12之間,用於貼合蓋板11與顯示模組12。顯示模組12包括相互層疊設置的液晶層121、背光組件122以及部分包覆液晶層121與背光組件122的外框123。外框123為鐵框,其靠近蓋板11的一面部分包覆液晶層121,第一貼合部13直接貼合外框123與蓋板11,液晶層121相對外框123裸露的位置直接借由第二貼合部14與蓋板11貼合。
Please refer to FIG. 2, the
請參閱圖3,本實施例中,第一貼合部13為雙面背膠,其由依次層疊的第一感壓膠層131、第一底漆層132、橡膠層133、第二底漆層134及第二感壓膠層135構成。其中,第一底漆層132與第二底漆層134為用於提升黏著力的助黏劑,由於橡膠層133表面張力較低,導致第一感壓膠層131和第二感壓膠層135與橡膠層133之間的黏著力低於5N/25mm,第一底漆層132與第二底漆層134可增強第一感壓膠層131和第二感壓膠層135與橡膠層133之間的黏著力達到2N/25mm以上。

請參閱圖4,本實施例中,第一貼合部13沿顯示模組12的邊緣部設置,具體的,第一貼合部13沿外框123的邊緣部設置。本實施例中,第一貼合部13的外輪廓與外框123的外輪廓距離d為0.5至1毫米,且沿顯示裝置10的厚度方向,第一貼合部13在外框123上的投影位於外框123的外輪廓之內。
Referring to FIG. 4, in this embodiment, the
請再參閱圖1,第一貼合部13夾設在蓋板11與顯示模組12之間且與蓋板11與顯示模組12配合圍合形成一收容空間30。請再參閱圖4,本實施例中,第一貼合部13為一矩形環,收容空間30為矩形,第二貼合部14位於收容空間30內,本實施例中第二貼合部14由液態膠固化後形成,本實施例中第一貼合部13上開設有複數注膠開口136,每一注膠開口136與收容空間30連通,
所述液態膠由每一注膠開口136注入上述的收容空間30,經固化後形成第二貼合部14黏合顯示模組12與蓋板11。
Please refer to FIG. 1 again, the
本實施例提供的顯示裝置10,還包括軟性電路板(圖未示),軟性電路板設置於第一貼合部13上開設複數注膠開口136一側。由於第一貼合部13上開設複數注膠開口136一側的邊框寬度較大,有更大的空間利於設置軟性電路板,可有效避免軟性電路板影響顯示裝置10用於顯示圖像的區域。
The
進一步的,本實施例中第一貼合部13上還開設有複數排氣開口137,每一排氣開口137與收容空間30連通,由於所述液態膠在注入收容空間30的過程中為液態,其在流動過程中易產生氣泡,影響貼合效果,因此借由複數排氣開口137的設置,有利於排出氣泡,提升顯示模組12與蓋板的貼合強度。本實施例中,複數注膠開口136與複數排氣開口137皆開設於第一貼合部13的第一側壁上,使得複數排氣開口137的開設不影響收容空間30的容量(在開口的位置液態膠會溢出)。本實施例中,複數排氣開口137亦可用於注入液態膠,複數排氣開口137中的部分排氣開口137用作注入液態膠時,其餘排氣開口137則用作排氣。
Further, in this embodiment, the
請繼續參閱圖4,第一貼合部13上的第一側壁具有一外表面及與所述外表面相對設置的內表面,所述內表面設置為包括複數斜面138,每一斜面138相對所述外表面傾斜,且各斜面138相對所述外表面的傾斜方向不全相同。複數斜面138的設置,使得液態膠沿著斜面的傾斜趨勢流動,有利於排出氣泡、避免氣泡殘留影響顯示模組12與蓋板的貼合效果。請參閱圖5,於本發明另一實施例中,將第一貼合部13上的第一側壁的內表面整體設置為一個相對所述外表面傾斜的斜面(沿圖5虛線方向傾斜)。
Please continue to refer to FIG. 4, the first side wall on the
再進一步的,請繼續參閱4,本實施例中第一貼合部13上還開設有與收容空間30連通的兩個限位通道139,兩個限位通道139用於限定液態膠的注入量,具體的,由於液態膠的注入量超出兩個限位通道139將從限位通道139溢出,兩個限位通道139用於將液態膠的注入量在兩個限位通道139的開口以下(圖4中虛線以下)。兩個限位通道139分別開設於第一貼合部13的第二側壁與第三側壁上,第二側壁和第三側壁相對設置且與所述第一側壁相鄰連接。且,本實施例中兩個限位通道139位於第一貼合部13上的對稱位置,使得兩個限位通道139所限定的高度相同。
Still further, please continue to refer to 4. In this embodiment, the
請繼續參閱圖4,本實施例中,兩個限位通道139直線延伸。且本實施例中,兩個限位通道139的通道形狀相同,且兩個限位通道139的延伸方向相對第一貼合部13上的第一側壁傾斜,所述延伸方向相對第一貼合部13上的第一側壁傾斜的方向設置為:限位通道139靠近收容空間30的一端的限位高度低於限位通道139遠離收容空間30的一端的限位高度(限位通道139的限位高度定義為限位通道139與第一貼合部13上第一側壁所相對的側壁之間的距離)。上述限位通道139的延伸方向使得在注入液態膠過程中,液態膠不易從限位通道139溢出。
Please continue to refer to FIG. 4. In this embodiment, the two
請參閱圖6,在本發明一變更實施例中,兩個限位通道139非直線延伸,具體的,兩個限位通道139的通道形狀相同,且兩個限位通道139的通道的延伸軌跡為一曲線,由於曲面的斜率變化,使得限位通道139各處的高度不同,產生起伏,也有利於使得在注入液態膠過程中,液態膠不易從限位通道139溢出。
Referring to FIG. 6, in a modified embodiment of the present invention, the two limiting
請參閱圖7,在本發明另一變更實施例中,兩個限位通道139也非直線延伸,具體的,兩個限位通道139的通道形狀相同,個限位通道139的延伸軌跡為一鋸齒線,與圖6所示實施例類似的,本實施例中,限位通道139各處的高度不同,亦有利於使得在注入液態膠過程中,液態膠不易從限位通道139溢出。
Referring to FIG. 7, in another modified embodiment of the present invention, the two limiting
請再參閱圖2,本實施例提供的顯示裝置10,還包括設置於顯示模組12的外框123與第二貼合部14之間的密封膠層16,由於第二貼合部14為由液態膠固化後形成,液態膠在注入過程中為液態,具有較好的流動性,密封膠層16有利於阻絕液態膠向著顯示模組12內部流動,有利於保護顯示模組12的內部結構。
2 again, the
因此,本實施例提供的顯示裝置10,包括顯示模組12及蓋板11,借由第一貼合部13與第二貼合部14貼合顯示模組12與蓋板11,由於第二貼合部14為由液態膠固化後形成,其在注入顯示模組12及蓋板11之間時為可流動的液態,借由在第一貼合部13上設置限位通道139,可方便簡易地限定液態膠的注入量。並且,借由設置限位通道139的延伸軌跡,使得液態膠不易溢出。
Therefore, the
請參閱圖8,本實施例提供的觸控顯示裝置20,與實施例一的顯示裝置10的區別主要在於:還包括觸控模組22。
Please refer to FIG. 8, the
請繼續參閱圖8,本實施例的觸控顯示裝置20,包括依次層疊設置的蓋板21、觸控模組22及顯示模組23,其中,請參閱圖9,觸控模組22與顯示模組23借由第一貼合部24與第二貼合部25貼合。本實施例中,第一貼合部24如實施例一中所述的任意一第一貼合部13,第二貼合部25也如實施例一中所述的任意一第二貼合部14,此處不再贅述。
