本公开涉及显示技术领域,尤其涉及一种显示装置。
背景技术
近年来,随着显示装置的功能多样化的发展,各类显示装置已经越来越广泛和深入的应用在人们生活的各个方面。
现有技术中,对显示装置上位于显示面板的出光侧的前框进行固定时,通常需要将前框和后壳的边缘加宽,保证足够的用于安装连接杆的区域,以通过连接杆直接将前框和后壳之间固定连接。这样一来,就会由于连接杆的固定空间要求而占用前框边缘的位置,导致前框的边缘区域较大,不利于显示装置的窄边框设计。

具体实施方式
下面将结合本公开实施例中的附图,对本公开实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本公开一部分实施例,而不是全部的实施例。基于本公开中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本公开保护的范围。
如图1所示,对显示装置上位于显示面板04出光侧的前框01进行固定时,通常需要将前框01和后壳的边缘加宽,保证足够的用于安装连接杆05的区域,以使得如图2所示,通过连接杆05直接将前框01和后壳02之间固定连接。这样一来,就会由于连接杆05的固定空间要求而占用前框01边缘的位置,导致前框01的边缘区域较大,不利于显示装置的窄边框设计。
本公开实施例提供一种显示装置,如图3所示,包括背光模组03和显示面板04,还包括安装于显示装置的出光侧X的前框01,显示面板04位于前框01与背光模组03之间,连接杆05穿过背光模组03与前框01相连接。如图4所示,背光模组03包括对应显示面板04的位置的面板安装区域E以及位于与面板安装区域E相邻的周边区域D,连接杆05位于周边区域D中。
需要说明的是,背光模组03包括对应显示面板04的位置的面板安装区域E以及位于与面板安装区域E相邻的周边区域D,即背光模组03的面积大于显示面板04的面积,因此,能够将连接杆05设置于周边区域D中。
此外,如图5所示,显示面板04包括中心用于显示画面的显示区域FF(如图5所示,在图5中由于剖切位置限制,显示区域FF未表示完全),以及围绕显示区域FF周边的显示面板周边区域CC,前框01盖合在显示面板04的显示面板周边区域CC,并且与背光模组03固定连接,将处于二者之间的显示面板04的位置固定,不会影响显示面板04的显示区域FF的正常画面显示。
本公开实施例提供一种显示装置,包括背光模组和显示面板,还包括安装于显示装置的出光侧的前框,显示面板位于前框与背光模组之间,连接杆穿过背光模组的周边区域与前框相连接。背光模组包括对应显示面板的位置的面板安装区域以及位于与面板安装区域相邻的周边区域,连接杆位于周边区域中。将背光模组划分为用于安装显示面板的面板安装区域,以及位于与面板安装区域相邻的周边区域,连接杆通过背光模组的周边区域与前框固定连接,从而无需加宽前框的边缘就能直接与后壳固定连接,能够缩减现有技术中用于与后壳固定的前框的边缘区域,进而缩窄了显示面板的边框区域。
此外,为了保证显示装置中对于显示面板04的固定稳定可靠,如图7所示,显示装置还包括模组上框06,模组上框06位于显示面板04与前框01之间,连接杆05穿过背光模组03和模组上框06与前框01相连接。
还需要说明的是,本公开中的显示装置,当设置有模组上框06时,设置的模组上框06为沿显示面板04周边的显示面板周边区域CC设置的矩形中空框架,用于与背光模组03配合对显示面板04进行固定,因此,要使得显示装置的前框01得到有效的固定,就需要将显示面板04放置在背光模组03的面板安装区域E,在显示面板04的出光侧X盖合模组上框06,并将模组上框06固定在背光模组03上,通过显示面板04两侧的背光模组03和模组上框06将显示面板04固定,然后再通过连接杆05将前框01与模组上框06以及背光模组03之间固定连接,即能够将前框01的位置固定。
如图8所示,当显示装置中包括模组上框06时,模组上框06盖合在显示面板04的周边区域CC,并且与背光模组03固定连接,将处于二者之间的显示面板04的位置固定,同样不会影响显示面板04的显示区域FF的正常画面显示,且通过模组上框06和背光模组03固定连接,能够提高对显示面板04固定的稳定性。
此外,如图6所示,显示装置还包括设置在背光模组03的与显示装置的出光侧X背离的一侧处的后壳02,在背光模组03的周边区域D内设置有通孔O,后壳02的对应背光模组03的周边区域D的位置也设置有通孔O,连接杆穿过后壳02中的通孔和背光模组03中的通孔O与前框01相连接。或者,如图9所示,当显示装置还包括模组上框06时,模组上框06上也设置有通孔O,连接杆05穿过后壳02、背光模组03以及模组上框06中的通孔O与前框01相连接。
以下,以显示装置中包括有模组上框06的情形,对于显示装置上各个部件上设置通孔O的具体要求以及通过不同大小的通孔O的设置对前框01的固定方式进行详细的说明。
具体的,例如,如图8所示,在模组上框06、背光模组03上设置通孔O,通孔O的孔径均设置为与连接杆05的截面直径相配合,连接杆05在依次穿过模组上框06和背光模组03时,能够分别与模组上框06、背光模组03上的各个组件固定连接,从 而将前框01的位置固定。在此基础上,当显示装置还包括有后壳02时,在通过连接杆05将显示装置的前框01与背光模组03以及模组上框06之间固定连接后,再安装后壳02,并将后壳02连接固定在显示装置上,可以通过粘贴、压合、过盈配合等方式将后壳02固定,本公开对此不做限定。在后壳02上不需要设置用于穿过连接杆05的通孔O,这样一来,安装完成后的显示装置的后壳02为一个光滑完整的平面,连接杆05不会裸露在外。
又例如,如图10所示,可以将模组上框06、背光模组03以及后壳02上的通孔O的孔径均设置为与连接杆05的截面直径相同,连接杆05在依次穿过模组上框06、背光模组03以及后壳02时,能够分别与模组上框06、背光模组03上的各个组件以及后壳02固定连接,同时,模组上框06和背光模组03中的模组框架031又将显示面板04固定,这样一来,通过连接杆05的连接,就能够使得整个显示装置上的各个部件之间均固定连接,从而不再需要在显示装置上设置其他的连接部件。
又例如,如图11所示,还可以将模组上框06和后壳02上的通孔O的孔径均设置为与连接杆05的截面直径相配合,将背光模组03上各个组件上的通孔O的孔径均设置为大于连接杆05的截面直径,这样一来,连接杆05在依次穿过模组上框06、背光模组03以及后壳02时,由于模组上框06和后壳02上的通孔O的孔径均与连接杆05的截面直径相配合,连接杆05穿过模组上框06和后壳02上的通孔O时,与模组上框06和后壳02之间相互配合紧密连接并且相对位置固定,由于背光模组03各个组件上的通孔O的孔径大于连接杆05的截面直径,则连接杆05在穿过背光模组03的各个组件时,不与背光模组03的各个组件相接触,避免由于背光模组03内的光学膜材032和导光板033等组件的厚度较薄,且材质较软,不易与连接杆05连接固定的问题。
由于背光模组03上的模组框架031需要与模组上框06共同对显示面板04进行位置的固定,因此,使用上述连接杆05的连接方式,还需要将背光模组03单独与前框01或者后壳02固定连接,使背光模组03与前框01或后壳02之间位置关系保持固定。
再例如,如图12所示,将模组上框06和后壳02上的通孔O的孔径均设置为与连接杆05的截面直径相配合,将背光模组03中的模组框架031以及背板034上的通孔O的孔径也设置为与连接杆05的截面直径相配合,背光模组03中光学膜材032和导光板033上的通孔O的孔径设置为大于连接杆05的截面直径,这样一来,一方面,由于模组上框06、模组框架031、背板034以及后壳02中的通孔O的孔径均与连接杆05的截面直径相配合,连接杆05穿过模组上框06、模组框架031、背板034以及后壳02中的通孔O时,与模组上框06、模组框架031、背板034以及后壳02之间相互配合紧密连接并且相对位置固定,由于背光模组03中的模组框架031以及背板034均与连接杆05固定连接,光学膜材032和导光板033固定在背板034的内侧,也就 使得背光模组03以及背光模组03内的各组件的位置固定;另一方面,由于背光模组03中光学膜材032和导光板033中的通孔O的孔径设置为大于连接杆05的截面直径,能够使得连接杆05穿过光学膜材032和导光板033上的通孔O且不与光学膜材032和导光板033相接触,避免光学膜材032和导光板033不易与连接杆05连接固定的问题。
以下,以如图12所示的通过连接杆05将前框01、模组上框06、模组框架031、背板034以及后壳02固定连接的连接方式为例,举例对连接杆05以及与连接杆05相配合的通孔O的具体设置和连接方式进行详细的说明。
例如,如图13所示,连接杆05为螺栓051,与螺栓051相配合的,在前框01上对应连接杆05的位置设置有螺纹孔O′,螺栓051与螺纹孔O′相配合将前框01连接固定。
螺栓051的圆柱侧面加工有螺纹,螺纹孔O′的内壁上也加工有螺纹,螺栓051上的螺纹与螺纹孔O′内壁的螺纹的螺距、旋向以及螺旋升角相同,使得螺栓051拧入螺纹孔O′时,螺栓051上的螺纹能够与螺纹孔O′内壁的螺纹相互配合,从而不需要另外增加相配合的螺母,即可通过螺栓051将设置有螺纹孔O′的前框01与模组上框06、模组框架031、背板034以及后壳02之间均固定连接。
对于不需与前框01接触的光学膜材032和导光板033,只需将光学膜材032和导光板033上螺纹孔O′的孔径增大,即可避免与螺栓051上的螺纹相旋接。
本公开中对于螺纹的平面图形形状不做具体限定,三角形、矩形、梯形和锯齿形螺纹等均可,对于螺纹的旋向以及螺旋升角也不做具体限定,只要能够实现通过相互配合的螺纹将螺栓051与螺纹孔O′拧紧固定在螺纹孔O′内即可。
通过螺栓051与螺纹孔O′相配合将前框01连接固定,固定方式简单,螺栓051以及螺纹孔O′上的螺纹的加工难度不大,连接牢固稳定,且通过常规的螺丝刀即可完成安装或拆卸,便于显示装置的拆装操作。
进一步的,如图13所示,螺栓051选用全螺纹螺栓。
这样一来,当显示装置上的各部件之间的相对位置发生变化时,无需重新更换设置有相应的螺纹位置的螺栓051,只需根据相对位置的需要,增加或减少部件在螺栓051上的旋转圈数即可,操作简单,使用方便。
在此基础上,如图13所示,螺栓051选用沉头螺栓,沉头螺栓在安装完成后,尾部收于后壳02上的凹槽内,一方面,能够减小显示装置安装完成后的总厚度,另一方面,使得显示装置外观的视觉效果较为美观。
又例如,如图14所示,连接杆05为定位销052,与定位销052相配合的,在前框01上对应连接杆05的位置设置有定位孔O〞,定位销052与定位孔O〞之间过盈配合。
定位孔O〞的孔径小于定位销052的轴径,通过专用的过盈配合安装工具将定位 销052安装入定位孔O〞内之后,定位销052和与之配合的定位孔O〞即可紧密配合为一体,或者还可以根据热胀冷缩的原理,在过盈配合安装时,将定位销052加热,或者将设置有定位孔O〞的部件降温,待相互配合安装完成后恢复至常温即可实现过盈配合。
根据过盈配合的两个部件的材质不同,需要对过盈配合的两个部件的孔径和轴径的设置关系进行具体的计算,并根据计算数值进行尺寸的加工,本公开对于此过盈配合关系中的两个部件的具体尺寸不做限定,只要能够实现定位销052与定位孔O〞之间过盈配合的紧密连接即可。
此外,如图14所示,定位销052的端面W为平面。
这样一来,在前框01上定位孔O〞的尺寸不变的情况下,由于定位销052的端面W为平面,消除了定位销052的端部向定位孔O〞的底部延伸的长度,使得定位销052与前框01的定位孔O〞的侧壁之间的接触高度h为最大,以增加定位销052与定位孔O〞之间过盈配合部分的接触面积,提高定位销052与定位孔O〞之间的固定连接的稳定性。
在此基础上,如图14所示,定位销052选用尾部为平面的圆柱销,这样一来,当圆柱销完成显示装置前框01的固定后,圆柱销的尾部能够完全与后壳02的外表面保持平齐,使得后壳02的外表面形成一个光滑的平面,进一步提高显示装置外观的美观性。
再例如,如图14所示,在前框01上对应连接杆05的位置设置有定位孔O〞,如图15所示,定位孔O〞内以及连接杆05插入定位孔O〞的一端设置有相互配合的卡合结构07,相互配合的卡合结构07将连接杆05与定位孔O〞卡接固定。
以下,对相互配合的卡合结构07在连接杆05以及定位孔O〞的具体设置位置进行详细说明。
例如,如图15所示,相互配合的卡合结构07为在连接杆05插入定位孔O〞的一端的侧壁上设置的凸部以及在定位孔O〞的侧面设置的凹部,或者,如图16所示,在连接杆05插入定位孔O〞的一端的侧壁上设置的凹部以及在定位孔O〞的侧面设置的凸部。
又例如,如图17所示,相互配合的卡合结构07为在连接杆05插入定位孔O〞的一端的端面上设置的凸部以及在定位孔O〞的底面设置的凹部,或者,如图18所示,在连接杆05插入定位孔O〞的一端的端面上设置的凹部以及在定位孔O〞的底面设置的凸部。
本公开对于卡合结构07的具体形状不做限定,可以为如图15-18所示的圆弧形,也可以为三角形,梯形、矩形等,只要能够实现配合卡合即可,为了进一步提高连接杆05的固定连接效果,卡合结构07还可以设置为多个,本公开对于卡合结构07的设置数量也不做限定。此外,当卡合结构07为设置在连接杆05的侧壁上时,卡合结 构07还可以为在连接杆05的侧壁上沿水平方向设置的环状结构,与之相配合的,定位孔O〞的侧面也为沿水平方向设置的环状结构即可。
上述的连接方式,对于显示装置中不包括模组上框06同样适用,此处不再赘述。
以上所述,仅为本公开的具体实施方式,但本公开的保护范围并不局限于此,任何熟悉本技术领域的技术人员在本公开揭露的技术范围内,可轻易想到变化或替换,都应涵盖在本公开的保护范围之内。因此,本公开的保护范围应以所述权利要求的保护范围为准。
