具体实施方式
下面详细描述本申请的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，旨在用于解释本申请，而不能理解为对本申请的限制。
下文的公开提供了许多不同的实施例或例子用来实现本申请的不同结构。为了简化本申请的公开，下文中对特定例子的部件和设置进行描述。当然，它们仅仅为示例，并且目的不在于限制本申请。此外，本申请可以在不同例子中重复参考数字和/或字母。这种重复是为了简化和清楚的目的，其本身不指示所讨论各种实施例和/或设置之间的关系。此外，本申请提供了的各种特定的工艺和材料的例子，但是本领域普通技术人员可以意识到其他工艺的可应用于性和/或其他材料的使用。
下面，参照附图1-图12，描述根据本申请第一方面实施例的显示模组100。
如图1所示，在显示模组100中，可以包括安装部件1、导光板2、灯条件3、以及支撑件4。结合图2，安装部件1包括设于导光板2的入光侧的侧板1b，侧板1b与导光板2的入光面21间隔开设置，也就是说，侧板1b与导光板2的入光面21之间具有间隙不接触。
结合图2和图3，灯条件3位于导光板2的入光面21与侧板1b之间，且灯条件3安装于侧板1b，支撑件4设置于侧板1b且支撑导光板2的入光面21，以限制导光板2的入光面21与灯条件3的相对距离。其中，“设置于”当作广义理解，例如可以是一体成型或装配相连等。
此外，需要说明的是，本文所述的“导光板2的入光面21”指的是灯条件3发光时光线进入导光板2时的侧面，即在显示模组100工作时，灯条件3发出的光通过导光板2的入光面21进入到导光板2内。另外，需要说明的是，导光板2可以具有一个或者多个入光面21，例如当导光板2为矩形板时，导光板2可以只有一个侧面为入光面21，导光板2还可以是相对的两个侧面均为入光面21，等等。
相关技术中的一些显示模组，为了限定导光板的侧面与灯条件之间的间距稳定，通常是在灯条件的电路板上设置支撑件，为了提高支撑件与电路板的连接可靠性和连接便利性，通常采用焊接金属打件作为支撑件，即利用焊接在电路板上的金属打件止抵导光板的侧面。然而，在显示模组实际工作的过程中，金属打件会向导光板接触传热，引起导光板的过热、热熔等问题，影响显示画面质量。
而根据本申请实施例的显示模组100，通过将“限制导光板2的入光面21与灯条件3的相对距离”的支撑件4设置在侧板1b上，而非设置在灯条件3上，从而无需考虑支撑件4与灯条件3的连接方便及可靠问题而选用金属材料制作支撑件4，而是可以选用一些隔热及耐热性能较好的材料(例如塑料)制作支撑件4，进而改善支撑件4将灯条件3的热量传递给导光板2的问题，因而有效地改善了导光板4受灯条件3的影响而发热及热熔的问题，保证了显示模组100的显示品质。
而且，相关技术中的金属打件还存在脱落的风险，一旦金属打件脱落，不但无法继续限制导光板与灯条件之间的间距，致使导光板和灯条件的距离可能缩小，加重导光板的过热、热熔等问题，而且脱落的金属打件还容易影响灯条件的正常发光，或者引发其他结构的显示异常问题。此外，脱落的金属打件还可能引发灯条件上的电路烧损，引发安全等问题。
而根据本申请实施例的显示模组100，通过将“限制导光板2的入光面21与灯条件3的相对距离”的支撑件4设置在侧板1b上，而非设置在灯条件3上，从而可以灵活地将支 撑件4设置成与侧板1b配合牢靠的多种结构形状，避免了支撑件4从灯条件3上脱落的风险，防止由于支撑件4的脱落而造成灯条件3的发光异常、或者造成其他结构的显示异常的问题，并且提高限制导光板2的入光面21与灯条件3相对距离稳定的可靠性。而且如上文所述，无需考虑支撑件4与灯条件3的连接方便及可靠问题而选用金属材料制作支撑件4，而是可以选用一些非导电材料(例如塑料)制作支撑件4，进而避免支撑件4引发灯条件3上的电路烧损，不会引发安全问题，使用安全性好。
综上，根据本申请第一方面实施例的显示模组100，通过将“限制导光板2的入光面21与灯条件3的相对距离”的支撑件4设置在侧板1b上，从而可以选用隔热及耐热性能较好的材料(例如塑料)制作支撑件4，而且可以灵活地将支撑件4设置成与侧板1b配合牢靠的结构形状，从而可以有效地改善灯条件3通过支撑件4向导光板2传热的问题、以及支撑件4的易脱落问题，从而改善了导光板2的发热严重及热熔等问题，保证了显示模组100的显示品质和使用安全。
需要说明的是，当显示模组100的尺寸或类型不同时，安装部件1的具体构成可以不同，例如下面将描述三个具体实施例，但是本申请不限于以下三个具体实施例。
实施例一，如图2所示，安装部件1为第一安装部件1A，第一安装部件1A同时包括背板11和散热器12，散热器12的侧壁构成侧板1b。由此，由于散热器12可以为具有良好导热性能的材料制成，因此，可以将灯条件3工作时散发的热量较为快速地吸收并散热，例如将吸收的热量传递给背板11和/或散热到空气中等等，从而使得显示模组100的工作稳定性更高，使用安全性更高。
实施例二，如图4所示，安装部件1为第二安装部件1B，第二安装部件1B仅包括背板11，背板11的侧壁构成侧板1b。由此，可以降低安装部件1的制作材料的使用，从而降低生产成本，此时，可以适用于一些结构尺寸较小的显示模组100。
实施例三，如图5所示，安装部件1为第三安装部件1C，第二安装部件1C仅包括散热器12，散热器12的侧壁构成侧板1b。由此，由于散热器12可以为具有良好导热性能的材料制成，因此，可以将灯条件3工作时散发的热量较为快速地吸收并散热，例如将吸收的热量传递出去，从而使得显示模组100的工作稳定性更高，使用安全性更高。
需要说明的是，散热器12可以为散热性能较好的材料制作，例如可以为铝型材等，另外，当安装部件1同时包括散热器12和背板11时，背板11和散热器12的连接方式不限，例如可以通过卡扣连接、螺纹连接(例如螺栓或螺钉)等方式连接，例如在图6所示的具体示例中，背板11上具有卡扣件110，卡扣件110可以对散热器12进行限位固定。
在本申请的一些实施例中，安装部件1除了可以包括侧板1b以外，安装部件1还可以包括底板1a，底板1a设于导光板2的厚度一侧的底板1a(例如图2和图3中所示的示例中，底板1a位于导光板2的F4侧)。由此，可以利用底板1a承载导光板2，提高显示模组100的结构可靠性。
需要说明的是，侧板1b位于底板1a的侧边位置且与底板1a呈非零夹角设置(例如90°或大致90°等等)，而且，侧板1b和底板1a可以具有连接关系，也可以不具有连接关系。
例如在上述图2所示的实施例一中，侧板1b与底板1a可以为散热器12的不同部分、具有连接关系，例如散热器12的底壁构成底板1a，散热器12的侧壁构成侧板1b。由此，可以提高散热器12的散热面积，提高散热效果。此外，为了进一步提高散热效果，还可以如图2所示，在散热器12的底壁、即底板1a上设置凹槽、凸起等结构，进一步加大散热面积。
再例如在上述图4所示的实施例二中，侧板1b与底板1a可以为背板11的不同部分、具有连接关系，例如背板11的底壁构成底板1a，背板11的侧壁构成侧板1b。由此，可以提高显示模组100的结构强度。
又例如在上述图5所示的实施例三中，侧板1b与底板1a可以为散热器12的不同部分、具有连接关系，例如散热器12的底壁构成底板1a，散热器12的侧壁构成侧板1b。由此，可以提高散热器12的散热面积，提高散热效果。此外，为了进一步提高散热效果，还可以如图2所示，在散热器12的底壁、即底板1a上设置凹槽、凸起等结构，进一步加大散热面积。
当然，本申请不限于此，侧板1b与底板1a也可以分别设置在不同的部件上、不具有连接关系，例如在本申请的另外一些实施例中，安装部件1A在同时包括背板11和散热器12时，散热器12可以仅具有侧壁以构成侧板1b，散热器12不具有底壁，以由背板11的底壁构成底板1a。
此外，在本申请的实施例中，安装部件1除了包括设于导光板2的入光侧的侧板1b以外，安装部件1还可以包括设置在导光板2的非入光侧的其他侧板，或者，安装部件1也可以不包括设置在导光板2的非入光侧的其他侧板，也就是说，导光板2的非入光侧不具有其他侧板，从而可以实现窄边框设计。
在本申请的实施例中，支撑件4与侧板1b的连接方式不限，例如可以是一体件或装配相连。例如在图2和图3所示的具体示例中，支撑件4与侧板1b装配相连，也就是说，支撑件4和侧板1b可以分别单独加工、再装配相连，从而使得支撑件4和侧板1b可以分别 选用不同的材料，同时满足侧板1b的吸热及散热、以及支撑件4的隔热及耐热要求，而且便于支撑件4与侧板1b的分别单独加工，降低加工难度。
需要说明的是，支撑件4与侧板1b装配相连的具体形式不限，例如可以通过粘接、螺纹连接(例如螺钉或螺栓)、卡扣连接以及插配连接(如后文所述插槽41与插件1b1插接配合)等方式装配。此外，当支撑件4与侧板1b为一体件时，指的是：支撑件4与侧板1b为一个整体部件，不可拆卸。此外，需要说明的是，例如当使用螺钉连接时，打入螺钉的方向不限，例如可以从内向外(如图3中所示的从F1至F2的方向)，或者从外向内(如图3中所示的从F2至F1的方向)，或者从上向下(如图3所示的从F3至F4的方向)等。
例如在一些实施例中，支撑件4和侧板1b中的一个具有插槽41，支撑件4和侧板1b中的另一个具有插件1b1(也就是说，如图3所示，当侧板1b上有插件1b1时，则支撑件4上有插槽41，如图7所示，当支撑件4上有插件1b1时，则侧板1b上有插槽41)，支撑件4和侧板1b通过插件1b1插配于插槽41，以至少限制支撑件4沿侧板1b的厚度方向(例如图3中所示F1-F2方向)运动。由此，可以提高支撑件4的装配可靠性和稳定性，并且保证支撑件4限制导光板2与灯条件3的相对距离稳定的可靠性。此外，通过插件1b1与插槽41配合连接时，可以不必额外引入例如螺栓等零部件，从而节省生产成本，而且可以简化装配工序，提高装配效率。
在一些实施例中，如图8和图9所示，当支撑件4具有插槽41时，支撑件4可以包括第一定位部42(例如图8中所示的支撑件4在S1表面的F1侧的部分)、第二定位部43(例如图8中所示的支撑件4在S2表面的F2侧的部分)和第三定位部44，第一定位部42和第二定位部43沿侧板1b的厚度方向(例如图8中所示F1-F2方向)间隔开，第三定位部44连接在第一定位部42和第二定位部43，且位于第一定位部42和第二定位部43的远离底板1a的一侧(例如图8中所示的F3方向的一侧)，插槽41限定在第一定位部42、第二定位部43之间，且插槽41位于第三定位部44的靠近底板1a的一侧(例如图8中所示的F4方向的一侧)。由此，支撑件4的结构简单，便于加工，且生产成本低，提升产线的可操作性。
在一些实施例中，如图9所示，当侧板1b上具有插件1b1时，侧板1b上可以具有减薄槽1b12，侧板1b的位于减薄槽1b12处的部分为插件1b1，结合图3，第一定位部42的至少部分配合于减薄槽1b12，以限制支撑件4沿侧板1b的长度方向(例如图9中所示F5-F6方向)运动。也就是说，当支撑件4与侧板1b插接配合时，插件1b1插入到插槽41内，此时第一定位部42的至少部分可以卡入到减薄槽1b12内，从而可以限定支撑件4在沿侧板1b的长度方向不会发生位移，由此，可以提高插件1b1与插槽41插接配合时的稳定性， 进一步提高支撑件4的装配可靠性和稳定性，避免支撑件4对灯条件3的安装或工作造成影响。
需要说明的是，减薄槽1b12的设置位置不限，例如在图9-图11所示的具体示例中，减薄槽1b12可以设置在插件1b1的远离导光板2的一侧，从而保证侧板1b的朝向导光板2的一侧光滑，方便加工。
例如在一些实施例中，如图9和图11所示，插件1b1上还可以具有限位槽1b11，结合图8，支撑件4还可以包括限位筋45，限位筋45设于第三定位部44的面向底板1a的一侧(例如图8中所示F4方向的一侧)，且限位筋45的两端分别与第一定位部42和第二定位部43相连，限位筋45配合于限位槽1b11，以限制支撑件4沿侧板1b的长度方向(例如图8中所示F5-F6方向)运动。
由此，支撑件4与侧板1b插接配合时，限位筋45可以插入到限位槽1b11内，从而限定支撑件4在沿侧板1b的长度方向(例如图8中所示F5-F6方向)不会发生位移，由此，可以提高插件1b1与插槽41插接配合时的稳定性，进一步提高支撑件4的装配可靠性和稳定性，保证支撑件4对灯条件3的避让可靠性，避免支撑件4对灯条件3的安装及工作造成干涉影响。
另外，可以理解的是，为了限制支撑件4沿侧板1b的长度方向运动，形成在插件1b1上的限位槽1b11可以沿侧板1b的厚度方向(如图9中所示的F1-F2方向)或大致沿厚度方向(即稍微倾斜于图9中所示的F1-F2方向)贯穿插件1b1。此外，需要说明的是，限位槽1b11和减薄槽1b12可以是并列的方案，也可以是择一的方案，以起到限制支撑件4沿侧板1b的长度方向运动的作用。
在一些实施例中，如图3所示，显示模组100还可以包括框体5，框体5的至少部分止挡在第三定位部44的远离底板1a的一侧(例如图3中所示F3方向的一侧)，以限制支撑件4朝向远离底板1a的方向(例如图3中所示的从F4到F3的方向)运动。由此，通过框体5可以防止支撑件4从侧板1b脱落，从而提高显示模组100的结构稳定性，此外，通过设置框体5止挡在第三定位部44远离底板1a的一侧(例如图3中所示F3方向的一侧)时，还可以起到保护支撑件4、灯条件3以及侧板1b的作用，从而提高显示模组100的使用寿命，同时还可以提高显示模组100的使用安全性。
需要说明的是，框体5可以通过卡扣连接、螺纹连接(包括螺钉或螺栓)等方式与安装部件1(如背板11或散热器12)相连，此外，当导光板2为矩形板且只有一侧为入光面21时，可以仅在入光侧设置框体5，而在导光板2的其他侧不设置框体5，从而实现窄边框设 计。另外，框体5除了具有限制支撑件4运动的作用之外，还可以具有限制导光板2沿导光板2的厚度方向(例如图3中所示F3-F4方向)运动的作用，以及防止漏光的作用。
另外，还需要说明的是，根据本申请实施例的框体5的材质不限，可以为塑胶件、橡胶件、金属件等等。此外，根据本申请实施例的框体5可以是电子设备1000的外观框体内的内部框体，也可以是电子设备1000的外观框体。
在一些实施例中，如图3和图8所示，第一定位部42位于侧板1b的远离导光板2的一侧(例如图3中所示F2方向的一侧)，第二定位部43支撑导光板2的入光面21，第一定位部42在侧板1b的长度方向(例如图8中所示F5-F6方向)上的长度L1大于第二定位部43在侧板1b的长度方向(例如图8中所示F5-F6方向)上的长度L2，(即L1＞L2)。由此，第一定位部42与减薄槽1b12配合处的尺寸可以较大，使得在限制支撑件4沿侧板1b长度方向上的位移时的结构强度较高。而且，由于第二定位部43在侧板1b的长度方向上的长度L2较小，使得第二定位部4不会占用过多的安装空间，从而避免支撑件4对灯条件3的安装及工作造成影响。
例如在一些具体实施例中，第一定位部42在侧板1b的长度方向(例如图8中所示F5-F6方向)上的长度L1可以为6mm左右，第二定位部43在侧板1b的长度方向(例如图8中所示F5-F6方向)上的长度L2可以为3mm左右，但本申请不限于此，上述长度L1与长度L2也可以根据例如散热器12、灯条件3以及显示模组100整体的尺寸等进行适当地调整，在此不作赘述。
在一些实施例中，如图3和图8所示，第一定位部42位于侧板1b的远离导光板2的一侧(例如图3中所示F2方向的一侧)，第二定位部43支撑导光板2的入光面21，第一定位部42在侧板1b的厚度方向(例如图8中所示F1-F2方向)上的厚度H1小于第二定位部43在侧板1b的厚度方向(例如图8中所示F1-F2方向)上的厚度H2，(即H1＜H2)。由此，第一定位部42在沿侧板1b厚度方向上占用的空间较小，利于显示模组100的窄边设计，而且，使得第二定位部42在支撑件4限定导光板2沿侧板1b厚度方向的位移时的结构强度较高。
例如在一些具体实施例中，第一定位部42在侧板1b的厚度方向(例如图8中所示F1-F2方向)上的厚度H1可以为2mm-3mm(例如可以是2mm、2.5mm、3mm等)，第二定位部43在侧板1b的厚度方向(例如图8中所示F1-F2方向)上的厚度H2可以根据需要进行设置，例如满足第二定位部43凸出于灯条件3的发光件(即使灯条件3的发光件、如后文所述的LED灯32的靠近导光板2的入光面的一侧到第二定位部43靠近导光板2的入光面的 一侧)的距离在0.5mm-0.6mm即可(例如可以是0.5mm、0.55mm、0.6mm等等)，但本申请不限于此，上述厚度H1与厚度H2也可以根据例如散热器12、灯条件3以及显示模组100整体的尺寸等进行适当地调整，在此不作赘述。
在一些实施例中，如图3和图12所示，支撑件4通过面接触支撑导光板2的入光面21。由此，可以降低导光板2的入光面21与支撑件4接触时的压强，从而可以在一定程度上降低导光板2损坏的风险，进而可以提高显示模组100的使用安全性，而且可以提高支撑件4限制导光板2的入光面21与灯条件3的相对距离的可靠性。
例如在图8和图12所示的具体示例中，当利用第二定位部43支撑导光板2的入光面21时，第二定位部43的面向导光板2的一侧表面可以为平面，从而不但方便加工，而且可以达到支撑件4通过面接触支撑导光板2的入光面21的效果。
根据本申请实施例的显示模组100中，灯条件3与侧板1b的连接形式不限，例如可以采用胶体粘贴等形式固定，例如在一些具体实施例中，灯条件3可以通过双面胶粘贴于安装部件1的侧板1b。
在一些实施例中，如图12所示，支撑件4避让灯条件3设置，也就是说，灯条件3和支撑件4分别利用侧板1b上的不同部位安装，或者说，支撑件4在侧板1b上的安装位置处未安装有灯条件3。由此，可以分别单独安装支撑件4和灯条件3，支撑件4和灯条件3的安装顺序可以无先后，装配灵活。
例如在图2和图12所示的具体示例中，当支撑件4避让灯条件3设置时，灯条件3包括沿直线依次排列的多个子灯条3a，每相邻的两个子灯条3a之间具有间隙空间3b，多个子灯条3a中位于两端的两个子灯条3a彼此远离的一侧也具有间隙空间3b，至少一个间隙空间3b设有支撑件4(即可以有一个、或若干个、或每个间隙空间3b设有支撑件4。但是，需要说明的是，每个间隙空间3b处的支撑件4是至少部分位于间隙空间3b内，例如支撑件4还可以具有一部分位于侧板1b的远离灯条件3的一侧。
例如在本申请的一些具体实施例中，当显示模组100为大尺寸时，灯条件3可以包括多个子灯条3a，每相邻的两个子灯条3a之间都设有支撑件4，且多个子灯条3a中位于两端的两个子灯条3a彼此远离的一侧也分别设有支撑件4，从而可以较为可靠地保证显示模组100的显示品质。需要说明的是，例如当多个子灯条3a沿左右方向排成一排时，“多个子灯条3a中位于两端的两个子灯条3a彼此远离的一侧”可以理解为，最左侧的子灯条3a的左侧，以及，最右侧的子灯条3a的右侧。
当然，本申请不限于此，当显示模组100为小尺寸时，灯条件3还可以仅具有一个子灯 条3a，该子灯条3a的长度两侧分别设有支撑件4，从而可以较为可靠地保证显示模组100的显示品质。需要时说明的是，灯条件3的类型不限，例如在本申请的一个具体实施例中，如图12所示，灯条件3可以为LED灯条，灯条件3可以包括基板31和设置在基板31上的多个LED灯32，多个LED灯32沿基板31的长度的延伸方向间隔且均匀分布，由此可以由多个LED灯32同时工作以满足显示模组100的显示需求。可以理解的是，发光二极管简称为LED。
当然，本申请不限于此，在本申请的另外一些实施例中，灯条件3的局部和支撑件4还可以利用侧板1b上的同一部位进行安装，也就是说，支撑件4在侧板1b上的安装位置处同时安装有灯条件3的局部。例如在图14所示的示例中，当支撑件4具有插槽41时，灯条件3的基板31(即电路板)的一部分伸入插槽41，这样，在安装的过程中，可以先将基板31固定在侧板1b上，然后再安装支撑件4，使得基板31的一部分与侧板1b的一部分(即上述插件1b1)同时进入到插槽41内。
在本申请的实施例中，支撑件4的材料不限，只需要具有良好的耐热性以及隔热性能即可，例如，支撑件4可以包括但不限于是塑料件，当支撑件4为塑料件时，塑料件的具体类型不限，需要满足其具有较好地隔热及耐热性能以及一定的强度即可，例如，聚碳酸树酯(PC)、或ABS、或PC和ABS的混合物等等，由此，支撑件4具有容易加工成型且生产成本低的优点。另外，根据本申请实施例的支撑件4还可以为透明件，从而支撑件4不会遮挡灯条件3发出的光进入导光板2，可以缩小支撑件4与灯条件3之间的间距，保证入光和显示效果。
此外，根据本申请实施例的显示模组100的其他构成例如反射片6和光学膜片7等对于本领域普通技术人员而言都是已知的，这里不再详细描述。
下面，根据附图13，描述根据本申请第二方面实施例的电子设备1000。
如图13所示，电子设备1000包括根据本申请第一方面实施例的显示模组100。需要说明的是，根据本申请实施例的电子设备1000的类型不限，例如可以为液晶电视机、液晶显示器等等，在电子设备1000的类型确定后，本领域技术人员可以知晓电子设备1000的其他构成。根据本申请实施例的电子设备1000，由于显示模组100的显示品质和工作安全性可以得到提升，从而可以提高电子设备1000的整体品质。
在本说明书的描述中，参考术语“一个实施例”、“一些实施例”、“示例”、“具体示例”、或“一些示例”等的描述意指结合该实施例或示例描述的具体特征、结构、材料或者特点包含于本申请的至少一个实施例或示例中。在本说明书中，对上述术语的示意性 表述不必须针对的是相同的实施例或示例。而且，描述的具体特征、结构、材料或者特点可以在任一个或多个实施例或示例中以合适的方式结合。此外，在不相互矛盾的情况下，本领域的技术人员可以将本说明书中描述的不同实施例或示例以及不同实施例或示例的特征进行结合和组合。
