下面将结合附图, 对本发明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发明一部分实施例, 而不是全部的实 施例。 基于本发明中的实施例, 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, 都属于本发明保护的范围。
本发明实施例提供了一种显示装置,该显示装置包括显示面板 10、 与所述显示面板 10连接的驱动模块 40、 设置在所述显示面板 10的入 光侧或出光侧的视差挡板、 以及设置在所述显示面板 10的至少一侧边 缘外侧的至少一个反射板 50。
其中, 所述显示面板 10至少包括多个第一显示单元 101和多个第 二显示单元 102。
所述驱动模块 40至少用于驱动所述显示面板 10 的所述多个第一 显示单元 101和所述多个第二显示单元 102分别进行图像显示。
所述视差挡板至少用于将所述多个第一显示单元 101 显示的图像 和所述多个第二显示单元 102显示的图像分别显示在预定视区。
所述至少一个反射板 50用于将靠近所述反射板 50 的视区显示的 图像反射到预定的其他视区。
其中, 本发明实施例中, 所述视差挡板例如可以优选为狭缝光栅 20, 所述狭缝光栅 20包括遮光部分 201和开口部分 202, 所述遮光部 分 201和所述开口部分 202相互间隔周期性排列, 即一个所述遮光部 分 201与相邻的一个所述开口部分 202构成一个狭缝光栅 20的周期。 此处例如通过合理设置狭缝光栅 20 的遮光部分 201 和所述开口部分 202的长度, 以及其开口部分 202与显示面板 10的显示单元的对应关 系、 狭缝光栅 20到显示面板 10 的入光侧或出光侧的距离等, 可以将 第一显示单元 101和第二显示单元 102显示的图像分别限定在希望显 示的视区。 选用狭缝光栅, 其结构相对简单, 并且对显示面板的厚度 影响较小, 有利于轻薄化。
需要说明的是, 第一, 本发明实施例中显示面板 10的一个显示单 元可以是一个亚像素, 也可以是由三个亚像素构成的一个像素, 又或 者是相邻接的多个像素, 在此不做限定。
第二, 本发明实施例中, 所述视差挡板可以为任意能将所述多个 第一显示单元 101显示的图像和所述多个第二显示单元 102显示的图 像分别显示在预定视区的部件, 其不限于是狭缝光栅 20, 例如还可以 采用液晶光栅、 电致变色材料光栅等其他形式。
第三, 所述至少一个反射板 50设置在所述显示面板 10的至少一 侧边缘外侧, 其中, 设置在一侧边缘外侧是指所述反射板 50紧挨显示 面板 10的一侧面放置。
第四, 所述至少一个反射板 50用于将靠近所述反射板 50 的视区 显示的图像反射到预定的其他视区, 即为: 若当所述反射板 50的设置 位置靠近某一个视区时, 所述反射板 50可以将显示在该视区的图像反 射到除该视区之外的其他希望看到该图像的视区; 至于通过所述反射 板 50将靠近其的视区显示的图像反射在其他哪个视区, 可以通过合理 设置所述反射板 50的角度来实现, 在此不再赘述。
由于反射板 50可以将靠近所述反射板 50的视区显示的图像反射 到其他视区, 对于位于其他视区的观看者来说, 不但可以看到其所在 的视区的图像, 也可以通过反射板 50看到所述反射板 50反射的图像。 这样, 当控制驱动模块 40使观看者在所在的视区仅能看到一幅完整图 像的一部分, 并通过反射板 50的反射, 使观看者能看到该一幅完整图 像的另一部分时, 相当于延伸了显示面板的长度, 从而可以达到图像 宽屏显示的目的。
可选的,如图 2所示,所述显示面板 10包括多个第一显示单元 101 和多个第二显示单元 102,第一显示单元 101和第二显示单元 102周期 性间隔排列。
所述驱动模块 40,用于驱动所述显示面板 10的所述多个第一显示 单元 101显示第一图像, 驱动所述显示面板 10的所述多个第二显示单 元 102显示第二图像。
所述视差挡板, 用于将所述第一图像显示在左视区 301, 将所述第 二图像显示在右视区 302。
这里, 参考图 2所示, 当所述视差挡板为狭缝光栅 20时, 且当一 个显示单元对应一个亚像素时, 可以将一个狭缝光栅 20周期对应大概 两个显示单元, 且将所述狭缝光栅 20的开口部分 202与第一显示单元 101 和第二显示单元 102 的交界处及附近对应, 以使位于左视区 301 的观看者可以看到多个第一显示单元 101 显示的第一图像, 使位于右 视区 302的观看者可以看到多个第二显示单元 102显示的第二图像。
所述显示装置包括一个反射板 50,所述一个反射板 50设置在所述 显示面板 10靠近所述右视区 302的边缘外侧, 并用于将显示在所述右 视区 302的所述第二图像反射到所述左视区 301。
其中, 显示在所述左视区 301 的所述第一图像、 以及反射到所述 左视区 301的所述第二图像的镜像构成一幅完整的图像。
这里, 所述第一图像和第二图像的镜像构成一幅完整的图像, 即 为: 通过人眼简单地将第一图像和第二图像的镜像拼合起来, 可直观 看到一幅完整的清楚的图像。 例如一张完整的图片, 从中间撕开, 其 中一半可以看作上述的第一图像, 另一半可以看作上述的第二图像的 镜像, 在不做任何方向转动的情况下, 将这两半的图片放在一起, 才 能形成一张完整的图片。
由于对于位于左视区 301和右视区 302的观看者来说, 其看到的 第一图像和第二图像均是显示在整个显示面板上的,当位于左视区 301 的观看者不但可以从左视区 301看到整个显示面板上显示的第一图像, 还可以通过反射板 50看到本应只能从右视区 302看到整个显示面板上 显示的第二图像时, 且当第一图像和第二图像的镜像是一幅完整的图 像时, 对于位于左视区 301 的观看者来说, 相当于从两个显示面板大 小的屏幕中看到由第一图像和第二图像的镜像构成的一幅完整的图 像, 从而实现宽屏显示的目的。
示例 1, 以使位于左视区 301的观看者看到如图 3a所示的画面为 例, 来说明本发明实施例提供可实现宽屏显示的显示装置的结构以及 实现宽屏显示的原理。
参考图 2所示, 显示装置包括: 显示面板 10、 与所述显示面板 10 连接的驱动模块 40、 设置在所述显示面板 10的出光侧的狭缝光栅 20、 以及设置在所述显示面板 10的靠近右视区 302的边缘外侧的一个反射 板 50。
其中, 所述显示面板 10包括多个第一显示单元 101和多个第二显 示单元 102,且第一显示单元 101和第二显示单元 102周期性间隔排列。 此处以一个显示单元对应一个亚像素为例。
所述狭缝光栅 20, 用于将所述多个第一显示单元 101显示的图像 显示在左视区 301,将所述多个第二显示单元 102显示的图像显示在右 视区 302 ο
这里, 可以将图 3a的画面分成两部分, 即如图 3b和图 3c所示的 "天下" 和 "为公" 。 此处, 若通过狭缝光栅 20的作用, 将 "天下" 显示在左视区 301, 将 "为公"显示在右视区 302, 当通过设置在靠近 右视区 302的边缘外侧的一个反射板 50的作用, 将 "为公"反射到左 视区 301后, 对于位于左视区 301的观看者来说, 其看到的将是图 3d 所示的 "为公" 的镜像, 这样, 对于位于左视区 301 的观看者来说, 其看到的必将不是一幅完整的清楚的图像,即其看到的是图 3b和图 3d 拼合在一起的图像。
因此, 为保证位于左视区 301 的观看者能看到的是一幅完整清楚 的图像, 例如如图 3e所示, 即看到的是正常阅读顺序的成语 "天下为 公" , 需要保证位于左视区 301的观看者从反射板中看到的是如图 3c 所示的 "为公" , 但是由于 "为公" 是经过镜像后看到的, 因此, 在 未镜像前对应于位于右视区 302 的观看者来说应该看到如图 3d 所示 的 "为公" 的镜像才可以。 这样, 就需要所述驱动模块 40驱动所述多 个第二显示单元 102显示如图 3d 所示的 "为公"的镜像, 相应的, 对 于位于右视区 302的观看者来说, 其看到的永远是镜像图像。
基于上述, 本示例中, 所述驱动模块 40, 用于驱动所述显示面板 10的所述多个第一显示单元 101显示第一图像即如图 3b所示的 "天 下" 、 驱动所述显示面板 10的所述多个第二显示单元 102显示第二图 像即如图 3d所示的 "为公" 的镜像。
所述狭缝光栅 20, 用于将所述第一图像即如图 3b所示的 "天下" 显示在左视区 301, 将所述第二图像即如图 3d所示的 "为公" 的镜像 显示在右视区 302。
这里, 当一个显示单元对应一个亚像素时, 可以使一个狭缝光栅 20周期对应大概两个显示单元, 且将所述狭缝光栅 20的开口部分 202 与第一显示单元 101和第二显示单元 102 的交界处及附近对应, 以使 位于左视区 301 的观看者可以看到多个第一显示单元 101显示的第一 图像即如图 3b所示的 "天下" , 位于右视区 302的观看者可以看到 多个第二显示单元 102显示的第二图像即如图 3d所示的 "为公" 的镜 像。 此外, 按这样的狭缝光栅 20与显示面板 10 的对应关系, 在左视 区 301和右视区 302之间必然会形成一个串扰区, 本示例并不在该串 扰区进行观看, 因此不做考虑。
此处需要说明的是, 对于所述驱动模块 40, 其如何将一幅完整图 像分割, 从而将其分割的一部分图像通过第一显示单元 101 显示, 另 一部分图像的镜像通过第二显示单元 102 显示, 在此不做限定, 根据 实际情况自行设定。
基于上述描述, 当然也可以将所述反射板 50设置在所述显示面板 10靠近所述左视区 301的边缘外侧, 以使位于右视区 302的观看者不 但可以从右视区 302看到整个显示面板上显示的第二图像, 还可以通 过反射板 50看到本应只能从左视区 301看到的整个显示面板上显示的 第一图像, 这样, 对于位于右视区 302 的观看者来说, 其相当于从两 个显示面板大小的屏幕中看到由第二图像和第一图像的镜像构成的一 幅完整的图像。
需要说明的是, 本领域技术人员在不需要做出创造性劳动的前提 下, 在所述显示面板 10至少包括多个第一显示单元 101和多个第二显 示单元 102, 且其排列顺序固定的情况下, 通过合理设置狭缝光栅 20 的所述遮光部分 201和所述开口部分 202的长度、以及其开口部分 202 与显示面板 10的显示单元的对应关系、 狭缝光栅 20到显示面板 10的 出光侧的距离等, 可以将第一显示单元 101和第二显示单元 102显示 的图像分别限定在希望显示的视区。
可选的, 如图 4所示, 所述显示面板 10包括所述多个第一显示单 元 101和所述多个第二显示单元 102,且第一显示单元 101和第二显示 单元 102周期性间隔排列。 所述驱动模块 40,用于驱动所述显示面板 10的所述多个第一显示 单元 101显示第三图像、 驱动所述显示面板 10的所述多个第二显示单 元 102显示第四图像。
所述视差挡板, 用于将所述第三图像显示在中间视区 303, 将所述 第四图像分别显示在左视区 301和右视区 302。
这里, 参考图 4所示, 当视差挡板为狭缝光栅 20, 且当一个显示 单元对应一个亚像素时, 可以使一个狭缝光栅 20周期对应大概两个显 示单元,且将所述狭缝光栅 20的开口部分 202例如与第一显示单元 101 对应,以使位于中间视区 303的观看者可以看到多个第一显示单元 101 显示的第三图像, 使位于左视区 301和右视区 302的观看者均可以看 到多个第二显示单元 102显示的第四图像。
所述显示装置包括两个反射板 50,所述两个反射板 50分别设置在 所述显示面板 10 靠近所述左视区 301 的边缘外侧和靠近所述右视区 302 的边缘外侧, 并用于分别将显示在所述左视区 301 和所述右视区 302的所述第四图像反射到所述中间视区 303。
在此情况下, 如果按照从左到右的观看习惯, 只需保证位于中间 视区 303的观看者可以从中间视区 303看到一幅完整图像的中间部分, 从靠近左视区 301和右视区 302的两个反射板 50看到该一幅完整图像 的左边部分和右边部分, 便可达到宽屏显示的目的。
其中, 对于位于中间视区 303 的观看者来说, 由于从靠近左视区 301和右视区 302的两个反射板 50看到的是完全相同的第四图像, 因 此, 只有从靠近左视区 301 的反射板中看到第四图像的镜像的右边部 分, 且从靠近右视区 302 的反射板中看到第四图像的镜像的左边部分 时, 才能是一幅完整并清楚的图像。 因而, 这里可以通过控制反射板 50的高度以及位于中间视区 303的观看者的位置, 来使其分别从两个 反射板中看到第四图像的镜像的一部分, 从而使其看到的一幅图像是 清楚的。 示例 2, 以使位于中间视区 303的观看者看到如图 3a所示的画面 为例, 来说明本发明实施例提供可实现宽屏显示的显示装置的结构以 及实现宽屏显示的原理。
参考图 4所示, 所述显示装置包括: 显示面板 10、 与所述显示面 板 10 连接的驱动模块 40、 设置在所述显示面板的出光侧的狭缝光栅 20、 以及分别设置在所述显示面板 10的靠近右视区 302的边缘外侧和 靠近左视区 301的边缘外侧的两个反射板 50。
其中, 所述显示面板 10包括所述多个第一显示单元 101和所述多 个第二显示单元 102,且第一显示单元 101和第二显示单元 102周期性 间隔排列。 此处以一个显示单元对应一个亚像素为例。
所述驱动模块 40具体用于驱动所述显示面板 10的所述多个第一 显示单元 101显示第三图像、 驱动所述显示面板 10的所述多个第二显 示单元 102显示第四图像。
所述狭缝光栅 20, 用于将所述第三图像显示在中间视区 303, 将 所述第四图像显示在左视区 301和右视区 302。
具体的, 可以使一个狭缝光栅 20周期对应大概两个显示单元, 且 将所述狭缝光栅 20的开口部分 202例如与第一显示单元 101对应, 以 使位于中间视区 303 的观看者可以看到多个第一显示单元 101显示的 第三图像, 使位于左视区 301和右视区 302 的观看者均可以看到多个 第二显示单元 102显示的第四图像。
在此情况下, 对于位于中间视区 303 的观看者来说, 其只要例如 按从左到右的观看顺序, 依次从靠近左视区 301的反射板 50、 中间视 区 303、靠近右视区 302的反射板 50看到如图 5a、 5b、5c所示的"天"、 "下为" 、 "公" 即可实现宽屏显示的目的, 即该显示装置在显示时 需保证至少从靠近左视区 301 的反射板看到 "天" , 从中间视区 303 看到 "下为" , 从靠近右视区 302 的反射板看到 "公" 。 然而由于左 视区 301和右视区 302显示的图像为相同的图像, 且只有当位于中间 视区 303 的观看者从靠近左视区 301 的反射板看到 "天" , 且 "天" 需靠近中间视区, 从靠近右视区 302 的反射板看到 "公" , 且 "公" 需靠近中间视区, 才能看到一幅完整的图像即 "天下为公" 。 因此, 根据镜像原理, 左视区 301 显示的第四图像需包括 "天" 的镜像, 右 视区 302 显示的第四图像需包括 "公" 的镜像, 且需要保证从靠近左 视区 301的反射板 50中看到的 "天" 靠近中间视区 303, 相应的, 左 视区 301显示的 "天"的镜像应该远离中间视区 303, 同理, 需要保证 从靠近右视区 302的反射板 50中看到的 "公" 靠近中间视区 303, 相 应的, 右视区 302显示的 "公" 的镜像应该远离中间视区 303, 这样, 在左视区 301和右视区 302显示相同图像的情况下, 其应该显示如图 5d所示的图像, 即 "天" 的镜像和 "公" 的镜像。
基于上述描述, 可以知道第三图像为如图 5b所示的 "下为" , 第 四图像为如图 5d所示的 "天" 的和 "公" 的镜像。 进一步地, 可通过 控制反射板 50的高度以及位于中间视区 303的观看者的观看位置来避 免位于中间视区 303的观看者看到如图 5e所示的画面。
其中, 如图 6所示, 例如当仅希望从靠近左视区 301 的反射板中 看到第四图像的镜像的一半时, 可通过限定反射板 50的高度以及观看 者的观看位置来实现, 即可以通过如下公式计算出反射板的高度与观 看者的观看位置之间的关系。
其中,假设显示面板的长度为 P,观看者距离显示面板的距离为 L, 反射板的高度为 X, 由于仅希望从反射板中看到一半的图像, 即相当于 向反射板的远离显示面板一侧延伸了半个显示面板的长度, 根据相似 三角形可以得出公式: = , 即 X=L/2。 因此, 根据最佳观看距离
P P/ 2
合理设置反射板 50的高度 (即为最佳观看距离的一半) , 便可使位于 中间视区 303的观看者看到如图 3a所示的一幅完整且清楚的画面。
基于上述, 本示例中, 所述驱动模块 40, 用于驱动所述显示面板 10的所述多个第一显示单元 101显示第三图像即如图 5b所示的 "下 为" 、 驱动所述显示面板 10的所述多个第二显示单元 102显示第四图 像即如图 5d所示的 "天" 的镜像和 "公" 的镜像。
此处需要说明的是, 对于所述驱动模块 40如何将一幅完整的图像 分割, 从而将其分割的中间部分画面通过第一显示单元 101 显示, 将 另外两部分画面分别取镜像并组合后通过第二显示单元 102 显示, 在 此不做限定, 根据实际情况自行设定。
可选的, 如图 7所示, 所述显示面板 10包括所述多个第一显示单 元 101、 所述多个第二显示单元 102以及多个第三显示单元 103, 且第 一显示单元 101、第二显示单元 102和第三显示单元 103依次循环排列。
所述驱动模块 40,用于驱动所述显示面板 10的所述多个第一显示 单元 101显示第五图像、 驱动所述显示面板 10的所述多个第二显示单 元 102显示第六图像、 驱动所述显示面板 10的所述多个第三显示单元 103显示第七图像。
所述视差挡板, 用于将所述第五图像显示在中间视区 303, 将所述 第六图像显示在左视区 301, 将所述第七图像显示在右视区 302。
这里, 当所述视差挡板为狭缝光栅 20, 且当一个显示单元对应一 个亚像素时, 可以使一个狭缝光栅 20周期对应三个显示单元, 以使位 于中间视区 303 的观看者可以看到多个第一显示单元 101显示的第五 图像, 使位于左视区 301 的观看者可以看到多个第二显示单元 102显 示的第六图像, 使位于右视区 302 的观看者可以看到多个第三显示单 元 103显示的第七图像。
所述显示装置包括两个反射板 50,所述两个反射板 50分别设置在 所述显示面板 10 靠近所述左视区 301 的边缘外侧和靠近所述右视区 302的边缘外侧,并用于分别将显示在所述左视区 301的所述第六图像 和显示在所述右视区 302的所述第七图像反射到所述中间视区 303。
其中, 显示在所述中间视区 303 的所述第五图像、 以及分别从靠 近所述左视区 301和靠近所述右视区 302的反射板 50反射到所述中间 视区 303 的所述第六图像的镜像和所述第七图像的镜像构成一幅完整 的图像。
由于对于位于中间视区 303、左视区 301和右视区 302的观看者来 说, 其看到的第五图像、 第六图像和第七图像均是显示在整个显示面 板上的, 当位于中间视区 303 的观看者不但可以从中间视区 303看到 整个显示面板上显示的第五图像, 还可以从反射板 50看到本应只能从 左视区 301和右视区 302分别看到在整个显示面板上显示的第六图像 和第七图像时, 且按例如从左到右的顺序看到第六图像的镜像、 第五 图像、 第七图像的镜像是一幅完整的图像时, 对于位于中间视区 303 的观看者来说, 其相当于从三个显示面板大小的屏幕中看到一幅完整 并清楚的图像, 从而实现宽屏显示的目的。
示例 3, 以使位于中间视区 303的观看者看到如图 3a所示的画面 为例, 来说明本发明实施例提供可实现宽屏显示的显示装置的结构以 及实现宽屏显示的原理。
参考图 7所示, 所述显示装置包括: 显示面板 10、 与所述显示面 板 10连接的驱动模块 40、 设置在所述显示面板 10的出光侧的狭缝光 栅 20、以及分别设置在所述显示面板 10的靠近右视区 302的边缘外侧 和靠近左视区 301的边缘外侧的两个反射板 50。
所述显示面板 10包括所述多个第一显示单元 101、 所述多个第二 显示单元 102以及所述多个第三显示单元 103, 且第一显示单元 101、 第二显示单元 102和第三显示单元 103依次循环排列。 此处以一个显 示单元对应一个亚像素为例。
所述驱动模块 40用于驱动所述显示面板 10的所述多个第一显示 单元 101显示第五图像、 驱动所述显示面板 10的所述多个第二显示单 元 102显示第六图像、 驱动所述显示面板 10的所述多个第三显示单元 103显示第七图像。
所述狭缝光栅 20, 用于将所述第五图像显示在中间视区 303, 将 所述第六图像显示在左视区 30 1, 将所述第七图像显示在右视区 302。 具体的, 可以使一个狭缝光栅 20周期对应大概三个显示单元, 且 使所述狭缝光栅 20的开口部分 202的中线与一组显示单元的中线基本 重合, 从而使位于中间视区 303 的观看者看到多个第一显示单元 101 显示的第五图像, 使位于左视区 301 的观看者看到多个第二显示单元 102显示的第六图像,使位于右视区 302的观看者可以看到多个第三显 示单元 103显示的第七图像。
其中, 所述一组显示单元由依次排列的一个第一显示单元 101、 一 个第二显示单元 102、 一个第三显示单元 103构成。 需要说明的是, 这 里的所述狭缝光栅 20的开口部分 202的中线与一组显示单元的中线的 对应关系并不是绝对的重合, 可以有一定的偏差。
在此情况下, 对于位于中间视区 303 的观看者来说, 其只要例如 按从左到右的观看顺序, 依次从靠近左视区 301的反射板 50、 中间视 区 302、靠近右视区 302的反射板 50看到如图 5a、5b、5c所示的"天"、 "下为" 、 "公" , 则能够实现宽屏显示的目的。 因此, 这里, 可将 第五图像显示为如图 5b 所示的 "下为" , 将第六图像显示为如图 5a 所示的 "天"的镜像, 将第七图像显示为如图 5c所示的 "公"的镜像。
基于上述, 本示例中, 所述驱动模块 40具体用于驱动所述显示面 板 10的所述多个第一显示单元 101显示第五图像即如图 5b所示的 "下 为" 、 驱动所述显示面板 10的所述多个第二显示单元 102显示第六图 像即 "天" 的镜像、 驱动所述显示面板 10 的所述多个第三显示单元 103显示第七图像即 "公" 的镜像。
此处需要说明的是, 对于所述驱动模块 40如何将一幅完整的图像 分割, 从而将其分割的中间部分画面通过第一显示单元 101 显示, 另 外两部分画面分别取镜像后通过第二显示单元 102 和第三显示单元 103显示, 在此不做限定, 根据实际情况自行设定。
基于上述各种可能的显示装置, 优选的, 所述反射板 50垂直设置 在所述显示面板 10的至少一侧边缘外侧。 这样可以使观看者从所在的 视区看到的画面与从反射板中看的画面处于一个平面。
