【具体实施方式】
本发明公开一种拼接显示屏， 作为本发明拼接显示屏的实施例一， 如图 1 至 6所示， 所述拼接显示屏包括两块相互拼接的液晶显示屏， 所述液晶显示屏 在拼接处形成拼接边框， 所述拼接显示屏还包括图像分割器和至少一块 OLED 显示屏， 所述 OLED显示屏的边框为透明的， 所述 OLED显示屏覆盖所述拼接 边框， 所述图像分割器把影像信号分割为多份， 并分别传送给液晶显示屏和 OLED显示屏进行显示。 在本实施例中， 所述 OLED显示屏形状为长条状。
本实施例所述的拼接显示屏至少两块相互拼接的液晶显示屏和一块 OLED 显示屏， 液晶显示屏在拼接处形成拼接边框， 利用 OLED显示屏覆盖所述拼接 边框， OLED显示屏和液晶显示屏一样可以显示非常细腻的画面，所述图像分割 器把影像信号分割为多份，并分别传送给 OLED显示屏和液晶显示屏进行显示， 并组成完整的画面。 本发明充分利用了 OLED显示屏的边框是可以做成透明的 这一优点， 由于透明边框不会影响液晶显示屏的显示， 所以整个拼接显示屏完 全消除了拼接边框， 解决了人们一直想解决而又解决不了的难题。 另外， 由于 OLED显示屏非常薄，可以通过粘合剂粘贴在拼接边框处，基本不会给人们带来 视觉上的明显影响， 现有技术中制作大面积的 OLED显示屏尚存在技术瓶颈， 本发明使用的 OLED显示屏只需要和拼接边框宽度相同或稍大即可， 总面积较 小， 所以容易制作。
一般情况下， OLED显示屏的色彩鲜艳程度高于液晶显示屏， 如果 OLED 显示屏和液晶显示屏的色彩鲜艳度差距过大， 就会影响使用者的舒适度， 为了 解决这个问题， 如图 3 所示， 本实施例所述的拼接显示屏还包括色彩较正器， 所述色彩较正器用于较正 OLED显示屏的影像信号， 使液晶显示屏和 OLED显 示屏色彩趋于一致， 提高使用者的舒适度。 作为色彩较正器的具体实施例， 如 图 4所示， 包括显示参数格式转换模块和色度和饱和度调整模块， 所述色度和 饱和度调整模块包括一预设的查找表， 所述显示参数格式转换模块用于把影像 信号中的 RGB格式的显示参数转换为 YCbCr参数， 色度和饱和度调整模块根 据 YCbCr参数在所述查找表中查找并改写为新的 YCbCr参数，所述显示参数格 式转换模块再把新的 YCbCr 参数转换为新的 RGB 格式的显示参数， 传送给 OLED显示屏进行显示。
所述预设的查找表是对 LCD显示屏和 OLED显示屏进行光学检测，通过实 验测试得到的， 并预先写在色度和饱和度调整模块内。 YcbCr显示参数中的 Y 代表亮度， CbCr代表的色度和饱和度， 此时我们不必对亮度进行调整， 只需要 对 CbCr所代表的色度和饱和度进行查表调整，就基本上可以实现拼接屏的均匀 显示， 而且在 YCbCr显示参数坐标系中修改色度和饱和度更直观、 更容易， 而 且实验测试及调试更加容易， 如图 5和图 6所示， 通过调整颜色矢量的角度来 调整色度， 通过调整颜色矢量的长度来调整饱和度。
如果将 OLED的边框尽可能的缩减， 会增加较多的成本， 而 OLED的边框 可以是透明的， 虽然不会影响液晶显示屏的显示， 透明的边框仍会遮挡后面的 LCD, 但仍然会降低被遮盖区域的亮度， 所以本实施例拼接显示屏还包括亮度 较正器， 所述亮度较正器用于增强液晶显示屏被 OLED显示屏的边框遮盖区域 的亮度， 使拼接显示屏所有区域的亮度趋于均匀。
相应的， 本实施例所述拼接显示屏的显示方法为利用图像分割器把影像信 号分割为多份， 分别传送给液晶显示屏和 OLED显示屏进行显示， 利用色彩较 正器较正传送给 OLED显示屏的影像信号， 以使液晶显示屏和 OLED显示屏色 彩趋于一致； 利用亮度较正器增强液晶显示屏被 OLED显示屏的边框遮盖区域 的亮度， 以使拼接显示屏所有区域的亮度趋于均匀。 作为本发明拼接显示屏的实施例二， 如图 7所示， 与实施例一不同之处在 于拼接显示屏由四块液晶显示屏组成， 形成一个呈十字形的拼接边框， 本实施 例中 OLED显示屏为十字形， 用于覆盖拼接边框。 图像分割器把影像信号分割 为五部分， 分别传送给液晶显示屏和 OLED显示屏进行显示。
作为本发明拼接显示屏的实施例三， 如图 8所示， 与实施例二不同之处在 于本实施例中 OLED显示屏为三块， 拼接成十字形， 用于覆盖拼接边框。 图像 分割器把影像信号分割为七部分， 分别传送给液晶显示屏和 OLED显示屏进行 显示， 本实施例 OLED显示屏为长条形， 结构筒单， 成本低。
以上内容是结合具体的优选实施方式对本发明所作的进一步详细说明， 不 能认定本发明的具体实施只局限于这些说明。 对于本发明所属技术领域的普通 技术人员来说， 在不脱离本发明构思的前提下， 还可以做出若干筒单推演或替 换， 都应当视为属于本发明的保护范围。
