Description
技术领域technical field
本发明涉及显示技术领域，尤其涉及一种显示屏以及拼接显示屏。The invention relates to the field of display technology, in particular to a display screen and a spliced display screen.
背景技术Background technique
现有的大尺寸的液晶显示屏通常是由多块尺寸相对较小的显示Existing large-size LCD screens are usually composed of multiple relatively small-sized displays
屏拼接而成。The screen is spliced together.
通常，现有的显示屏拼接结构如图1所示，彩膜基板1和阵列基板2之间设置有用于支撑显示面板的封框胶3，彩膜基板1的周边区域设置有黑矩阵4，液晶显示屏外侧还设置有包裹液晶显示屏的外框（Bezel）5，该外框5用于固定显示面板和背光源以及液晶显示屏中的其余各层结构。上述现有结构中，黑矩阵4和外框5均为全遮光的设计，如图1所示，显示面板周边的光线会被黑矩阵4以及外框5吸收或者阻挡，因此在两块显示屏相邻的区域会形成暗区（即拼接缝隙），造成图像的隔断。拼接缝隙越大，会使图像的隔断越明显，影响图像的连续性。因此，对于大尺寸拼接显示屏，需要其有较小的拼接缝隙以保证图像的连续性。通常，行业内采用B～B(Bezel～Bezel，即相邻两个显示屏的外框位于显示面板的显示面上的边缘之间的距离)或是A/A～A/A(ActiveArea～ActiveArea，即相邻两个显示屏的显示区域之间的距离)值来定义拼接屏连接缝隙，现有的显示屏拼接结构B～B或者A/A～A/A值均较大，如图1所示现有显示屏拼接结构示例中，B～B值为16.4mm，无法满足细化拼接屏的拼接缝隙以保证图像连续性的要求。Generally, the existing splicing structure of the display screen is shown in FIG. 1 , a sealant 3 for supporting the display panel is provided between the color filter substrate 1 and the array substrate 2 , and a black matrix 4 is provided in the peripheral area of the color filter substrate 1 . A bezel (Bezel) 5 wrapping the liquid crystal display is also provided outside the liquid crystal display, and the bezel 5 is used to fix the display panel, the backlight source and other layers in the liquid crystal display. In the above-mentioned existing structure, the black matrix 4 and the outer frame 5 are designed to be completely light-shielding. As shown in FIG. 1 , the light around the display panel will be absorbed or blocked by the black matrix 4 and the outer frame 5. Adjacent areas will form dark areas (that is, stitching gaps), causing image partitions. The larger the splicing gap, the more obvious the partition of the image will be, affecting the continuity of the image. Therefore, for a large-sized splicing display screen, it is required to have a small splicing gap to ensure the continuity of the image. Usually, the industry adopts B～B (Bezel～Bezel, that is, the distance between the outer frames of two adjacent display screens located on the display surface of the display panel) or A/A～A/A (ActiveArea～ActiveArea , that is, the distance between the display areas of two adjacent display screens) to define the splicing screen connection gap, the existing display screen splicing structure B~B or A/A~A/A values are relatively large, as shown in Figure 1 In the example of the existing display screen splicing structure shown, the values of B to B are 16.4 mm, which cannot meet the requirement of refining the splicing gap of the splicing screen to ensure image continuity.

具体实施方式detailed description
以下结合附图对本发明的具体实施方式进行详细说明。应当理解的是，此处所描述的具体实施方式仅用于说明和解释本发明，并不用于限制本发明，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。Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementations described here are only used to illustrate and explain the present invention, but not to limit the present invention. Apparently, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
作为本发明的一个方面，提供一种显示屏，该显示屏包括显示面板和围绕显示面板设置的外框，如图2所示，外框20可以包括透光部21和支撑部22，其中，透光部21至少覆盖支撑部22位于显示面板的显示面上方的部分，并且透光部位于显示面板的显示面上方的边缘超过支撑部22位于显示面板的显示面上方的边缘。As one aspect of the present invention, a display screen is provided, which includes a display panel and an outer frame arranged around the display panel. As shown in FIG. 2 , the outer frame 20 may include a light-transmitting portion 21 and a supporting portion 22, wherein The light-transmitting portion 21 covers at least the part of the support portion 22 above the display surface of the display panel, and the edge of the light-transmitting portion above the display surface of the display panel exceeds the edge of the support portion 22 above the display surface of the display panel.
现有的显示屏中，外框是由全遮光材料制成，显示面板周边的光线无法透光外框，因此，在由多个显示屏拼接形成的大尺寸显示屏中，两个显示屏外框相邻的部分会存在暗区，形成图像的隔断，影响图像的连续性。上述本发明所提供的显示屏中，外框20由透光部21和支撑部22组成，透光部21和支撑部22可以固定连接，并且，透光部21至少覆盖支撑部22位于显示面板的显示面上方的部分，且透光部21位于显示面板的显示面上方的边缘延伸超过支撑部22位于显示面板的显示面上方的边缘。上述结构中，支撑部22可以用于固定显示面板，并且与现有的显示屏相比，支撑部22的宽度可以小于现有显示屏的外框的宽度，而可以通过覆盖在支撑部22上的透光部21延伸本发明中外框的宽度，从而能够稳定固定显示面板。并且，上述结构中的透光部21能够透过光线，使得透光部21位于显示面板的显示面上方的边缘至支撑部22位于显示面板的显示面上方的边缘间的部分能够显示图像，因此，与现有技术相比，能够减小相邻显示屏间拼接缝隙的大小（即减小暗区面积），改善拼接屏显示图像的连续性。In the existing display screens, the outer frame is made of a full light-shielding material, and the light around the display panel cannot pass through the outer frame. Therefore, in a large-size display screen formed by splicing multiple display screens, the outer frame There will be dark areas in the adjacent parts of the frame, forming a partition of the image and affecting the continuity of the image. In the above-mentioned display screen provided by the present invention, the outer frame 20 is composed of a light-transmitting portion 21 and a supporting portion 22, and the light-transmitting portion 21 and the supporting portion 22 can be fixedly connected, and the light-transmitting portion 21 at least covers the supporting portion 22 and is positioned on the display panel. The portion above the display surface of the display panel, and the edge of the transparent portion 21 above the display surface of the display panel extends beyond the edge of the supporting portion 22 above the display surface of the display panel. In the above structure, the support part 22 can be used to fix the display panel, and compared with the existing display screen, the width of the support part 22 can be smaller than the width of the outer frame of the existing display screen, and can be covered by the support part 22 The light-transmitting portion 21 extends the width of the outer frame of the present invention, so that the display panel can be stably fixed. Moreover, the light-transmitting portion 21 in the above structure can transmit light, so that the portion between the edge of the light-transmitting portion 21 above the display surface of the display panel and the edge of the supporting portion 22 above the display surface of the display panel can display images, therefore , compared with the prior art, it can reduce the size of the splicing gap between adjacent display screens (that is, reduce the area of the dark area), and improve the continuity of the images displayed on the splicing screen.
更进一步地，透光部21可以包裹支撑部22。具体地，如图2所示，支撑部22可以设置在透光部21的内部，并被透光部21完全包裹。采用上述结构，易于加工形成由支撑部22和透光部21构成的外框，并且，将支撑部22设置在透光部21的内部，能够稳定地固定显示面板，同时也能够使透光部21和支撑部22位于显示面板的显示面上的边缘之间能够透过光线。Furthermore, the transparent part 21 can wrap the supporting part 22 . Specifically, as shown in FIG. 2 , the support part 22 may be disposed inside the light-transmitting part 21 and completely wrapped by the light-transmitting part 21 . With the above-mentioned structure, it is easy to process and form the outer frame composed of the support part 22 and the light-transmitting part 21, and the support part 22 is arranged inside the light-transmitting part 21, so that the display panel can be stably fixed, and the light-transmitting part can also be made 21 and the edge of the support portion 22 located on the display surface of the display panel can transmit light.
更进一步地，透光部21位于显示面板的显示面上的边缘与支撑部22位于显示面板的显示面上的边缘之间的距离为2mm～6mm。具体地，将透光部21位于显示面板的显示面上的边缘与支撑部22位于显示面板的显示面上的边缘之间的距离设置在2mm～6mm之间，能够使得有足够的空间使得光线透出，同时，能够通过透光部21延伸外框的宽度，从而能够稳定固定显示面板。Furthermore, the distance between the edge of the transparent portion 21 on the display surface of the display panel and the edge of the supporting portion 22 on the display surface of the display panel is 2mm˜6mm. Specifically, setting the distance between the edge of the light-transmitting portion 21 on the display surface of the display panel and the edge of the support portion 22 on the display surface of the display panel is between 2 mm and 6 mm, so that there is enough space for light to pass through. At the same time, the width of the outer frame can be extended by the light-transmitting portion 21, so that the display panel can be stably fixed.
更进一步地，显示面板可以包括阵列基板40和与阵列基板40相对设置的对盒基板50，其中，对盒基板上设置有黑矩阵10，且对盒基板50包括有效显示区和周边区域，且位于周边区域的黑矩阵10至少部分形成有通光部11。通常，对盒基板50周边区域的黑矩阵10为全遮光的设计，从显示区域射出的光线以及从封框胶30透过的光线会被黑矩阵10吸收或阻挡，因此，对盒基板50周边区域的黑矩阵10也会导致相邻的显示屏间形成暗区。上述本发明所提供的实施例中，黑矩阵10上形成有通光部11，使得光线能够从通光部11透过黑矩阵10，从而相对与现有技术，能够减小相邻显示屏间拼接缝隙的大小（即减小暗区面积），改善拼接屏显示图像的连续性。可以理解的是，上述对盒基板50可以包括彩膜层，以形成为彩膜基板。Furthermore, the display panel may include an array substrate 40 and a box-facing substrate 50 disposed opposite to the array substrate 40, wherein the box-facing substrate is provided with a black matrix 10, and the box-facing substrate 50 includes an effective display area and a peripheral area, and The black matrix 10 located in the peripheral area is at least partially formed with a light-transmitting portion 11 . Usually, the black matrix 10 in the peripheral area of the box substrate 50 is designed to be completely light-shielding, and the light emitted from the display area and the light transmitted from the sealant 30 will be absorbed or blocked by the black matrix 10. The black matrix 10 in the area will also result in the formation of dark areas between adjacent display screens. In the above-mentioned embodiment provided by the present invention, the black matrix 10 is formed with a light-transmitting portion 11, so that light can pass through the black matrix 10 from the light-transmitting portion 11, thereby reducing the distance between adjacent display screens compared with the prior art. The size of the splicing gap (that is, reducing the area of the dark area) improves the continuity of the image displayed on the splicing screen. It can be understood that the above-mentioned box matching substrate 50 may include a color filter layer, so as to be formed as a color filter substrate.
更进一步地，通光部11可以为在黑矩阵10上间隔设置的长条形的通孔。具体地，可以在黑矩阵10上间隔设置长条形通孔作为通光部11，使得光线可以从长条形通孔中穿过黑矩阵10。Furthermore, the light-transmitting portion 11 may be elongated through-holes arranged at intervals on the black matrix 10 . Specifically, strip-shaped through holes can be arranged at intervals on the black matrix 10 as the light-transmitting portions 11 , so that light can pass through the black matrix 10 through the strip-shaped through holes.
或者，通光部11可以为在黑矩阵10上按预设图形分布的圆形通孔。例如，可以如图3所示，在黑矩阵10上设置阵列形的圆形通孔作为通光部11，使得光线可以从圆形通孔中穿过黑矩阵10。Alternatively, the light passing portion 11 may be circular through holes distributed in a preset pattern on the black matrix 10 . For example, as shown in FIG. 3 , an array of circular through holes can be provided on the black matrix 10 as the light passing portion 11 , so that light can pass through the black matrix 10 from the circular through holes.
具体地，可以在对盒基板上制作黑矩阵时，采用构图工艺形成上述黑矩阵上的长条形通孔或者圆形通孔。Specifically, when the black matrix is fabricated on the box-matching substrate, a patterning process may be used to form the elongated through holes or circular through holes on the black matrix.
可以理解的是，上述仅为本发明所提供优选实施方式，除上述方式外，还可以采用别的结构在黑矩阵上形成通光部。It can be understood that the above is only a preferred implementation mode provided by the present invention, and other structures can also be used to form the light-transmitting portion on the black matrix in addition to the above-mentioned mode.
更进一步地，外框20的支撑部22可以由金属材料制成。具体地，支撑部22可以由金属材料制成，以能够保证外框的强度，从而能够稳定固定显示面板。Furthermore, the supporting part 22 of the outer frame 20 can be made of metal material. Specifically, the support part 22 can be made of metal material, so as to ensure the strength of the outer frame, so as to stably fix the display panel.
更进一步地，透光部21可以由有机玻璃制成。具体地，有机玻璃能够保证光线的透过率，同时，有机玻璃可以具有较好的韧性，使得外框能够稳定固定显示面板。上述仅为本发明所提供的优选方式，除上述方式外，透光部21也可以由光学透明树脂制成。Furthermore, the transparent part 21 can be made of organic glass. Specifically, the plexiglass can ensure light transmittance, and at the same time, the plexiglass can have better toughness, so that the outer frame can stably fix the display panel. The foregoing is only a preferred manner provided by the present invention, and besides the foregoing manner, the light-transmitting portion 21 may also be made of optically transparent resin.
作为本发明的另一方面，提供一种拼接显示屏，该拼接显示屏由多个显示屏拼接而成，且多个显示屏中至少两个为上述本发明所提供的显示屏。As another aspect of the present invention, a spliced display screen is provided. The spliced display screen is formed by splicing multiple display screens, and at least two of the multiple display screens are the above-mentioned display screens provided by the present invention.
更进一步地，拼接显示屏中的两个显示屏的外框相连接，并且相邻两个外框的支撑部位于显示面板的显示面上的边缘之间的距离在5mm～7mm之间。即，相邻显示屏的B～B(Bezel～Bezel)值在5mm～7mm之间，如图4所示示例中，外框中相连两侧的支撑部22的宽度为3.65mm，另外相连两侧的宽度为1.85mm，则拼接后相邻显示屏的B～B值为5.5mm，与现有技术相比，显著减小了拼接缝隙。Furthermore, the outer frames of the two display screens in the spliced display screen are connected, and the distance between the edges of the supporting parts of two adjacent outer frames on the display surface of the display panel is between 5 mm and 7 mm. That is, the values of B～B (Bezel～Bezel) of adjacent display screens are between 5mm～7mm. In the example shown in FIG. If the side width is 1.85mm, then the B-B values of the adjacent display screens after splicing are 5.5mm, which significantly reduces the splicing gap compared with the prior art.
上述为对本发明所提供的显示屏以及拼接显示屏进行的描述，可以看出，本发明的外框包括透光部和支撑部，使得外框在固定显示面板的同时，能够通过透光部透过光线，从而能够减小拼接显示屏中相邻显示屏间的拼接缝隙。此外，对盒基板的周边区域的黑矩阵上还可以设置有通光部，能够进一步使得光线可以从显示屏的周边透出，从而能够和上述外框配合以进一步减小相邻显示屏间的拼接缝隙。与现有技术相比，本发明能够显著改善拼接显示屏的图像的连续性。The above is a description of the display screen and the spliced display screen provided by the present invention. It can be seen that the outer frame of the present invention includes a light-transmitting part and a supporting part, so that the outer frame can pass through the light-transmitting part while fixing the display panel. Through the light, the splicing gap between adjacent display screens in the splicing display screen can be reduced. In addition, the black matrix in the peripheral area of the box substrate can also be provided with a light-transmitting part, which can further allow light to penetrate from the periphery of the display screen, so as to cooperate with the above-mentioned outer frame to further reduce the gap between adjacent display screens.
