Description
本发明涉及一种曲面显示器，尤其涉及一种调整背光源的分布密度以改善曲面屏幕的暗区问题的曲面显示器。 The present invention relates to a curved display, and more particularly to a curved display that adjusts the distribution density of a backlight to improve the dark area of a curved screen.
随着显示屏幕的尺寸变大，传统的平面屏幕占用的空间也随之变大，使用曲面屏幕可以减少占用空间。此外，曲面屏幕可以显示出环绕画面效果，提供比平面屏幕更佳的显示效果。因此曲面屏幕的应用也越来越广。 As the size of the display screen becomes larger, the space occupied by the conventional flat screen becomes larger, and the use of the curved screen can reduce the space occupied. In addition, the curved screen can display a surround effect, providing a better display than a flat screen. Therefore, the application of curved screens is also becoming wider and wider.
然而，使用薄膜晶体管液晶显示器(Thin film transistor liquid crystal display，TFT-LCD)面板作为曲面屏幕仍有缺点需要改善。请参阅图1，图1是曲面屏幕10显示暗区位置的示意图。采用TFT-LCD面板做为曲面屏幕10的制程与制造平板屏幕方法相同，但是后来是将整个模组进行弯曲，形成曲面屏幕10。然而曲面屏幕10在弯折（bending）的区域会出现暗区14。由于弯折后的曲面屏幕10会导致薄膜晶体管基板和彩色滤光基板错位(misalignment)，弯折角度越大的区域，错位也越严重。错位区域导致光线穿透率降低而形成暗区14。一般而言，暗区14亮度只有曲面屏幕10的中间点亮度的60%~80%。 However, using a thin film transistor liquid crystal display (Thin film transistor liquid crystal The display, TFT-LCD panel as a curved screen still has shortcomings that need to be improved. Please refer to FIG. 1. FIG. 1 is a schematic diagram showing the position of the dark area of the curved screen 10.

However, the curved screen 14 may have a dark area 14 in the region of the bending. Since the curved curved screen 10 causes the thin film transistor substrate and the color filter substrate to be misaligned, the region where the bending angle is larger is more serious. The misaligned area causes a decrease in light transmittance to form a dark area 14. In general, the dark area 14 brightness is only 60% to 80% of the brightness of the intermediate point of the curved screen 10.
暗区的存在会导致观众看到亮度不均的画面，因此降低曲面屏幕10的显示质量。 The presence of dark areas causes the viewer to see a picture of uneven brightness, thus reducing the display quality of the curved screen 10.

In the embodiment, the curvature of the first display area 151 is greater than the curvature of the second display area 152. For convenience of explanation, the first display area 151 is located at a region where the bending angle of the liquid crystal display panel 110 is the largest, and the first display area 151 is substantially elliptical. Because the curvature of the first display area 151 is greater than the curvature of the second display area 152, the display brightness of the first display area 151 may be lower than the second display area 152 at the same distribution density of the backlight 112. Therefore, in this embodiment, the distribution density of the plurality of backlights 112 is adjusted according to the brightness of the corresponding display area, so that the distribution density of the plurality of backlights 112 corresponding to the first display area 151 is greater than that corresponding to the second display area 152. The distribution density of the plurality of backlights 112.
因为对应于第一显示区151的多个背光源112的分布密度大于对应于第二显示区152的多个背光源112的分布密度，所以第一显示区151可以获得较高的亮度。在显示时，第一显示区151可以与第二显示区152的显示亮度调整一致，以改善第一显示区151因曲率较大导致暗区的现象。Since the distribution density of the plurality of backlights 112 corresponding to the first display area 151 is greater than the distribution density of the plurality of backlights 112 corresponding to the second display area 152, the first display area 151 can obtain higher brightness. When displayed, the first display area 151 may coincide with the display brightness adjustment of the second display area 152 to improve the phenomenon of the dark area caused by the large curvature of the first display area 151.
请参阅图5，图5是本发明第二实施例的背光模块108以及液晶显示面板106的示意图。液晶显示面板106包含中间显示区170、第一显示区171以及第二显示区172。在本实施例中，中间显示区170位于液晶显示面板106的中间，第一显示区171位于中间显示区170和第二显示区172之间，具体来说，第二显示区172是位于液晶显示面板106两侧末端。第一显示区171大致上呈椭圆型。因为液晶显示面板106的弯曲角度由中心向两侧增加，因此在同样的背光源112分布密度下，液晶显示面板106的显示亮度由中心往两侧减小。本实施例将多个背光源112的分布密度随着对应的显示区的亮度而调整，使得对应于第一显示区171的多个背光源112的分布密度小于对应于中间显示区170的多个背光源112的分布密度，大于对应于第二显示区172的多个背光源112的分布密度。也就是说，多个背光源112的分布密度也是随着液晶显示面板106由中心往两侧减小。Please refer to FIG. 5. FIG. 5 is a schematic diagram of a backlight module 108 and a liquid crystal display panel 106 according to a second embodiment of the present invention. The liquid crystal display panel 106 includes an intermediate display area 170, a first display area 171, and a second display area 172. In the embodiment, the intermediate display area 170 is located in the middle of the liquid crystal display panel 106, and the first display area 171 is located between the intermediate display area 170 and the second display area 172. Specifically, the second display area 172 is located in the liquid crystal display. The ends of the sides of the panel 106. The first display area 171 is substantially elliptical. Since the bending angle of the liquid crystal display panel 106 increases from the center to both sides, the display brightness of the liquid crystal display panel 106 decreases from the center to both sides at the same distribution density of the backlight 112. In this embodiment, the distribution density of the plurality of backlights 112 is adjusted according to the brightness of the corresponding display area, so that the distribution density of the plurality of backlights 112 corresponding to the first display area 171 is smaller than the plurality of corresponding to the intermediate display area 170. The distribution density of the backlight 112 is greater than the distribution density of the plurality of backlights 112 corresponding to the second display area 172. That is to say, the distribution density of the plurality of backlights 112 is also reduced as the liquid crystal display panel 106 is moved from the center to the both sides.
因为多个背光源112的分布密度也是随着液晶显示面板106由中心往两侧减小，所以第二显示区172可以获得较高的亮度，第一显示区171次之，中间显示区170获得较低的亮度。在显示时，中间显示区170、第一显示区171与第二显示区172的显示亮度调整一致，以改善第一显示区151因曲率差异导致液晶显示面板106产生暗区的现象。Since the distribution density of the plurality of backlights 112 is also decreased as the liquid crystal display panel 106 is reduced from the center to the both sides, the second display area 172 can obtain higher brightness, the first display area 171 is second, and the intermediate display area 170 is obtained. Lower brightness. During display, the display brightness adjustments of the intermediate display area 170, the first display area 171, and the second display area 172 are consistent to improve the phenomenon that the liquid crystal display panel 106 generates dark areas due to the difference in curvature of the first display area 151.
相较于现有技术，本发明将用于曲面显示器的背光模块上的多个背光源的分布密度随着液晶显示面板的曲率调整，可改善曲面显示器因薄膜晶体管基板和彩色滤光基板错位而形成暗区，导致显示画面亮度不均的技术问题。Compared with the prior art, the distribution density of the plurality of backlights on the backlight module used for the curved display is adjusted according to the curvature of the liquid crystal display panel, and the curved display can be improved due to the misalignment of the thin film transistor substrate and the color filter substrate. A dark area is formed, which causes a technical problem of uneven brightness of the display screen.
综上所述，虽然本发明已以较佳实施例揭露如上，但该较佳实施例并非用以限制本发明，该领域的普通技术人员，在不脱离本发明的精神和范围内，均可作各种更动与润饰，因此本发明的保护范围以权利要求界定的范围为准。In the above, the present invention has been disclosed in the above preferred embodiments, but the preferred embodiments are not intended to limit the invention, and those skilled in the art can, without departing from the spirit and scope of the invention, Various modifications and refinements are made, and the scope of the invention is defined by the scope of the claims.
