Abstract

A device for detecting a light leakage defect of a touch panel, comprising a device body (1). The device body (1) comprises a shell (17) formed by a detection panel (11), side plates (12, 13, 14, 15), and a bottom plate (16) that are assembled together, and a light source (3) fixedly provided in the shell (17), wherein the detection panel (11) is a transparent panel, so that light emitted by the light source (3) can pass through the detection panel (11) configured to carry a product to be tested. By using the light leakage detection device, an inspector does not need to keep lifting a to-be-tested product under a desk lamp to observe the light leakage; in addition, the light leakage detection operation is also simplified because the inspector only needs to directly observe the ink print of the to-be-tested product on the detection panel (11), so as to determine whether light leakage occurs in the to-be-tested touch panel product, without sequentially rotating four sides of the to-be-tested touch panel. This not only simplifies the steps for detecting light leakage of a touch panel, but also improves the light leakage detection speed and efficiency.

Description

一种用于检测触摸面板漏光缺陷的装置Device for detecting light leakage defect of touch panel 技术领域Technical field
本发明涉及触摸面板的检验技术领域，具体是一种用于检测触摸面板漏光缺陷的装置。The invention relates to the technical field of inspection of a touch panel, in particular to a device for detecting light leakage defects of a touch panel.
背景技术Background technique
作为智能手机、平板电脑等智能终端的关键部件——触摸面板的性能直接影响了智能终端的视觉效果、触摸灵敏度等。在触摸面板结构中，如图1所示，既包括用于显示图像的显示区域100，又包括布置有走线结构的触摸面板区域200。为了优化触摸面板的外观，增强显示效果并且遮盖走线结构，该触摸面板区域200上可根据产品需求印刷不同颜色的油墨(如黑色、白色、金色、银色或红色等)。考虑到印刷工艺的误差，当油墨未完全印刷到触摸面板区域上时，来自液晶模组的光线就可能穿透出未印刷有油墨之处的触摸面板区域，导致触摸面板漏光，给用户带来不良的视觉体验。因此，触摸面板在出厂前需要进行漏光检验。As a key component of smart terminals such as smartphones and tablets, the performance of touch panels directly affects the visual effects and touch sensitivity of smart terminals. In the touch panel structure, as shown in FIG. 1, both the display area 100 for displaying an image and the touch panel area 200 in which a routing structure is arranged are included. In order to optimize the appearance of the touch panel, enhance the display effect and cover the trace structure, the touch panel area 200 can print different colors of ink (such as black, white, gold, silver or red, etc.) according to product requirements. Considering the error of the printing process, when the ink is not completely printed on the touch panel area, the light from the liquid crystal module may penetrate the touch panel area where the ink is not printed, causing the touch panel to leak light, bringing the user Bad visual experience. Therefore, the touch panel needs to be tested for light leakage before leaving the factory.
现有的检验触摸面板是否漏光的方法通常是：检验人员将待测产品放置在台灯下，通过对印刷有油墨的触摸面板区域进行观察，判断待测产品是否存在漏光问题。但是这种方法需要检验人员依次旋转触摸面板的四条侧边进行检验，且需要长时间举起面板面对台灯观察，易造成检验人员肢体疲惫，可见这种检验方式存在操作不便、检验速度慢、效率低等问题，实有必要对其进行改进。 The existing method for checking whether the touch panel leaks light is generally: the inspector places the product to be tested under the desk lamp, and observes the area of the touch panel printed with the ink to determine whether the product to be tested has a light leakage problem. However, this method requires the inspector to rotate the four sides of the touch panel in turn for inspection, and it is necessary to lift the panel to face the desk lamp for a long time, which is easy to cause the limbs of the inspector to be exhausted. It can be seen that the inspection method has inconvenient operation and slow inspection speed. For problems such as low efficiency, it is necessary to improve it.
