具有指纹识别功能的显示面板、制备方法及显示装置
摘要：
本发明涉及显示技术领域，提出一种具有指纹识别功能的显示面板，该显示面板包括金属遮光层、电极层以及绝缘层；金属遮光层上设置有第一间隔区域；电极层上设置有第二间隔区域，第二间隔区域与第一间隔区域错位设置；绝缘层设于金属遮光层与电极层之间，绝缘层上设置有凹陷区域；凹陷区域在金属遮光层上的正投影至少部分位于第一边界和第二边界之间；第一边界为第一间隔区域远离第二间隔区域的侧壁在金属遮光层上的正投影，第二边界为第二间隔区域远离第一间隔区域的侧壁在金属遮光层上的正投影。使通过绝缘层折射至第一间隔区域的杂散光减少，从而使射至光电传感器的杂散光减少，使指纹采集对比度较高，所得指纹图像较清晰，指纹识别效果较好。
摘要（英）：

A display panel having a fingerprint recognition function, a manufacturing method, and a display device. The display panel comprises a metal light shielding layer (10), an electrode layer (12), and an insulating layer (11); the metal light shielding layer (10) is provided with a first interval region (101); the electrode layer (12) is provided with a second interval region (121), the second interval region (121) and the first interval region (101) are provided in a staggered manner; the insulating layer (11) is provided between the metal light shielding layer (10) and the electrode layer (12), and the insulating layer (11) is provided with a recessed region (111); an orthographic projection of the recessed region (111) on the metal light shielding layer (10) is at least partially located between a first boundary and a second boundary; the first boundary is an orthographic projection of the sidewall of the first interval region (101), away from the second interval region (121), on the metal light shielding layer (10). The second boundary is an orthographic projection of the sidewall of the second interval region (121), away from the first interval region (101), on the metal light shielding layer (10).
