Patent number: 11940680Abstract: The present invention provides a display panel and a display module. The display panel includes a first substrate, a first electrode layer, a light control layer, a second electrode layer, and a second substrate. The light control layer includes a first liquid crystal and light blocking layers. When no voltage is applied to the light control layer, the first liquid crystal is configured as an atomized liquid crystal for scattering light. When a voltage is applied to the light control layer, the first liquid crystal is configured as a transparent liquid crystal, thereby effectively improving an anti-peep performance of the display panel.Type: GrantFiled: November 23, 2020Date of Patent: March 26, 2024Assignee: Shenzhen China Star Optoelectronics Semiconductor Display Technology Co., Ltd.Inventors: Mingming Ni, Haotian Xu, Zhiqing Shi
