Abstract

The invention provides a terminal device and a diffusion degree adjusting method. The terminal device comprises a display panel, a diffusion unit, an ambient light detection unit and a control unit, wherein the display panel is arranged and used for displaying images / videos based on provided image / video data; the diffusion unit is arranged on the display panel, corresponds to the display panel in size and can change the diffusion degree based on the voltage applied to the diffusion unit; the ambient light detection unit is arranged on one side of the display panel and used for detecting ambient light around the display panel and generating ambient light data related to the ambient light; the control unit is arranged and used for receiving the ambient light data and controlling the voltage applied to the diffusion unit according to the ambient light data to change the diffusion degree of the diffusion unit.

Description

technical field [0001] The invention relates to a terminal device and a method for adjusting its scattering degree. Background technique [0002] Currently, OLED displays have been widely used in terminal devices such as smart phones and tablet computers. Due to the self-luminous characteristics of the OLED panel in the OLED display and the strong reflectivity of the metal cathode of the pixel of the OLED panel, the OLED panel is under strong The display does not look good in light. In the prior art, polarizers (to absorb part of the ambient light) and 1 / 4 glass are usually added on the OLED panel to reduce the impact of ambient light on the OLED panel, but the additional polarizer and 1 / 4 glass are also The self-luminescence of the OLED panel will be attenuated, thereby reducing the brightness of the OLED display. In this case, in order to increase the brightness, the power consumption of the OLED display has to be increased, thereby reducing the battery life of the termi...
