Problems solved by technology

However, the conventional image quality adjustment circuit adjusts the image quality such as the color tone of the entire display panel, and various display settings (brightness (brightness), contrast, sharpness, tone, etc.)
As a result, for example, it is not possible to set the optimum or preferred display quality for the images observed on the side of the driver's seat and the side of the passenger seat respectively.
[0018] For example, the glare of the screen varies depending on the seat due to the incident direction of sunlight. However, in conventional multi-view display devices, only the image quality of the display panel as a whole can be adjusted. The picture quality is just right, but the image on the side of the passenger seat is also too bright, etc.
