Abstract
The present disclosure discloses an electromagnetic pen display, which includes a display module, a light emitting module and an electromagnetic input module. The display module includes a liquid crystal display panel configured to display image frame and a dynamic dimming pad. The dynamic dimming pad being configured to generate a dynamic dimming signal based on information of the display image frame of the liquid crystal display panel. The light emitting module includes a light source driving board and a plurality of light sources. The light sources being correspondingly electrically connected to the light source driving board, the light source driving board being configured to correspondingly dynamically driving a light emission luminance of the plurality of light sources in response to receiving a dynamic dimming signal from the dynamic dimming pad. The electromagnetic input module is configured to selectively receive a write input signal. The present discloses further provides a method for driving the same.
