Problems solved by technology

In this way, it not only consumes a lot of memory space to store the display frame of the warning light, but also because the AP needs to transmit the display frame to the driver chip all the time, and the battery power of the mobile phone will be depleted due to frequent transmission, which cannot meet the requirements. Existing mobile phones need low power consumption and long standby time
[0004] Therefore, in the design of existing warning lamp function, there are still many deficiencies and need to be improved.

Abstract

A display driver with a warning lamp function comprises a display driving circuit, a counter and a plurality of warning lamp settings, wherein the display driving circuit drives a display panel to perform display; the counter counts in a plurality of counting sections; the plurality of warning lamp settings correspond to the plurality of counting sections respectively; each warning lamp setting comprises a position track and a line segment length of the warning lamp on the display panel; when the display driver is triggered to display frame data corresponding to an instant message on the display panel, the counter starts counting, and according to a count value of the counter and a counting section where the count value is located, the warning lamp is displayed on the display panel by using the position track and the line segment length in the corresponding warning lamp setting.

Description

technical field [0001] The invention relates to the technical field of warning light display of a mobile device, in particular to a display driver with a warning light function and a mobile device with the display driver. Background technique [0002] The existing Always On Display (AOD) technology is a mobile phone that can display the time, remaining battery power, and even incoming call messages and push messages on some areas of the screen when the screen is off. In the state of AOD activation, when the mobile phone receives an instant message sent by the application processor (Application Processer, AP), it will also display the notification of this instant message on a part of the screen, because the original screen has already displayed AOD related information , so it is easy for users to ignore the display of instant messages. Therefore, a notification light function is provided to apply to the state of the mobile phone in standby and the panel is off. When the mobil...
