摘要： Disclosed are a display control module and a display control method of a display device. The display control module includes a control signal generation module and a plurality of IP core modules. The control signal generation module shields an initial frame control signal based on an enabled underrun signal to generate a frame control signal which is disabled. The plurality of IP core modules are coupled to the control signal generation module, receive the frame control signal, and perform image processing on image data of the same frame based on the frame control signal, so as to generate display image data corresponding thereto. Therefore, when the display device displays abnormally, the plurality of IP core modules continue to perform image processing on a current frame based on the frame control signal.

摘要： An electronic display device has a panel that operates in conjunction with a light-emitting diode (LED) backlight. The device “slopes” or gradually ramps a change in brightness of an LED based on a target brightness value of the LED, a current brightness value of the LED, and temperature at the LED. The device also may limit power to the backlight based on an estimated power consumption of a current row of LEDs of the backlight and power consumption of the other rows of LEDs. The device also may determine a reduced voltage to supply to an LED based on a current to supply to the LED to cause the LED to operate. The device also may send an interrupt to the backlight to block updates to the backlight while image content is written to pixels of the panel. The device further compensates for aging of and temperature at an LED.
