Embodiment Construction

[0014] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0015] In the embodiment of the present invention, a display control device including a main control module, a display control module, and a power supply module is used in an OLED display screen, and the display control module controls the power-on sequence, communication interface sequence, and initialization process of the display module. The control module caches the image data output by the main control module, and after the display module is powered on, encapsulates the image data into the corresponding OLED display data, and outputs the OLED display data to the display module, so that the disp...

Abstract

The present invention belongs to the image display technology field, and provides an OLED display screen and a display control device thereof. The display control device comprising a master control module, a display control module and a power module in the OLED display screen is employed; the display control module controls the power-on time sequence, the communication interface time sequence and the initialization process of the display module, the display control module performs buffer memory of the image data outputted by the master control module, after the power-on of the display module is completed, the image data is packaged as the corresponding OLED display data, and the OLED display data is outputted to the display module to allow the display module to display the OLED display data, and because the display control module employs a programmable logic controller which has strong interface resource, and therefore, different interface time sequences are configured for different display modules through the display control module, the development is simple, the versatility is high, and the bus resource of the master control module is saved.

Description

technical field [0001] The invention belongs to the technical field of image display, and in particular relates to an OLED display screen and a display control device thereof. Background technique [0002] OLED (Organic Light-Emitting Diode, Organic Light-Emitting Diode) display technology is a new generation of flat panel display technology that is more advanced than liquid crystal display technology. Compared with liquid crystal display technology, it has ultra-thin, high brightness, wide viewing angle and fast response speed. , wide temperature range, low power consumption and flexible display can be widely used in communication, computer and consumer electronics and other fields. [0003] At present, most OLED display screens use MCU (Microcontroller Unit, micro control unit) to control the interface timing of the display module, and use a parallel bus to complete data transmission. [0004] However, directly using the MCU to control the interface timing of the display ...
