Abstract

The invention discloses an OLED display screen passive AC driving system comprising a control device and a drive device connected in sequence; the drive device comprises a line drive module and a column drive module respectively forming a line drive signal and a column drive signal; the control device output end is respectively connected with the line and column drive modules; the line and columndrive module output ends are respectively connected with the OLED display screen; the control device employs a single-chip microcomputer used for forming a control signal and a display signal that light up the OLED display screen; the single-chip microcomputer transmits control signals and display data to the drive device; the drive device is used for forming line and column drive signals, and outputs the display data to the OLED display screen for displaying. The OLED display screen passive AC driving system is simple in making process, can well solve the OLED display screen display brightness nonuniform problems, thus ensuring the OLED display screen to work safely and stably.

Description

technical field [0001] The invention relates to the field of organic light emitting diodes, in particular to a passive AC drive system for OLED display screens. Background technique [0002] OLED (Organic Light Emitting Diode) is a new type of display device, which has the advantages of active light emission, light weight, thin thickness, fast response and high efficiency, and can work in various harsh environments. In recent years, it has gained a lot of attention in the field of display technology Wide range of applications. [0003] In order to flexibly display more images and text information, the OLED display screen is usually made into a dot matrix structure, and a grayscale dot matrix image is formed by controlling the brightness of each point. In order to save the hardware overhead of the driving circuit, currently most OLED displays are driven by a matrix driving method, and the screen is divided into passive matrix and active matrix according to the introduction o...
