Problems solved by technology

[0003] At present, when the driver chip (Driver IC) drives the OLED display panel (Panel) to display normally, the driver chip outputs the OLED enable signal (En) as a high level (3.3V); when encountering external interference (such as electrostatic discharge ( Electric-Static discharge (ESD for short) interference) leads to abnormal power failure of the drive chip. At this time, the output of the OLED enable signal (En) is low (GND), and the OLED display panel enters a black screen state and cannot be automatically restored. is not expected by those skilled in the art

Embodiment Construction

[0015] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the present invention.

[0016] Such as figure 1 As shown, this embodiment relates to a system for automatically restoring the display state of an OLED display panel, which is applied to a terminal device provided with a microprocessor. Specifically, the system includes an OLED display panel connected to the OLED display panel to control the OLED display panel. The display state of the display panel and the driver chip that outputs the OLED enable signal, are connected to the driver chip and the OLED display panel respectively, to supply power to the driver chip and the OLED display panel, and receive the OLED enable signal output by the driver chip. The driving chip is connected to monitor the monitoring unit of the OLED enabling signal output by the driving chip, and the monitoring unit is formed by a microprocessor; ...

Abstract

The invention relates to the technical field of displays, in particular to a system for automatically recovering a display state of an OLED display panel. According to the system, a general purpose input / output of a micro processor unit is connected with an OLED enable signal output end of a driving chip by means of a diode, so that the micro processor unit can monitor an OLED enable signal by means of the general purpose input / output, the micro processor unit automatically transmits a reset signal to re-initialize the driving chip when detecting that the OLED enable signal is in a failure state when terminal equipment is in an operating mode, so as to achieve the automatic resetting purpose of the driving chip, such that the OLED display panel automatically recover an original display image after transient black screen (in the resetting process), thereby achieving the effect of recovering normal display of the OLED display panel in the case of abnormal power failure of the driving chip.

Description

technical field [0001] The invention relates to the technical field of displays, in particular to a system for automatically restoring the display state of an OLED display panel. Background technique [0002] The organic light emitting diode (Organic Light Emitting Diode, OLED) display technology uses an organic material coating, which has the characteristic of self-luminescence. The OLED display screen has a large viewing angle and saves power, and has been widely used. The biggest feature of OLED display devices is that they can realize flexible display. Lightweight, bendable and portable flexible display devices made of flexible semiconductor substrates are an important development direction of OLED display devices. [0003] At present, when the driver chip (Driver IC) drives the OLED display panel (Panel) to display normally, the driver chip outputs the OLED enable signal (En) as a high level (3.3V); when encountering external interference (such as electrostatic dischar...
