preparation example Construction

[0047] Based on the same inventive concept, an embodiment of the present invention also provides a method for preparing an organic light-emitting display panel, such as Figure 4 shown, including:

[0048] S401, forming a first drive control circuit and a second drive control circuit in the light emitting area;

[0049] S402, respectively forming an organic light-emitting device electrically connected to the first driving control circuit in the light-emitting area, and forming an electrochromic device electrically connected to the second driving control circuit in the transparent area.

[0050] During specific implementation, in the above-mentioned preparation method provided by the embodiment of the present invention, the electrochromic device is prepared by physical vapor deposition, because the physical vapor deposition process will destroy the organic light-emitting layer, but the physical vapor deposition process will not destroy the electrochromic layer, thus forming an...

Abstract

The device discloses an organic light emitting display panel and a preparation method and a driving method thereof and a display device. An organic light emitting display device and an electro-chromicdevice are arranged into a horizontal structure, and the organic light emitting display device and the electro-chromic device are controlled to work through different driving control circuits, i.e. different voltage is inputted to the electro-chromic device to adjust different transmittance of the electro-chromic device by a second driving control circuit, the display effect of the display panelcan be enhanced when the electro-chromic device is in the shading state, and transparent display of different transmittance of the display panel can be realized when the electro-chromic device is in the light transmission state; and the voltage is inputted to the electro-chromic device through the second driving control circuit and the electro-chromic device is enabled to be in the shading state when the display panel is in the non-display state so that the shielding function of the display panel can be realized and the phenomenon of light leakage of the display panel in the non-display statecan be prevented.

Description

technical field [0001] The invention relates to the technical field of organic electroluminescence, and in particular to an organic light-emitting display panel, a preparation method, a driving method and a display device thereof. Background technique [0002] Organic light emitting displays (Organic Light Emitting Diode, OLED) have been widely used in digital products because of their thinness, lightness, power saving and other characteristics. Compared with the traditional Liquid Crystal Display (LCD), OLED display technology does not require a backlight source, and uses very thin organic material coatings and glass substrates. When current passes through, these organic materials will emit light. As a display device, the OLED display will also be affected by environmental factors, especially in a strong light environment, the display effect of the OLED display will also decline. [0003] The existing OLED display panel includes a light-emitting area and a transparent area...
