Embodiment 1

[0036] figure 1 It is a schematic structural diagram of a display device provided in Embodiment 1 of the present invention, the display device includes an organic light emitting display panel 110 and a liquid crystal display panel 120 covering the organic light emitting display panel 110 .

[0037] It should be noted that, in order to realize that the organic light-emitting display panel 110 and the liquid crystal display panel 120 do not interfere with each other during time-sharing display, the liquid crystal display panel 120 should be a transparent panel without a backlight, because if the liquid crystal display panel 120 If the backlight is included, it will shield the lower organic light emitting display panel 110 . Meanwhile, in order to enable the liquid crystal display panel 120 to perform normal display, the organic light emitting display panel 110 needs to provide it with a backlight. Considering that the organic light-emitting display panel 110 generally includes ...

Embodiment 2

[0068] Figure 7 It is a flow chart of a screen switching method provided in Embodiment 2 of the present invention. The method is used to switch and control any of the display devices described in the embodiment of the present invention. The method can be executed by a screen switching system, and the system can be controlled by software and / or hardware, and generally can be integrated in various electronic devices including display devices (for example, smart watches or smart phones, etc.), the method includes:

[0069] S710. If it is determined that the condition for using the first screen is satisfied, turn on the liquid crystal display panel and turn off the organic light emitting panel, so as to use the liquid crystal display panel as a current display screen.

[0070] S720. If it is determined that the condition for using the second screen is satisfied, turn on the organic light emitting panel and turn off the liquid crystal display panel, so as to use the organic light ...

Embodiment 3

[0078] Figure 8 It is a schematic structural diagram of a screen switching system provided by Embodiment 3 of the present invention. The system can be implemented by software and / or hardware, and any embodiment of the present invention can be executed to provide a screen switching method. The system includes:

[0079] The first display screen determination module 810 is configured to turn on the liquid crystal display panel and turn off the organic light-emitting panel, so as to use the liquid crystal display panel as the current display screen if it is determined that the first screen use condition is satisfied;

[0080] The second display screen determination module 920 is configured to turn on the organic light emitting panel and turn off the liquid crystal display panel if it is determined that the second screen use condition is satisfied, so as to use the organic light emitting panel as the current display screen.

[0081] Further, the conditions for using the first scre...

Abstract

The embodiment of the invention discloses a display device, a screen switching method and an electronic device. The display device includes an organic light emitting display panel and a liquid-crystal display panel, wherein the liquid-crystal display panel covers the organic light emitting display panel. The liquid-crystal display panel includes a bottom-layer substrate, a liquid crystal layer and an upper-layer substrate which are arranged in a stacked mode; the bottom-layer substrate is a transparent substrate, the bottom-layer substrate in the liquid-crystal display panel is abutted to a metal layer included in the organic light emitting display panel so that the metal layer can be directly used as a backlight source of the liquid-crystal display panel, and the liquid-crystal display panel further includes a linear polarizer and a wave plate, wherein the linear polarizer is located on one side, away from the liquid crystal layer, of the bottom-layer substrate, and the linear polarizer is located between the bottom-layer substrate and the wave plate. The embodiment of the invention adopts the display device formed by the organic light emitting display panel and the liquid-crystal display panel, the wave plate is arranged between the organic light emitting display panel and the liquid-crystal display panel, the requirement of the backlight source is met, the requirement for improving the display contrast is met, the requirements of users can be well met, and the user experience is enhanced.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technologies, and in particular, to a display device, a screen switching method, and electronic equipment. Background technique [0002] Organic light-emitting diode (Organic Light-Emitting Diode, OLED) is also called organic electro-laser display, organic light-emitting semiconductor. It is widely used because of its advantages such as self-illumination, wide viewing angle, low power consumption and high response speed. TN panel, full name Twisted Nematic (twisted nematic) panel, has become the most widely used entry-level LCD panel because of its low production cost. [0003] In the process of implementing the present invention, the inventors found that when the OLED is used in combination with the TN panel, the OLED can provide a backlight for the TN panel, but the cost is that the display contrast and color saturation of the OLED will be lost. Contents of the invention [0004]...
