Solution Overview
Problem
Existing 2D/3D switchable display panels suffer from poor display effects in 2D mode due to lower image sampling rates compared to LCD panels when operating in 2D/3D display mode.
Innovation Solution
A 2D/3D switchable display panel comprising a self-luminescent OLED panel and an LCD panel without a color resist layer, where the OLED panel acts as a backlight source in 2D mode and the LCD panel functions as a grating or display main body in 3D mode, ensuring higher image sampling rates and reduced thickness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If OLED display panel is used to replace LCD panel in optical barrier type 3D product, then thickness is reduced, but display effect in 2D mode deteriorates due to lower image sampling rate
Solution Approach 1:
The display system is segmented into two distinct panels: an OLED display panel for 3D display function and an LCD panel for 2D display function. This segmentation allows each panel to be optimized for its specific function, with the OLED panel providing thin-profile 3D capability and the LCD panel delivering high-resolution 2D images through its superior pixel density
Solution Approach 2:
The display device achieves multi-functionality by combining OLED and LCD panels that can operate in different modes. The system universally supports both 2D and 3D display modes, where the OLED panel serves as the primary display in 3D mode and the LCD panel serves as the primary display in 2D mode, allowing the device to adapt to different viewing requirements
2Illumination intensity
If separate backlight source module is provided in LCD panel, then display brightness is improved, but device complexity and thickness increase
Solution Approach 1:
The OLED display panel inherently emits light, eliminating the need for a separate backlight source module. This merging of display and illumination functions into a single component reduces structural complexity and thickness while maintaining adequate display brightness for both 2D and 3D modes
Solution Approach 2:
The backlight source module is extracted from the system by utilizing the self-luminescent property of the OLED panel. This extraction removes the unnecessary backlight component and its associated control structures, simplifying the overall device architecture while the OLED's intrinsic light emission provides sufficient illumination
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration achieves better display effects in 2D mode with higher image sampling rates and reduced thickness by optimizing the roles of OLED and LCD panels, eliminating the need for a separate backlight source and reducing power consumption.
Implementation Method 1
an OLED display panel which is self-luminescent
Implementation Method 2
by forming stripe-shaped electrode strips on both upper and lower substrates of the LCD panel, with a working principle being in that, upon implementing 3D display, the liquid crystal grating is electrified; and since liquid crystal molecules between the stripe-shaped electrode strips on the upper and lower substrates are twisted, then light is inhibited from passing therethrough completely

AI summary
The embodiment of the present application discloses a 2D/3D switchable display panel, and a display method and a display device thereof, so as to solve the problem of poor display effect in 2D display mode of existing 2D/3D display panel. The 2D/3D switchable display panel includes a self-luminescent OLED display panel and a LCD panel provided with no color resistance layer, which LCD display panel is disposed on the display side of the OLED display panel. The OLED display panel is used for display images when the 2D/3D switchable display panel operates in 3D display mode while functions as a backlight source module when the 2D/3D switchable display panel operates in 2D display mode; whereas the LCD display panel functions as a grating when the 2D/3D switchable display panel operates in 3D display mode while displays images when the 2D/3D switchable display panel operates in 2D display mode.
