no. 1 approach

[0026] see figure 1 , the curved display device 100 provided by the first embodiment of the present invention includes a flexible display panel 10 and a curvature-adjusting backplane 20 .

[0027] The flexible display panel 10 is a non-rigid display panel, which has a certain degree of flexibility and can produce a proper amount of deformation when subjected to an external force. The flexible display panel 10 is preferably a display panel that can emit light by itself without a backlight module, such as a thinned organic light emitting diode (Active Matrix OLED, AMOLED) display panel. Specifically, see figure 2 The flexible display panel 10 includes a thin film transistor (Thin Film Transistor, TFT) array flexible substrate 11, and an anode pixel electrode layer 12 and a hole injection layer 13 sequentially arranged on the TFT array flexible substrate 11 from bottom to top. , a hole transport layer 14, an OLED light-emitting layer 15, an electron transport layer 16, an elec...

no. 2 approach

[0033] see Figure 5 The curved display device 200 provided by the embodiment of the present invention includes a flexible display panel 30 , a curvature-adjusting backplane 40 , and a heat dissipation plate 50 disposed between the display panel 30 and the curvature-adjusting backplane 40 .

[0034] The flexible display panel 30 is a non-rigid display panel, which has a certain degree of flexibility, and can produce a proper amount of deformation when subjected to an external force. The flexible display panel 30 is preferably a display panel that can emit light by itself and does not need a backlight module, such as a thinned organic light emitting diode (Active Matrix OLED, AMOLED) display panel. Specifically, see Image 6 The flexible display panel 30 includes a thin film transistor (Thin Film Transistor, TFT) array flexible substrate 31, and an anode pixel electrode layer 32 and a hole injection layer 33 sequentially arranged on the TFT array flexible substrate 31 from bot...

Abstract

The invention provides a curved surface display device. The curved surface display device comprises a flexible display panel and a curvature adjusting back panel. The curvature adjusting back panel is used for supporting and fixing the flexible display panel. The curvature adjusting back panel comprises a plurality of strip-shaped alloy parts and a curvature driving unit, and the alloy parts are connected in sequence. The curvature driving unit is used for driving the alloy parts to be deformed so as to change the curvature factor of the curvature factor adjusting back panel.

Description

technical field [0001] The invention relates to the display field, in particular to a curved display device. Background technique [0002] With the continuous development of display technology, people have higher and higher visual requirements for display products. Curved display devices (such as curved TVs, curved displays, etc.) have gradually become a development trend because they can provide wider-angle image information. [0003] In the process of manufacturing a display device in the prior art, the display panel is pre-bent into a certain radian through a specific process, and then the curved display panel is cured by using a backlight module (including: a backplane and a plastic frame matching the backplane). fixed to form a curved display device. However, due to the fixed degree of curvature of the existing curved display panel, the visible range it can provide is also fixed, so that the display effect of the curved display device is limited and cannot meet the div...
