In the third state, it is used to control the first object in the display pixel signal to present a first depth of field and the second object to present a second depth of field. The first depth of field is different from the second depth of field, so as to realize 3D depth of field display, make the picture more immersive, and improve the user experience.

[0048] In this embodiment, a plurality of liquid crystals 204 and electrode layers 205 of the plurality of liquid crystals 204 serve as a light control layer of the display mode switching module 20. Each driving module corresponds to a liquid crystal 204 and is used to drive the liquid crystal 204.

[0049] In this embodiment, the driving module may be a field effect transistor (MOSFET).

[0050] In this embodiment, if Figure 2 As shown, the display mode switching module 20 further includes a second glass substrate 203, and a plurality of driving modules 201 are disposed on the second glass substrate 203. The driving module 201 further includes a passivation layer 2015, an isolation layer 2016, an interlayer dielectric layer 2017, and a flat layer 2018. The passivation layer 2015 is disposed on the second glass substrate 203, the semiconductor layer 2011 is disposed on the passivation layer 2015, the isolation layer 2016 is disposed between the semiconductor layers 2011, the interlayer dielectric layer 2017 is disposed between the gate electrodes 2013, and the flat layer 2018 is disposed on the interlayer dielectric layer 2017. The electrode layer 205 is disposed on the flat layer 2018, and a plurality of liquid crystals 204 are disposed on the electrode layer 205. The display mode switching module 20 further includes a nanoimprint layer 206, which is disposed on the flat layer 2018 and surrounds the plurality of liquid crystals 204.

[0051] In this embodiment, when multiple liquid crystals are controlled to deflect 0° by multiple driving modules, multiple liquid crystals transmit display pixel signals, and the display mode switching module 20 has a first state; when multiple liquid crystals are controlled to deflect 90° by multiple driving modules, multiple liquid crystals refract display pixel signals, and the display mode switching module 20 has a second state; when the first part of the liquid crystals are controlled to deflect 90° by multiple driving modules, and the second part of the liquid crystals are controlled to deflect an angle between 0°-90°, the display mode switching module has a third state. Or when the liquid crystal corresponding to the display pixel signal corresponding to the first object is controlled to deflect at a first angle by multiple driving modules, and the liquid crystal corresponding to the display pixel signal corresponding to the second object is controlled to deflect at a second angle, the display mode switching module has a third state, and the first angle is different from the second angle, and the first angle and the second angle are angles between 0°-90°.

[0052] In this embodiment, by setting multiple liquid crystals in the light control layer of the display mode switching module, and setting multiple driving modules corresponding to the multiple liquid crystals, the deflection control of each liquid crystal can be achieved by separately controlling each driving module, and the liquid crystal control at the pixel level can be achieved to realize 3D depth of field display.

[0053] In an optional embodiment, in the first state, multiple driving modules 201 are controlled to have the same first voltage, so that the display pixel signal is directly output through the display mode switching module 20 to present a 2D display mode; in the second state, multiple driving modules 201 are controlled to have the same second voltage, so that the display pixel signal is output through the display mode switching module 20 based on refraction to present a 3D display mode; in the third state, multiple driving modules 201 are controlled to have different third voltages, so that the display pixel signal corresponding to the first object in the display pixel signal presents a first depth of field based on the first refraction through the display mode switching module 20, and the display pixel signal corresponding to the second object in the display pixel signal presents a second depth of field based on the second refraction through the display mode switching module 20, and the first refraction is different from the second refraction.

[0054] In this embodiment, the refraction angle and / or refractive index of the first refraction and the second refraction are different. The first refraction may be such that the display pixel signal of the first object is refracted to the left eye and the right eye of the user, so that the display pixel signal corresponding to the first object has no crosstalk; the second refraction may be such that the display pixel signal of the second object is refracted to the left eye and the right eye of the user, so that the display pixel signal corresponding to the second object generates crosstalk.

[0055] In this embodiment, the first refraction may be such that the display pixel signal of the first object is refracted to the left eye and the right eye of the user, so that the display pixel signal corresponding to the first object produces a first degree of crosstalk; the second refraction may be such that the display pixel signal of the second object is refracted to the left eye and the right eye of the user, so that the display pixel signal corresponding to the second object produces a second degree of crosstalk, and the first crosstalk degree is different from the second crosstalk degree, that is, different depths of field are produced for different objects.

[0056] In this embodiment, when the plurality of driving modules have the same first voltage, the display mode switching module transparently transmits the display pixel signals of each pixel unit, so that the display pixel signals are directly output through the display mode switching module 20 to present a 2D display mode.

[0057] When multiple driving modules have the same second voltage, the display mode switching module refracts the display pixel signals of each pixel unit so that the display pixel signals are refracted to the user's left eye and right eye without generating crosstalk, so that the display pixel signals are output through the display mode switching module to present a 3D display mode.

[0058] When multiple driving modules have different third voltages, the display mode switching module performs a first refraction on the display pixel signal corresponding to the first object and a second refraction on the display pixel signal corresponding to the second object, so that the display pixel signal corresponding to the first object and the display pixel signal of the second object generate different degrees of crosstalk when refracted to the left and right eyes of the user, thereby presenting a first depth of field and a second depth of field.

[0059] In this embodiment, by changing the voltages of multiple driving modules, the state of the display mode switching module can be changed in a simple manner.

[0060] In an optional embodiment, in the third state, multiple driving modules are controlled to have different third voltages, including controlling a first part of driving modules of display pixel signals corresponding to a first object among the multiple driving modules to have a fourth voltage, and controlling a second part of driving modules of display pixel signals corresponding to a second object among the multiple driving modules to have a fifth voltage; the fourth voltage is different from the fifth voltage.

[0061] In this embodiment, the fourth voltage may be the same as the second voltage, and the fifth voltage may be 1 / 3 to 2 / 3 of the fourth voltage.

[0062] In this embodiment, the fourth voltage may be 1 / 3 to 2 / 3 of the second voltage, and the fifth voltage may be 1 / 3 to 2 / 3 of the second voltage, but the two are different.

[0063] In a specific implementation, the first part of the driving modules corresponding to the display pixel signals of the first object among the multiple driving modules can be controlled to have a fourth voltage, so that the display pixel signals corresponding to the first object are refracted to the left eye and the right eye of the user, presenting a first depth of field, or realizing clear display of the first object. The second part of the driving modules corresponding to the display pixel signals of the second object among the multiple driving modules can be controlled to have a fifth voltage, so that the display pixel signals corresponding to the second object are refracted to the left eye and the right eye of the user, presenting a second depth of field, or realizing blurred display of the first object.

[0064] In this embodiment, 3D depth of field display can be achieved by controlling the first part of the driving modules corresponding to the display pixel signals of the first object among the multiple driving modules to have a fourth voltage, and controlling the second part of the driving modules corresponding to the display pixel signals of the second object among the multiple driving modules to have a fifth voltage.

[0065] The present application also provides a naked eye 3D display device, such as Figure 3 As shown, including:

[0066] The display screen 31 includes a 2D display module, which includes multiple pixel units and is used to provide display pixel signals; a display mode switching module is arranged on the light-emitting side of the 2D display module, and the display mode switching module includes multiple independent driving modules corresponding to the multiple pixel units; wherein the display mode switching module can be controlled to have a first state, a second state and a third state, in the first state, it is used to control the display pixel signal to present a 2D display mode, in the second state, it is used to control the display pixel signal to present a 3D display mode, and in the third state, it is used to control the first object in the display pixel signal to present a first depth of field, and the second object to present a second depth of field, and the first depth of field is different from the second depth of field.

[0067] The sight tracking module 32 is used to obtain the sight position of the user.

[0068] The control module 33 is used to control the display mode switching module to be in the first state, the second state or the third state based on the sight line position and the display mode switching signal.

[0069] In this embodiment, the specific explanation of the 2D display module and the display mode switching module involved in the display screen can be found in the explanation of the naked-eye 3D display module in the above embodiment, which will not be repeated here.

[0070] In this embodiment, the sight tracking module can determine the eye viewing angle and the distance between the eye and the display screen, etc. The sight position includes the eye viewing angle and the distance between the eye and the display screen.

[0071] In this embodiment, the state that the display mode switching module needs to adjust can be determined based on the display mode switching signal, such as the first state, the second state or the third state, so that it can be determined whether the multiple driving modules need to have the same first voltage, the same second voltage or different third voltages. Based on the line of sight position, the target driving module corresponding to the line of sight position or the depth of field corresponding to the line of sight position can be determined, so that when the display mode switching module is controlled to be in the third state, when multiple driving modules are controlled, the voltage of the target driving module can be set to be different from the voltage of other driving modules, or the third voltage of multiple driving modules can be set according to the depth of field corresponding to the line of sight position, so that the first object in the display pixel signal presents a first depth of field, and the second object presents a second depth of field.

[0072] The naked-eye 3D display device provided by the embodiment of the present application is provided with a display mode switching module on the light-emitting side of the 2D display module, and a plurality of independent driving modules corresponding to a plurality of pixel units are provided in the display mode switching module, so that each driving module can be controlled separately, so that the naked-eye 3D display module can realize pixel-level display pixel signal control, thereby making the display mode switching module have a first state, a second state and a third state. In the first state, it is used to control the display pixel signal to present a 2D display mode. In the second state, it is used to control the display pixel signal to present a 3D display mode. In the third state, it is used to control the first object in the display pixel signal to present a first depth of field and the second object to present a second depth of field. The first depth of field is different from the second depth of field, thereby realizing 3D depth of field display, making the picture more immersive and improving the user experience.

[0073] In an optional embodiment, the control module 33 is used to control multiple driving modules to have the same first voltage to control the display mode switching module to be in a first state if the display mode switching signal is a 2D display mode switching signal; if the display mode switching signal is a 3D display mode switching signal, control multiple driving modules to have the same second voltage to control the display mode switching module to be in a second state; if the display mode switching signal is a depth of field display mode switching signal, determine the target driving module based on the line of sight position, and control the target driving module to have a third voltage to control the display mode switching module to be in a third state.

[0074] In this embodiment, when the plurality of driving modules have the same first voltage, the display mode switching module transparently transmits the display pixel signals of each pixel unit, so that the display pixel signals are directly output through the display mode switching module 20 to present a 2D display mode.

[0075] When multiple driving modules have the same second voltage, the display mode switching module refracts the display pixel signals of each pixel unit so that the display pixel signals are refracted to the user's left eye and right eye without generating crosstalk, so that the display pixel signals are output through the display mode switching module to present a 3D display mode.

[0076] In this embodiment, based on the sight line position, the target pixel unit corresponding to the sight line position can be determined, and based on the target pixel unit, the corresponding target driving module can be determined, thereby determining the target driving module corresponding to the sight line position. Therefore, when the display mode switching module is controlled to be in the third state, the target driving module can be set to have a third voltage, so that the display pixel signal corresponding to the first object in the display pixel signal presents a first depth of field based on the first refraction through the display mode switching module, and the display pixel signal corresponding to the second object in the display pixel signal presents a second depth of field based on the second refraction through the display mode switching module, and the first refraction is different from the second refraction. Specifically, the display mode switching module performs a first refraction on the display pixel signal corresponding to the first object and a second refraction on the display pixel signal corresponding to the second object, so that the display pixel signal corresponding to the first object and the display pixel signal of the second object generate different degrees of crosstalk when refracted to the left and right eyes of the user, thereby presenting the first depth of field and the second depth of field. The refraction angle and / or refractive index of the first refraction and the second refraction are different.

[0077] In this embodiment, by changing the voltages of multiple driving modules, the state of the display mode switching module can be changed in a simple manner.

[0078] The embodiment of the present application also provides a naked-eye 3D image display method, which is applied to a naked-eye 3D display device, wherein the naked-eye 3D display device includes a display screen, the display screen includes a 2D display module, the 2D display module includes a plurality of pixel units, and is used to provide a display pixel signal; a display mode switching module is arranged on the light-emitting side of the 2D display module, and the display mode switching module includes a plurality of independent driving modules corresponding to the plurality of pixel units; wherein the display mode switching module can be controlled to have a first state, a second state, and a third state, wherein in the first state, it is used to control the display pixel signal to present a 2D display mode, and in the second state, it is used to control the display pixel signal to present a 3D display mode, and in the third state, it is used to control the first object in the display pixel signal to present a first depth of field, and the second object to present a second depth of field, and the first depth of field is different from the second depth of field; the naked-eye 3D image display method is as follows Figure 4 As shown, including:

[0082] In this embodiment, a sight tracking module may be used to obtain the sight position of the user, which includes the eye viewing angle and the distance between the eye and the display screen.

[0083] In this embodiment, the state that the display mode switching module needs to adjust can be determined based on the display mode switching signal, such as the first state, the second state or the third state, so that it can be determined whether the multiple driving modules need to have the same first voltage, the same second voltage or different third voltages. Based on the line of sight position, the target driving module corresponding to the line of sight position or the depth of field corresponding to the line of sight position can be determined, so that when the display mode switching module is controlled to be in the third state, when multiple driving modules are controlled, the voltage of the target driving module can be set to be different from the voltage of other driving modules, or the third voltage of multiple driving modules can be set according to the depth of field corresponding to the line of sight position, so that the first object in the display pixel signal presents a first depth of field, and the second object presents a second depth of field.

[0084] The naked-eye 3D image display method provided by the embodiment of the present application is provided with a display mode switching module on the light-emitting side of the 2D display module, and a plurality of independent driving modules corresponding to a plurality of pixel units are provided in the display mode switching module, so that each driving module can be controlled separately, so that the naked-eye 3D display module realizes pixel-level display pixel signal control, thereby making the display mode switching module have a first state, a second state and a third state. In the first state, it is used to control the display pixel signal to present a 2D display mode. In the second state, it is used to control the display pixel signal to present a 3D display mode. In the third state, it is used to control the first object in the display pixel signal to present a first depth of field and the second object to present a second depth of field. The first depth of field is different from the second depth of field, thereby realizing 3D depth of field display, making the picture more immersive and improving the user experience.

[0085] In an optional embodiment, the naked eye 3D image display method further includes:

[0086] In the third state: if the line of sight is at the first position, the first object in the display pixel signal is controlled to present a first depth of field, and the second object presents a second depth of field; if the line of sight is at the second position, the first object in the display pixel signal is controlled to present a third depth of field, and the second object presents a fourth depth of field; the first depth of field is different from the third depth of field, the second depth of field is different from the fourth depth of field, and the first position is different from the second position.

[0087] In this embodiment, at different sight line positions, the depth of field presented by the first object or the second object will change.

[0088] In this embodiment, by making the depth of field presented by the first object or the second object different at different sight lines, it is possible to achieve that the 3D depth of field display changes with the user's position, thereby improving the user experience.

[0089] In an optional embodiment, in step S403, controlling the display mode switching module to be in the first state, the second state or the third state based on the sight line position and the display mode switching signal includes:

[0090] If the display mode switching signal is a 2D display mode switching signal, multiple driving modules are controlled to have the same first voltage to control the display mode switching module to be in the first state; if the display mode switching signal is a 3D display mode switching signal, multiple driving modules are controlled to have the same second voltage to control the display mode switching module to be in the second state; if the display mode switching signal is a depth of field display mode switching signal, the target driving module is determined based on the line of sight position, and the target driving module is controlled to have a third voltage to control the display mode switching module to be in the third state.

[0091] In this embodiment, when the plurality of driving modules have the same first voltage, the display mode switching module transparently transmits the display pixel signals of each pixel unit, so that the display pixel signals are directly output through the display mode switching module 20 to present a 2D display mode.

[0092] When multiple driving modules have the same second voltage, the display mode switching module refracts the display pixel signals of each pixel unit so that the display pixel signals are refracted to the user's left eye and right eye without generating crosstalk, so that the display pixel signals are output through the display mode switching module to present a 3D display mode.

[0093] In this embodiment, based on the sight line position, the target pixel unit corresponding to the sight line position can be determined, and based on the target pixel unit, the corresponding target driving module can be determined, thereby determining the target driving module corresponding to the sight line position. Therefore, when the display mode switching module is controlled to be in the third state, the target driving module can be set to have a third voltage, so that the display pixel signal corresponding to the first object in the display pixel signal presents a first depth of field based on the first refraction through the display mode switching module, and the display pixel signal corresponding to the second object in the display pixel signal presents a second depth of field based on the second refraction through the display mode switching module, and the first refraction is different from the second refraction. Specifically, the display mode switching module performs a first refraction on the display pixel signal corresponding to the first object and a second refraction on the display pixel signal corresponding to the second object, so that the display pixel signal corresponding to the first object and the display pixel signal of the second object generate different degrees of crosstalk when refracted to the left and right eyes of the user, thereby presenting the first depth of field and the second depth of field. The refraction angle and / or refractive index of the first refraction and the second refraction are different.

[0094] In this embodiment, by changing the voltages of multiple driving modules, the state of the display mode switching module can be changed in a simple manner.

[0095] In an optional embodiment, controlling the target driving module to have a third voltage to control the display mode switching module to be in a third state includes:

[0096] The first part of the driving module corresponding to the display pixel signal of the first object in the control target driving module has a fourth voltage, and the second part of the driving module corresponding to the display pixel signal of the second object in the control target driving module has a fifth voltage; the fourth voltage is different from the fifth voltage.

[0097] In this embodiment, the fourth voltage may be the same as the second voltage, and the fifth voltage may be 1 / 3 to 2 / 3 of the fourth voltage.

[0098] In this embodiment, the fourth voltage may be 1 / 3 to 2 / 3 of the second voltage, and the fifth voltage may be 1 / 3 to 2 / 3 of the second voltage, but the two are different.

[0099] In a specific implementation, the first part of the target driving module corresponding to the display pixel signal of the first object can be controlled to have a fourth voltage, so that the display pixel signal corresponding to the first object is refracted to the left eye and the right eye of the user, presenting a first depth of field. The second part of the target driving module corresponding to the display pixel signal of the second object can be controlled to have a fifth voltage, so that the display pixel signal corresponding to the second object is refracted to the left eye and the right eye of the user, presenting a second depth of field.

[0100] In this embodiment, 3D depth of field display can be achieved by controlling the first part of the target driving module corresponding to the display pixel signal of the first object to have a fourth voltage, and controlling the second part of the driving module corresponding to the display pixel signal of the second object in multiple driving modules to have a fifth voltage.
