[0030] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0031] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0032] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it an embodiment that is mutually exclusive with other embodiments, either individually or selectively.

[0033] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0034] Example 1, reference Figure 1 - Figure 4 , which is the first embodiment of the present invention, provides a car luminous front windshield and a control method thereof, the device comprising: a fixed connection unit 100, comprising a fixed frame 101, and a fixed clamping angle 102 arranged on the fixed frame 101, the fixed frame 101 is used to support the entire windshield, and the fixed clamping angle 102 is used to fix the entire glass;

[0035] The integrated unit 200 includes an integrated component 201 disposed inside the fixed frame 101, which is mounted on the fixed frame 101 through a fixed clamping angle 102, and is directly assembled and produced during production to form an integral body; and

[0036] The display unit 300 includes a display component 301 disposed inside the fixed frame 101, and a wiring angle 302 disposed on the display component 301, and the wiring angle 302 is connected to the fixed frame 101. The speed of the vehicle and the surrounding conditions are displayed through the display component 301, and the wiring angle 302 at the bottom is used to install the display component 301 in a wiring manner so as not to affect the light transmittance of the glass.

[0037] Among them, the integrated component 201 includes a transparent tempered glass 201a arranged inside the fixed frame 101, and the transparent tempered glass 201a is connected to the fixed corner 102. The transparent tempered glass 201a at the top of the fixed frame 101 is used for the first layer of fixed protection and is fixed to the fixed corner 102.

[0038] Furthermore, a PVB film layer 201b is provided at one end of the transparent tempered glass 201a, a fixed film corner 201e is provided on the PVB film layer 201b, and the fixed film corner 201e is connected to the fixed frame 101. By fixing the PVB film layer 201b and the fixed film corner 201e under the fixing angle 102, the strength of the glass is enhanced and it is prevented from falling when broken.

[0039] Furthermore, a high-transmittance glass 201c is provided at one end of the PVB film layer 201b, and a transparent tempered glass 2 201d is provided at one end of the high-transmittance glass 201c, and the transparent tempered glass 2 201d is connected to the fixed frame 101. The high-transmittance glass 201c at the bottom of the PVB film layer 201b increases the light transmittance of the front windshield, thereby not affecting the driver's observation of the surrounding environment through the glass, and the transparent tempered glass 2 201d at the bottom forms a complete whole with the transparent tempered glass 1 201a.

[0040] During use, when the front windshield is produced and assembled, the transparent tempered glass 1 201a and the transparent tempered glass 2 201d are placed in a cleaning machine, washed and dried, and then transferred to a laminating room where the temperature and humidity are controlled. Next, the cut PVB film layer 201b is placed on the glass surface. The PVB film layer 201b needs to be placed flat to ensure that there are no wrinkles. The OLED base layer 301a is placed on top of the PVB film layer 201b using a fixture for laminating. The laminating process must be performed in a dust-free workshop. Then, another layer of PVB film layer 201b is placed on the OLED base layer 301a. The PVB film layer needs to be placed flat to ensure that there are no wrinkles. Finally, the transparent tempered glass 2 201d is placed on the film to complete a piece of glass.

[0041] When routing and using the equipment, the OLED base layer 301a is placed above the PVB film layer 201b. When the pieces are assembled, the reserved installation port for installing the display unit 300 is connected to the fixed frame 101 through the wiring module 301d, so that the wiring can be arranged along the fixed frame 101 so that the OLED base layer 301a can be connected to the vehicle's large screen for control. At the same time, the external light source can be monitored through the display component 301 to change the brightness of the OLED base layer 301a. In addition, the routing of the integrated unit 200 is all arranged along the fixed frame 101 according to the wiring module 301d, so that the driver's observation of the outside through the glass is not affected, and the front windshield can also be beautified.

[0042] Example 2, reference Figure 1 - Figure 5 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: the display component 301 includes an OLED base layer 301a arranged at one end of a high-transmittance glass 201c, an OLED fixing frame 301b arranged on the OLED base layer 301a, an OLED pixel module 301c arranged on the OLED fixing frame 301b, and a steam vent 301f arranged at one end of the OLED fixing frame 301b. The high-transmittance glass 201c can ensure the light transmittance of the front windshield. The OLED base layer 301a and the OLED pixel module 301c are connected to perform imaging on the windshield, integrating the function of the instrument display into the front windshield, solving the space occupation problem of current HUD projection components, and optimizing the comfortable space of the driving position.

[0043] Compared with Example 1, further, a wiring module 301d is provided on the steam port 301f, a photosensor 301e is provided at the other end of the wiring module 301d, and the photosensor 301e is connected to the fixed frame 101. The steam and water vapor inside the high-transmittance glass 201c can be discharged through the steam port 301f, and the wiring module 301d is connected through the steam port 301f, so that the wiring can be routed through the wiring module 301d at the bottom of the fixed frame 101 to ensure the overall light transmittance of the glass.

[0044] During use, when working imaging is performed, the driver controls the vehicle screen to control the OLED pixel module 301c inside the OLED base layer 301a to perform imaging, and each OLED pixel module 301c on the OLED base layer 301a can emit light independently, so that the real-time picture can be dynamically displayed. Under the premise of meeting the resolution used, a reasonable spacing is set between each pixel point, so that the road information in front of the vehicle and the display picture of the glass can be observed by the driver, and the external light source is monitored by the photosensitive sensor 301e, and the data is collected and transmitted to the inside of the vehicle, and the OLED pixel module 301c is connected through the steam port 301f, so that each OLED pixel module 301 c can adaptively adjust the brightness according to the intensity of the light source monitored by the photosensitive sensor 301e to prevent the external light source from being too bright and the driver from not being able to see clearly. Again, an outlet is left between the steam port 301f and the fixed frame 101, so that the OLED base layer 301a can adjust the internal OLED pixel module 301c, and the mist is exhausted to prevent heat dissipation. The car computer chip transmits the real-time displayed image to the screen controller, and the screen controller independently controls the luminous state and luminous color of each OLED pixel module 301c. Due to the luminous characteristics of the OLED pixel module 301c, the pixels in the non-luminous area are transparent, thereby not affecting the driver's observation of vehicle information.

[0045] The remaining structures are the same as those of Example 1.

[0046] Example 3, reference Figure 1 - Figure 6 , which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that: the windshield as a whole includes five layers, and transparent tempered glass 1 201a and transparent tempered glass 2 201d are located on the surface layer and the innermost layer, and the middle is composed of an integrated component 201 and a display component 301. The display component 301 can be changed as needed to achieve display areas with different luminous ranges.

[0047] Compared with Example 2, further, a transparent tempered glass 201a is used as a surface layer of glass with high light transmittance.

[0048] Preferably, the PVB film layer 201b is set as a PVB film polymer layer. When the glass is broken, the PVB film will stick the glass fragments together.

[0049] Preferably, the display component 301 is composed of an OLED base layer 301a of transparent conductive film arranged at a fixed interval;

[0050] The external light source is monitored by the photosensitive sensor 301e, and the brightness of the OLED pixel module 301c is adjusted according to the strength of the external light source, and the wiring module 301d is used to connect the wiring at the bottom of the glass;

[0051] The high light transmittance glass 201c uses the same high light transmittance glass as the transparent tempered glass 201a, which can not only improve the safety level of the vehicle, but also protect the pixels in the light-emitting area from being damaged;

[0052] The display control of the luminous front windshield is integrated by the large central screen on the vehicle. The vehicle computer chip transmits the real-time display image to the screen controller, which then independently controls the luminous state and luminous color of each pixel point, and monitors the light source through the photosensitive sensor 301e, thereby adjusting the brightness of the OLED pixel module 301c.

[0053] During use, when the front windshield is broken for safety protection, the internal PVB film layer 201b is a PVB film polymer layer. When the glass is broken, the PVB film inside the PVB film layer 201b will stick the glass fragments together to prevent the glass fragments from scattering and injuring people, and the fixed film corner 201e will fix the broken glass, so that after the glass is broken as a whole, it can also be kept as a whole to prevent the glass fragments from scattering and injuring people. In addition, the surface transparent tempered glass 201a and the inner transparent tempered glass 2 201d of the windshield are both made of high-transmittance tempered glass to ensure the glass strength of the front windshield, improve the safety level, and provide safety protection for the driver inside the car.

[0054] The OLED pixel module 301c is connected via the steam port 301f, so that each OLED pixel module 301c can adaptively adjust the brightness according to the intensity of the light source monitored by the photosensor 301e to prevent the external light source from being too bright for the driver to see clearly. The real-time displayed image is transmitted to the screen controller via the vehicle computer chip, and the screen controller independently controls the luminous state and luminous color of each pixel point, and monitors the light source via the photosensor 301e, thereby adjusting the brightness of the OLED pixel module 301c, thereby preventing the driver from visual fatigue by adjusting the brightness of the OLED display.

[0055] The remaining structure is the same as that of Example 2.
