[0025] Please refer to Figures 1 to 3 Figures 1 to 3 , which is the white balance burning device for in-vehicle display screens in the embodiments of the present utility model, including a mounting base 10, a color sensor 20, a signal processing module, and a host computer 40.
[0026] Among them: A placement position is provided on the mounting base 10. The placement position is used for placing the liquid crystal module to be adjusted. The placement position includes a supporting plate 11 and a placement notch 12 provided on the supporting plate 11. The placement notch 12 is dug on the supporting plate 11. The size of the placement notch 12 is adapted to the size of the liquid crystal module to be adjusted, so that the liquid crystal module to be adjusted can be embedded into the placement notch 12 to limit the liquid crystal module to be adjusted.
[0027] In this embodiment, the color sensor 20 is located above the placement position. The color sensor 20, the signal processing module, and the host computer 40 are electrically connected in sequence. The color sensor 20 is used to obtain the LV value of the liquid crystal module to be adjusted and the corresponding analog signals of the color coordinates of each picture. The host computer 40 is used to adjust the fixed value of the liquid crystal module to be adjusted according to the analog signal processed by the signal processing module, and to burn the adjusted fixed value into the IC register of the liquid crystal module to be adjusted.
[0028] It should be noted that the fixed value is a parameter for the human eye to adapt to brightness, also known as the gamma value, and is generally represented by a value.
[0029] In this embodiment, a receiving groove is provided on the mounting base 10. The supporting plate 11 of the placement position is slidably connected to the groove wall of the receiving groove through a sliding structure. Specifically, the sliding structure includes a slide rail and a slider. The slide rail is installed on the groove wall of the receiving groove, and the slider is connected to the side wall of the supporting plate 11. The slider is inserted into the slide rail to realize the sliding connection between the placement position and the groove wall of the receiving groove through the sliding structure.
[0030] In this embodiment, a limiting plate is connected to the side wall of the placement position. The limiting plate is in a trapezoidal structure. The area of the outer end of the limiting plate is larger than the area of its inner end in the groove. The limiting plate is used to insert into the receiving groove as the placement position moves until it abuts against the groove wall of the receiving groove. When the limiting plate abuts against the groove wall of the receiving groove, the end of the supporting plate 11 away from the opening of the receiving groove contacts the bottom of the receiving groove. It should be noted that the limiting plate is made of rubber material.
[0031] In this embodiment, a through groove 13 is formed in the mounting base 10. The through groove 13 communicates with the accommodating groove. The color sensor 20 senses the liquid crystal module to be adjusted through the through groove 13. It should be noted that the through groove 13 is located above the middle of the placing slot opening 12. The color sensor 20 is installed on the mounting base 10 through a fixing frame 50. The color sensor 20 corresponds to the central position of the liquid crystal module to be adjusted. The color sensor 20 is connected to the fixing frame 50, and the fixing frame 50 is connected to the mounting base 10.
[0032] It should be noted that the shortest straight-line distance between the color sensor 20 and the liquid crystal module to be adjusted is less than or equal to 3 mm.
[0033] In this embodiment, a cover plate 14 is provided on the mounting base 10. The cover plate 14 is used to cover a part of the through groove 13 so that when the placing position moves into the accommodating groove, the accommodating groove is in a darkroom environment, which is convenient for subsequent programming operations.
[0034] In this embodiment, the color sensor 20 is connected to a power supply through a control switch. The control switch is installed at the bottom of the accommodating groove. An abutting block is provided at the end of the placing position facing the bottom of the accommodating groove. The abutting block is used to contact the control switch as the placing position moves to turn on the control switch. It can be understood that the power cord of the color sensor 20 is connected to the control switch.
[0035] In this embodiment, the signal processing module includes a signal amplifier 31, an AD conversion circuit 32, and a signal processor 33. The color sensor 20, the signal amplifier 31, the AD conversion circuit 32, and the host computer 40 are connected in sequence. The signal processor 33 is connected to the host computer 40, and the signal processor 33 is connected to the liquid crystal module to be adjusted.
[0036] It should be noted that the color sensor 20 detects the corresponding signal of the color coordinates of the liquid crystal module to be adjusted. This signal is amplified by the signal amplifier 31, then communicated with the signal processor 33 by using the AD conversion circuit 32, and then the software in the host computer 40 calculates a fixed value that meets the requirements according to the signal and the library file of the IC register. Then the calculated signal is fed back to the signal processor 33, and the signal processor 33 executes the programming action to program the calculated fixed value into the IC register of the liquid crystal module to be adjusted.
[0037] In this embodiment, a hot-swap structure is provided on the mounting base 10. The hot-swap structure 60 is connected to the power supply. The connection end of the hot-swap structure with the liquid crystal module to be adjusted is movably connected. The hot-swap structure 60 is connected to the mounting base 10 through a rotating member. When the liquid crystal module to be adjusted is placed in the placement notch 12, the signal processor 33 is connected to the liquid crystal module to be adjusted, and the signal processor 33 is in a non-powered state. The hot-swap structure 60 rotates through the rotating member to cover the connection end of the liquid crystal module to be adjusted. At this time, the hot-swap structure 60 is turned on, and the hot-swap structure 60 transmits the power-on signal of the signal processor 33. The signal processor 33 is powered on and operates, and the signal processor 33 realizes normal signal transmission work. On the contrary, by rotating the hot-swap structure 60 away from the connection end of the liquid crystal module to be adjusted through the rotating member, the signal processor 33 is powered off to prevent damage to the liquid crystal module to be adjusted caused by hot plugging and hot unplugging. It should be noted that the hot-swap structure is a prior art and will not be elaborated here.
[0038] In specific implementation, by providing a color sensor 20, a signal processing module and a host computer 40 on the mounting base 10, a placement position is set on the mounting base 10, and a receiving groove and a through groove 13 are formed on the mounting base 10. The receiving groove is communicated with the through groove 13. The liquid crystal module to be adjusted in the placement position is slid into the receiving groove through a sliding structure, so that the color sensor 20 senses the liquid crystal module to be adjusted through the through groove 13 to obtain the corresponding analog signals of the LV value and the color coordinates of each picture of the liquid crystal module to be adjusted. Then, according to the analog signals processed by the signal processing module, the host computer 40 adjusts the fixed value of the liquid crystal module to be adjusted, and burns the adjusted fixed value into the IC register of the liquid crystal module to be adjusted. For different models of LCD displays, the appropriate fixed value can be dynamically adjusted to meet the corresponding burning conditions. A single burning device can complete the burning work of different models of LCD displays, expanding the application range and also helping to save production costs.
[0039] It should be noted that the above implementation process is only to illustrate the feasibility of the present application, but this does not mean that the on-vehicle display white balance burning device of the present application has only the above-mentioned single implementation process. On the contrary, as long as the on-vehicle display white balance burning device of the present application can be implemented, it can be included in the feasible implementation solutions of the present application.

In this specification, the schematic expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.
[0041] The above-described embodiments merely represent several implementation manners of the present utility model. The descriptions are relatively specific and detailed, but should not be construed as limiting the scope of the patent of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several variations and improvements can still be made, and these all belong to the protection scope of the present utility model.
