[0002] With the evolution of intelligent automobile technology, some on-board instruments usually divide the first display area of ​​the on-board instrument into two or three different display screens in order to make economical large-size display screens. Instruments composed of TFT and TBN are widely used in the automotive industry.

[0003] The TBN and TFT combination screen instrument in the prior art is mainly composed of a TBN display screen and a TFT display screen. The TFT display screen is directly attached to the back of the TBN display screen. When the TFT display screen needs to be lit up for display, the first display area corresponding to the TBN display screen and the TFT display screen is also lit up for the display light of the TFT display screen to pass through.

[0004] However, the existing TBN and TFT combination screen instrument directly adheres the TFT display screen to the back of the TBN display screen, which will cause the overall thickness of the vehicle-mounted instrument to be larger. Utility Model Content

[0010] Furthermore, the first display screen has two first display areas, and the avoidance area and the second display screen are located between the two first display areas.

[0011] Furthermore, the avoidance area is a hollow structure, and the first lower substrate includes two substrate parts corresponding to the two first display areas respectively, and two substrate connecting parts connecting the two substrate parts, and the two substrate parts and the two substrate connecting parts are connected in sequence and surround the avoidance area.

[0012] Furthermore, the avoidance area is a partition structure, and the first lower substrate includes two substrate parts corresponding to the two first display areas respectively, and the two substrate parts are disconnected and separated by the avoidance area.

[0013] Furthermore, the first display screen is also bound to a first circuit board, and the second display screen is also bound to a second circuit board, and the binding positions between the first circuit board and the second circuit board are on different sides.

[0014] Furthermore, the first display screen also includes a first upper polarizer and a first lower polarizer, the first upper polarizer is attached to the surface of the first upper substrate facing away from the first lower substrate, and the first lower polarizer is attached to the surface of the first lower substrate facing away from the first upper substrate.

[0015] Furthermore, the second display screen includes a second upper substrate and a second lower substrate that are relatively attached to each other, and a second display area formed between the second upper substrate and the second lower substrate.

[0016] Furthermore, the second display screen also includes a second upper polarizer and a second lower polarizer, the second upper polarizer is attached to the surface of the second upper substrate facing away from the second lower substrate, and the second lower polarizer is attached to the surface of the second lower substrate facing away from the second upper substrate.

[0031] The second display screen 2 is disposed in the avoidance area 141 of the first lower substrate 13 and is attached to the first upper substrate 12 .

[0032] The vehicle-mounted instrument of the utility model is formed by combining a first display screen 1 and a second display screen 2, and an avoidance area 141 is opened on the first lower substrate 13 of the first display screen 1, so that the second display screen 2 is arranged in the avoidance area 141 of the first lower substrate 13 and is bonded and fixed to the first upper substrate 12 of the first display screen 1, and finally a thinned structure of the vehicle-mounted instrument is realized. The overall thickness of the vehicle-mounted instrument is less than the sum of the thicknesses of the first display screen 1 and the second display screen 2, that is, the vehicle-mounted instrument reduces the thickness of one substrate.

[0033] In this embodiment, the first display screen 1 has two first display areas 10 , and the avoidance area 141 and the second display screen 2 are located between the two first display areas 10 .

[0034] The first display screen 1 is also bound to a first circuit board 15 , and the second display screen 2 is also bound to a second circuit board 25 . The first circuit board 15 and the second circuit board 25 are bound at different sides to avoid mutual interference between the first circuit board 15 and the second circuit board 25 .

[0035] In this embodiment, both the first circuit board 15 and the second circuit board 25 are flexible circuit boards, so that the first circuit board 15 and the second circuit board 25 can be bent and deformed to a certain extent when connected and assembled with external devices.

[0036] Specifically, the two first display areas 10 are respectively located on the left and right sides of the avoidance area 141, and the binding positions of the first circuit board 15 and the second circuit board 25 are respectively located on the upper and lower sides of the vehicle instrument thinning structure.

[0037] The first display screen 1 also includes a first upper polarizer 11 and a first lower polarizer 14. The first upper polarizer 11 is attached to the surface of the first upper substrate 12 on the side facing away from the first lower substrate 13, and the first lower polarizer 14 is attached to the surface of the first lower substrate 13 on the side facing away from the first upper substrate 12; the first lower polarizer 14 is also provided with an avoidance structure corresponding to the avoidance area 141 of the first lower substrate 13.

[0041] As an optimization solution of the first embodiment, in this embodiment, if Figure 3 As shown, the avoidance area 141 is a hollow structure, that is, the avoidance area 141 does not completely disconnect the first lower substrate 14. The first lower substrate 14 includes two substrate portions 142 corresponding to the two first display areas 10 respectively, and two substrate connecting portions 143 connecting the two substrate portions 142. The two substrate portions 142 and the two substrate connecting portions 143 are sequentially connected and surround the avoidance area 141.

[0042] The first lower substrate 14 can be made of a large substrate, and then a grooving method such as wet etching or CNC grinding is used to remove a portion of the large substrate corresponding to the avoidance area 141 to finally form the first lower substrate 14 . Embodiment 3

[0043] As an optimization solution of the first embodiment, in this embodiment, if Figure 4 As shown, the avoidance region 141 is a partition structure, that is, the avoidance region 141 completely separates the first lower substrate 14. The first lower substrate 14 includes two substrate portions 142 corresponding to the two first display regions 10 respectively, and the two substrate portions 142 are separated by the avoidance region 141.

[0044] The first lower substrate 14 can be a large substrate, which is then cut into two pieces by laser etching or other cutting methods to form the two substrate parts 142, thereby finally forming the first lower substrate 14; or, the first lower substrate 14 directly uses two separate small substrates as the two substrate parts 142.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the embodiments of the utility model rather than to limit them.
