When the user touches first function pattern district 11 or second function pattern district 12, first function pattern district 11 and second function pattern district 12 can be some function catalogue LOGO, and first FPC touch button 2 or second FPC touch button 3 can sense, thereby realize the click selection of function catalogue LOGO, can realize the direction selection function when first multi-functional rotating button of user control or the multi-functional rotating button of second, for full-screen touch low-cost on-vehicle touch-sensitive screen, the utility model provides a low-cost on-vehicle touch-sensitive screen can reduce design and production manufacturing cost by a wide margin, satisfies the cost requirement of some low-end motorcycle types, improves product competitiveness.

Referring to fig. 1 to 3, further, the first FPC touch key 2 includes a main body 21, a connection portion 22 connected to the main body 21, and a gold finger 23 connected to the connection portion 22, and two reinforcing plates 24 are disposed on outer surfaces of two sides of the connection portion 22 and staggered with each other. In the conventional design of the first FPC touch key 2, the reinforcing plate 24 is usually not provided or the reinforcing plate 24 is provided at the same position and the width of the reinforcing plate 24 is the same, so that when the first FPC touch key 2 is pulled out, the applied pressure is concentrated on the same straight line, which causes the circuit of the first FPC touch key 2 to be slightly broken. The utility model provides a first FPC touch button 2 is because two stiffening plates 24 are located connecting portion 22's both sides respectively and stagger the setting each other, when extracting first FPC touch button 2, the pressure that first FPC touch button 2 was given to both sides stiffening plate 24 is not on same line segment, and stress can not concentrate on same straight line when buckling yet, avoids stress concentration from this, and the problem of the easy slight outage of the circuit of golden finger 23 department improves the product yield.

Furthermore, the two reinforcing plates 24 staggered with each other in the present invention may be respectively disposed at two different positions; the positions of the central points can be the same, but the widths of the two reinforcing plates 24 are different, and the stress generated when the two reinforcing plates 24 are bent is not concentrated on the same straight line, so that the problems that the stress is concentrated and the circuit at the golden finger 23 is easily broken slightly can be solved, and the product yield is improved. In this embodiment, the reinforcing plates 24 include a first reinforcing plate and a second reinforcing plate, the width of each reinforcing plate 24 is different, and the center points of the reinforcing plates 24 are located on the same horizontal line, so that the edges of the reinforcing plates 24 are staggered from each other, and are not concentrated on the same straight line.

Further, the material of the reinforcing plate 24 is FR4, PI or stainless steel, and in other embodiments, if the heat generation amount of the first FPC touch key 2 is large, a heat dissipation material with better heat dissipation effect, such as an aluminum foil reinforcing plate 24, may also be used.

Furthermore, the outer surface of the reinforcing plate 24 is provided with a diamond knurl, so that the first FPC touch key 2 can be pulled out more easily when pulled out, and the risk of circuit fracture of the first FPC touch key 2 is reduced.

Referring to fig. 1 to 4, further, a TFT module and an iron frame 4 for supporting the TFT module are disposed below the cover plate 1, the TFT module includes a lower polarizer 5, an array substrate 6, a color filter substrate 7 and an upper polarizer 8, which are sequentially stacked, and the color filter substrate 7 and the array substrate 6 are staggered to form a step. At least two buckles 41 are arranged on the iron frame 4, and the buckles 41 buckle the steps to prevent the backlight module from separating from the TFT module. The embodiment adopts four buckles 41 which are symmetrical with each other in pairs at the left and the right, but the invention is not limited thereto, and in other embodiments, only two buckles 41 can be adopted, but the stability is not as good as that of the four buckles 41 of the embodiment. The color filter substrate 7 is arranged above the array substrate 6, and the step buckled by the buckle 41 is a position where the upper surface of the array substrate 6 is staggered from the color filter substrate 7. The array substrate 6 includes a circuit area and a non-circuit area, and the position where the latch 41 is fastened in the embodiment is preferably the non-circuit area to prevent the circuit of the array substrate 6 from being affected. The utility model provides a liquid crystal display module, its simple structure, the technology is ripe, and low cost can make the TFT module firmly fix on iron stand 4, only need during the assembly with the TFT module press can, not waste time and energy, assembly efficiency is high, can effectively improve production efficiency.

Further, still be equipped with gasket 9 under the TFT module, gasket 9 can be selected to use bubble cotton or sponge rubber, and the preferred bubble of this embodiment is cotton, and the bubble is cotton not only can play the dustproof effect between TFT module and the backlight unit, can also guarantee to play the cushioning effect in TFT module assembling process. In other embodiments, sponge rubber can be used, which not only can play the above role, but also can firmly adhere the backlight module and the TFT module, and further prevent the backlight module from separating from the TFT module. More preferably, the thickness delta of the gasket 9 is larger than or equal to 0.3mm, so as to ensure that the TFT module plays a buffering role, the gasket 9 has enough thickness to elastically deform, the elastic force generated by the elastic deformation can exert certain pressure on the TFT module, so as to ensure that the TFT module can be more firmly clamped by the clamping buckle 41, and when the thickness delta of the gasket 9 is too small, the elastic force is small, so that the sufficient pressure cannot be generated on the TFT module, and the TFT module is easy to fall off.

Referring to fig. 1 to 5, further, the upper surface of the spacer 9 is coated with a weak-viscosity glue 91, the lower surface of the spacer 9 is coated with a strong-viscosity glue 92, the TFT module is attached to the upper surface of the spacer 9, and the backlight module is attached to the lower surface of the spacer 9, so that the spacer 9 not only can play a role in buffering and dust prevention, but also can prevent the upper surface of the spacer 9 from pulling the lower polarizer 5 in the TFT module to avoid MURA due to the weak-viscosity glue 91 coated on the upper surface of the spacer 9, thereby preventing the lower polarizer 5 from deforming; meanwhile, the number of layers of the gasket 9 is small, so that the gasket 9 can be prevented from falling off, and the TFT module is further prevented from falling off.

Further, the lower surface of gasket 9 still is equipped with PET layer 93, strong viscidity glue 92 is located the lower surface of PET layer 93, the lower surface of gasket 9 still is equipped with PET layer 93, and the lower surface on PET layer 93 is located to strong viscidity glue 92, owing to be equipped with PET layer 93 as the discernment, can play the effect of preventing slow-witted.

Further, the initial adhesion ratio of the strong adhesive glue 92 to the weak adhesive glue 91 is 2:1 to 50:1, and the upper surface of the gasket 9 is prevented from pulling the lower polarizer 5 in the TFT module by controlling the glue adhesion to avoid MURA, so as to prevent the lower polarizer 5 from deforming.

The above embodiments only express the embodiments of the present invention, and the description thereof is specific and detailed, but the invention can not be understood as the limitation of the patent scope of the present invention, but all the technical solutions obtained by adopting the equivalent substitution or equivalent transformation should fall within the protection scope of the present invention.
