[0024] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings.

[0025] This application proposes a high contrast display component, see Figure 1 , including: two completely identical LCD panels 10, a driver chip and a circuit board. The two LCD panels 10 are bonded and connected on both sides of the display field by an adhesive 40, and a filter component 20 is arranged in the display direction of the two LCD panels 10. The filter component 20 can filter the light that interferes with the display field to achieve the effect of eye protection. The two LCD panels 10 are respectively conductively connected to the circuit board to provide current for the display of the two LCD panels 10. The driver chip is arranged on the circuit board to drive the two LCD panels 10 to display synchronously, wherein the model of the driver chip is UCi8533c, UC2621c, UC2628c or UC2631c.

[0026] It should be noted that the two LCD panels 10 are aligned through CCD so that the display segments of the two LCD panels 10 overlap, avoiding blurring of the display fields and improving the contrast of the display segments, so that the driver can observe the fields of the display components brighter and clearer, which is beneficial to the driver's driving experience.

[0027] Furthermore, the LCD panel 10 is in a rectangular parallelepiped shape, which has an excellent visual effect and avoids blocking the fields at the edges of the LCD panel 10, thereby displaying the complete fields.

[0028] In one embodiment, the filter assembly 20 includes three polarizers, one polarizer is arranged between two LCD panels 10, and the other two polarizers are arranged on both sides of the two connected LCD panels 10. The three polarizers decompose the incident natural light, only transmit the light with the corresponding polarization direction, and filter out the light in other directions, thereby achieving the functions of eye protection, eliminating reflections, etc., thereby reducing the driver's driving fatigue.

[0029] See also Figure 1 The embodiment of the present application also includes a connector 30, and the two LCD panels 10 are conductively connected to the circuit board through the connector 30. No welding process is required, and the LCD panel 10 and the circuit board are directly connected by plugging and unplugging, which is convenient for the maintenance and replacement of internal components.

[0030] For further information, see Figure 1 and Figure 2 , the circuit board connection positions of the two LCD panels 10 are on the same side to avoid the connector 30 being too long, so as to arrange the circuits simply. In one embodiment, the circuit board connection positions of the LCD panels 10 are all below the display direction and are staggered. Specifically, one LCD panel 10 is arranged on the left side and the other LCD panel 10 is arranged on the right side, so as to facilitate the connection of the circuit board with the external main board.

[0031] In addition, the adhesive 40 is an optical adhesive, which is colorless and transparent. While fully ensuring the bonding effect, it effectively improves the light transmittance. Furthermore, the optical adhesive is an OCA adhesive.

[0032] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
