The LCD hybrid display module 3 includes a TFT display screen 31, and segment code screens 32 are respectively disposed on two opposite sides of the TFT display screen 31. The TFT display panel 31 has a rectangular structure, and segment code panels 32 are respectively disposed at corresponding positions of two short sides of the rectangular structure, that is, the segment code panels 32 are disposed at corresponding positions of two short sides of the rectangular structure. That is, the TFT display panel 31 is located between two segment code panels 32, and the three are linearly distributed. The TFT display panel 31 located at the center serves as a main display area, and the segment display panels 32 located at both sides of the TFT display panel 31 serve as side display areas. Meanwhile, a plurality of backlight sources corresponding to each display area are arranged on the PCBA 5, so that the display areas are not interfered with each other. As for the circuit design on the PCBA board 5, the circuit principle of the existing PCBA board can be referred to, and the related technology is mature and will not be described in detail. The segment screen 32 includes a liquid crystal layer 321, a lower glass 322, a lower polarizer 323, and a color film 324, which are sequentially disposed from top to bottom, and the shapes of the liquid crystal layer 321, the lower glass 322, and the lower polarizer 323 are all matched with the color film 324, and the color film is used to achieve a color display effect of the segment screen 32. An upper glass 33 is arranged above the TFT display 31, and the upper glass 33 covers the TFT display 31 and the segment screen 32, namely the area of the upper glass 33 is at least equal to the sum of the area of the TFT display 31 and the area of the segment screen 32. In addition, the upper glass 33 is provided with an upper polarizer 34 on the side opposite to the TFT display screen 31, and the size and shape of the upper polarizer 34 and the upper glass 33 are matched.
