The invention discloses a liquid crystal instrument with a 12.3-inch all-plastic shell. The liquid crystal display module comprises a front frame, foam, a light-transmitting surface, back glue, a TFTliquid crystal screen, a TFT support, a PCB and a rear cover. The PCB is connected with the rear cover through bolts. The TFT liquid crystal screen and the TFT support are connected through bolts. TheTFT liquid crystal screen and the TFT support which are assembled and connected are connected to the rear cover through bolts, the back glue is adhered to one side face, opposite to the TFT support,of the TFT liquid crystal screen, the light-transmitting face is adhered to the TFT liquid crystal screen through the back glue, a layer of foam is adhered to the surface of the light-transmitting face, and the front frame and the rear cover are connected together through buckles and bolts. The weight of the instrument can be reduced, the LENS surface adopts a plane design, the material consumption is reduced, the rear cover adopts a plastic material, the weight is reduced, and the instrument production process is simplified; and after the rear cover is changed into the plastic shell from an aluminum plate, the original stamping, cutting and polishing processes are simplified into a plastic injection molding process.

    本发明公开了一种12.3寸全塑胶外壳的液晶仪表,包括前框架、泡棉、透光面、背胶、TFT液晶屏、TFT支架、PCB板以及后盖,PCB板与后盖采用螺栓连接,TFT液晶屏和TFT支架采用螺栓连接,组装连接好的TFT液晶屏和TFT支架采用螺栓连接到后盖上,背胶粘在TFT液晶屏上与TFT支架相对的一侧面上,透光面通过背胶粘到TFT液晶屏上,透光面的表面粘有一层泡棉,前框架和后盖通过卡扣+螺栓连接于一起。本发明能够降低仪表重量:LENS面采用平面设计,减少材料用量,后盖采用塑胶材质,降低重量,简化仪表生产工艺:后盖由铝板改为塑料壳后,由原冲压、切割、打磨工艺简化为塑胶注塑工艺。
