The utility model content
For overcoming the deficiency of prior art, the utility model aims to provide a kind of pen section that can on same LCD screen, realize and shows that simultaneously volume is urinated in installation, the COB LCD MODULE of the band Chinese character base of super low-power consumption with character.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the utility model is realized through following technical scheme:
A kind of COB LCD MODULE with Chinese character base; It comprises one 3.0 inches LCD display; Said LCD display drives COB (chip On board through pair of conductive adhesive tape and the pen section that is arranged on the pcb board; Chip on board) IC is connected with character driving COB IC; Also be provided with a FFC (Flexible Flat Cable, flexible flat cable) connector on the said pcb board, said pen section drives COB IC and is connected with external control chip MCU through said FFC connector with character driving COB IC.
Further, also be provided with a metal coating press box above the said LCD display.
Further, said metal coating press box adopts cold rolling carbon steel thin plate, and said cold rolling carbon steel thin sheet surface is sprayed with pitch-dark.
Further, also be provided with a LED-backlit source below the said LCD display.
Further, 16 SMT of bottom-emission (Surface Mounted Technology, surface installation technique) wick is adopted in said LED-backlit source, and brightness guarantees at 200cd/m

Label declaration among the figure: 1, metal coating press box, 2, LCD display, 3, conductive adhesive tape, 4, the LED-backlit source, 5, pcb board, 6, the pen section drives COB IC, 7, character drives COB IC, 8, the FFC connector.
Embodiment
Below with reference to accompanying drawing and combine embodiment, specify the utility model.
Referring to shown in Figure 1; A kind of COB LCD MODULE with Chinese character base; It comprises one 3.0 inches LCD display, and said LCD display drives a COB IC 6 through pair of conductive adhesive tape 3 and pen section on being arranged on a pcb board 5 and drives COB IC 7 with character and is connected, realizes driving section and a character; Also be provided with a FFC connector 8 on the said pcb board 5, said pen section drives COB IC 6 and is connected with external control chip MCU through said FFC connector 8 with character driving COB IC 7.
Further, also be provided with a metal coating press box 1 above the said LCD display.
Further, said metal coating press box 1 adopts cold rolling carbon steel thin plate, and said cold rolling carbon steel thin sheet surface is sprayed with pitch-dark.
Further, also be provided with a LED-backlit source 4 below the said LCD display.
Further, 16 SMT wicks of bottom-emission are adopted in said LED-backlit source 4, and brightness guarantees at 200cd/m
2
External control chip MCU through the I2C interface pen section is driven COB IC and character driving COB IC imports data respectively, is then written to the corresponding position of LCD display through calculating by programmed control, so understands show pen section, character content on the LCD screen.
The preferred embodiment that the above is merely the utility model is not limited to the utility model, and for a person skilled in the art, the utility model can have various changes and variation.All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
