Abstract
The invention discloses a superposition-combined COG (Chip On Glass) LCD (Liquid Crystal Display) module which comprises a first LCD screen which can display segment codes and icons, wherein the first LCD screen is bound by a first single COGIC chip to drive 160 segment code pixels; the first single COGIC chip is connected with a master FPC (flexible printed circuit) connector by a slave FPC connector; a second LCD screen which can display a 240*160 dot matrix pixel is also arranged below the first display screen; the second LCD screen is bound by a second single COGIC chip to drive a 240*160 dot matrix pixel; the second single COGIC chip is connected with an external controller by the master FPC connector; and the lower part of the second LCD screen is provided with an LED back light source. By adopting the LCD module provided by the invention, positive display or negative display or the combination of positive display and negative display can be realized, and stoke segment type display or raster graphics display can also be realized.
Description
Technical field
The present invention relates to a kind of LCD LCD MODULE, the concrete COG liquid crystal display module that relates to stack combinations.
Background technology
The LCD screen is as main display device; Be widely used in numerous areas such as national defence, industry, family expenses, communal facility; Traditional LCD MODULE can only be confirmed a kind of display mode: just showing or negative showing; Can not arbitrarily switch, the display pattern type also can only be segment code type or dot matrix graphic, and two kinds of display modes respectively have relative merits.Bright dark variation also can only be carried out in the traditional backlight source, and backlight luminescence area, shape are in case confirm and can not change.
Summary of the invention
For overcoming the deficiency of prior art, the present invention aims to provide a kind of demonstration that can realize just showing or bearing, and also can both combine; Can realize that a segmentation shows or the COG LCD MODULE of the stack combinations that dot pattern shows.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the present invention realizes through following technical scheme:
A kind of COG liquid crystal display module of stack combinations; But it comprises first LCD display of a display segment code and icon; Said first LCD display adopts first single COG IC chip nation fixed; Drive 160 segment encode pixels, said first single COG IC chip is connected with a main FPC connector from FPC connector through one, also be provided with below said first LCD display one can show 240 * 160 lattice pixels second LCD display; Said second LCD display adopts second single COG IC chip nation fixed; Drive 240 * 160 lattice pixels, said second single COG IC chip is connected with peripheral control unit through said main FPC connector, and said second LCD display below is provided with a LED-backlit source.
Further, said first LCD display adopts and just shows total transmissivity formula TN display mode.
Further, said second LCD display adopts the negative ASTN display mode that shows, and can realize that 32 grades of gray scales show.
Further, one-sided luminous five SMT (Surface Mounted Technology, surface installation technique) wick is adopted in said LED-backlit source, and brightness guarantees at 500cd/m
2
Further, said lead-out terminal from the FPC connector is welded on the said main FPC connector, is connected with peripheral control unit through said main FPC connector.
Compared with prior art, the present invention has following beneficial effect:
The present invention adopts the fixed technology of COG nation, and the compact conformation volume is little, super low-power consumption; Use segment encode+icon just showing the LCD display and negative bonding the combining of LCD display that shows the ASTN pattern of dot pattern of TN pattern, the cooperated with LED backlight is except that the demonstration advantage that has separately; Both combinations can realize forming three-dimensional dynamic effect; Various combinations are cooperated with backlight by the dot pattern LCD display fully by software control simultaneously, can realize intelligent backlight; Just in the viewing area; The shape of luminous zone, area, brightness can be controlled arbitrarily by program, combine with a section-type LCD display screen to form special-effect, can realize that counterweight is put digital special brightness indication or explanatory note shows.
Above-mentioned explanation only is the general introduction of technical scheme of the present invention, understands technological means of the present invention in order can more to know, and can implement according to the content of instructions, below with preferred embodiment of the present invention and conjunction with figs. specify as after.Embodiment of the present invention is provided by following examples and accompanying drawing thereof in detail.
Description of drawings
Accompanying drawing described herein is used to provide further understanding of the present invention, constitutes the application's a part, and illustrative examples of the present invention and explanation thereof are used to explain the present invention, do not constitute improper qualification of the present invention.In the accompanying drawings:
Fig. 1 shows explosive view of the present invention.
Fig. 2 shows the present invention and realizes various demonstration synoptic diagram.
Label declaration among the figure: 1, first LCD display, 2, first single COG IC chip, 3,, 4, second LCD display, 5, second single COG IC chip, 6, main FPC connector, 7, the LED-backlit source from FPC connector.
Embodiment
Below with reference to accompanying drawing and combine embodiment, specify the present invention.
Referring to shown in Figure 1; A kind of COG liquid crystal display module of stack combinations; But it comprises first LCD display 1 of a display segment code and icon, and said first LCD display 1 adopts first single COG IC chip 2 nation fixed, drives 160 segment encode pixels; Said first single COG IC chip 2 is connected with a main FPC connector 6 from FPC connector 3 through one; Said first LCD display 1 below also be provided with one can show 240 * 160 lattice pixels second LCD display 4, said second LCD display 4 adopts second single COG IC chip 5 nation fixed, drives 240 * 160 lattice pixels; Said second single COG IC chip 5 is connected with peripheral control unit through said main FPC connector 6, and said second LCD display 4 belows are provided with a LED-backlit source 7.
Further, said first LCD display 1 adopts and just shows total transmissivity formula TN display mode.
Further, said second LCD display 4 adopts the negative ASTN display mode that shows, and can realize that 32 grades of gray scales show.
Further, one-sided luminous five SMT (Surface Mounted Technology, surface installation technique) wick is adopted in said LED-backlit source 7, and brightness guarantees at 500cd/m
