Abstract
A chip on glass (COG) liquid crystal display module with press keys comprises a liquid crystal display (LCD) screen and a light emitting diode (LED) backlight. The COG liquid crystal display module with the press keys is characterized in that a COG bonding technique is adopted in the LCD screen. A dot matrix graph driven COG integrated circuit (IC) chip is arranged on the step on one side of the LCD screen in a bonding mode. Indium tin oxide (ITO) press keys are carved on the step on the other side of the LCD screen. Each of two sides of the LCD screen is respectively connected with an external control chip micro-programmed control unit (MCU) through each of flexible printed circuit (FPC) connectors. A semi-reflective semi-permeable display mode is adopted in the LCD screen. Five subminia-ture tube (SMT) lampwicks giving out light from one side are adopted in the LED backlight, so that light intensity is guaranteed to be 400 cd/m<2>. According to the COG liquid crystal display module with the press keys, the COG bonding technique is adopted and the ITO press keys are carved on the step on one side of the LCD screen. The COG liquid crystal display module with the press keys is compact in structure, small in size, ultra-low in power consumption and capable of working at night by using the LED backlight. Not only is a graphic display function achieved, but also a press key function is achieved.
Description
Technical field
The utility model relates to a kind of LCD LCD MODULE, is specifically related to a kind of COG LCD MODULE with button.
Background technology
The LCD screen is as main display device, be widely used in the numerous areas such as national defence, industry, family expenses, communal facility, industrial control instrument display requires higher: must be little, the wider operating temperature range of volume, low-power consumption, the various numerals of demonstration and character.Size liquid crystal display in traditional instrument can only realize simple demonstration on the LCD screen; If need button, just need to be on circuit board protracting circuit, needing increases a PCB circuit board, this has just caused the instrument volume large, processing technology is complicated, especially static current of lcd is high, can not satisfy the low-power consumption requirement.
Summary of the invention
For overcoming the deficiencies in the prior art, the utility model aims to provide a kind ofly can be realized showing on same LCD screen, integrated keypress function again, and volume is urinated in installation, the COG LCD MODULE with button of super low-power consumption.
For realizing above-mentioned technical purpose, the utility model is achieved through the following technical solutions:
A kind of COG LCD MODULE with button, comprise LCD display, LED-backlit source, it is characterized in that: described LCD display adopts COG nation to decide technology, nation decides dot pattern driving COG IC chip on side stage rank, be carved with the ITO button at opposite side LCD step, described LCD display both sides are connected with external control chip MCU by FPC connector respectively.
Described COG IC chip internal integrated LCD displaying screen controller, LCD display driver.
Described FPC connector adopts polyimide to do base material.
Described LCD display adopts the half-reflection and half-transmission display mode.
One-sided luminous five SMT(Surface Mounted Technology, surface installation technique are adopted in described LED-backlit source) wick, brightness guarantees at 400cd/m

Compared with prior art, the utlity model has following beneficial effect:
The utility model adopts the nation of COG to decide technology, and is carved with the ITO button at a side LCD step, and the compact conformation volume is little, super low-power consumption; Use the LED-backlit source working at night; Namely can the real time graphic display function, can realize keypress function again.
Description of drawings
Fig. 1 shows explosive view of the present utility model.
Among the figure: 1, LCD display, 2, dot pattern drives COG IC, 3, the ITO button, 4, FPC connector (IC side), 5, FPC connector (key-side), 6, backlight
Embodiment
Below with reference to accompanying drawing also in conjunction with the embodiments, describe particular content of the present utility model in detail.
Referring to shown in Figure 1, a kind of COG LCD MODULE with button, comprise LCD display (1), LED-backlit source (6), described LCD display adopts COG nation to decide technology, nation decides dot pattern driving COG IC chip (2) on side stage rank, be carved with ITO button (3) at opposite side LCD step, described LCD display both sides are connected with external control chip MCU by FPC connector respectively.Described COG IC chip internal integrated LCD displaying screen controller, LCD display driver.Described FPC connector adopts polyimide to do base material.Described LCD display adopts the half-reflection and half-transmission display mode.One-sided luminous five SMT(Surface Mounted Technology, surface installation technique are adopted in described LED-backlit source) wick, brightness guarantees at 400cd/m
2
External control chip MCU drives COG IC input data by parallel interface to dot pattern, is then written to the corresponding position of LCD display through calculating by programmed control, so understands in the required content of LCD screen display.Button is connected to touch-control IC, and by external signal MCU is sent instruction.
The above is preferred embodiment of the present utility model only, is not limited to the utility model, and for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
