Abstract
The utility model relates to a controller with a back light liquid crystal display for an air conditioner. The utility model is suitable for an occasion of operating the controller at night or in dark. The utility model comprises a panel press key, a sampling system, a driving system, a liquid crystal display screen, a control chip, and power supply. The utility model is characterized in that the control chip is a TMP87C846N single-chip computer produced by TOSHIBA, and the utility model is also comprises a driving chip which outputs a driving command after multiple filtrations when receiving an output signal of the control chip; a back light source which can receive the output signal of the driving chip and facilitate the liquid crystal display screen to emit light is arranged behind the liquid crystal display screen. The utility model has the characteristics that the display screen can be seen clearly, the operation is convenient, etc.
Description
The utility model relates to a kind of air-conditioner controller, particularly a kind of air-conditioner controller with liquid crystal display backlight, the occasion that the operating air conditioner controller used when it was applicable to night or light dark.
In background technology, the operating air conditioner controller has to open illuminating lamp when night or light dark, and this has brought great inconvenience to the user, for overcoming these defectives, it is improved.
The purpose of this utility model provides a kind of air-conditioner controller with liquid crystal display backlight, and it can clearly see the show state of display screen, user friendly operation clearly when night or light dark.
The purpose of this utility model is achieved in that
It has panel button, sampling system, drive system, LCDs, control chip, power supply,
Described control chip is the TMP87C846N single-chip microcomputer that Toshiba produces,
Carry out after the repeatedly filtering when receiving above-mentioned control chip output signal in addition and export a driving chip that drives instruction,
Be provided with behind at described LCDs and can receive drive chip signal output, and make its luminous backlight.
Described driving chip is the TMP47C422N chip that Toshiba produces.
Described backlight is that one group of light emitting diode constitutes.
The utility model is compared the good effect that is produced with background technology:
1, because the utility model adopts TMP87C846N control chip, driving chip to make backlight luminous, so can when night or light dark, clearly see the show state of display screen, user friendly operation clearly.
Fig. 1 is circuit theory diagrams of the present utility model.
Fig. 2 is the enforcement circuit diagram of Fig. 1.
Below in conjunction with accompanying drawing, the utility model is done to describe further:
Referring to accompanying drawing, when in night or dark, needing the operating air conditioner controller, press the button of sleeping in the remote controller 9, make it be in non-sleep pattern, give sampling system 2 one non-sleep signals, sampling system 2 is handled back output one signal and is given TMP87846N control chip 5, output one signal drives chip 7 to TMP47C422N after TMP87C846N control chip 5 is handled, TMP47C422N drives chip 7 after filtering repeatedly, and export a drive LCDs 4 backlight 8 behind, make it luminous.When it is not luminous, press the button of sleeping in the remote controller 9, make it be in sleep pattern, give sampling system 2 one sleep signals, sampling system 2 is handled back output one signal and is given TMP87C846N control chip 5, handles back output one signal through TMP87C846N control chip 5 and drives chip 7 to TMP47C422N, and TMP47C422N driving chip 7 is after filtering repeatedly, and export a drive LCDs 4 backlight 8 behind, make it not luminous.
Claims (3)
