Abstract
The utility model relates to a television with a current state and time display device, which belongs to a television circuit. The utility model comprises a housing and an antenna and high-frequency tuner, an infrared remote control and accept device, a micro computer processor, a brightness signal processing and chrominance decoding device, a line-field output and a machine core electronic circuit which is composed of a display device, a system exchange device, an AV conversion device, an audio signal input exchange device, an audio power amplification device, a loudspeaker, a power supply and other circuits which are respectively and mutually connected, wherein the micro computer processor is also connected with an IIC bus and an operation and display driving chip. The operation and display driving chip is connected with a VFD displayer and is mu PD16311 type, and the VFD displayer is composed of a digital tube or an LCD. The utility model can apply the VFD which can display the current operating condition which is usually used on white household appliances on a television, so the television can display the current channel, sound volume, scanning mode, time and other information at any time, the utility model has more humanization and is suitable for being used in various televisions, and users can be provided with more convenience.
Description
Technical field
The utility model belongs to technical field of television sets, more particularly relates to the design of the television set that has current state and time display.
Background technology
Existing television set does not all have current state and time display (VFD).That is to say, all information such as the current state of television set and time can not be shown on the panel of television set.This just brings inconvenience to the user---can't when watching, understand the working conditions such as current channel, volume, scanning mode of television set at any time, so that in time regulate; Also can't see information such as time at any time, for the user provides more convenience.More and more trend towards in the trend of hommization at home appliance, this can't but be a kind of defective of television set.
Summary of the invention
The purpose of this utility model, just be to overcome above-mentioned shortcoming and defect, provide a kind of VFD of demonstration work at present state that white domestic appliances are commonly used to be applied on the television set, make television set can show information, hommizations more such as current channel, volume, scanning mode and time at any time, make the convenient television set that has current state and time display of user.
In order to achieve the above object, the utility model comprises casing and is installed in movement electronic circuit in the casing.The movement electronic circuit comprises successively that the antenna of interconnection and high-frequency tuner, infrared remote control and reception, micro processor, luminance signal processing and chroma decoding, a row output and display, standard are switched, AV conversion, audio signal input are switched, audio power amplification and circuit such as loud speaker and power supply.Micro processor also is connected with operation and display driver chip through iic bus, and operation and display driver chip are connected with the VFD display again.Operation and display driver chip are μ PD16311 type.
The utility model is by the operating state of remote controller control television set, become displaying contents by micro processor editor work at present state simultaneously, by iic bus information such as above-mentioned channel, volume, scanning mode are delivered in the VFD display and show through operation and display driver chip again.Each road power supply of operation and display driver chip and VFD display is then provided by power circuit.
Temporal information of the present utility model is set up on their own by the user when first start, and is stored in the remote controller.Because television set often is in off-position, so the accuracy of clock is relatively poor.Clock information is stored in the remote controller, accuracy is improved greatly.All temporal information in the machine can be refreshed during each remote control, time accuracy then depends primarily on the clock frequency of remote controller.Thereby accuracy can be brought up to 1/10000, that is the error in a week is one minute.The out of Memory of television set, as current channel, volume, scanning mode etc., after all editing as mentioned above, output to 16311 chips by the control of time-sharing multiplex iic bus by CPU, carry out binary coding operation and display driver by 16311 chips, output to the VFD display at last and be shown to the user.
The VFD display is made up of charactron or LCD.Adopt the charactron cost lower, but the charactron of holding in shown limit.Adopt LCD display can show more contents, but cost is higher.Adopt which kind of display actually, should decide according to the kind of television set and possible price/cost ratio.
The utility model provides a kind of VFD of demonstration work at present state that white domestic appliances are commonly used to be applied on the television set, make television set can show information, hommizations more such as current channel, volume, scanning mode and time at any time, make the convenient television set that has current state and time display of user.It can be widely used in the various television sets.
