Embodiment Construction

[0025] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0026] In the embodiment of the present invention, all functions of traditional TV key control are realized by pressing the turntable, rotating the turntable, pressing the Standby key and combining corresponding on screen menu functions (On Screen Display, OSD).

[0027] The devices required by the embodiment of the present invention include a rotary encoder, a keyed PCB board, a turntable, a button, a single-key plastic button row and connecting lines (less than 6) from the keyed board to the main board.

Abstract

The invention provides a device for controlling a TV press key and a TV which is applicable to the TV field. The device for controlling the press key comprises a press key switch which is pressed or rotated to realize the keying operation; an encoder which is connected with the press key switch and outputs a first signal and a second signal according to rotation direction and rotation amplitude of the press key switch; a control switch which is connected with the press key switch and is communicated with a circuit between an external power and the press key switch to output a confirmed signal when the press key switch is pressed. In the embodiment of the invention, the adoption of the passive mechanical rotary encoder realizes the press key control of the TV and realizes all the functions of press key control of the traditional TV through pressing and rotating the press key switch, and combining corresponding design of a screen menu. The device provided by the embodiment of the invention requires less devices with a simple layout of circuit and press key, fewer openings on the panel shell the TV, and thus rendering a more attractive outlook.

Description

technical field [0001] The invention belongs to the field of televisions, and in particular relates to a button control device for a television and the television. Background technique [0002] At present, the devices that need to be used in the key control device of the TV include key control printed circuit board (Printed Circuit Board, PCB), channel +, channel -, volume +, volume -, menu, standby (Standby), signal source, etc. 6 - 8 buttons, plastic buttons and the connection line from the keying PCB board to the TV main board. There are generally two situations for connecting the keying PCB board to the main board of the TV: When the microcontroller (Micro Control Unit, MCU) of the system has an analog-to-digital converter (Analog-Digital Converter, ADC) interface, there are 4 bits in total. The connecting wires are ground wires GND, +5V, ADC1, and ADC2. At this time, the keying PCB board needs to have a voltage divider resistor, the circuit is more complicated, and the...
