THE PREFERRED EMBODIMENT OF THE PRESENT INVENTION

[0039] The electric apparatus offered in the present invention will be described in further detail with reference to the accompanying figures and the embodiments.

[0040] The present invention can be applied to a variety of electric apparatus such as CRT TV, LCD TV, plasma TV, LCD computer, display, DVD, and so on. Its effect is especially evident for TV and computer displays which take a long time for the eyes to enjoy the content of the screen. For description, the LCD TV will be used in the preferred embodiment of the present invention to describe the design and the implementation of the present invention, yet the present invention will not be limited to the application of the preferred embodiment.

[0041] Refer to FIG. 1, 2, and FIG. 3, the electric apparatus in the figures is LCD TV, wherein, 1 is LCD TV, 2 is the translucent shell, 3 is the operation unit, 4 is the secondary indication unit, 5 is the power supply ON/OFF device, and 6 is the display unit.

[0042] In this preferred embodiment, the display unit 6 is equipped with the operation unit 3, the secondary indication unit 4 and the power supply ON/OFF device 5, while the display unit 6, the translucent shell 2 and other components (such as sound boxes not shown in the figures) constitute the LCD TV 1.

[0043] Of course, the equipped positions of the power supply ON/OFF device 5, the secondary indication unit 4 and the operation unit 3 and the display unit 6 can be changed, wherein the translucent shell 2 is square, but it is not limited to this, and the display unit here is the LCD screen and the related fittings.

[0044] When the LCD TV 1 is in working condition or non-working condition, as shown in FIG. 2, the position of the operation unit and whether it is located on the front of the TV can not be determined, only the power supply ON/OFF device 5 and the secondary indication unit 4 can be seen from the front of the TV, wherein the secondary indication unit 4 is an on-off indicator light and also the triggering unit used to trigger the primary indication unit. It is certain that the triggering unit can also be equipped with another triggering switch while not use the secondary indication unit 4. When the secondary indication unit 4 is electrically connected with the primary indication unit, as shown in FIG. 4, the primary indication unit is six LEDs which emit blue light. The mounting position of the primary indication unit corresponds with the operation unit 3, and the operation unit 3 is six touching-type key-presses which respectively correspond with the menu key, the signal source key, the volume + key, the volume key, channel + key and channel key. With the operation unit 3, the pattern, volume and the channel of the TV can be adjusted.

[0045] When the power supply ON/OFF device 5 is connected, the secondary indication unit is illumined and the LCD TV 1 starts to work. The remote controller (not shown in the Figure) or the operation unit 3 in the LCD TV 1 can be used to operate the LCD TV 1 when it is desired. Since in most cases, the operation of the LCD TV 1 is performed by the remote controller, the use frequency of the operation unit is relatively low, and the visible operation unit will cause relatively large influence in the consumers if they watch TV for a long time at the visible position in the front of the TV.

[0046] Referring to FIG. 1, when the LCD TV 1 needs to be operated via the operation unit 3, the primary indication unit (not shown in the Figure) electrically connected with the secondary indication unit 4 is lightened by switching on the secondary indication unit 4, the primary indication unit lightens its vicinity, therefore the key-press sign silk-screen printed on the translucent shell 2 is illumined, which makes the operator can determine the position of the key-presses and distinguish the function of each key-press and makes the operation of the LCD TV 1 conveniently. The LCD TV 1 shown in FIG. 1 omits the positions of the power supply ON/OFF device 5 and the secondary indication unit 4 to intuitively embody the effect of the primary indication unit illumining the operation unit 3. Of course that the primary indication unit can also apply only a diode or similar indication device, such as laser generator, and the light omitted from the diode is blue or other color which is largely different from those of the operation unit 3 and the translucent shell 2. The translucent shell 2 is made of ABS, PC and color master batch, and its color is black. The color of the 6 key-presses is black or some other color relatively close to that of the translucent shell 2, and the translucent shell 2 is transparent. Therefore, after the diodes are illumined, the sign silk-screen printed on the translucent shell 2 can be lightened. The key-presses are located after of the translucent shell 2.

[0047] Since when the consumers want to operate the operation unit 3, the triggering unit needs to be triggered to control the working condition of the primary indication unit to show the position of the operation unit 3 and the function of each key. After a certain time interval (such as 10 seconds), the primary indication unit is automatically extinguished and the keys are again in the invisible status, which increases the interactive performance between the LCD TV 1 and the consumers.

[0048] The time interval here that the primary indication unit is illumined is fixed, which can be set as 10 s, 20 s or some other more appropriate time, and the time interval can be set through the circuit so that it can be adjusted by operating the operation unit 3 when it is desired.

[0049] Referring to FIG. 4, wherein KEY 1 is the power supply ON/OFF device 5, KEY 2, KEY 3, KEY 4, KEY 5, KEY 6 and KEY 7 are respectively the menu key, the signal source key, the volume + key, the volume key, the channel + key and the channel key, and they constitute the operation unit 3.

[0050] Operational principle is as below: the 7th pin of the socket XP2 is KEY_STANDBY_POWER, which is the power supply +5 of the power supply ON/OFF device, and also the power supply of the chips U1, U2, U3, U4 and TS02. When the LCD TV 1 is in the normal working condition, the output from the 10.sup.th pin of U4 is high level and V4 is properly conducted, and D18, D19 and D20 properly lightening.

[0051] When the user touches the power supply ON/OFF device, the output from the 10.sup.th pin of U4 is instantaneously changed to low level and V4 is instantaneously non-conducted, D18, D19 and D20 are instantaneously extinguished. Meanwhile, the CPU of the LCD TV 1 set IO2 as high lever after it receives the low level signal of IO1, V8 is normally conducted, Vgs of Q1 is 5V, Q1 is conducted and D1-D17 LCDs are supplied with +5V, and the other six corresponding key-presses are illumined to irradiate. At the same time, after the CPU receives the low level signal of the IO1, it starts up the timer to time and the time is set by the user by the TV menu and generally is 10 s, 20 s, and so on. Here the user can see the silk-screen on the front of each key and all kinds of adjustments of the LCD TV 1 are performed according to the prompt of the silk-screen. When the timing reaches the predetermined time, the IO2 is set as low lever by the CPU, V8 is non-conducted, Vgs of the Q1 is 0V and Q1 is non-conducted. +5V is not supplied to the LCDs D1-D17, and correspondingly, the other six lights of the key-presses are extinguished.

[0052] The above description is the preferred embodiment of the present invention, yet the present invention is not limited to this. Any obviously change thought by those skilled in the art and some modifications and improvements without departure from the principle of the present invention should be fell in the scope of the present invention.
