The light-emitting unit is exposed outside of a rear casing part of the casing. The power supply unit can generate a first power signal. The voltage conversion unit is controlled by a power supply control signal to convert the first power signal into a second power signal, and provide it to the light-emitting unit. The control unit is electrically connected with the light-emitting unit and the voltage conversion unit, and can generate a light-emitting control signal for controlling the light-emitting unit to emit light, and a power supply control signal. The switch is exposed on the rear casing and can be operated by a user, and is electrically connected between the voltage conversion unit and the control unit. When it is in a short-circuit state, the power supply control signal is allowed to pass through. When it is in an open circuit state, the power supply control signal is not allowed to pass through.

In some embodiments, the display also includes a base connected to the housing, the base includes a base located below the housing, and an extension arm connected to the base and the housing, The shell can pivot to the base so that the rear shell part can face downward or rearward.

In some embodiments, the light-emitting unit has a strip shape and is adjacent to and extends along the periphery of the rear shell.

The effect of the present invention is that the voltage conversion unit is controlled by the power supply control signal to convert the first power signal into the second power signal and provide the second power signal to the light-emitting unit, and the control unit The light-emitting control signal and the power supply control signal are generated, and the switch can be operated by the user to allow or disallow the power supply control signal to pass, so that the display also has the function of a desk lamp and expands the use range of the display .

Before the present invention is described in detail, it should be noted that in the following description, similar elements are denoted by the same numbers.

1, 2 and 3, an embodiment of the display 100 of the present invention includes a housing 1, a light-emitting unit 2, a power supply unit 4, a voltage conversion unit 5, a control unit 3, and a switch 6. A storage unit 7 and a base 8.

The casing 1 includes a rear shell portion 11 and a front frame body 12, and is used for accommodating the light-emitting unit 2, the power supply unit 4, the voltage conversion unit 5, the control unit 3, the switch 6 and the storage Unit 7.

The light-emitting unit 2 is disposed on the casing 1 and exposed to the rear casing 11. The light-emitting unit 2 has a strip shape and is adjacent to and extends along the periphery of the rear shell portion 11. In this embodiment, the light-emitting unit 2 is an LED unit, but it is not limited to this.

The power supply unit 4 is disposed in the casing 1 and can generate a first power signal with a first voltage value (for example, 19V).

The voltage conversion unit 5 is disposed in the housing 1 and is electrically connected between the power supply unit 4 and the light-emitting unit 2, and is controlled by a power supply control signal to convert the first power signal into a signal with a phase difference The second power signal of the second voltage value (for example, 5V) of the first voltage value is provided, and the second power signal is provided to the light-emitting unit 2.

The storage unit 7 is disposed in the casing 1 and is electrically connected to the control unit 3. The storage unit 7 stores a setting value related to the light-emitting unit 2 and indicating enable or disable. In this embodiment, the user can set the content of the setting value through the OSD menu.

The control unit 3 is disposed in the casing 1 and is electrically connected to the light-emitting unit 2 and the voltage conversion unit 5, and can generate a light-emitting control signal for controlling the light-emitting unit 2 to emit light, and the power supply control signal. When the setting value indicates enabling, the control unit 3 generates the light-emitting control signal, and when the setting value indicates disabling, the control unit 3 does not generate the light-emitting control signal.

The switch 6 is disposed on the casing 1 and exposed to the rear casing 11 to be operated by a user in a short-circuit state or an open-circuit state, and is electrically connected between the voltage conversion unit 5 and the control unit 3. When in the short-circuit state, the switch 6 allows the power supply control signal to pass, and when in the open state, the switch 6 does not allow the power supply control signal to pass. Thereby, even if the panel unit of the display 100 is closed, the user can turn on the light-emitting unit 2 or turn off the light-emitting effect by operating the switch 6 so that the user can use the display 100 as a lamp.

Referring to FIGS. 1 and 4, the base 8 is connected to the casing 1 and includes a base 81 located below the casing 1 and an extension arm 82 connected to the base 81 and the casing 1. The shell 1 can pivot the base 8 so that the rear shell portion 11 can face downward (as shown in FIG. 4) or rearward (as shown in FIG. 1). Thereby, when the display 100 is used as a desk lamp, it is convenient for the user to adjust the illumination angle.

In summary, the display 100 of the present invention converts the first power signal into the second power signal by the voltage conversion unit 5 being controlled by the power supply control signal and provides the second power signal to the light emitting unit 2, and The control unit 3 generates the light-emitting control signal and the power supply control signal, and the switch 6 can be operated by the user to allow or prevent the power supply control signal from passing, so that the display 100 also has the function of a desk lamp Therefore, the scope of application of the display 100 is expanded, so it can indeed achieve the purpose of the invention.
