Description

Luminescent display using EL sheet {A display unit using Electro Luminescence sheet}

The present invention relates to a light emitting display using EL (Electro Luminescence) sheet, and in particular, the company name, product name, etc. of various home appliances and information and communication devices to be displayed on the EL screen to advertise I would have to.

In general, home appliances such as televisions, TVs, washing machines, refrigerators, and telecommunication devices such as cellular phones and PCS display the manufacturer's symbol mark and product name at a predetermined position for advertisement and identification purposes when the product is released. Conventionally, it has been displayed using a mark or a character of a matte.

Therefore, when the surrounding area becomes dark, the company symbol mark and product name of the matte are not visible, and there is a problem in that the advertising effect is reduced.

In addition, a portable terminal such as a cellular phone or a PCS is equipped with a display liquid crystal lamp for displaying the current call state and various functions, etc., which is usually a matte, which makes it difficult to identify at night or in a dark place.

Conventionally, in order to solve this problem, a light emitting effect is provided by using an LED, but a separate driving circuit is required to drive the LED, and thus spatial considerations are required in design. In addition, the cost of the LED itself was not negligible, so there was an economic burden.

In order to solve the above problems, the present invention solves the limitations on the installation space of the light emitting display device, reduces the cost, and uses the EL sheet to produce a clear advertising effect at night. The purpose is to provide.

In the light emitting display for an electronic device as a technical idea for achieving the object of the present invention, the glass portion located on the front surface and only the various shaped portions are inscribed transparently, and is attached to the rear of the glass portion to emit light when a control and power signal are applied. Light emitting display means comprising: an EL sheet portion; and a protective panel portion positioned on a rear surface of the EL sheet portion to protect the EL sheet portion; The invention is proposed to include an inverter unit for supplying a predetermined control and power signal to the EL sheet to stabilize the divergent light emitted and to control the movement of color and the blinking speed of light.

Hereinafter, with reference to the accompanying drawings for the configuration and operation of the embodiment of the present invention will be described in detail.

As shown in Figure 2 and 3, the subject innovation in the light emitting display for electronic devices,

Glass part 5 which is positioned on the front surface and only variously shaped portions are engraved transparently, EL sheet part 10 which is attached to the rear of the glass part 5 and emits light when a control and power signal is applied, and the EL A light emitting display module 20 disposed on a rear surface of the sheet portion 10 and configured to include a protective panel portion 15 protecting the EL sheet portion 10;

The EL sheet unit 10 includes an inverter unit 25 for supplying a predetermined control and power signal to stabilize the divergent light emitted and to control the movement of color and the blinking speed of light.

In addition, the EL sheet part 10 may be used by selecting one of the inorganic or organic EL sheet according to the application.

The following describes the operation of the present invention from now on.

1 is a schematic perspective view showing a television set to which the present invention is applied.

2 is an exploded perspective view showing each configuration of the present invention.

Figure 3 is a front view showing a state in which a part of the cut in the state of the present invention combined.

EL (Electroluminescence) is a kind of electroluminescence and emits light when electric current flows through a substance such as phosphorus or gallium arsenide. In other words, materials such as phosphorous and gallium arsenide, which cause electroluminescence, are deposited on a glass substrate with a thickness of several microns, and vertical and horizontal transparent electrodes are disposed in a lattice shape.

The present invention uses the electroluminescence phenomenon of EL as described above. Here, EL is used as the EL emitter, and a paper EL or linear EL is used. Electro luminescence sheet is used.

The production process of the present invention is as follows.

First, a company symbol mark or a product name, etc. on the opaque glass portion 5 coming to the front is made of a transparent portion so that light is emitted to the portion when the EL sheet portion 10 is emitted.

When the fabrication of the glass part is completed, the original EL sheet is cut to fit the size of the glass part 5, and then the cut EL sheet part 10 is adhered to the rear surface of the glass part 5.

In this case, the EL sheet part 10 may be selectively employed to suit the purpose of the organic or inorganic EL sheet.

In addition, the color of the EL seat portion 5 can be easily identified visually, standard blue green, green, orange, high brightness blue green line, line green, red, white, yellow green, pink, Filters White, yellow, Peru pink, blue, orange yellow, lavender and more than 15 colors are available.

After the EL sheet portion 10 is attached to the glass portion 5 as described above, the EL sheet portion 10 may be moved so that the inverter portion 25 and the EL sheet portion 10 exchange electrical signals with each other. Wiring process.

That is, one side of the wire having a predetermined length may be soldered and fixed to the power supply terminal at one end of the EL seat portion 10, and the other side may be connected to the output end of the inverter portion 25.

At this time, the inverter unit 25 controls the color and rhythm of the light emitted, and optimizes the emission state of the EL sheet unit 10 to maintain a stable color.

In addition, the fixed light emitted from the EL sheet part 10 may be flickered. In this case, the flickering speed may vary according to a setting value input by the manufacturer into the program.

In order to achieve the above object, the inverter unit 20 mainly uses a programmable picture IC having a microcomputer function.

For reference, the picture IC includes various protection circuits and EMI filters capable of detecting an output short circuit, an overcurrent, an output value, and a temperature.

As described above, when the wiring operation is completed, the assembly of the light emitting display module 20 is completed by attaching the protective panel unit 15 to the rear side of the EL sheet unit 10.

When the assembly of the light emitting display module 20 is completed, the present invention including the inverter unit 25 may be mounted on a predetermined portion of a front panel such as a television, a BC deck, a refrigerator, or a light emitting screen portion of a portable terminal.

The present invention can be applied to various home appliances or information communication devices.

First, the ambient light is used together with an illuminance sensor (not shown) or the like, and when the ambient light becomes dark, the illuminance sensor detects this and sends a detection signal to the inverter unit 25. Accordingly, the inverter unit 25 transmits the EL seat unit 10. When the power signal is sent to the EL sheet 10 is an embodiment of the light emitting.

In another embodiment, the inverter may output the main power on signal of each electronic product so that the EL sheet unit 10 may emit light when a terminal such as a TV, a refrigerator, a VSI, or a terminal such as a cellular phone is powered on. The method is also applied to the part 25.

Accordingly, in the case of home appliances, a symbol mark or a product name of a corresponding manufacturer may be emitted to immediately enjoy an advertisement effect, and in the case of a portable terminal, it may be useful to check the current time and various messages in a dark place. do.

As can be seen from the above description, the present invention can reduce the volume and weight compared to the existing light emitting display device by configuring the light emitting display display using the EL sheet unit 10 can solve the problem of the installation space and thus The advantage is that the assembly can be made easier.

In addition, since the light emitter itself is made of a sheet, it is not influenced by external shocks and may have a relatively long life compared to a conventional light emitter.
