Description

[0001] The present invention relates to a smart phone having a display for magnifying a screen,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a wristwatch-type smartphone having a display screen enlarging display, and more particularly to a wristwatch- A flat OLED panel of a glass substrate mounted on a removable portion of a small display terminal or a wristwatch smart phone to solve the problem of screen size in execution and viewing, or a flexible plastic OLED panel of a flexible substrate To a wristwatch-type smartphone having a display for enlarging a screen, which enables the user to surf the Internet in one direction.

Recently, tablet PCs and smart phones having touch screen and LCD display functions are widely used, and wristwatch type smart phones and smart watches are being released.

Currently, touch screens, display panels and LCDs are used in smartphones, LCDs and OLED displays are used in flat panel displays, and Galaxy Note3 is equipped with flexible OLED panels.

BACKGROUND ART OLED (Organic Light-Emitting Diodes) is a light emitting element that replaces a conventional LCD (Liquid Crystal Display), and usually includes a substrate, an anode, a hole injection layer (HIL) , An electron transport layer (ETL), an electron injection layer (cathode), and a cathode.

Materials / processes / processes based on OLED displays are used in flexible displays and transparent displays, and active matrix organic light emitting diodes (AMOLEDs) are used in medium to large flexible displays.

Flexible OLEDs require flexibility and stretchability, durability, high electrical conductivity and light transmittance for substrates and devices against mechanical stresses such as flexure / bending / twisting by using a flexible substrate, Indium tin oxide (InSnO) is mainly used as a transparent electrode (ITO) in a display.

1 is a basic conceptual diagram of a basic OLED pixel circuit composed of a TFT of a plastic OLED panel.

Each pixel in an OLED display is supported by at least two TFT circuits (TFT1, TFT2) that control the flow of electricity and control writing signals.

Each pixel of the passive matrix OLED display (PMOLED) is fabricated by patterning the anode electrode vertically and the cathode electrode laterally.

The active matrix OLED display (AMOLED) has a structure in which two thin film transistor (TFT) circuits are provided in each pixel as shown in FIG.

Flexible OLED displays provide OLED picture quality among the R, G, and B pixels of a pixel, and use carbon fiber-reinforced plastic as a flexible substrate to maintain optimal curvature (display bending).

2A and 2B are block diagrams of a conventional flexible display device.

The flexible display device includes a flexible display body 10 using an electrophoresis method and a banding drive film 100 attached to one surface of the display body 10. [

The display main body 10 is formed of a structure in which a thin film transistor for realizing an image on a flexible flexible substrate, a light emitting element, and an encapsulating layer for covering and protecting them are stacked. The display main body 10 uses a flexible flexible substrate instead of a rigid glass substrate (glass substrate), and thus has the characteristic that the display main body 10 can flex freely within a permissible range of its flexibility.

The banding drive film 100 is attached to one surface of the display main body 10 using an adhesive 20 and is sandwiched between the first and second electrodes 210 and 220 facing each other as shown in FIG. And the electric response medium 230 is interposed therebetween. The banding drive film 100 is driven on the principle that the electric response medium 230 is driven to one side according to the direction of the current flowing through the first and second electrodes 210 and 220 and a bending force acts on the band.

The display main body 10 with the banding drive film 100 attached thereto is moved along with the banding drive film 100 as the current is supplied from the drive module 140 to the banding drive film 100, Lt; / RTI > That is, a drive module 140 electrically connected to the banding drive film 100 is installed on one side of the display main body 10, and when current is supplied to the banding drive film 100 from the drive module 140, One of the first and second electrodes 210 and 220 becomes a positive electrode while the other electrode becomes a negative electrode, causing banding. Therefore, during storage, the display main body 10 is supplied with current so as to be bent as shown in FIG. 2B. Then, the display body 10, which is bent and thus reduced in volume, is stored in an appropriate storage destination and used.

Recently, a wristwatch-type smartphone is on the market, and it is difficult to view the existing wristwatch-type smartphone by executing the Internet surfing or other application (application) because the screen is small. To improve this, a screen with a large screen size is required.

However, existing flexible displays can be applied in conjunction with wristwatch-type smartphones. In addition to existing LCD displays, mini-flexible displays need to be installed in wristwatch-type smart phones. However, The wristwatch type smartphone was not released.
