Description

Flat screen touch input mobile terminal

technical field

The utility model relates to a flat touch input mobile terminal.

Background technique

As shown in FIG. 1 , the touch input mobile terminal has a structure that a touch screen 2 is pasted on a display screen 1 , and the touch screen 2 includes a base material layer and a circuit layer. The surface of the Touch Lens touch screen is flat, and the substrate layer is made of thicker glass material. In order to realize the flat structure on the upper surface of the mobile terminal, the flat touch input mobile terminal in the prior art uses Touch Lens as its touch screen. However, such a touch screen not only has a high cost, but also has a large thickness, which leads to a thick and heavy appearance of the mobile terminal, which takes up a large space and is not conducive to carrying.

Since when using the touch screen 2 to input information into the mobile terminal, it is necessary to use a stylus or a finger to repeatedly swipe across the surface of the touch screen 2, which may easily cause wear on the surface of the touch screen 2. Consumers often stick a protective film on the surface of the touch screen 2 after purchasing the mobile terminal with flat touch input in the prior art. This not only increases the user's cost, but also forms a raised edge on the outer surface of the mobile terminal, which not only affects the surface smoothness of the mobile terminal, but also easily causes the edge of the protective film to warp or roll up, which affects the appearance and use. In addition, the process of attaching this protective film requires certain skills. If air bubbles are formed between the protective film and the touch screen 2 or the protective film is not smooth, it will not only be unsightly, but also affect the accuracy of input. speed and efficiency.

Utility model content

The purpose of the utility model is to provide a thinner and thinner mobile terminal with flat touch input, which does not require the user to attach a protective film by himself, which will cause the surface of the mobile terminal to be uneven and inconvenient to use.

A mobile terminal with a flat touch input includes a display screen, a touch screen and a casing. The casing includes an upper case located at the top end of the display screen, a lower case located at the bottom end of the display screen, and a protective layer attached to the touch screen.

The flat touch input mobile terminal provided by the utility model has a high surface smoothness and does not require a user to attach a protective film to prevent the inconvenience of use caused by the edge of the protective film being lifted or rolled up. In addition, the utility model has a thinner touch screen, which not only makes the appearance of the mobile terminal thinner, but also effectively reduces the manufacturing cost.

Description of drawings

Fig. 1 is a structural schematic diagram of affixing a protective film on a flat touch input mobile terminal in the prior art;

2 to 5 are structural schematic diagrams of the flat touch input mobile terminal provided by the present invention.

Detailed ways

As shown in Figure 2, a flat touch input mobile terminal includes a display screen 4, a touch screen 5 and a casing, the casing includes an upper casing 71 positioned at the top end of the display screen 4 and a lower casing 72 positioned at the bottom end of the display screen 4 And the protective layer 6 attached on the touch screen 5 . The touch screen 5 includes a substrate layer and a circuit layer. Since the flat touch input mobile terminal is a three-layer structure of display screen 4, touch screen 5 and protective layer 6 superimposed in sequence, it can The touch screen 5 is manufactured into a thinner structure than the touch screen in the prior art, thereby reducing the manufacturing cost of the substrate layer. The protective layer 6 can be made of PET material with a thickness of 0.2 to 0.4 cm. Various surface treatment processes can be performed on the protective layer 6 to increase the aesthetic effect of the surface of the mobile terminal.

Further, the touch screen is a Touch Panel touch screen. The thickness of the Touch Lens touch screen is 1.7cm, while the thickness of the TouchPanel touch screen is only 1.0cm. In this way, the appearance of the mobile terminal can be made thinner and lighter, and the cost is lower.

Further, the display screen is provided with a first flexible circuit board (Flexible Printed Circuit, FPC); the touch screen is provided with a second flexible circuit board. The first flexible circuit board is connected to the second flexible circuit board. In this way, not only is the assembly more convenient during the manufacturing process of the mobile terminal, but also there is no need to provide pads for welding the second flexible circuit board on the main board, which can reduce the manufacturing cost of the main board of the mobile terminal.

As shown in FIG. 2 and FIG. 3 , the height of the upper shell 71 is equal to that of the lower shell 72 , and the upper surface of the touch screen 5 is lower than the upper surface of the outer shell.

Each part of the protective layer 6 has the same thickness and a cross-section of "one", and the protective layer 6 is arranged between the upper shell 71 and the lower shell 72 . In this way, the area of the protective layer 6 is small, which can further reduce the manufacturing cost of the mobile terminal.

The protective layer 6 includes a thick part 61 and a thin part 62 with a "T" shape in cross section, the thick part 61 is attached to the touch screen 5, and the thin part 62 is attached to the upper case 71 and the upper shell 71 respectively. On the lower shell 72. In this way, the upper surface of the mobile terminal can be made to have a seamless structure, increasing the flatness of the surface of the mobile terminal.

As shown in FIG. 4 , the height of the upper case 71 is greater than that of the lower case 72 , and the upper surface of the touch screen 5 is lower than the upper surface of the lower case 72 .

Further, the protective layer 6 includes a thick portion 61 and a thin portion 62 with an “L” shape in section, the thick portion 61 is attached to the touch screen 5 , and the thin portion 62 is attached to the lower case 72 superior. In this way, by adjusting the thickness of the protective layer 6, the outer surface of the housing can be more precisely on the same plane.

As shown in FIG. 5 , a concave edge 74 matching the thickness of the protective layer 6 and used for attaching the protective layer 6 is provided on the outer shell.

A flange 73 for clamping the display screen 4 is provided on the housing. In this way, the flange 73 presses on the display screen 4, so that the display screen 4 is fixed more stably, even if the mobile terminal is accidentally dropped, the display screen 4 will not fall off.

A protruding portion 41 is disposed on a side of the display screen 4 , and the flange 73 presses on the protruding portion 41 . In this way, the utilization area of the display screen can be increased. A plurality of the raised portions 41 may be dispersedly arranged on the side of the display screen 4 , or one ring-shaped raised portion 41 may be arranged along the side.
