Description

Liquid crystal display device with built-in wireless transmission module and mobile phone using the device

technical field

The utility model relates to a liquid crystal display device, in particular to a main control terminal and a liquid crystal display module connected by a built-in wireless transmission module, so that the liquid crystal display module device and the mobile phone using the device can be separated.

Background technique

Most of the current liquid crystal display modules (LCD Module, hereinafter referred to as LCM) use a flexible printed circuit board (Flexible Print Circuit, hereinafter referred to as FPC) or a connector (Connector) as an external transmission interface. However, the wired transmission interface generally has the following problems:

1. The freedom of product design is limited:

For LCM with wired connection, the configuration of the transmission line must be considered in the development and application of its products, which will limit the variability between the LCM and the main control terminal, and affect the design freedom of mobile phone products.

2. High cost

For example, in a monitoring system, when the distance between the LCM and the main control terminal is very long, the cost of the transmission line will be relatively increased, and there will be a problem of signal attenuation when the transmission distance is long, so it is necessary to relatively increase the power intensity of signal transmission. will lead to an increase in cost.

3. The transmission line is in danger of breaking

When the transmission line passes through a movable mechanism, such as the pivot joint of a clamshell mobile phone, the FPC still has the problem of breaking under repeated flexing after long-term use.

At present, the LCMs on the market also have the function of wireless transmission, but the existing wireless transmission functions are all in the form of an external wireless transmission module, or built into the base of a large liquid crystal display. Although these two methods can achieve the purpose of wireless transmission, the external method still takes up quite a lot of space, and it is not a true "no transmission line" state.

As far as the wireless transmission module built into the base of the large liquid crystal display is concerned, the wireless transmission module is built into the base instead of the LCM. In other words, the LCM and the wireless transmission module are still two independent components. Furthermore, the wireless transmission module has a relatively large volume, so it can only be used in large liquid crystal displays, but cannot be used in small liquid crystal display panels such as mobile phones.

To sum up, it is really necessary to improve the transmission mode of the existing liquid crystal display module.

Contents of the invention

1. The volume of the wireless transmission module and the microprocessor control unit is reduced, so that it can be directly integrated in the PCB or FPC of the liquid crystal display module (LCM), so that the composed liquid crystal display device has the function of wireless transmission, and the overall volume is smaller Small, low power consumption, easy to be applied to small devices such as mobile phones;

2. The wireless transmission module is set inside, so there is no need to consider the transmission line in the design of the liquid crystal display device, which can improve the design freedom of mobile phone products;

3. Since no transmission line is required, the problem of easy breakage of the transmission line in the prior art does not occur.
