Dual-display mobile terminal

Abstract

The invention discloses a dual-display mobile terminal which comprises a main housing and an auxiliary housing that rotate mutually oppositely. The dual-display mobile terminal also comprises a CPU arranged in the main housing, an electronic ink screen and a liquid crystal display which are arranged on the auxiliary housing in a back-to-back manner, an electromagnetic plate arranged between the electronic ink screen and the liquid crystal display, wherein the electronic ink screen and the liquid crystal display are connected with the CPU so as to correspond to different display applications; the electromagnetic plate is connected with the CPU and used for detecting input track information and sending the input track information to the CPU; and the CPU is used for selecting the currently-used display and sending display data to the currently-used display. The dual-display mobile terminal has the advantages of low cost, good heat radiating effect, high stability and long service life.

Description

technical field [0001] The present invention relates to a mobile terminal, in particular to a mobile terminal with dual display screens. Background technique [0002] Electronic ink display (EPD), as a display screen specially used for reading electronic books and documents, has obvious advantages such as large viewing angle reading, green environmental protection, eye protection, and ultra-low power consumption. But at present, ordinary electronic ink screens can only support 16-level grayscale display. Even the color saturation of high-end color electronic ink screens is far lower than that of LCD screens. Moreover, the biggest disadvantage of electronic ink screens is the slow refresh rate, which cannot meet Application requirements for users to watch videos, games, and real-time interaction. [0003] As a new portable mobile terminal, a tablet computer equipped with a large-size liquid crystal display (LCD) has begun to enter the consumer electronics market. Compared wi...

Problems solved by technology

[0007] Although this kind of mobile terminal combines liquid crystal display and electronic ink screen to realize the complementary advantages of the two screens, it has the following defects: two electromagnetic boards are used for the two display screens respectively, since the user does not need to use the two screens at the same time. Only one display screen can be selected at a time, which not only increases the material cost of the whole machine, but also makes the utilization rate of the electromagnetic board low, and is not conducive to reducing the thickness of the fuselage; moreover, the mobile terminal cannot add a physical keyboard and cannot provide users with a hand feel. A better and fast way of text input; the mobile terminal sandwiches the system motherboard and battery between the two display screens instead of close to the casing, which will cause difficulty in cooling the motherboard and cause heat to accumulate in the body, resulting in Increased temperature affects product stability
