A dual-display mobile terminal

Abstract

The invention discloses a mobile terminal with dual display screens, comprising: a relatively rotating main casing and an auxiliary casing, a CPU arranged in the main casing; a first display screen and The second display screen, the first display screen and the second display screen are respectively connected to the CPU to correspond to different display applications; it is arranged on the back of the first display screen of the main casing and is close to the electromagnetic board of the first display screen; the said The electromagnetic board is connected to the CPU, and is used to detect the input track and send the input track to the CPU; wherein, the CPU is used to select the currently used display screen and send display data to the currently used display screen. The mobile terminal with dual display screens of the present invention has low cost, good body heat dissipation effect, high system 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 high-end color electronic ink screens have far less color saturation than LCD screens. Moreover, the biggest disadvantage of electronic ink screens is the slow refresh rate, which cannot satisfy users. Application requirements for watching 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 with a mobil...

Problems solved by technology

[0006] 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, because the user cannot use the two screens at the same time. Only one of the display screens can be selected at a time, which not only increases the material cost of the whole machine, but also reduces the utilization rate of the electromagnetic board, 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 better hand feeling. Good and fast text input method; the mobile terminal sandwiches the system motherboard and battery between two display screens instead of close to the casing, which will cause difficulty in heat dissipation of the motherboard, causing heat to accumulate in the body, resulting in temperature Elevated, affecting product stability
