Pulling type flexible screen

Abstract

The invention relates to the field of flexible electronic technologies, and discloses a pulling type flexible screen. The pulling type flexible screen comprises a shell and a support plate, wherein arolling cavity is arranged on one side of the shell; a rolling roller is installed in the rolling cavity; a flexible screen is arranged on the outer side wall of the rolling roller; one side of the flexible screen is fixedly connected with the support plate; and an adjustable protection roller is arranged between the support plate and the rolling roller. According to the pulling type flexible screen, a pulling part serves as an auxiliary display, touch control on the screen is mainly performed on an upper part of the pulling part fixed on the support plate; meanwhile, when the support plate ispulled, a movable support block is bounced automatically to be fit with a flexible screen, so as to support the pulling part, so that the pulling part is prevented from being concave due to the own weight or touch, and thus the display effect can be ensured, and the pulling part also can be applied to the touch operation; meanwhile, the flexible screen is always in a suspended state no matter inmoving or in rolling, friction and stress received by the flexible screen are reduced, and the pulling service life of the flexible screen is improved.

Description

technical field [0001] The invention relates to the technical field of flexible electronics, in particular to a pull-out flexible screen. Background technique [0002] The OLED screen uses a very thin organic material coating and a flexible substrate. When the current passes through, these organic materials will emit light, so that the OLED screen can be made lighter, thinner and fully functional. As its technology matures, its application fields will become more and more extensive. . [0003] see figure 1 , is an application solution for flexible screens. There is a rotating shaft in the middle to roll up the screen. When in use, the screen is pulled out by twitching, which reduces the space occupied by the screen and is more flexible to use. In order to facilitate the twitching of the screen, the screen itself and the supporting mechanism of the lower layer There is a lack of connection, and when the force is applied, the screen will be dented.

Problems solved by technology

[0003] see figure 1 , is an application solution for flexible screens. There is a rotating shaft in the middle to roll up the screen. When in use, the screen is pulled out by twitching, which reduces the space occupied by the screen and is more flexible to use. In order to facilitate the twitching of the screen, the screen itself and the supporting mechanism of the lower layer There is a lack of connection, and when the force is applied, the screen will be dented. It can be used on large-screen devices with less touch requirements, but there are obvious defects in the application on mobile phones, which will reduce the service life and the user experience is not good.

[0004] Furthermore, since the screen of the mobile phone will rub against the support structure at the bottom when the screen is twitching, the traction force during the twitching and the friction force between the bottom and the support mechanism will have a greater impact on the screen, further reducing the service life of the screen
