Abstract
The present disclosure provides an AMOLED display module and displaying method for operable in different bendable states, which the displaying state of a display panel can be directly controlled by a driver chip because a bending state sensor is disposed on a bendable region of the display panel and directly coupled with the driver chip. It increases the efficiency and compatibility.
Claims7
An active-matrix organic light emitting diode (AMOLED) module operable in at least two bendable states, comprising:
- a display panel, configured to display various display interfaces corresponding to different bendable states, said display panel comprising a bendable region;
- a driver chip, configured to determine a bending state of said display panel according to different electrical signals, and configured to control a displaying state of said display panel according to corresponding bending state, wherein said driver chip is disposed in said display panel and electrically coupled with said display panel;
- and
- a bending state sensor, configured to receive a pressure signal when said display panel is bended, to convert said pressure signal into said electrical signal and to transmit said electrical signal to said driver chip, wherein said bending state sensor is disposed on said bendable region;
- wherein said bending state sensor is electrically coupled with said driver chip through a flexible printed circuit board;
- wherein said AMOLED module further comprises a detecting circuit configured to detect the bending state of said AMOLED module, said detecting circuit comprises said driver chip, said bending state sensor and a resistor with a constant resistance, wherein said bending state sensor is a pressure sensor;
- wherein said bending state sensor comprises a first pin electrically coupled with a constant voltage output pin of said driver chip, and a second pin electrically coupled with a voltage detecting pin of said driver chip and said resistor that is electrically coupled to ground;
- wherein said flexible printed circuit board is electrically coupled with said display panel and is disposed on a backside of said display panel, and said bending state sensor is soldered on said flexible printed circuit board;
- wherein said bending states comprise an open state, a half open state, a first close state and a second close state;
- said open state means that said AMOLED module is flatten, said half open state means that two half panels of said AMOLED module are formed an obtuse angle or perpendicular to each other, said first close state means that said two half panels of said AMOLED module are folded as backside to backside, and said second close state means that said two half panels of said AMOLED module are folded as frontside to frontside;
- wherein said displaying states comprise a single manipulation interface state displayed on full panel corresponding to said open state, two manipulation interfaces state displayed on said two half panels corresponding to said half open state, a half panel off and half panel manipulation interface state corresponding to said first close state, and a full panel off state corresponding to said second close state.
