MIPI Alliance Standard for Display Pixel Interface 62
1 Overview 63
This document describes Display Pixel Interface (DPI), which is used for Active-Matrix LCD displays for 64
handheld devices. The interface may be configured with data path of 16, 18 or 24 parallel data bits, and 65
several control signals. 66
This document specifies the interface requirements for both ends (host and display) of the link, including 67
the following attributes: 68
• Electrical 69
• Timing 70
• Pixel formats (mapping of pixel bits to data signals) 71
• Command set to control display behaviors 72
1.1 Scope 73
The scope of this document is to specify an electrical and logical interface between a host system 74
(processor or controller) and an active-matrix (AM) display module. The specification is intended for 75
display modules in mobile devices, with display resolution up to 800x480 pixels. This specification does 76
not apply to passive-matrix display modules. 77
Included, and within the scope of this specification, is the power supply for interface signaling between the 78
host processor and the display module. However, power supply for other functions in the display module 79
are beyond the scope of this specification. 80
1.2 Purpose 81
The Display Pixel Interface specification is used by manufacturers to design products that adhere to MIPI 82
specifications for mobile device processor, camera and display interfaces. 83
Implementing the DPI standard reduces the time-to-market and design cost of mobile devices by 84
simplifying the interconnection of products from different manufacturers. In addition, adding new features 85
such as larger or additional displays to mobile devices is simplified due to the extensible nature of the MIPI 86
specifications. 87

2 Terminology 88
2.1 Definitions 89
Command: Digital information used to control display behavior and to identify the connected display 90
module 91
Data: Digital image data stored in the frame memory or numerical information to define the display 92
module behavior accompanied with a command 93
Display Controller: Isolated IC silicon chip or integrated functional block in the host processor to control 94
a display module; may or may not include frame memory 95
Display Device: Functional device which can show image, such as Liquid Crystal Displays 96
Display Driver IC: IC silicon chip in a display module used to control the display device; may or may not 97
include frame memory 98
Display Glass: Same as display device, coming from material name 99
Display Module: Functional module to show image on it, can consists of display device, display driver IC, 100
other peripheral components and circuits and display interface 101
Display Panel: Same as Display Device, coming from the physical outward appearance of the display 102
device 103
Frame Memory: Memory device integrated in a display driver IC or display controller in order to provide 104
image data for refreshing the display device. Full-frame memory provides a full screen area of image data 105
while partial-frame memory only provides memory for a portion of the screen area. 106
Type 1 Display Architecture: One of the defined display module architectures. In DSI, DBI, DPI, and 107
DCS, a display module architecture in which a display module includes a display device, display driver IC, 108
full-frame memory, registers, timing controller, non-volatile memory and control interface. 109
Type 2 Display Architecture: One of the defined display module architectures. In DSI, DBI, DPI, and 110
DCS, a display module architecture in which a display module includes a display device, display driver IC, 111
partial-frame memory, registers, timing controller, non-volatile memory, control interface and video stream 112
interface. 113
Type 3 Display Architecture: One of the defined display module architectures. In DSI, DBI, DPI, and 114
DCS, a display module architecture in which a display module includes a display device, display driver IC, 115
registers, timing controller, non-volatile memory, control interface and video stream interface. 116
Type 4 Display Architecture: One of the defined display module architectures. In DSI, DBI, DPI, and 117
DCS, a display module architecture in which a display module includes a display device, display driver IC, 118
registers, timing controller, control lines and video stream interface. 119
2.2 Abbreviations 120
High-Z High Impedance 121
H-Sync Horizontal Synchronization 122
