CHERLYNN LOW: Intel
surprised us last Computex

2
00:00:02,070 --> 00:00:04,170
with unique
prototype dual-screen

3
00:00:04,170 --> 00:00:08,460
devices like the Tiger Rapids
concept with an E ink screen.

4
00:00:08,460 --> 00:00:11,010
This year, the company has
even more to show off here

5
00:00:11,010 --> 00:00:12,720
at its technology open house.

6
00:00:12,720 --> 00:00:15,390
These dual screen devices
demonstrate the ability

7
00:00:15,390 --> 00:00:18,780
of Intel's eighth gen and
newer core processors,

8
00:00:18,780 --> 00:00:21,610
and the ability of them to
power such resource-intensive

9
00:00:21,610 --> 00:00:22,410
devices.

10
00:00:22,410 --> 00:00:26,040
But it's more than just
a proof of concept.

11
00:00:26,040 --> 00:00:28,200
At the risk of sounding
a little too hype,

12
00:00:28,200 --> 00:00:31,980
I think these demos are very
telling of the exciting future

13
00:00:31,980 --> 00:00:32,820
of PCs.

00:00:36,250 --> 00:00:37,720


16
00:00:37,720 --> 00:00:40,280
The Twin Rivers
prototype in particular

17
00:00:40,280 --> 00:00:43,820
is the second generation of
such a dual-screen prototype

18
00:00:43,820 --> 00:00:45,050
we've seen from Intel.

19
00:00:45,050 --> 00:00:47,030
And so it makes
sense that the device

20
00:00:47,030 --> 00:00:48,320
feels a little more mature.

21
00:00:48,320 --> 00:00:51,480
Don't get me wrong, it's
still a little buggy.

22
00:00:51,480 --> 00:00:53,930
It did refuse to
cooperate sometimes.

23
00:00:53,930 --> 00:00:57,260
But at least the screen was a
lot more vibrant than before

24
00:00:57,260 --> 00:00:58,910
and actually looked really nice.

25
00:00:58,910 --> 00:01:02,690
That's important since screens
are basically the main feature

26
00:01:02,690 --> 00:01:03,710
of Twin Rivers.

27
00:01:03,710 --> 00:01:07,700
The Twin Rivers prototype itself
packed two 12.3-inch screens

28
00:01:07,700 --> 00:01:11,310
running at 1920 by
1280 resolutions,

29
00:01:11,310 --> 00:01:14,990
which gives them an aspect
ratio of three by two.

30
00:01:14,990 --> 00:01:17,900
They could be set up in all
kinds of configurations.

31
00:01:17,900 --> 00:01:20,510
Like any 2-in-1, you could
use this in tent mode,

32
00:01:20,510 --> 00:01:23,360
for example to show a
presentation to the people

33
00:01:23,360 --> 00:01:24,620
sitting across from you.

34
00:01:24,620 --> 00:01:27,740
You can also use it like
you would a typical laptop

35
00:01:27,740 --> 00:01:29,990
and have the bottom screen
display a customized

36
00:01:29,990 --> 00:01:31,820
version of the
Microsoft keyboard

37
00:01:31,820 --> 00:01:34,340
with even a trackpad
on the screen.

38
00:01:34,340 --> 00:01:37,730
So you can fire out a
quick message or an email.

39
00:01:37,730 --> 00:01:41,270
But if you want a more natural,
intuitive typing experience,

40
00:01:41,270 --> 00:01:44,150
you can always connect
a wireless keyboard.

41
00:01:44,150 --> 00:01:47,000
The nice thing about the
keyboard with the prototype

42
00:01:47,000 --> 00:01:48,950
here at the show was
that you can actually

43
00:01:48,950 --> 00:01:52,430
put the very thin
keyboard accessory on top

44
00:01:52,430 --> 00:01:54,650
of the bottom display,
and then snapshot

45
00:01:54,650 --> 00:01:57,060
the Twin Rivers
prototype and just take

46
00:01:57,060 --> 00:01:57,960
the whole package with you.

47
00:01:57,960 --> 00:01:59,960
The keyboard actually
fits in there pretty

48
00:01:59,960 --> 00:02:01,820
snugly and doesn't fall out.

49
00:02:01,820 --> 00:02:04,010
And the whole thing
just feels like a folio.

50
00:02:04,010 --> 00:02:06,620
But the real benefit of
having the two screens

51
00:02:06,620 --> 00:02:09,850
is obviously really
powerful multitasking.

52
00:02:09,850 --> 00:02:11,960
You can actually look at
a video on the top screen

53
00:02:11,960 --> 00:02:14,570
while taking notes on
the bottom with a stylus.

54
00:02:14,570 --> 00:02:17,510
Or run different apps
at the same time-- maybe

55
00:02:17,510 --> 00:02:19,100
you have Slack on
the bottom screen

56
00:02:19,100 --> 00:02:21,320
while you're working on
your article or essay

57
00:02:21,320 --> 00:02:22,640
at the top screen.

58
00:02:22,640 --> 00:02:26,030
You can also lift up
this dual-screen device

59
00:02:26,030 --> 00:02:29,630
and hold it as you would a book
and then read comics on it.

60
00:02:29,630 --> 00:02:31,400
Or maybe check out some recipes.

61
00:02:31,400 --> 00:02:33,590
The applications that
Intel had on show

62
00:02:33,590 --> 00:02:36,290
here weren't actually
full-fledged apps.

63
00:02:36,290 --> 00:02:39,350
They're just ways that Intel
hopes to inspire developers

64
00:02:39,350 --> 00:02:41,120
to make use of the
new form factor

65
00:02:41,120 --> 00:02:43,760
to come up with creative
uses of such modes.

66
00:02:43,760 --> 00:02:46,700
You can also take
notes in book mode

67
00:02:46,700 --> 00:02:48,860
as well, which, given
that the prototype

68
00:02:48,860 --> 00:02:50,390
device was slightly
heavy, I didn't

69
00:02:50,390 --> 00:02:52,190
really want to do very much.

70
00:02:52,190 --> 00:02:54,747
But in the future when
an OEM, for example,

71
00:02:54,747 --> 00:02:55,880
takes this idea
and runs with it--

72
00:02:55,880 --> 00:02:58,820
it makes a very lightweight
device in such a form--

73
00:02:58,820 --> 00:03:02,870
it could really make
dual-screen note taking with one

74
00:03:02,870 --> 00:03:05,120
hand an the actual possibility.

75
00:03:05,120 --> 00:03:06,890
On the outside of
these prototype

76
00:03:06,890 --> 00:03:10,370
devices is a sort of soft fabric
covering that not only makes

77
00:03:10,370 --> 00:03:12,380
the device feel a
bit more book-like,

78
00:03:12,380 --> 00:03:15,230
but it also is supposed
to help keep things cool.

79
00:03:15,230 --> 00:03:18,290
This is a fan-less design,
so obviously heat dissipation

80
00:03:18,290 --> 00:03:19,700
is very important here.

81
00:03:19,700 --> 00:03:22,310
It is after all powering
two whole screens.

82
00:03:22,310 --> 00:03:25,610
Since this is just a prototype
concept thing that really isn't

83
00:03:25,610 --> 00:03:27,920
going to hit the market, I'm
not going to bother telling you

84
00:03:27,920 --> 00:03:29,570
about how many ports it has.

85
00:03:29,570 --> 00:03:32,090
There is a USB-C here that
they're using for charging

86
00:03:32,090 --> 00:03:33,530
up with power and stuff.

87
00:03:33,530 --> 00:03:36,480
And one of these actually
has LTE built in.

88
00:03:36,480 --> 00:03:38,900
So there's actually a
lot of different ways

89
00:03:38,900 --> 00:03:41,480
that manufacturers
could customize

90
00:03:41,480 --> 00:03:44,210
these types of devices and make
them even more useful for you.

91
00:03:44,210 --> 00:03:47,150
But we really won't know
until we see these in reality,

92
00:03:47,150 --> 00:03:48,230
out in the real world.

93
00:03:48,230 --> 00:03:51,290
But the biggest question
about dual-screens

94
00:03:51,290 --> 00:03:54,170
is and always will
be power consumption.

95
00:03:54,170 --> 00:03:56,270
And that's something
that Intel is working on

96
00:03:56,270 --> 00:03:57,800
and also understands
is basically

97
00:03:57,800 --> 00:03:59,120
the most important thing here.

98
00:03:59,120 --> 00:04:01,220
There are three ways that
Intel can tackle this problem.

99
00:04:01,220 --> 00:04:03,140
The first of which
being the low power

100
00:04:03,140 --> 00:04:05,240
display type that it
unveiled last year.

101
00:04:05,240 --> 00:04:08,960
Now, because the right size
screens with low power display

102
00:04:08,960 --> 00:04:11,780
tech aren't available for
this particular prototype yet,

103
00:04:11,780 --> 00:04:13,610
Intel didn't integrate it.

104
00:04:13,610 --> 00:04:15,950
But there's nothing stopping
third-party manufacturers

105
00:04:15,950 --> 00:04:18,500
from using that technology
in their actual devices.

106
00:04:18,500 --> 00:04:20,750
But aside from the
screen tech, the CPUs

107
00:04:20,750 --> 00:04:24,050
are also built for
power efficiency

108
00:04:24,050 --> 00:04:25,880
so that your battery
can last a lot longer.

109
00:04:25,880 --> 00:04:28,880
With something that Intel
is calling dynamic tuning,

110
00:04:28,880 --> 00:04:32,660
the CPU will, based on what
you're using the laptop for,

111
00:04:32,660 --> 00:04:36,560
try to prioritize performance
or power efficiency.

112
00:04:36,560 --> 00:04:39,290
And therefore make your
battery last a lot longer.

113
00:04:39,290 --> 00:04:42,200
With dual-screen devices,
there's also ways to squeeze

114
00:04:42,200 --> 00:04:44,090
in more battery into them.

115
00:04:44,090 --> 00:04:46,220
With the Twin Rivers
device, Intel actually

116
00:04:46,220 --> 00:04:48,860
built in battery into both
the bottom and the top halves

117
00:04:48,860 --> 00:04:49,760
of the device.

118
00:04:49,760 --> 00:04:52,010
Even with all of these
power management tricks,

119
00:04:52,010 --> 00:04:54,320
Intel admits there
might be some trade-off

120
00:04:54,320 --> 00:04:56,420
when it comes to battery life.

121
00:04:56,420 --> 00:04:59,120
But the idea here is that
you're getting so much

122
00:04:59,120 --> 00:05:02,270
from the dual-screen setup
that that's a compromise

123
00:05:02,270 --> 00:05:03,590
you might be willing to make.

124
00:05:03,590 --> 00:05:06,170
Still though, even
as just concepts,

125
00:05:06,170 --> 00:05:08,480
we have seen Intel
and its partners

126
00:05:08,480 --> 00:05:11,810
take novel form factors and
push them out to the market.

127
00:05:11,810 --> 00:05:14,600
For example, Asus'
ZenBook Pro Duo is already

128
00:05:14,600 --> 00:05:17,360
a working version of the
Honeycomb Glacier concept

129
00:05:17,360 --> 00:05:18,730
that they showed off here.

130
00:05:18,730 --> 00:05:22,040
And last year's Yoga Book
was also a dual-screen device

131
00:05:22,040 --> 00:05:24,200
that did go on for sale.

132
00:05:24,200 --> 00:05:27,210
Intel also tossed around the
word foldable a bunch of times

133
00:05:27,210 --> 00:05:28,010
here.

134
00:05:28,010 --> 00:05:30,590
That seems to be the
direction towards which

135
00:05:30,590 --> 00:05:32,390
Twin Rivers might be headed.

136
00:05:32,390 --> 00:05:34,490
Or at least branched
off towards.

137
00:05:34,490 --> 00:05:36,800
And we've already
seen that Lenovo

138
00:05:36,800 --> 00:05:40,810
is prepping the world's first
laptop with a foldable screen.

139
00:05:40,810 --> 00:05:43,240
So even though these are
all just concepts right now,

140
00:05:43,240 --> 00:05:47,860
they are a very good sign
that the PC industry is headed

141
00:05:47,860 --> 00:05:49,630
somewhere extremely exciting.

142
00:05:49,630 --> 00:05:53,050
For all of that news and
more out of Computex 2019,

143
00:05:53,050 --> 00:05:54,310
